The term zooplankton is used to describe a large number of creatures; the exact definition is any animal that cannot move against a sustained current in the marine environment. There are two main types of plankton: holoplankton and meroplankton. Meroplankton are organisms that are plankton for only part of their life cycle. So this makes most sea creatures plankton, for instance, salmon, sunfish, tuna, and most other fish are meroplankton because they start out their lives as plankton. Holoplankton are plankton that remain plankton for their whole lives, these include mysid shrimp, most marine worms, and most jellyfish.
I have spent a good deal of time this summer looking through a microscope at the zooplankton we have captured during sampling from our research kayak, trying to distinguish and identify different species. Telsons, the tail of the tail, are what we use to identify different types of mysid shrimp, which are a primary gray whale prey item along the Oregon coast and the most predominant type of zooplankton we capture in our sampling. For instance Neomysis is a genus of mysid shrimp and is one of the two most abundant zooplankton species we get. Their telsons end with two spikes that are somewhat longer than the spikes on the side of the telson. This look is distinct from Holmesimysis sculpta, the other of the two most abundant zooplankton species we get, which have four-pronged telsons with varying sizes of spikes along the sides of the telson. Alienacanthomysis macropsis is identified by both their long eye stalks and their rather bland rounded telson.
However, creatures that are not mysid shrimp cannot be identified this way. Like gammarids, they look like fleas. We have only found one kind of gammarid here in Port Orford this year, Atylus tridens. There are other types but that is the only type we have found this year. After that, we have Caprellidae, also known as skeleton shrimp. They are long and stalky, and have claws in every spot where they could have claws.
Then there are copepods. Copepods are tiny and have long antennae that string down to the sides of their bodies. We also have been seeing lots of crab larvae. I have also seen a couple of polychaete worms, which are marine worms with many legs and segments. The only reason I was able to identify them as polychaetes is due to my marine biology class at Astoria High School where we identified these worms using microscopes before.
We also have had some trouble identifying somethings. For instance, we have found a few individuals of a type of mysid shrimp with a rake-like tail that we are still trying to identify. Also, we have captured some jellyfish that we are not trying to identify. When the kayak team gets back in from gathering samples, we freeze the samples to kill and preserve the critters in them. This process turns the jellyfish to mush, so they are hard to identify.
To identify these zooplankton and other critters, we put them into a Petri dish and under a dissection scope, at which point we use forceps to move and pivot creatures. If a jellyfish had just eaten another plankton, we have to cut it open to get the plankton out so we can identify it.
Sometimes we have large samples of thousands of the same creature, in this case, we would normally sub-sample it. Sub-sampling is when we take a portion of a sample and identify and count individual zooplankton in that sub-sample. Then we multiply those counts by the portion of the whole sample to get the approximate total number that are in that sample. For instance, say we had a rather large sample, we would take a tenth of that sample and count what is in it. Say we count 500 individuals in that tenth. We would then multiply 500 by ten to get the total number in that whole sample.
Then there are some plankton that we do not catch, like large jellyfish. The kayak team has gotten photos of a giant jellyfish that was nearly a meter long.
All in all, Port Orford has an amazing and diverse population of marine life. From gray whales to thresher sharks to mysid shrimp to copepods to jellyfish, this little ecosystem has pretty much some of everything.

Murphy’s Law says that “things will go wrong in any given situation if you give them a chance”. This statement certainly applies to research where you never really know what is going to happen when performing fieldwork. You can only try to be prepared for all of the situations. When I arrived at the Oregon State University (OSU) Field Station in Port Orford, I had no idea that it would harbor some of the best educational experiences I have ever had. I had no idea what a theodolite was, nor did I know how to kayak in the ocean, but I learned fast. When we first started being trained on using a theodolite and the program that processes the data, Pythagoras, we had some problems. The theodolite would not stay level, but just as we were learning how to work the theodolite, we also learned how to work as a team. When we finally managed to level the theodolite, which did take a few days, I began to realize the hard work of doing fieldwork. You can be prepared but there will always be something that goes wrong, and that’s okay. I have learned that mistakes happen and cannot be dwelled on. Only learned from. No one is perfect.
Just two days ago I was on our tandem research kayak with Mia Arvizu, the OSU Marine Studies Initiative (MSI) undergraduate intern. When we go out on the kayak, we paddle around our study area and go to GPS-marked “stations” to collect prey samples of zooplankton, test for water visibility using a Secchi disk, and send a GoPro underwater to have a better understanding of what is going on under the surface. While sampling at Station 15 in Mill Rocks I lowered the GoPro into the water using a downrigger. When the GoPro reached the bottom, I began to pull it up, only to realize it had gotten snagged in a crevice. I gave the line to which the GoPro is attached some slack and began to give Mia instructions to move to different spots to try and retrieve the GoPro out of this tight crevice. Unfortunately, I did not realize all of the lines had wrapped themselves underneath the downrigger and as soon as a swell came up, the line broke. My eyes widened as I realized what had just happened. Thankfully, I managed to grasp the last of the remaining line left connected to the GoPro and pulled it back into the kayak using my hand wrapped in a towel since the line is thin and can cut into your hands easily. Only then did I realize that neither Mia nor I had packed a knife in the event we needed to cut a line. We sat and pondered ideas of how to cut the last of the line so that I could reattach the GoPro to the downrigger. Mia came up with the idea to use a barnacle or a mussel, and it worked perfectly. We were proud of ourselves for being resourceful and using nature to our advantage. But as soon as I finished using the mussel to cut the line, Lisa’s voice came over the VHF radio that we always carry with us in the kayak that there were scissors in the First Aid Kit that is stowed in the dry hatch of the kayak. Mia and I looked at each other and could only laugh. The kayak team can be rough at times but it’s made up by the fact that we get beautiful prey samples and stunning GoPro videos of what is below the water.
After all of the kayak sampling is done we organize and store our gear, and then go to the lab. In the lab, one person will clean all tools and devices touched by saltwater while the other sieves all of our zooplankton samples. Each sample is individually sieved and then placed in a sample jar with its station name on it and placed into the freezer. We put them in the freezer to increase the longevity of the samples, as well as euthanizing all zooplankton so that they are easier to identify under a dissection scope. After all of that is done we take a 45-minute break before taking over the cliff team job so they can have a lunch break, as well as a rest from staring at the glare of the water all day searching for whales.
