New steps towards community engagement: introducing high schoolers to the field

By Florence Sullivan, MSc, GEMM Lab Research Assistant

This summer, I had the pleasure of returning to Port Orford to lead another field season of the GEMM Lab’s gray whale foraging ecology research project.  While our goal this summer was to continue gathering data on gray whale habitat use and zooplankton community structure in the Port Orford region, we added in a new and exciting community engagement component: We integrated local high school students into our research efforts in order to engage with the local community to promote interest in the OSU field station and the research taking place in their community. Frequent blog readers will have seen the posts written by this year’s interns (Maggie O’Rourke Liggett, Nathan Malamud, and Quince Nye) as they described how they became interns, their experience doing fieldwork, and some lessons they’ve learned from the project. I am very impressed with the hard work and effort that all three of them put into making this field season a success.  (Getting out of a warm bed, and showing up at the field station at 6am sharp for five weeks straight is no easy feat for high-schoolers or an undergrad student during summer break!)

During the month of August, our team collected the following data on whale distribution and behavior:

  •  Spent 108 hours on the cliff looking for whales
  • Spent 11 hours actively tracking whales with the theodolite
  • Collected 19 whale tracklines
  • Identified 15 individual whales using photo-ID – Two of those whales came back 3 times each, and one of them was a whale nick-named “Buttons” who we had tracked in 2016 as well.

We also collected data on zooplankton – gray whale prey – in the area:

  • Collected 134 GoPro videos of the water column at the 12 kayak sample sites
  • Did approximately 147 zooplankton net tows
  • Collected 64 samples for community analysis to see what species of zooplankton were present
  • Collected 115 samples for energetic analysis to determine how many calories can be derived from each zooplankton

Since I began this project in 2015, I have been privileged to work with some truly fantastic interns.  Each year, I learned new lessons about how to be an effective mentor, and how to communicate our research goals and project needs more clearly. This year was no exception, and I worked hard to bring some of the things I’ve learned into my project planning.  As the team can tell you, science communication, and the benefits of building good will and strong community relationships were heavily emphasized over the course of the internship.  Everyone was encouraged to use every opportunity to engage with the public, explain our work, and pass on new things they had learned.  Whenever the team encountered other kayakers out on the water, we took the time to share any cool zooplankton samples we gathered that day, and explain the goals of our research.  Maggie and I also took the opportunity to give a pair of evening lectures at Humbug Mountain State Park, which were both well attended by curious campers.

In addition, the team held a successful final community presentation on September 1 at the Port Orford Field Station that 45 people attended!  In the week leading up to the presentation, Quince and Nathan spent many long hours working diligently on the powerpoint presentation, while Maggie put together a video presentation of “the intern experience” (Click here for the video showcased on last week’s blog).  I am incredibly proud of Nathan and Quince, and the clear and confident manner in which they presented their experience to the audience who showed up to support them.  They easily fielded the following questions:

Q: “How do you tell the difference between a whale that is searching or foraging?”

A: When we look at the boundaries of our study site, a foraging whale consistently comes up to breathe in the same spot, while a searching whale covers a lot of distance going back and forth without leaving the general area.

Q: “How do we make sure that this program continues?”

A: Stay curious and support your students as they take on internships, support the field station as it seeks to provide resources, and if possible, donate to funds that raise money for research efforts.

When communicating science, it is important to results into context.  In addition to showcasing the possibilities of excellent research with positive community support, and just how much a trio of young people can grow over the course of 6 weeks, this summer has highlighted the value of long term monitoring studies, particularly when studying long-lived animals such as whales. We saw far fewer whales this summer than compared to the two previous years, and the whales spent much less time in the Port Orford area (Table 1). As a scientist, knowing where whales are not (absence data) is just as important as knowing where whales are (presence data), and these marked differences drive our hypotheses! What has changed in the system? What can explain the differences in whale behavior between years?  Does it have to do with food quality or availability?  (This is why we have been gathering all those zooplankton samples.) Does it have to do with other oceanographic factors or human activities?

Table 1. Summary of whale tracking efforts for the three seasons of field work in Port Orford.   Notice how in 2017 we only collected 194 whale location points (theodolite marks). This is about 92% less than in the previous years.

2015 2016 2017
Hours spent watching 72:49 148:30 108
Hours spent tracking 80:39* 82:30 11
Number of individuals 43 50 15
Number of theodolite marks 2483 2414 194

*we often tracked more than one individual simultaneously in 2015

Long term monitoring projects give us a chance to notice differences between years, and ask questions about what are normal fluctuations in the system, and what are abnormal. On top of that, projects like this create the opportunity for additional internships, and to mentor more students in the scientific method of investigation.  There is so much still to be explored in the Port Orford ecosystem, and I truly hope this program is able to continue.  If you are interested in making a monetary contribution to sustain this research and internship program, donations can be accepted here (gemm lab fund) and here (field station fund).

The passion of a researcher

By Quince Nye, GEMM Lab Summer Intern, Pacific High School Junior

I have spent a lot of my life surrounded by nature. I like to backpack, bike, dive, and kayak in these natural environments. I also have the luck of having parents who are always planning to take me on another adventure where I get to see nature and its inhabitants in ways most people don’t get to enjoy.

Through my backyard explorations, I have begun to realize that Port Orford has an amazing ecosystem in the coves and rivers that are very tied into our community. I’ve fished and swam in these rivers, gone on kayaking tours in these coves (with a great kayak company called South Coast Tours that we partner with), and I’ve seen the life that dwells in them.