The cliff team generally consists of two people. One person will be on the theodolite, and the other will be on the laptop. The idea is that the theodolite uses the Pythagorean Theorem to get the exact coordinates of the whale we are spotting. This allows us to track exactly where the whales are going, what they are doing, how they’re doing it, and the fashion in which they’re doing it. The fixed points will fall on a plotted map on the laptop. The other job of the person on the laptop is to take pictures when possible so we can identify the whales. For instance, there is a whale named Buttons that has been recorded during past summers in Port Orford. By using the photos we take of a whale, combined with previous data about the whale named Buttons, we can cross-reference the body color and patterns of the whale to be able to re-identify Buttons. We now know that we have seen Buttons for 4 consecutive days feeding in our study area. The camera also acts as a tool to take pictures of whales not just for identity but for rare activity. Today while on the cliff Mia and I spotted a whale in Tichenor Cove (one of our sampling sites) that breached four times! These experiences are rare and beautiful. You never think about how big a whale truly is until you see it almost completely leap out of the water – it is beautiful.
I’m sure more mistakes will be made but that’s okay. I have many more experiences to witness, and many more memories to make from this internship, as well as challenges. I couldn’t be more than happy with the team I have to share all of these learning experiences and hardships with.

As I enter my second term at OSU as a Master’s student, the ideas and structure of my thesis are slowly coming together. As of right now, my plan is to have two data chapters: The first chapter will assess the quality of zooplankton prey gray whales have access to along the Oregon coast, by looking at energetic value and microplastic content. I will contemplate about how my results potentially affect gray whale health. The second chapter will investigate fine-scale foraging and space use of gray whales in the Port Orford area to determine whether individual specialisation exists.
When I first started digging into the scientific literature to prepare for writing my thesis proposal (which is still underway but I’m getting close to the end of a first draft…), one sentence that I seemed to stumble across more often than not was “Marine plastics are ubiquitous” or “Plastics have become ubiquitous in the marine environment” or some other, very similar, iteration of that statement (e.g. Machovsky-Capuska et al. 2019; Eriksen et al. 2014; Fendall & Sewell 2009).
Many of the papers I first read were review papers on microplastics that mostly discussed general concepts like dispersal mechanisms, trophic transfer, or how microplastics become degraded. While I often think of review papers as treasure chests, since they neatly and succinctly summarise an often complicated and busy area of research into just a few pages, sometimes the fine-scale detail can go missing. Therefore, when reading these review papers, I wasn’t learning the in depth details about specific studies where microplastics had been detected in a group of individuals, population or species. So I felt the statement “Plastics are ubiquitous” was just a good (and pretty dramatic) opening line for a paper. However, once I delved into the studies on single species, I was overwhelmed by the amount of results that GoogleScholar spit out at me. If you type “microplastics marine” into the search bar, you’ll get about 7,650 results. This amount might not sound like a lot, especially if you compare it to say “gray whale”, which generates 96,600 results. Yet, the microplastic extraction method typically used was only developed in 2004 (Thompson et al. 2004). Hence, in a span of just 15 years, over 7,000 studies have detected microplastics in over 660 marine organisms (Secretariat of the Convention on Biological Diversity 2012) – a fact I find extremely troubling.
Microplastics are most commonly viewed as particles <5 mm in size (though there is some contention on this size classification, e.g. Claessens et al. 2013). Microplastics arise from several sources, including fragmentation of larger plastics by UV photo-degradation, wave action and physical abrasion, loss of pre-production pellets (nurdles) and polystyrene beads from shipping vessels, waste water discharge containing microbeads used in cosmetics and microfibers released during the washing of textiles and run-off from land (Nelms et al. 2018). Their small size makes these persistent particles bioavailable to ingestion by a variety of marine taxa, ranging from small prey organisms such as zooplankton, to large megafauna such as whales.
Zooplankton are at the base of marine food webs and are therefore consumed in large quantities by a large number of consumers. The propensity of zooplankton to feed in surface waters makes them highly susceptible to encountering and ingesting microplastics as this is where these synthetic particles are highly abundant (Botterell et al. 2018). Microplastics have been detected in zooplankton from the Northeast Pacific Ocean (Desforges et al. 2015), northern South China Sea (Sun et al. 2017), and Portuguese coast (Frias et al. 2014). Additionally, there is documented overlap between microplastic and zooplankton occurrence at many more locations (e.g. North Western Mediterranean Sea, Collignon et al. 2012; Baltic Sea, Gorokhova 2015; Arctic Ocean, Lusher et al. 2015a). As microplastics research is still in its relative infancy, the extent to which microplastics are ingested by zooplankton and the consequences of this behaviour are uncertain. Nevertheless, exposure to microplastics could lead to entanglement of particles within feeding appendages and/or block internal organs, which may result in reduced feeding, poor overall health, injury and death (Desforges et al. 2015). Though a lab study has found that microplastics are expelled by zooplankton after ingestion, the gut-retention times varied between species, and there is the potential risk of exposure to toxins that leech off of particles while in the body (Cole et al. 2013; the below video is from the afore-mentioned study showing how plankton eat plastics, which are illuminated in fluorescent green).
The large knowledge gap regarding the health implications indicates a strong need for more laboratory studies that investigate the long-term effects of persistent exposure to microplastics on lower trophic organisms, as well as continued short-term experiments that examine whether different zooplankton species are affected differently, since morphologies and life-histories vary widely.
Let’s take a step back and re-focus our lens onto a marine taxa that is much, much bigger in size than a zooplankton: cetaceans. Plastic debris has been documented in the stomachs of stranded individuals of several cetacean species (See Baulch & Perry 2014 for a review), however findings of microplastics in cetaceans are less common. Since cetaceans consume large amounts of prey a day, up to several tons daily for some baleen whales, the likelihood that they are ingesting microplastics through their prey is relatively high (Nelms et al. 2018). Therefore the low number of reported cases is again likely due to the relative novelty of microplastic detection methods. Despite the paucity of studies, microplastics have been found in a True’s beaked whale (Mesoplodon mirus, Lusher et al. 2015b), a humpback whale (Megaptera novaeangliae, Besseling et al. 2015) and an Indo-Pacific humpback dolphin (Sousa chinensis, Zhu et al. 2018), showing that microplastic ingestion by cetaceans does occur. Whether these individuals actively (i.e. active feeding) or passively (i.e. uptake through prey consumption) consumed the microplastics, or inhaled them at the water-air interface, is unknown. As with zooplankton, the short- and long-term impacts of ingesting microplastics by marine mammals is also unknown, though impacts on survival, feeding and uptake of toxins are all possibilities.
The data collection and analysis I am doing for my thesis will hopefully fill small pockets in these large knowledge gaps. I hope to be able to quantify the extent of microplastic pollution among zooplankton species in nearshore Oregon waters. By comparing samples from several years, months and locations, I will determine whether microplastic loads vary spatially and temporally. Since their abundance and presence have been described as being patchy due to the influence of oceanographic and weather conditions (GESAMP 2016), it would seem reasonable to assume that there will be variation. But, results are a ways away as we have not even started our microplastic extraction techniques, which involves digesting samples in potassium hydroxide solution, incubating them at 50ºC for 48-72 hours, sorting through the dissolved material to identify potential plastics and sending them away for analysis. We first have to work our way through jars upon jars of unopened zooplankton light trap samplesthat need to be sorted by species. I am thankfully joined by undergraduate Robyn Norman who has already assisted this project immensely over the last two years with her zooplankton sorting prowess. So in case anyone wants to come looking for us over the next few weeks, you’ll find both Robyn and me sitting in front of a laminar flow hood in the lab of ecotoxicologist Dr. Susanne Brander, with whom we are collaborating on the microplastics portion of my thesis.

To many people, six weeks may seem like a long time. Counting down six weeks until your favourite TV show airs can feel like time dragging on slowly (did anyone else feel that way waiting for Blue Planet II to be released?). Or crossing off the days on your calendar toward that much-needed holiday that is still six weeks away can feel like an eternity. It makes sense that six weeks should feel like a long time. After all, six weeks are approximately a ninth of an entire year. Yet, I can assure you that if you asked anyone on my research team this summer whether six weeks was a long time, they would all say no.
As I watched each of my interns present our research to a room of 50 engaged community members (Fig. 1) after our six week research effort, I couldn’t help but feel an overwhelming sense of pride for all of them at how far they had come during the course of the field season.
On the very first day of our two-week training back in July, I gave my team an introductory presentation covering gray whales, their ecology, what the next six weeks would look like, how this project had developed and its results to date (Quick side-note here: I want to give a huge shout out to Florence and Leigh as this project would not be what it is today without their hard work and dedication as they laid the groundwork for it three years ago and have continued to improve and expand it). I remember the looks on my interns’ faces and the phrase that comes to mind is ‘deer in headlights’. It isn’t surprising that this was the case as this internship was the first time any of them had done marine mammal field work, or any kind of field work for that matter. It makes me think back to my first taste of field work. I was a fresh high school graduate and volunteering with a bottlenose dolphin research group. I remember feeling out of place and unsure of myself, both in terms of data collection skills but also having to live with the same people I had worked with all day. But as the first few days turned into the first few weeks, I grew into my role and by the end of my time there, I felt like an expert in what I was doing. Based on the confidence with which my interns presented our gray whale foraging ecology research to an audience just over a week ago, I know that they too had become experts in these short six weeks. Experts in levelling a theodolite, in sighting a blow several kilometres out from our cliff site, in kayaking in foggy conditions, in communicating effectively in high stress situations – the list goes on and on.
While you may have read the previous blog posts written by each of my interns in the last four weeks and thus have a sense of who they are, I want to tell you a little more about each of these hardworking undergraduates that played a large role in making this year’s Port Orford gray whale season so effective. Although we did not have any local high school interns this year, the whole team hails from Oregon, specifically from Florence, Sweet Home and Portland.
Haley Kent (Fig. 2), my co-captain and Marine Studies Initiative (MSI) intern, an Environmental Science major, is going into her senior year at OSU this fall. She is focused and driven, which I know will enable her to pursue her dream of becoming a shark researcher (I can’t even begin to describe her excitement when we saw the thresher shark on our GoPro video). I couldn’t have asked for a better right hand person for my first year taking over this project and I am excited to see what results she will reveal through her project of individual gray whale foraging preferences. Also, Haley has a big obsession for board games and provided the team with many evenings of entertainment thanks to Munchkin and King of Tokyo.
Dylan Gregory (Fig. 3) is transferring from Portland Community College and is going to be an OSU junior this fall. Not only was Dylan always extremely helpful in working with me to come up with ways to troubleshoot or fix gear, but his portable speaker and long list of eclectic podcasts always made him a very good cliff team partner. He was also Team Whale Storm’s main chef in the kitchen, and while some of his dishes caused tears & sweat among some team members (Dylan is a big fan of spices), there were never any leftovers, indicating how delicious the food was.
Robyn Norman (Fig. 4) will be a sophomore at OSU this fall and her commitment to zooplankton identification has been invaluable to the project. Last year when she was a freshman, Robyn was given our zooplankton samples from 2017, a few identification guides and instructions on how to use the dissecting microscope, before she was left to her own devices. Her level of independence and dedication as a freshman was incredible and I am very grateful for the time and skills she has given to this work. Besides this though, Robyn always brought an element of happiness to the room and I can speak on behalf of the rest of the team, that when she was gone for a week on a dive trip, the house did not feel the same without her.
Hayleigh Middleton (Fig. 5), a fresh high school graduate and freshly turned 18 during the project, is starting as a freshman at OSU this fall. She is extremely perceptive and would (thankfully) often remind others of tasks that they had forgotten to do (like take the batteries out of the theodolite or to mention the Secchi depth on the GoPro videos). I was very impressed by Hayleigh’s determination to continue working on the kayak despite her propensity for sea sickness (though after a few days we did remedy this by giving her raw ginger to chew on – not her favourite flavour or texture but definitely very, very effective!). She is inquisitive about almost everything and I know she will do very well in her first year at OSU.
Thank you, Team Whale Storm (Fig. 6), for giving me six weeks of your summer and for making my first year as project leader as seamless as it could have been! Without each and every one of you, I would not have been able to survey for 149.2 hours on the cliff, collect over 300 zooplankton samples, identify 31 gray whales, or launch a tandem kayak at 6:30 am every morning.
My interns were not the only ones to experience many “firsts” during this field season. I learned many new things for the first time right alongside them. While taking leadership is not a foreign concept to me, these six weeks were my first real experience of leading a project and a team for a sustained period of time. Managing teams, delegating tasks and compiling data felt gratifying because I felt like I was exactly where I should be (Fig. 7).