Nathan and Maggie paddle out to Mill Rocks for early morning sample collection

Growing up in a school of less than 100 kids I have learned to never reject an opportunity to be a part of something bigger and learn from that experience. So when one of my close friends told me about an OSU project (a college I’m interested in attending) that needed interns to help collect data on gray whales, and kayak almost every day, I signed up without a doubt in my mind.

The team gets some good practice tracking Buttons (Whale #3).  Left to right; Quince, Nathan, Maggie, Florence.

Fast forward a month, and I wake up at 5:20 am. I eat breakfast and get to the Port Orford Field Station. We make a plan for the operations of both the kayak team and cliff team. Today, I’m part of the cliff team, so I head up above the station to Fort Point. Florence and I set up the theodolite and computer at the lookout point and start taking half hour watch shifts searching the horizon for the spout of a gray whale.  Sometimes you see one right away, but other times it feels like the whales are actively hiding from you. These are the times I wish Maggie was here with her endless supply of Disney soundtracks to help pass the hours.

Imitating a ship’s captain, Quince points toward our whale while shouting “Mark”.

A whale spouts out at Mill Rocks and starts heading across to the jetty. Hurray, its data collection time! I try to quickly move the cross-hairs of the theodolite onto the position of the whale using a set of knobs like those on an etch-a-sketch. As you may understand, it’s not an easy task at first but I manage to do it because I’ve been practicing for three weeks. I say “Mark!” cueing Florence to click a button in the program Pythagoras on the computer to record the whale’s position.

The left hand side of Buttons – notice the scatter of white markings on the upper back.

Meanwhile, Florence sees that the whale has two white spots where the fluke meets the knuckles. Those are identifying marks of the beloved whale, Buttons. This whale has been seen here since 2016 and is a fan favorite for our on-going research program. Florence gets just as excited every time and texts her eagerly awaiting interns of previous years all about the sighting. Of course Buttons is not the only whale to have identifying marks such as scars and pigmentation marks. This is why we make sure to get photos of the whales we spot, allowing us to do photo-ID analysis on them through comparison to our database of pictures from previous years.

Quince practices CPR protocol on a training mannequin on his first day.

So far I have gained skill after skill in this internship. I got CPR certified, took a kayak training class, learned how to use a theodolite, and have spent many educational (and frustrating) hours entering data in Excel. I joined the program because I was interested in all of these things. It surprised me that I was developing a relationship with the whales I’m researching. By the end of August I’m now sure that I will also know many of the whales by name. I will probably be much better at using an etch-a-sketch, and I will have had my first taste at what being a scientist is like. What I strive for, however, is to have the same look in my eyes that appears in Florence’s whenever a familiar whale decides to browse our kelp beds.

Curiosity and Community, new ways of exploring our environment.

By Nathan Malamud, GEMM Lab summer intern, Pacific High School senior

I am someone who has lived in a small town for all his life. Pretty much everyone knows each other by their first name and my graduating class only has around 20 people. Everywhere you look you will find a farm, ranch, or cranberry bog (even our school has two bogs of their own!). Because of my small town life, I have a strong sense of community. However, I have also developed a curiosity about natural and global phenomena. I try to connect these two virtues by participating in scientific efforts that help my community. When I heard that the OSU Port Orford Field Station was offering internships, I knew right away that it would definitely be a great experience for me.

The view from our field site at Fort Point in Port Orford

Port Orford, on Oregon’s southern coast, is a town that is closely tied to the ocean. So naturally, it’s important to understand and monitor our surroundings so that our town can thrive. Last year, my Marine Science class helped me further understand the complexity of the ocean. Our first semester taught us all about marine biology, zoology, and ecology. Our second semester immersed us into oceanography, ocean geology, and ocean chemistry. During the second semester, we also took trips to our town’s marine science center and to the marine reserve near Rocky Point. I loved this course and decided to try to expand my knowledge about the subject by going to the OSU Field Station.

Our safety instructor teaches takes us through basic paddling techniques

As an intern, I am currently working with three teammates to understand the feeding behavior of gray whales – what places they like to eat zooplankton the most and why they like to eat there. This whale project helps our community by Port Orford enabling high school students to perform college-level scientific research and inquiry, as well as allowing us to learn valuable skills such as CPR, surveying using a theodolite, working with chemicals in a lab, and data processing.

We had to learn how to rescue ourselves just in case we have an accident in the boat.
We all made it back in the boat!

This internship with OSU’s GEMM Lab has taught me many new skills and given me new experiences that I have never had before. Before this internship, I had never been in a kayak. Now, I go out on the water nearly every other day! When on the water, I always try to sharpen my navigating skills. I use a GPS to pinpoint the locations of our sampling stations, and I communicate to my partner where we need to go and how we will get there.

Its very important to stretch before kayaking every morning.

Once we are there, it is my job to keep the boat close to the station location so that my partner can get accurate samples. This part is a very tricky task, because not only do I have to pay attention to the GPS to make sure we are within 10 meters of the spot, but I also have to pay attention to my surroundings. I have to look at the ocean, and figure out what direction the waves are coming from. I have to watch how external forces, like wind and currents, can cause the boat to drift far from station, and I have to correct drifting with gentle paddle strokes. This is hard, especially since the kayak is so light and easy to get pushed around by the wind. However, despite the difficulty, I have learned that it is crucial not to panic. Frustration only makes things worse. The key is to maintain a harmonic balance of concentration and zen.

I have also learned that when collecting data in the field, it’s important to observe and document as much as possible. When we are in the kayak, we have 12 stations that we try to visit every day (as long as the weather cooperates). At each station, we first use a secchi disk to test the water clarity, then lower the GoPro to film the water column and see where the zooplankton are. Sometimes we catch other interesting things on the video too, such as siphonophores (my personal favorites are jellies and salps) and rockfish.