I dealt with many daunting tasks, yet thanks to the support of my interns, as well as Tom (Port Orford field station’s incredible station manager), Florence and Leigh, I learned how to resolve my problems: I fixed and replaced broken or lost gear (I am not a very mechanically inclined person; Fig. 8), budgeted food for five hungry people doing tiring field work (I’ve only ever budgeted for one person previously), and taught people how to use gear that I had not often used before (I can say now that the theodolite and I are friends, but this wasn’t the case for the first few weeks…).
In the lead up to the summer field season this year, Leigh said to me, in one of the many emails we exchanged, that leading the project was a big task but that it was just six weeks long. She suggested that I rest up and get organised as much as I could ahead of time because, after all, the data collected this summer was going to be my thesis data, so I would want it to be as good as possible. Looking back, she couldn’t have been more right – the six weeks simply flew by, I did need the rest she had advised, and it definitely was a big task. I can’t wait for it to happen all over again next summer.

Although the average human may think all zooplankton are the same, to a whale, not all zooplankton are created equal. Just like us, different whales tend to favor different types of food over others. Thus, creating a meal perfect for each individual preference. Using a plankton net off the side of our kayak, each day we take different samples, hoping to figure out more about prey and what species the whales, we see, like best. These samples are then transported back to the lab for analysis and identification. After almost a year of identifying zooplankton and countless hours of looking through the microscope you would think I would have seen everything these tiny organisms have to offer. Identifying mysid shrimp and other zooplankton to species level can be extremely difficult and time consuming, but equally rewarding. Many zooplankton studies often stop counting at 300 or 400 organisms, however in one very long day in July, I counted over 2,000 individuals. Zooplankton tend to be more difficult to work with due to their small size, fragility, and large quantity.
A sample that looks quick and easy can turn into a never-ending search for the smallest of mysids. Most of the mysids that I have sorted can be as small as 5 mm in length. Being difficult to identify is an understatement. Figure 1 shows a sample in the beginning stages of analysis, with a wide range of mysids and other zooplankton. Different species of mysid shrimp generally have the same body shape, structure, size, eyes and everything else you can think of. The only way to easily tell them apart is by their telson, which is a unique structure of their tail. Their telsons cannot be seen with the naked eye and it can also be hard to find with a microscope if you do not know exactly what you are looking for.
Throughout my time identifying these tiny creatures I have found 9 different species of mysid from this gray whale foraging ecology project in Port Orford from the 2017 summer. But in 2018 three mysid species have been particularly abundant, Holmesimysis sculpta, Neomysis rayii, and Neomysis mercedis.
H. sculpta has a unique telson with about 18 lateral spines that stop as they reach the end of the telson (Figure 2). The end of the telson has 4 large spines that slightly curve to make a fork or scoop-like shape. From my own observations I have also noticed that H. sculpta has darker coloring throughout their bodies and are often heavily pregnant (or at least during the month of August). Neomysis rayii and Neomysis mercedis have been extremely difficult to identify and work with. While N. rayii can grow up to 65 mm, they can also often be the same small size as N. mercedis. The telsons of these two species are very similar, making them too similar to compare and differentiate. However, N. rayii can grow substantially bigger than N. mercedis, making the bigger shrimp easier to identify. Unfortunately, the small N. rayii still give birth to even smaller mysid babies, which can be confused as large N. mercedis. Identifying them in a timely manner is almost impossible. After a long discussion, we decided it would be easier to group these two species of Neomysis together and then sub-group by size. Our three categories were 1-10 mm, 11-15 mm, 16+ mm. According to the literature, N. mercedis are typically 11-15 mm meaning that anything over this size should be a N. rayii (McLaughlin 1980).
While mysids comprise the majority of our samples, they are not the only zooplankton that I see. Amphipods are often caught along with the shrimp. Gammarids look like the terrestrial potato bug and can grow larger than some species of mysid (Fig. 3).
As well as, Caprellidae (Fig. 4) that remind me of little tiny aliens as they have large claws compared to their body size, making it hard to get them out of our plankton net. These impressive creatures are surprisingly hardy and can withstand long times in the freezer or being poked with tweezers under a microscope without dying.
In 2017, there was a high abundance of amphipods found in both of our study sites, Mill Rocks and Tichenor Cove. Mill Rocks surprisingly had 4 times the number of amphipods than Tichenor Cove. This result could be one of the possible reasons gray whales were observed more in Mill Rocks last year. Mill Rocks also has a substantial amount of kelp, a popular place for mysid swarms and amphipods. The occurrence of mysids at each of these sites was almost equal, whereas amphipods were almost exclusively found at Mill Rocks. Mill Rocks also had a higher average number of organisms than Tichenor Cove per samples, potentially creating better feeding grounds for gray whales here in Port Orford.
Analyzing the 2018 data I can already see some differences between the two years. In 2018 the main species of mysid that we are finding in both sites are Neomysis sp. and Holmesimysis sculpta, whereas in 2017 Alienacanthomysis macropsis, a species of mysid identified by their long eye stalks and blunt telson, made up the majority of samples from Tichenor Cove. There has also been a large decrease in amphipods from both locations compared to last year. Two samples from Mill Rocks in 2017 had over 300 amphipods, however this year less than 100 have been counted in total. All these differences in zooplankton prey availability may influence whale behavior and movement patterns. Further data analysis aims to uncover this possibility.
The past 6 weeks working as part of the 2018 gray whale foraging ecology research team in Port Orford have been nothing short of amazing. We have seen over 50 whales, identified hundreds of zooplankton, and have spent almost every morning on the water in the kayak. An experience like this is a once in a lifetime opportunity that we were fortunate to be a part of. For the past few years, I have been creating videos to document important and exciting times in my life. I have put together a short video that highlights the amazing things we did every day in Port Orford, as well as the creatures that live just below the surface. I hope you enjoy our Gray Whale Foraging Ecology 2018 video with music by Myd – The Sun.

“BLOW!”, yells a team “Whale Storm” member, as mist remains above the water from an exhaling gray whale (Eschrichtius robustus). While based at the Port Orford Field Station for 6 weeks of my final summer as an undergrad at Oregon State University my heart has only grown fonder for marine wildlife. I am still in awe of this amazing opportunity of researching the foraging ecology of gray whales as a Marine Studies Initiative and GEMM Lab intern. From this field work I have already learned so much about gray whales and their zooplankton prey, and now it’s time to analyze the data we have collected and see what ecological stories we can uncover.
WORK IN THE FIELD
This internship is my first field work experience and I have learned many skills and demands needed to study marine wildlife: waking up before the sun (every day begins with screaming alarms), being engulfed by nature (Port Orford is a jaw-dropping location with rich biodiversity), packing up damp gear and equipment to only get my feet wet in the morning ocean waves again, and of course waiting on the weather to cooperate (fog, wind, swell). I wouldn’t want it any other way.
Whether it is standing above the ocean on the ‘Cliff Site’ or sitting in our two-man kayak, every day of this internship has been full of new learning experiences. Using various field work techniques, such as using a theodolite (surveying equipment to track whale location and behavior), Secchi disks (to measure water clarity), GoPro data collection, taking photos of wildlife, and many more tools, have given me a new bank of valuable skills that will stick with me into my future career.
To maximize my amazing internship experience, I am conducting a small data analysis project using the data we have collected these past weeks and in previous summers. There are so many questions that can be asked of these data, but I am particularly interested in how many times individual gray whales return to our study area to forage seasonally or annually, and if these individual whales forage preferentially where certain zooplankton prey are available.
After many hours of data collection in the field either in the kayak or on the cliff, we get to take a breather in the lab to work on various projects we are each assigned. Some job tasks include processing data, identifying zooplankton, and looking through the photos taken that day to potentially identify a known whale. Once photos are processed and saved onto the rugged laptop, they are ready for some serious one on one. Looking through each of the 300 photos captured each day can be very tedious, but it is worthwhile when a match is found. Within the photos of each individual whale I first determine whether it is the left or right side of the whale – if we are lucky we get both! – and maybe even a fluke (tail) photo!
The angles of these photos (Fig. 4 & 5) are very different, so it could be difficult to tell these are the same whale. But, have a closer look at the pigmentation patterns on this whale. Focus on a single spot or area of spots, and see how patterns line up. Does that match in the same area in the next photo? If yes, you could have yourself a match!
Buttons, one of the identified gray whales (Fig. 4 & 5), was seen in 2016, 17, and 18. I was so excited to identify Buttons for the 3rd year in a row as this result demonstrates this whale’s preference for foraging in Port Orford.
Zooplankton and whale foraging behavior
By using the theodolite we track the whale’s position from the cliff location. I have plugged these coordinates into Google Earth, and compared the coordinates to our zooplankton sample stations from that same day. These methods allow me to assess where the whale spent time, and where it did not, which I can then relate to the zooplankton species and abundance we caught in our sample tows (we use a net from the research kayak to collect samples throughout the water column).
‘Eyeball’ is one of our resident whales that we have identified regularly throughout this season here in Port Orford. I have compared the amount of time Eyeball has spent near zooplankton stations to the prey community we captured at each station.
There is a positive trend in the amount of time the whale spent in an area with the percent abundance of Holmesimysis sculpta (Fig. 7: blue trend line).
Conversely, there is an inverse trend with two other zooplankton species: Neomysis sp. (grey trend line) and Caprellidae (orange trend line). These results suggest that Eyeball has a foraging preference for areas where Holmesimysis sculpta (Fig. 6) is more abundant. Who would have known a whale could be so picky? Once the season comes to an end, I plan to use more of our data to continue to make discoveries about the foraging preferences of gray whales in Oregon.

In ecology, biodiversity is a term often touted for its key importance in stable ecosystems. Every organism plays its role in the constant struggle of nature, competing and cooperating with each other for survival. The sun provides the initial energy to primary producers, herbivores eat those producers, and predators then eat the consumers. The food chain is a simplistic way to look at how ecosystems work, and of course, it is more like an intricate web of interactions. Fungus and plants work together to trade nutrients and create a vast network of fertile soils; kelp forests provide habitats and food for a variety of prey that marine predators feed on. There are checks and balances between all these organisms that give breath into the beauty and color we see in ecosystems around the world. And, here in Port Orford is no exception. Coming to the project I expected to see some whales, of course. However only three weeks in and I’ve been absolutely astounded with the amount of marine biodiversity we’ve experienced. These past three weeks have been nothing if, well, wild.
Eschrichtius robustus, The Gray Whale
There was no doubt we would see gray whales, that is what we are here for after all, and studying them in the field has been an incredibly enlightening experience. Watching an animal every day for weeks really gets you into their head. You start to connect with them and think about their behaviors in different ways. You begin to realize that the individuals have unique quirks, habits and tendencies. For example, one whale would feed quickly for a time, and then seem to run out of energy and “log” itself, floating on the surface, taking multiple breaths in succession to recover before diving back down. Many whales come from the south, to feed in Mill Rocks before moving to Tichenor Cove, and then leave our study region through “Hell’s Gate” to the North, often resting a moment, taking multiple breaths and then launching into the open sea. Still, when you think you know these whales, they surprise you with an alarming unpredictability, making tracking them a new experience every day.
The whale in Fig. 1 surprised us, and honestly, being so close to it was as humbling as it was awesome. I expected to see whales, but never expected such a close encounter. These gentle giants are one of our not so distant relatives in the ocean. Many of us do this kind of research for more than just the science and the data. Many of us do it for the connection we feel to our mammal family.
Phoca vitulina richardii, The Pacific Harbor Seal
I absolutely adore these harbor seals! They’re well known for their friendliness towards humans as their dopey little heads pop up out of the water to greet you with a curious look in their eyes. They like to bob in the surf and stare at us while we’re out sampling in the kayak. At first, we got quite excited seeing one, often startling them as we’d squeal “seal!” to each other and they’d dip back under and scurry away. Now though, they seem more comfortable being around our kayak (Fig. 2).
One day a seal followed Lisa and Hayleigh around the jetty on their way back from sampling, swimming around the kayak and investigating them. Out in Mill Rocks, we often see them stretching on top of the rocks, seemingly doing a little yoga session while basking in the morning sun. Despite their cute and cuddly appearance, they are still predators. With plenty of fish to eat and make them happy, these harbor seals are quite plentiful themselves, and I’d like to think we’ve become quite good friends with the little guys.
Tursiops truncatus, The Bottlenose Dolphin
One morning we were in Mill Rocks and a large cloud of fog moved in, so we decided to wait it out before making our passage to Tichenor Cove. While sitting there, enjoying a snack, we noticed some dorsal fins popping up about 100 meters from us. Caught by surprise, Haley and I scrambled for our cameras and lo and behold, we noticed they were a small pod of dolphins! Two adults and a calf. Unfortunately, as you can see from our pictures, it is difficult to identify what species they were exactly.
After communicating with Lisa and Leigh, we have decided that their dorsal fins were far too big and curved to be harbor porpoises (Fig. 3), and the intersection of the head and rostrum seem to have the classic look of a bottlenose dolphin (Fig. 4).