A rockfish captured with our GoPro.

Next we tow a zooplankton net through the water, and let it collect zooplankton of all shapes and sizes, from tiny mysids to skeleton shrimp. Then we proceed to the next station and repeat the process. We have to remember to label everything, and tell the GoPro camera what station we’re at so we can sort all the information correctly when we get back to the field station. At the end of the day, we log our data into a computer, and preserve half our plankton samples with ethanol, so that we can identify the species present.  The other half gets frozen for caloric content analysis by our collaborator Dr. Kim Bernard to help us understand how much zooplankton a whale needs to eat to meet its energy needs each day.

By repeating this entire process every day, we are able to look at daily changes, which also helps us to better understand why whales spend time in certain areas and not others. Be sure to check out my teammate Maggie’s blog post about some of the tools and technologies we use to track the whales!

This whale project has been, and definitely still is, a great experience for me! I have learned a lot and have worked with some amazing people. I believe that I am learning many valuable skills, and that the skills I learn will allow me to help my community.

A Little Slice of Heaven

Guest writer: Maggie O’Rourke-Liggett, GEMM Lab summer intern, Oregon State University,

One of the biggest obstacles an undergraduate can face is fulfilling the degree requirement of completing an internship or research opportunity. With almost every university and degree program requiring it for graduation and many employers requiring prior experience, the amount of pressure and competition is intense.

After being rejected from the internships I applied for earlier in the year, I heard about Dr. Leigh Torres’s research with the Geospatial Ecology of Marine Megafauna (GEMM) Lab . I decided to email her and ask if she had any open positions. Fast-forward a few weeks and I am collaborating with Florence Sullivan, a recent masters graduate from OSU, on the logistics of my Gray Whale Foraging Behavior internship with the GEMM Lab.

During my time with the GEMM Lab team, I have been assisting with photo identification analysis of gray whales (Eschrichtius robustus), using a theodolite and Pythagoras computer program to track their movements, collecting samples of the zooplankton they eat, and recording other oceanographic data with our time-depth recorder. This project is hoping to identify the drivers of gray whale fine-scale foraging behavior.  For instance: Why do gray whales spend more time in some areas than others?  Does the type or density of prey affect their behavior? Do the whales use static features like kelp beds to help find their food? As a senior currently studying oceanography, who desires to study whale behavior in the future, this internship is like finding a gold mine.

Ever since day one at Hatfield Marine Science Center, I’ve been working with people who share the same passions for marine mammals as me. Spending hours upon hours sorting thousands of pictures may seem like a painful, tedious job, but knowing my work helps others to update existing identification catalogs makes it worthwhile. Plus, who wouldn’t want to look at whales all day?! After a while, you start to recognize specific individuals based on their various pigment configurations and scars. Once you can recognize individuals, it makes the sorting go by faster and helps with recognizing individual whales in the wild faster. It’s always exciting to sort through the photos and observe from the cliff or kayak and recognize a whale from the photo identification work.

After Florence taught me how to set up and operate the theodolite, a survey tool used to track a whale’s movements, we taught a class to undergrads on how to use it. I’ll never get over how people’s faces lit up when we discussed how the instrument works and its role in the overall mission.

These past two weeks at OSU’s Port Orford Field Station have been like living on a little slice of heaven. My days are filled with clear views of the coast and the sound of waves crashing serve as a backdrop on my home for the month, the bed-and-breakfast turned field station. Each morning, the sun fills my room as I gather my gear for the day and help my teammates load the truck. We spend long days on the water collecting zooplankton samples and GoPro video or on the cliff recording whale behavior through the theodolite. To anyone searching for an internship and feeling burnt out from completing application after application, don’t give up. You’ll find your slice of heaven too.

Making a Splash

By: Cathryn Wood, Lawrence University ’17, summer REU in the GEMM Lab

Greetings from Port Orford! My name is Cathryn, and I am the fourth member of the GEMM Lab’s gray whale foraging ecology research team, which includes Florence, Kelli, and the other Catherine (don’t worry, I go by Cat). Nearly 5 weeks into field season, I am still completely amazed with my first West Coast experience and doing what I’ve always dreamt of: studying marine mammals. Coming from Michigan’s Upper Peninsula, this may seem slightly out of place, but my mom can attest; she read “Baby Beluga” to me every night when I was a toddler. Now a rising senior majoring in biology at Lawrence University, I’ve been focusing my coursework on aquatic and marine ecology to prepare for graduate school where I plan to specialize in marine science. Being part of this research is a very significant step for me into the field.

So how did I end up here, as part of this amazing project and dream, women-in-science team? I am interning through OSU’s Ocean Sciences REU program at the Hatfield Marine Science Center, where the GEMM Lab is located. REU stands for “Research Experience for Undergraduates ”, and is an NSF-funded research internship program found in numerous universities around the country. These internships allow undergrads to conduct independent research projects under the guidance of a faculty mentor at the program’s institution. I applied to several REUs this past winter, and was one of 12 undergrads accepted for the program at HMSC. Each of us is paired with different faculty members to work on various projects that cover a diverse range of topics in the marine sciences; everything from estuarine ecology, to bioacoustics. I was ecstatic to learn that I had been paired with Dr. Torres as my faculty mentor to work on Florence’s gray whale project, which had been my first choice during the application process.