If these were in fact bottlenose dolphins, why are they here in Port Orford, Oregon? It’s uncommon for them to be so far north in our colder waters. Were they foraging for food? Finding refuge from predators? Is it because our waters are becoming warmer? A sighting like this gives more weight to how climate change is affecting our oceans and how marine animals are responding by adapting their migratory and feeding behaviors.
Pisaster and Pycnopodia, The Common Sea Star and the Sunflower Star
One of the coolest aspects of living at the Port Orford Field Station is the fact that we have access to a lot of engagement with other scientists. For instance, we were able to attend a webinar about Sea Star Wasting Disease (SSWD) research currently happening at OSU by Post Doc Sarah Gravem. In a nutshell, a bacterial disease has been infecting sea stars along the west coast, causing a rapid plummet in their populations. Pisaster and Pycnopodia (Fig. 5) have been particularly affected. They are keystone predators, and as such, hold an important role in intertidal ecosystems. Feeding on snails, urchins, other sea stars and various mollusks, these sea stars maintain species populations and allow for a diverse and stable intertidal zone, which then supports many other near shore marine species. While SSWD’s cause is relatively unknown, Pisaster seems to be recovering while Pycnopodia is still struggling. I’ve even heard some anecdotal reports that fishermen here in Port Orford have noticed the lack of Pycnopodia as well, but they are rather pleased that these “ragmops” have stopped mucking up their lines and crab pots.
Below the Surface
There is a charm to the deep, a mystery and wonder that has captured the imagination of humans ad nauseam. Stories, movies, music and masterpieces of art have been inspired by The Abyss. Below the surface lies a diverse world teeming with life, full of questions and answers to be found. While marine mammals are why we’re here, there’s an entirely different environment under the water that is unseen from the safety of our dry, oxygen rich air. Our research doesn’t involve any diving, and so our eyes under the water are a GoPro camera attached to a downrigger on our kayak. Although designed to measure zooplankton community density, we’ve seen quite a bit more than itty bitty sea bugs in the depths of our little harbor here in Port Orford.
Strongylocentrotus purpuratus, The Purple Sea Urchin
Urchins are known for their bright colors and spiny ball like exterior. Close relatives to the sea stars, urchins inhabit the intertidal zones and also take residence within kelp beds. During our kayak training, we passed by some rocks near the cliffs and it was an awesome sight seeing the diversity of intertidal critters such as anemones, sea stars and sea urchins. However, a week into data collection, we have noticed something startling: a large quantity of the urchins cover the seafloor and the kelp, or at least what was left of the kelp (Fig. 6).
Sea urchins are important members in their communities. They graze on algae and control it from overwhelming the waters, but when left unchecked urchins can completely decimate kelp beds. This pattern is often referred to as “urchin barrens”. Sea otters and sea stars are the urchin’s main predator, and due to the absence of otters and the emergence of SSWD, the occurrence of urchin barrens has risen. An assessment of the reintroduction of the sea otters to Oregon by Dominique Kone, a GEMM Lab graduate student, is underway, and there is a lot of new research on SSWD, both of which could support the ‘ecosystem control’ of urchin populations. We’ve already spotted the urchins wreaking their havoc on the kelp in two separate sites in Tichenor Cove. Since gray whales primarily feed within these kelp beds, this increase in urchin populations is something that we are monitoring. An urchin barren can happen quickly and causes significant ecosystem damage, so this is not something to ignore. If we lose the kelp, it’s easy to imagine that we may lose the whales.
Alopias vulpinus, The Thresher Shark
By far, the most exciting thing I’ve seen so far has been this lovely creature (Fig. 7). The thresher shark usually inhabits the oceanic and coastal zones in tropical and temperate waters. They feed on pelagic schooling fish, squid and sometimes even shorebirds. They attack by whipping their tails (which grow to be the size of their body!) at their prey to stun them. Threshers are on the IUCN Red List of Threatened Species as “Vulnerable” due to their declining populations. They are often hunted for shark fin soup, or by trophy hunters due to their elegant and unique tails.
Haley, our resident shark enthusiast, was able to tell that this shark was a female by the lack of claspers (male appendages) on her pelvic fin. Why was she here though? During the summer, threshers will migrate to colder yet productive northern waters to feed, and on some rare occasions, such as this one, they will come closer to shore. Perhaps she was chasing prey into the harbor and found it to be full of yummy food, or she is a juvenile, which often stay near the continental shelf.
Either way, we were all surprised and excited to see such an exotic and beautiful species of shark caught on camera in our study zone. She even does a little strut in front of the GoPro camera, showing off her beautiful caudal fin!
Protecting our Wilds
These are only a few examples of the many different animals at work in Port Orford’s ecosystem. Perhaps the biodiversity here is why this is such a hot spot for our whale friends. The productive and lively waters have shown us so many critters, and likely many more we have yet to see. But alas, we have three more weeks of data collection and new discoveries, and I couldn’t be more excited.
“It is a curious situation that the sea, from which life first arose should now be threatened by the activities of one form of that life. But the sea, though changed in a sinister way, will continue to exist; the threat is rather to life itself.”
– Rachel Carson, The Sea Around Us
This experience only drives me further into my pursuit of ecological research. I believe it’s incredibly important to understand the world and how it functions, and to do so before it’s too late. All too often we have breakthrough discoveries in science because something has already fallen apart. Ecosystems are fragile, and climate change, pollution, and other anthropogenic disturbances all have an impact which damage and alter ecosystems and the services they provide. However, it’s an impact we can control with a fundamental understanding of how nature works. With a little hope, some integrity, and a whole lot of passion, I believe we have the power to truly make a difference.
By Hayleigh Middleton, GEMM Lab summer 2018 intern, entering OSU undergrad
Cold Fingers and Carabiners: that’s what most of the past three weeks have been about. We’ve progressively been getting up earlier—with many thanks to the coffee pot and multiple alarms— in order to be on the water collecting data before the wind and fog decide to kick in. Working on the ocean at 7 am with wet hands, metal equipment, a tight suit, and a “refreshing” breeze while trying to keep an eight-foot sit-on-top kayak from tipping over is challenging to say the least. Making sure the Theodolite is perfectly level on its tripod resting on sand-covered ground at the top of a cliff? Not much easier. The air is cold, the wind is cold, the equipment is cold, I’m cold, and now, everything is wet.
I absolutely love it.
Of all the ways I could have chosen to spend my summer before starting college at OSU, I’m so glad I took a chance and asked to spend it here. The official goals of our research project are to monitor and record the foraging habits of the Pacific Coast Feeding Group of gray whales, attempt to find out if specific individuals tend to have site fidelity and forage here year after year, and why or how they choose certain spots to feed over others. What does that mean for me? I get to kayak and take pictures of whales for six weeks! Of course, there’s a bunch of technical stuff and expensive equipment that took us two weeks to learn, but now we’re off to a great start and ready to learn more about these amazing creatures.
We have such a short amount of time to collect all this data to try and fill in the puzzle that is gray whale behavior, and we’re only a few weeks in, but I feel like I’ve already connected with this group of 60,000-pound mammals. That, in essence, is really what we’re doing here. We’re on top of a 33-meter-high cliff watching empty water for hours on the chance that we’ll be able to see a whale, identify it through photo-ID, track it with the theodolite to figure out its behavior, and use our kayak data to figure out its diet and feeding choices. Even though the whales forage up to two kilometers away from our tracking spot, it feels like they know we’re watching them. Sometimes it feels like they’re teasing us—we’ll see one, and once we get the sights fixed on it, it dives down and doesn’t come back up until we’ve turned our attention. One whale got into a very predictable pattern: three blows and then a deep dive, forage for five minutes, pop up half a viewfinder away, three more blows. We set our sights on the third blow and waited for her to resurface.
She swam away and didn’t show herself again.
Other times it’s like they conspire against us. Earlier this week, we spent most of the morning tracking the same whale. A couple hours into the track, another whale popped up right next to the first. Since we use a computerized tracking program, each whale is assigned a group number. That way, we can track each individual’s path and later match it to the photo identification database and sometimes a nickname. The two whales surfaced at just the right frequency and distance apart that deciding which number was currently up was guesswork for a good 15 minutes, but we gave them new track numbers and were able to sort it out later after reviewing our photos.
On another day, we surveyed for whales until quitting time, which is 3:00 pm. About 2:30 pm, one was finally spotted. I named her Princess because she couldn’t be bothered to bring her body out of the water enough so we could mark her location or take a picture except for when her pectoral fin, the tip of which was “gloved” in white, came out and made a motion like a princess in a parade. When there are whales around, we can’t just say “oh look, 3:00 pm time to go” because this is important data to collect. So, we decided to wait until 3:30 pm to see if she surfaced again within visual range. 3:30 pm came and still no sign of her, so I packed up the theodolite and tripod. As soon as the box was closed, she blew, and another whale surfaced right in front of the cliff. We got some pictures of the closer one for a bit and decided that was enough. As the camera was being lowered into its case, another whale surfaced in the cove. It felt like the first went and told all the whales heading south “hey, these guys want to leave at 3, so show up right around then.” That day we got back to the lab around 5. Even though this meant being on the cliff for almost 10 hours that day, it was thrilling to have seen so many whales in one day.
Then there are times when the whales seem to beg for attention. On our third day on the cliff, we saw what we believe to be a juvenile come swimming into view. We assume that he was a juvenile because he was “small” and quite blank in terms of pigmentation and scarring. He was adorable. He stayed over at Mill Rocks for a while foraging, all of which we “fixed” into the tracking program via the Theodolite, and then he came toward us into the little kelp patch just in front of our cliff site. He would dive down, scoop up some zooplankton to eat, and resurface right in the middle of the kelp. The cutest part is that he would then proceed to roll around in the kelp and further drape himself in it.
Having such a young whale come and forage made us wonder if mothers who have site fidelity then teach their young “hey, you don’t have to go all the way north, there’s a ton of good food here in Port Orford.” Hopefully that’s one of the things we’ll be able to figure out with the data collected with this long–term study. But in the meantime, I still have three weeks of data to collect and a bunch more whales to meet.

Did you know that Excel has a maximum number of rows? I do. During Winter Term for my GIS project, I was using Excel to merge oceanographic data, from a publicly-available data source website, and Excel continuously quit. Naturally, I assumed I had caused some sort of computer error. [As an aside, I’ve concluded that most problems related to technology are human error-based.] Therefore, I tried reformatting the data, restarting my computer, the program, etc. Nothing. Then, thanks to the magic of Google, I discovered that Excel allows no more than 1,048,576 rows by 16,384 columns. ONLY 1.05 million rows?! The oceanography data was more than 3 million rows—and that’s with me eliminating data points. This is what happens when we’re dealing with big data.
According to Merriam-Webster dictionary, big data is an accumulation of data that is too large and complex for processing by traditional database management tools (www.merriam-webster.com). However, there are journal articles, like this one from Forbes, that discuss the ongoing debate of how to define “big data”. According to the article, there are 12 major definitions; so, I’ll let you decide what you qualify as “big data”. Either way, I think that when Excel reaches its maximum row capacity, I’m working with big data.
Here’s the thing: the oceanography data that I referred to was just a snippet of my data. Technically, it’s not even MY data; it’s data I accessed from NOAA’s ERDDAP website that had been consistently observed for the time frame of my dolphin data points. You may recall my blog about maps and geospatial analysis that highlights some of the reasons these variables, such as temperature and salinity, are important. However, what I didn’t previously mention was that I spent weeks working on editing this NOAA data. My project on common bottlenose dolphins overlays environmental variables to better understand dolphin population health off of California. These variables should have similar spatiotemporal attributes as the dolphin data I’m working with, which has a time series beginning in the 1980s. Without taking out a calculator, I still know that equates to a lot of data. Great data: data that will let me answer interesting, pertinent questions. But, big data nonetheless.
This is a screenshot of what the oceanography data looked like when I downloaded it to Excel. This format repeats for nearly 3 million rows.
I showed this Excel spreadsheet to my GIS professor, and his response was something akin to “holy smokes”, with a few more expletives and a look of horror. It was not the sheer number of rows that shocked him; it was the data format. Nowadays, nearly everyone works with big data. It’s par for the course. However, the way data are formatted is the major split between what I’ll call “easy” data and “hard” data. The oceanography data could have been “easy” data. It could have had many variables listed in columns. Instead, this data alternated between rows with variable headings and columns with variable headings, for millions of cells. And, as described earlier, this is only one example of big data and its challenges.