My particular research this summer is going to complement Florence’s master’s thesis work by asking new questions regarding the foraging data. While her project focuses on the behavioral states of foraging whales, I will be looking at the whale tracks to see if there are patterns in their foraging behavior found at the individual level. Traditionally, ecological studies have accepted classical niche theory, treating all individuals within a population as ecological equivalents with the same niche width. Any variances present among individuals are often disregarded as having an insignificant consequence on the population dynamics as a whole, but this simplification can overlook the true complexity of that population . The presence of niche variation among conspecifics is known to occur in at least 93 species across a diverse array of taxa, so the concept of individual specialization, and how it can affect ecological processes is gaining recognition progressively in the field (Bolnick et al., 2003). My goal is to determine whether or not the gray whales in this study, and presumably others in the Pacific Coast Feeding Group (PCFG), exhibit individual specialization in their foraging strategies . There are many ways in which individuals can specialize in foraging, but I will be specifically determining if fine scale spatial patterns in the location of foraging bouts exists, regardless of time.

To address my question, I am using the whale tracking data from both 2015 and 2016, and learning to use some very important software in the spatial ecology world along the way through a method that Dr. Torres introduced to me. Starting in ArcGIS, I generate a kernel density layer of a raw track (Fig. 1 ), which describes the relative distribution of where the tracked whale spent time (Fig. 2 ). Next, using the isopleth function in the software Geospatial Modelling Environment, I generate a 50% density contour line that distinguishes where the whale spent at least 50% of its time during the track (Fig. 3 ). Under the assumption that foraging took place in these high density areas, we use these 50% contour lines to describe foraging bout locations. I now go back to ArcGIS to make centroids within each 50% line, which mark the exact foraging bout locations (Fig. 4 ).

Fig. 4 Final centroids to signify foraging bouts
Fig. 4 Final centroids to signify foraging bouts

These centroids will be determined for every track by an individual whale, and then compared relative to foraging locations of all tracked whales to determine if the individual is foraging in different locations than the population. Then, the tracks of individuals who repeatedly visit the site at least three times will be compared with one another to determine if the repeat whales show spatial and/or temporal patterns in their foraging bout locations, and if specialization at a fine scale is occurring in this population. If you did not quite follow all those methods, no worries, it was a lot for me to take in at first too. I’ve finally gotten the hang of it though, and am grateful to now have these skills going into grad school.

Because I am interested in behavioral ecology and the concept of individuality in animal populations, I am extremely excited to see how this research plays out. Results could be very eye-opening into the fine scale foraging specialization of the PCFG sub-population because they already demonstrate diet specialization on mysid (as opposed to their counterparts in the Bering Sea who feed on benthic organisms) and large scale individual residency patterns along the Pacific Northwest (Newell, 2009; Calambokidis et al., 2012). Most significantly, understanding how individuals vary in their feeding strategies could have very important implications for future conservation measures for the whales, especially during this crucial foraging season where they replenish their energy reserves.  Management efforts geared for an “average population” of gray whales could ultimately be ineffective if in fact individuals vary from one another in their foraging strategies. Taking into account the ways in which variation occurs amongst individuals is therefore crucial knowledge for successful conservation approaches.

My project is unique from those of the other REUs because I am simultaneously in the midst of assisting in field season number two of Florence’s project. While most of the other interns are back at Hatfield spending their days in the lab and doing data analyses like a 9-5 job, I am with the team down in Port Orford for field season. This means we’re out doing research every dawn as weather allows. Though I may never have an early bird bone in my body, the sleepy mornings are totally worth it because ecology field work is my favorite part of research. To read more about our methods in the field, check out Florence’s post.

Since Catherine’s last update, we’ve had an eventful week. To our dismay, Downrigger Debacle 2.0 occurred. (To read about the first one, see Kelli’s post). This time it was not the line – our new line has been great. It was a little wire that connected the downrigger line to the pipe that the GoPro and TDR are connected to. It somehow snapped due to what I presume was stress from the currents.   Again, it was Catherine and I in the kayak, with a very successful morning on the water coming to a close when it happened. Again, I was in the bow, and she was in the stern deploying the equipment – very déjà vu. When she reeled in an equipment-less line, we at first didn’t know how to break it to Florence and Kelli who were up on the cliff that day. Eventually, Catherine radioed “Brace yourselves…” and we told them the bad news. Once again, they both were very level-headed, methodical, and un-blaming in the moments to follow. We put together the same rescue dive team as last time, and less than a week later, they set off on the mission using the GPS coordinates I had marked while in the kayak. Apparently, between the dredging taking place in the harbor and the phytoplankton bloom, visibility was only about 2 feet during the dive, but they still recovered the equipment, with nothing but baked goods and profuse thanks as payment. We are very grateful for another successful recovery, and are confident that our new attachment mechanism for the downrigger will not require a third rescue mission (Fig. 6-8). Losing the equipment twice now has taught us some very important things about field work. For one, no matter how sound you assume your equipment to be, it is necessary to inspect it for weak points frequently – especially when salt water and currents are in the picture. Perhaps even more importantly, we’ve gotten to practice our problem solving skills and see firsthand how necessary it is to act efficiently and calmly when something goes wrong. In ecological field research you have to be prepared for  anything.

In other news, unlike our slow-whale days during the first two weeks of the project, we have recently had whales to track nearly every day from the cliff! In fact, the same, small, most likely juvenile, whale pictured in Catherine’s last post has returned several times, and we’ve nicknamed her “Buttons” due to two distinguishing white spots on her tail peduncle near the fluke. Though we tend to refer to Buttons as “her”, we cannot actually tell what the sex is definitively…until now. Remember in Catherine’s post when she described how Buttons defecated a lot, and how our team if, given the opportunity, is supposed to collect the feces when we’re out in the kayak for Leila’s project?  Everything from hormone levels to reproductive status to, yes, sex, is held in that poop! Well, Miss (or Mr.) Buttons was in Tichenor Cove today, and to our delight, she performed well in the defecation department once again. Florence and I were on cliff duty tracking her and Kelli and Catherine were in Tichenor on the kayak when we first noticed the defecation.  I then radioed down to the kayak team to stop what they were doing and paddle quickly to go collect it before it sank (Fig. 9).  Even in these situations, it is important to stay beyond 100 yards of the animal, as required by the MMPA. Florence and I cheered them on and our ladies did indeed get the poop sample, without disturbing the whale (Fig. 10). It was a sight to behold.