Data does not always come in a form with text and numbers; sometimes it appears as media such as photographs, videos, and audio files. Big data just got a whole lot bigger. While working as a scientist at NOAA’s Southwest Fisheries Science Center, one project brought in over 80 terabytes of raw data per year. The project centered on the eastern north pacific gray whale population, and, more specifically, its migration. Scientists have observed the gray whale migration annually since 1994 from Piedras Blancas Light Station for the Northbound migration, and 2 out of every 5 years from Granite Canyon Field Station (GCFS) for the Southbound migration. One of my roles was to ground-truth software that would help transition from humans as observers to computer as observers. One avenue we assessed was to compare how well a computer “counted” whales compared to people. For this question, three infrared cameras at the GCFS recorded during the same time span that human observers were counting the migratory whales. Next, scientists, such as myself, would transfer those video files, upwards of 80 TB, from the hard drives to Synology boxes and to a different facility–miles away. Synology boxes store arrays of hard drives and that can be accessed remotely. To review, three locations with 80 TB of the same raw data. Once the data is saved in triplet, then I could run a computer program, to detect whale. In summary, three months of recorded infrared video files requires upwards of 240 TB before processing. This is big data.
In the GEMM Laboratory, we have so many sources of data that I did not bother trying to count. I’m entering my second year of the Ph.D. program and I already have a hard drive of data that I’ve backed up three different locations. It’s no longer a matter of “if” you work with big data, it’s “how”. How will you format the data? How will you store the data? How will you maintain back-ups of the data? How will you share this data with collaborators/funders/the public?
The wonderful aspect to big data is in the name: big and data. The scientific community can answer more, in-depth, challenging questions because of access to data and more of it. Data is often the limiting factor in what researchers can do because increased sample size allows more questions to be asked and greater confidence in results. That, and funding of course. It’s the reason why when you see GEMM Lab members in the field, we’re not only using drones to capture aerial images of whales, we’re taking fecal, biopsy, and phytoplankton samples. We’re recording the location, temperature, water conditions, wind conditions, cloud cover, date/time, water depth, and so much more. Because all of this data will help us and help other scientists answer critical questions. Thus, to my fellow scientists, I feel your pain and I applaud you, because I too know that the challenges that come with big data are worth it. And, to the non-scientists out there, hopefully this gives you some insight as to why we scientists ask for external hard drives as gifts.

This was the very first lecture slide in my population dynamics course at UC Davis. Population dynamics was infamous in our department for being an ultimate rite of passage due to its notoriously challenging curriculum. So, when Professor Lou Botsford pointed to his slide, all 120 of us Wildlife, Fish, and Conservation Biology majors, didn’t know how to react. Finally, he announced, “This [pointing to the slide] is all of you”. The class laughed. Lou smirked. Lou knew.
Lou knew that there is more truth to this meme than words could express. I can’t tell you how many times friends and acquaintances have asked me if I was going to be a park ranger. Incredibly, not all—or even most—wildlife biologists are park rangers. I’m sure that at one point, my parents had hoped I’d be holding a tiger cub as part of a conservation project—that has never happened. Society may think that all wildlife biologists want to walk in the footsteps of the famous Steven Irwin and say thinks like “Crikey!”—but I can’t remember the last time I uttered that exclamation with the exception of doing a Steve Irwin impression. Hollywood may think we hug trees—and, don’t get me wrong, I love a good tie-dyed shirt—but most of us believe in the principles of conservation and wise-use A.K.A. we know that some trees must be cut down to support our needs. Helicoptering into a remote location to dart and take samples from wild bear populations…HA. Good one. I tell myself this is what I do sometimes, and then the chopper crashes and I wake up from my dream. But, actually, a scientist staring at a computer with stacks of papers spread across every surface, is me and almost every wildlife biologist that I know.
There is an illusion that wildlife biologists are constantly in the field doing all the cool, science-y, outdoors-y things while being followed by a National Geographic photojournalist. Well, let me break it to you, we’re not. Yes, we do have some incredible opportunities. For example, I happen to know that one lab member (eh-hem, Todd), has gotten up close and personal with wild polar bear cubs in the Arctic, and that all of us have taken part in some work that is worthy of a cover image on NatGeo. We love that stuff. For many of us, it’s those few, memorable moments when we are out in the field, wearing pants that we haven’t washed in days, and we finally see our study species AND gather the necessary data, that the stars align. Those are the shining lights in a dark sea of papers, grant-writing, teaching, data management, data analysis, and coding. I’m not saying that we don’t find our desk work enjoyable; we jump for joy when our R script finally runs and we do a little dance when our paper is accepted and we definitely shed a tear of relief when funding comes through (or maybe that’s just me).
What I’m trying to get at is that we accepted our fates as the “scientists in front of computers surrounded by papers” long ago and we embrace it. It’s been almost five years since I was a senior in undergrad and saw this meme for the first time. Five years ago, I wanted to be that scientist surrounded by papers, because I knew that’s where the difference is made. Most people have heard the quote by Mahatma Gandhi, “Be the change that you wish to see in the world.” In my mind, it is that scientist combing through relevant, peer-reviewed scientific papers while writing a compelling and well-researched article, that has the potential to make positive changes. For me, that scientist at the desk is being the change that he/she wish to see in the world.
One of my favorite people to colloquially reference in the wildlife biology field is Milton Love, a research biologist at the University of California Santa Barbara, because he tells it how it is. In his oh-so-true-it-hurts website, he has a page titled, “So You Want To Be A Marine Biologist?” that highlights what he refers to as, “Three really, really bad reasons to want to be a marine biologist” and “Two really, really good reasons to want to be a marine biologist”. I HIGHLY suggest you read them verbatim on his site, whether you think you want to be a marine biologist or not because they’re downright hilarious. However, I will paraphrase if you just can’t be bothered to open up a new tab and go down a laugh-filled wormhole.
Really, Really Bad Reasons to Want to be a Marine Biologist:
To talk to dolphins. Hint: They don’t want to talk to you…and you probably like your face.
You like Jacques Cousteau. Hint: I like cheese…doesn’t mean I want to be cheese.
Hint: Lack thereof.
Really, Really Good Reasons to Want to be a Marine Biologist:
Work attire/attitude. Hint: Dress for the job you want finally translates to board shorts and tank tops.
You like it. *BINGO*
In summary, as wildlife or marine biologists we’ve taken a vow of poverty, and in doing so, we’ve committed ourselves to fulfilling lives with incredible experiences and being the change we wish to see in the world. To those of you who want to pursue a career in wildlife or marine biology—even after reading this—then do it. And to those who don’t, hopefully you have a better understanding of why wearing jeans is our version of “business formal”.