We were able to track Buttons for the remainder of our time on the cliff, and were extremely content with the day’s work as we packed all the gear up later in the afternoon. Right before we were about to leave, however, Buttons had one more big treat for us. As we looked to the harbor before starting the trek back to the truck, we paused briefly after noticing a large, white splash in the middle of the harbor, not far from the dock. We paused for a second and thought “No, it can’t be, was that —?” and then we see it again and unanimously yelled “BREACH!” Buttons breached about five times on her way back to Tichenor Cove from where she had been foraging in Mill Rocks. It is rare to see a gray whale breach, so this was really special. Florence managed to capture one of the breaches on video:

At first I thought a big ole humpback had arrived, but nope, it was our Buttons! I am in awe of this little whale, and am forever-grateful to be in the presence of these kinds of moments. She’s definitely made her splash here in Port Orford. I think our team has started to as well.

Dredging and low visibility doesn’t stop us! We paddle on.

By: Catherine Lo, Research Intern, Oregon State University ‘16

Hello everyone! My name is Catherine Lo and I am a recent graduate from Oregon State University with a Bachelor’s of Science in Biology with a focus in Marine Biology. It has been an incredible whirlwind leading up to this point: long nights studying for finals, completing my degree, and planning the next steps for my future. I am fortunate to be working as a summer research intern for the GEMM Lab under the supervision of Dr. Leigh Torres and Msc. student Florence Sullivan in their research on the foraging ecology of gray whales. I have dreamed of working with marine mammals, potentially as a research veterinarian and so, capturing this position has been a great opportunity to begin my career.

The days go slow, but the weeks go fast. It’s already week 4 of our field season and the team and I are definitely in the groove of our research. The alarm(s) goes off at 5:00 AM…okay maybe closer to 5:30 AM (oops!), getting dressed for either the kayak or cliff based work, scarfing down breakfast that is usually a diet consisting of toast and peanut butter, and then heading off to the beach to launch the kayak. But this week it was different. A dredging event in Port Orford coordinated by the US Army Corps of Engineers is now taking place right next to the port’s jetty near our study site (Figure 1). This is an important process to move the sediment built up during the year in order for ships to safely navigate in and out of the port. We knew this was going to happen at some point over the summer, and worried that it might impact our research methods and objectives, but at the same time it offers some new opportunities: the chance to see how our GoPro and mysid sampling methods in Tichenor Cove are impacted by the sediment flow from the dredging activities.

Figure 1. View of the dredger from the cliff field site in Port Orford.

My teammate Kelli and I were stationed on the cliff during the first deposit of sediment after the dredge’s first night and morning’s worth of scooping sand. None of us knew where the actual deposit site would be so we kept a good eye on it. The ship headed past the jetty. Turned around and, as a concerned feeling mustered within our field team, it began lowering the platform holding the sand just 250 yards away from our primary study site in Tichenor Cove! At this point, we knew things were going to be different in our samples. Unfortunately along with the sediment stirring up from dredging, we think a phytoplankton bloom is occurring simultaneously. Our GoPro footage lately has been rather clouded making it difficult to identify any mysid relative to our past footage. You can compare Figure 2 to the GoPro image found in Figure 2 of a previous post. It is times like these that we learn how dynamic the ocean is, how human activity can alter the ocean ecosystem, and how to adapt to changes, whether these adaptations are within our reach or not. We are interested to see how our sample sites will change again over time as the dredging operation finishes and the phytoplankton bloom ends.

Figure 2. This GoPro image taken in Tichenor Cove illustrates exactly how murky our view of the water column is with the sediment dredging operation in close proximity.

Aside from the current water clarity situation, we’ve also had some exciting moments! Given how few whales we’ve seen thus far and how the ones we have tracked are predominately hanging by Mill Rocks, which is ~1km east of Tichenor Cove, Dr. Leigh Torres—our head advisor—thought it would be a good idea to check out the mysid scene over there to see what the attraction was. So, we sent our kayak team over there to conduct a few GoPro drops and zooplankton net tows and figure out what is so enticing for the whales.

While conducting this sampling work at Mill Rocks, I and my teammate were lucky enough to encounter a gray whale foraging. And believe me, we were going “off-the-walls” as soon as we heard from the cliff team and saw a blow as the whale surfaced nearby. It was one of those “best time of my life” moments where my dreams of kayaking this close to a whale came true. We fumbled around for our waterproof camera to get clear shots of its lateral flanks for photo identification while also trying to contain our excitement to a more decent level, and at the same time we had to make sure we were not in the whale’s path. There it was; surface after surface, we admired the immense size and beauty of a wild animal before our eyes. The worst part of it was when our camera battery died not long after taking a few pictures, but in a way it gave us a chance to really appreciate the existence of these animals. Note to self during research: always check your batteries are fully charged before heading out!

It baffles me how so often people walk along beaches or drive by without knowing an animal as incredible as this whale is just outside of the shoreline. Every time I’m inside pulling out time stamps or doing photo identification, I always think, “I wonder if there’s a whale in Tichenor Cove or at Mill Rocks right now…Yeah, there probably is one”. Alas, the data management work needs to be done and there’s always the next day for an opportunity of a sighting.

For a few days, our kayak team wasn’t able to work due to a small craft advisory. If you’ve ever been to Port Orford, you’d understand the severity of how windy it gets here. Ranging between 15 knots to 25 knots as early as 7am, so it gets rather difficult to maintain position at each of our sampling stations in our kayak. Fortunately our cliff team was able to set out. We were lucky to see a small whale foraging inside Tichenor Cove and later move onto Mill Rocks. This little one was giving us quite a show! Almost every time it came to the surface, defecation was observed shortly after. As unpleasant as feces might be, it can actually provide an abundance of information about a specific whale including sex, reproductive status, hormone levels, and much more. While doing our research, we are always keeping an eye out for signs of defecation in order to collect samples for another lab member’s PhD work. Here you can check out more information about Leila’s research. Figure 3 depicts a great image of defecation captured by our cliff team.

In addition to helping out Leila’s work, we recently began a collaboration with Aaron Galloway from The Oregon Institute of Marine Biology (OIMB). Aaron and his post-doc are looking at the fatty acid composition of mysid as an approach to eventually infer the diet of an aquatic animal. Check out his website which is linked to his name to learn more about the basis of his approach! While we collect mysid samples for them, in return they give us substantial information about the energy content of the mysid. This information on the energetic content of mysid will help the GEMM Lab answer questions about how much mysid gray whales need to eat.

Oregon State University and University of Oregon have a long-standing, intense rivalry. However, as an Alumna from Oregon State, I am amazed and thrilled to see how these two institutions can come together and collaborate. I mean, we’re all here for the same thing. Science, right? It creates the opportunity to apply integrative research by taking advantage of various expertise and resources. If we have those chances to reach out to others, why not make the most of it? In the end, sound science is what really matters, not rooting for the ducks or beavers.

My marine science background is based on my experiences looking at tidepools and hopping around on rocks to understand how vast intertidal communities range from invertebrates to algae. These experiences were an incredible part of my life, but now I look at the ocean unsure of what animals or environmental situations I might encounter. That’s what makes it so attractive. Don’t get me wrong. The intertidal will always hold a special place in my heart, but the endless possibilities of being a part of this marine mammal research team is priceless. I have learned so much about myself including my strengths and weaknesses. Living in Port Orford, which is a small coastal town with just a little over 1,000 people gives you a new perspective. The community has been very welcoming and I have appreciated how so much interest is placed on the kind of work we do. As I eat my nightly bowl of ice cream, I think about how, from here on out, the good and the bad can only bring a lifetime of skills and memories.

From the highs to the lows, that’s just how it blows!


By: Kelli Iddings, MSc Student, Duke University, Nicholas School of the Environment

The excitement is palpable as I wait in anticipation. But finally, “Blow!” I shout as I notice the lingering spray of seawater expelled from a gray whale as it surfaces to breathe. The team and I scurry about the field site taking our places and getting ready to track the whale’s movements. “Gray whale- Traveling- Group 1- Mark!” I exclaim mustering enough self-control to ignore the urge to drop everything and stand in complete awe of what in my mind is nothing short of a miracle. I’ve spotted a gray whale searching and foraging for food! As a student of the Master of Environmental Management program at Duke University, I am collaborating on a project in Port Orford, Oregon where my team and I are working to gain a better understanding of the interactions between the Pacific Coast Feeding Group (PCFG) gray whales and their prey. Check out this blog post written earlier by my teammate Florence to learn more about the methods of the project and what motivated us to take a closer look at the foraging behavior of this species.

Understanding the dynamics of gray whale foraging within ecosystems where they are feeding is essential to paint a more comprehensive picture of gray whale health and ecology—often with the intent to protect and conserve them. A lot of our recent effort has been focused on developing and testing methods that will allow us to answer the questions that we are asking. For example, what species of prey are the PCFG whales feeding on in Port Orford? Based on the results of a previous study (Newell and Cowles 2006) that was conducted in Depoe Bay, Oregon, and a lot of great knowledge from the local fisheries and the Port Orford community, we hypothesized that the whales were feeding on a small, shrimp-like crustacean in the order Mysida. Given the results of our videos, and the abundance of mysid, it looks like we are right (Fig. 1)!

Figure 1: Mysids, only 5-25mm in length, collected in Tichenor Cove using a downrigger to lower a weighted plankton net into the water column from our kayak.
Mysids are not typically the primary food source of gray whales. In their feeding grounds in the Bering and Chukchi Seas near Alaska, the whales feed on benthic amphipods on the ocean floor by sucking up sediment and water and pushing it through baleen plates that trap the food as the water and sediment is filtered out. However, gray whales demonstrate flexible feeding strategies and are considered opportunistic feeders, meaning they are not obligate feeders on one prey item like krill-dependent blue whales. In Oregon, mysid congregate in dense swarms by the billions, which we hypothesize, makes it energetically worthwhile for the massive 13-15m gray whales to hang around and feed! Figure 2 illustrates a mysid swarm of this kind in Tichenor Cove.

Figure 2: Image captured using a Hero 4 Black GoPro. Rocky Substrate is visible in lower portion of image and a clear swarm of mysid is aggregated around this area.

Once we know what the gray whales are eating, and why, we ask follow up questions like how is the distribution of mysid changing across space and time, if at all? Are there patterns? If so, are the patterns influencing the feeding behavior and movement of the whales? For the most part, we are having success characterizing the relative abundances of mysid. No conclusions can be made yet, but there are a few trends that we are noticing. For instance, it seems that the mysid are, as we hypothesized, very dense and abundant around the rocky shoreline where there are kelp beds. Could these characteristics be predictors of critical habitat that whales seek as foraging grounds? Is it the presence of kelp that mysid prefer? Or maybe it’s the rocky substrate itself? Distance to shore? Time and data analysis will tell. We have also noticed that mysid seem to prefer to hang out closer to the bottom of the water column. Last, but certainly not least, we are already noticing differences in the sizes and life stages of the mysid over the short span of one week at our research site! We are excited to explore these patterns further.

The biggest thing we’re learning out here, however, is the absolute necessity for patience, ingenuity, adaptability, and perseverance in science. You heard that right, as with most things, I am learning more from our failures, than I am from our successes.  For starters, understanding mysid abundance and distribution is great in and of itself, but we cannot draw any conclusions about how those factors are affecting whales if the whales don’t come! We were very fortunate to see whales while training on our instruments in Newport, north of our current study site. We saw whales foraging, whales searching, mother/calf pairs, and even whales breaching! Since we’ve been in Port Orford, we have seen only three whales, thrown in among the long hours of womanpower (#WomenInScience) we have been putting in! We are now learning the realities of ecological science that >gasp< fieldwork can be boring! Nevertheless, we trust that the whales will hear our calls (Yes, our literal whale calls. Like I said, it can get boring up on the cliff) and head on over to give the cliff team in Port Orford some great data—and excitement!

Then, there is the technology. Oh, the joys of technology. You see I’ve never considered myself a “techie.” Honestly, I didn’t even know what a hard drive was until some embarrassing time in the not-so-distant past. And now, here I am working on a project that is using novel, technology rich approaches to study what I am most passionate about. Oh, the irony. Alas, I have been putting on my big girl britches, saddling up, and taking the whale by the fluke. Days are spent syncing a GoPro, Time-Depth Recorder (TDR), GPS, associated software, and our trusty rugged laptop, all the while navigating across multiple hard drives, transferring and organizing massive amounts of data, reviewing and editing video footage, and trouble shooting all of it when something, inevitably, crashes, gets lost, or some other form of small tragedy associated with data management. Sounds fun, right? Nonetheless, within the chaos and despair, I realize that technology is my friend, not my foe. Technology allows us to collect more data than ever before, giving us the ability to see trends that we could not have seen otherwise, and expending much less physical effort doing so. Additionally, technology offers many alternatives to other invasive and potentially destructive methods of data collection. The truth is if you’re not technologically savvy in science these days, you can expect to fall behind. I am grateful to have an incredible team of support and such an exciting project to soften the blow. Below (Fig. 3) is a picture of myself embracing my new friend technology.

Figure 3: Retrieving the GoPro, and some tag-a-long kelp, from the water after a successful deployment in Tichenor Cove.

Last but not least, there are those moments that can best be explained by the Norwegian sentiment “Uff da!” I was introduced to the expression while dining at The Crazy Norwegian, known famously for having the best fish and chips along the entire west coast and located dangerously close to the field station. The expression dates back to the 19th century, and is used readily to concisely convey feelings of surprise, astonishment, exhaustion, and sometimes dismay. This past week, the team was witness to all of these feelings at once as our GoPro, TDR, and data fell swiftly to the bottom of the 42-degree waters of Tichenor cove after the line snapped during deployment. Uff da!!! With our dive contact out of town, red tape limiting our options, the holiday weekend looming ahead, and the dreadful thought of losing our equipment on a very tight budget, the team banded together to draft a plan. And what a beautiful plan it was! The communities of Port Orford, Oregon State University, and the University of Oregon’s Institute of Marine Biology came together in a successful attempt to retrieve the equipment. We offer much gratitude to Greg Ryder, our retrieval boat operator, OSU dive safety operator Kevin Buch, and our divers, Aaron Galloway and Taylor Eaton! After lying on the bottom of the cove for almost three days, the divers retrieved our equipment within 20 minutes of the dive – thanks to the quick and mindful action of our kayak team to mark a waypoint on the GPS at the time of the equipment loss. Please enjoy this shot (Fig. 4) of Aaron and Taylor surfacing with the gear as much as we do!

The moral of the story is that science isn’t easy, but it’s worth it. It takes hard work, long hours, frustration, commitment, collaboration, and preparedness. But moments come along when your team sits around a dining room table, exhausted from waking and paddling at 5 am that morning, and continues to drive forward. You creatively brainstorm, running on the fumes of the passion and love for the ocean and creatures within it that brought everyone together in the first place; each person growing in his or her own right. Questions are answered, conclusions are drawn, and you go to bed at the end of it all with a smile on your face, anxiously anticipating the little miracles that the next day’s light will bring.

We need all the “Kelp” we can get!

Hello from Hatfield Marine Science Center! This is Justin bringing you the latest and greatest in Gray Whale news. But first, let me fill you folks in with some info about me.  I am an undergraduate student, transitioning into my senior year, with Oregon State University’s Fisheries and Wildlife Department. In addition to my major, I am also minoring in statistics; crazy right? I have hopes and dreams of working in Marine Ecology, and I believe working on this Gray Whale project is a fine start! Which means, this summer, I have had the fortunate opportunity to work alongside the lovely Florence van Tulder, the mastermind behind the project, as well as Cricket and Sarah, the other two charismatic interns.

Our team name is derived from the scientific name of the gray whale: E. robustus, and the colorful "buff" scarves you can see us wearing on most days.

As we were wrapping up our two week stint in Port Orford, We observed the Gray Whales exhibiting some interesting behavior; they seemed to move from kelp patch to kelp patch, almost as if they were searching for something. What could be hiding under the luscious stands of Nereocystis luetkeana, otherwise known as bull kelp? Well, with the presence of defecation ( whale droppings) left behind from diving whales near many of the floating kelp patches, one culprit came to mind- mysid shrimp. Mysid shrimp are believed to be a primary prey source of the Gray whales.

Naturally, my curiosity got the best me and I ended up spending hours on end conducting literature searches and looking for bathymetry maps, thanks to Florence. All joking aside, I asked Florence if we could use our fancy Theodolite to assess or roughly map the distribution of the kelp patches. We would create polygonal shapes of the kelp on a map and observe how the whales move with respect to the kelp. The idea being, to get a better of picture of the relationship between the whales and the kelp, if any relationship exists at all. It is still a work in progress, due to our survey sites getting all kinds of “fogged” up. When the kinks are worked out and we have some useful visual data, we will post an awesome photo.

Port Orford didn’t just bring us sweet whales, it brought the heat! Temperatures were up to almost the nineties the last week in July! We beat the heat with plenty of hydration and sun block and the predicable wind patterns became a savior on those sweltering days giving us temporary relief.  The heat seemed to tease out other critters as well. We saw a variety of birds, from turkey vultures, Peregrine Falcons, Ospreys, Bald Eagles, and even Egrets!  In the water we saw baby Harbor seals, and some bonus River Otters.

This is our "tripod" of river otters!

In more recent news, August 8th marked our first full month of surveying between our two whale hotspots. However, the term “hotspot” doesn’t always seem to be fitting. This past week has been a tough one for the team and I up in Boiler Bay due to less than optimal weather conditions and our survey site has been exposed to an abnormal cycle of fog. Our friendly “neighborhood” grays have been a bit sparse, and yet, we have had Humpback Whales grace us with their presence and these whales have been spotted during several survey days this week! ( In the tradition of opportunistic data, we even tracked one of them.)

This summer has been very fun because not only do we get to watch whales every day, but when we are in Boiler Bay, we have the opportunity to meet fascinating people from all over the world! The positive support for the project coming from the community is quite a nice touch to our days in the field. If you are ever in the neighborhood, stop by and say hello, maybe share a whale’s tale or two!

Gray Whale Goofs

Hello there!  Florence here, signing in from Newport.  We had a fantastic trip south to Port Orford, and tracked another 53 whales bringing our season total up to 117 so far! This morning, we were back out at Boiler Bay and spent 5 hours staring at empty water – in keeping with the theme of this post, field work does not always go as planned.

Our two study areas couldn’t be more different.  At the Boiler Bay State Wayside, we are approximately 18 meters off the water.  In Port Orford, we are perched on the side of a 63 meter tall cliff. This extra height greatly increases our range and accuracy as well as changing the angle of our photography and the type of photo analysis we can do.  We’re quite excited to have a top down view of our whales, because the photos we are capturing will allow us to use certain photogrammetry techniques to measure the length and girth of the individuals.  With luck, when we compare the photos from the beginning of the season (now) to the end of our study (September) we may be able to see a change in the height of the post-cranial fat deposit, which would indicate a successful foraging season.  Gray whales do not eat from the beginning of their southward migration, through the breeding and calving season, until they reach productive foraging grounds at the end of their northward migration.  This means that all their sustenance for 6+ months is derived from their summer foraging success.  Did you know that they even generate their own water through an oxidation reaction which creates ‘metabolic water’ from their blubber stores?  So it will be rather fantastic if we manage to measure the change in whale body condition over the course of the summer – particularly if we are able to spot any mother-calf pairs who will have had an especially grueling journey north.

So, while our photo database is advancing nicely, technical difficulties are to be expected when you’re in the field, and sometimes, troubleshooting takes longer than you would like it to.  This evening, let me introduce you to the elusive species known as ‘the Chinese land whale.’  It is a very rare breed which spontaneously generates itself from misaligned computer files.

When the theodolite beeps as we ‘mark’ a whale, a pair of horizontal and vertical angles are getting sent from the machine to a program called ‘Pythagoras’ on the laptop. Given our starting coordinates and a few other variables, the program auto-calculates for us the latitude and longitude of that whale.  While we hoped it would be a simple matter to upload these coordinates to Google Earth to visualize the tracklines, it turns out that Pythagoras stores the East/West hemisphere information in a separate column, so if we just plot the raw numbers, our whale tracks end up in the middle of a field in rural China! Hence, the rare ‘Chinese land whale’.  Now that we know the trick, it is not so difficult to fix, but we were quite surprised the first time it happened!

If you dont have your hemisphere correctly labeled, you end up in China instead of Oregon.
If you don’t have your hemisphere correctly labeled, you end up in China instead of Oregon.

Of course, that is not the only thing that has gone wrong with visualizing the tracklines.  When we first got to Graveyard Point survey site, it turns out that we had set our azimuth (our reference angle) the wrong direction from true north, so all our whales seemed to be foraging near the fish and chips restaurant in the middle of town.

If the azimuth is incorrectly referenced, you might end up on land instead of in the water.
If the azimuth is incorrectly referenced, you might end up on land instead of in the water.

After discovering that in order to rotate something 180degrees, you simply need to alter the azimuth angle by 90degrees, (we’re still not sure why this is working), the whales left the fish and chips to us and returned to the harbor.  Anyways, now that we’ve figured out these glitches, we can focus on identifying individual whales, and figuring out which track-lines might be repeat visitors.

Once all the kinks got worked out - the real trackline!  Dont worry, whale 60 did not go through the jetty, thats an artifact of the program wanting to draw straight lines from point a to b.  more likely we simply missed a surface as it transited around the point of the jetty.

In other outreach news, the OSU media department came out to the field and interviewed us a few weeks ago (on a day that the theodolite and computer were refusing to talk to each other due to a faulty connector cable – which is always delightful when one is trying to showcase research in progress). The resulting article has been posted should you wish to take a look:
