Accurate and Precise: Learning how to track a focal species

By Jonah Lewis, rising junior at Pacific High School, GEMM Lab Intern 2023

Hello, I’m Jonah Lewis, the other high school intern for the TOPAZ/JASPER Project. I am a rising junior for Pacific High School in Port Orford. I am interested in many things, including computer sciences, electrical sciences, different types of engineering, and lately, marine biology. At the end of February, my biology teacher, Hilary Johnson, was looking for high schoolers to join this internship and I decided that it could be a great experience for me. I applied, and somewhere in March, before I knew it, I was being interviewed by Allison Dawn, our Zoop Troop Sergeant, and Leigh Torres, the head of the operation. I was so nervous for my interview, and tried my best to do well. Then on March 31st, I saw the job offer email, and my family and I were overjoyed. Now that we are in our fourth week, I can say the people and the experiences have been amazing, but my favorite part of all has been the cliff site and the adrenaline rush of tracking a whale moving across the ocean.

Figure 1: Jonah smiles after fixing a whale using the theodolite. 

Theodolite is an important aspect of this research project. This instrument was invented by Leonard Digges back in the 1550’s and is a highly accurate instrument for mapping, engineering, etc. Read here to learn more about the theodolite’s component parts, written by last year’s intern Nichola Gregory, a previous JASPER intern. In Port Orford, we use it for tracking where a gray whale blows and surfaces! Setting up the theodolite can be a challenge for newcomers, but as you repeatedly put this device together, and then take it down, you understand and can troubleshoot better and faster than the previous time. It took me and the team some practice to be able to get all three ways it needs to level just right, or else the instrument decides to throw a fit. For example, when the theodolite isn’t exactly leveled right, or maybe the batteries are low, or the cord just isn’t plugged in all the way, it will just beep at you, trying to say there is an error. After the theodolite is properly leveled, you connect it to the computer that runs our software program called Pythagoras.

Not only does the physical setup require care, but “fixing” a whale requires technique. Here, we are trained to be both accurate and precise when following our focal species. To be accurate, we would need to position the theodolite scope so that the whale is close to the crosshairs. To be precise, we need to fix the whale in the same location on the theodolite crosshairs consistently. Our team has learned how to be both accurate and precise.

Figure 2: Accurate and precise diagram using the crosshairs of a theodolite as reference, diagram by A. Dawn.

Being on cliff team can get tedious, even when you are not using the theodolite to fix a whale. Staring at the waves and the horizon can feel like an eternity, especially when gray whales aren’t active in our study area. Yet, during this time we have to be “on effort”. Being on effort is making sure you scan the horizon consistently, both you and a partner are constantly looking at our study sites. All this is best represented by our team manager Allison: On the cliff with her, she is always looking at the ocean, paying attention to both sites, and for at least the first hour or longer, she will not sit down.

After we collect all of our data from kayak and cliff each day, we head down to the dry lab and get prepared to download and transfer our data to a hard drive known as “Tharp”. I learned that Marie Tharp was a woman in the 20th century, who mapped the ocean floors, which helps scientists even now. (The GEMM Lab names each hard drive after famous scientists; it helps to track the many hard drives.) When I use the hard drive, I think about her and about how I also helped collect data for mapping features in our marine study site. During the first week of data collection, Allison and I looked through the theodolite scope, found obvious kelp patches on the surface of the water, and fixed many times around the edges, making a complete polygon around the kelp beds.

This internship for the past four weeks has been an amazing experience. In addition to our fieldwork, I’ve been able to participate and connect with many other interns and professionals here at the Field Station. I have also enjoyed connecting with visitors from all different areas who come by and ask what research we’re doing on the cliff.  At the field station I have fun hanging with the guys at the house as well, where we play sports in our downtime and cook together. I also learn about what projects they are doing, from urchin culling to sea otter research, it all fascinates me. I have helped POSS (Port Orford Sustainable Seafood) with bagging fish, washing dishes, and in return they provide samples of the amazing food they make. I am overjoyed about what I have learned and the people I have met during this experience, and am so thankful to be a part of the ninth year of this project.

Diving into new experiences

By Natalee Webster, Oregon State University rising senior, GEMM Lab Intern 2023

When I was younger, I was terrified of the water, sobbing on a rock across the river, afraid to be immersed in the unknown. Flash-forward to the present and I have one more year left to finish my undergraduate degree in Biology at Oregon State University with a focus in Marine Biology. I was a little hesitant about choosing a more focused degree since I wasn’t sure what aspect of sciences piqued my interest more. However my curiosity for the ocean grew as I took the PADI Open Water scuba class through school. After earning my certification, I discovered I loved being in the water, and seeing the habitats I read about firsthand. I quickly took my Advanced Scuba and worked my way up to Divemaster, and ultimately AAUS Scientific diving. This new certification provided me with skills for a career in marine biology, performing tasks and taking surveys underwater. Through the diving community at OSU, I met Allison Dawn, our graduate student leader of the TOPAZ/JASPER project studying gray whale foraging ecology. Through meeting her I was informed about this project and decided to apply. Now, as I write, we are working on week three of this project, and I could not be happier with my decision. This internship has already taught me so much about the hard work and logistics that goes into studying the behaviors of large marine mammals in the field, as well as what it is like to closely work with a team to accomplish our goals.

Figure 1. Port of Port Orford at dawn.

Each morning we wake up before the sun with a new set of goals, with a variety of tasks ahead that certainly keeps you on your toes. Long-time readers will know of our kayak and cliff methods, but another aspect of this project is our CamDo underwater cameras. These are cameras that we place in Mill Rocks and Tichenor Cove, our two sampling sites, for a week at a time for longer term footage. In order to deploy these cameras we utilize scuba equipment to properly place them in a location. When the week is up, we go to recover the cameras to gather the data, replace SD card and batteries, and reset them for another week of underwater video footage. 

Although CamDo deployment is not a required part of this internship, I have been able to use my scientific diving certification to assist this project on the dives. I appreciate the opportunity to take apply skills to assist the project from a different perspective. Before my first week here I had never dove off the Oregon coast from a boat, so this task was daunting, as I was still getting to know everyone around the field station, and get a sense of my environment.

Figure 2. Photo of Natalee geared up for a dive in Mill Rocks. 

Our very first dive at Mill Rocks was intimidating but exciting. Allison and I got up before dawn to prepare the cameras and get to the dive boat the Black Pearl. Allison is our dive tender, handling equipment and logistics, and we worked alongside two other divers — Caroline Rice, an intern with ORKA here at the Port Orford field station, and Kevin Buch, our dive leader and the dive safety officer and scientific diving professor at OSU. Once we rolled off the boat and started our descent I began to feel more in my element as the green waters surrounded us. As we continued further and further to the ocean floor, I realized that visibility was turning from a green you could see rays of sunlight through, into a dark black — barely visible further than five inches from my face. We were able to position the camera lander as needed, but we could not secure the camera because of those black-out conditions. While I waited in the waters for direction on the dive, I put my face as close to the rock as the tides would let me and I saw a purple urchin underwater for the first time, and let me tell you, in the dark waters it was eerie. We finally surfaced and got on the boat to venture off to Tichenor Cove in an attempt to deploy the other CAMDO. Here, I realized that despite the best preparation, scientists need to remain adaptable and determined in the face of challenging ocean conditions.  

Figure 3. A screenshot of CAMDO footage showing fish swimming in the water column.

As we prepared for the next dive and began our descent, I silently wondered what I had gotten myself into. I hoped that not all dives off the Oregon Coast were as dark. While slowly descending into Tichenor Cove, I was pleasantly surprised to see that the waters were beautiful in contrast to the darkness of Mill Rocks. Tichenor seemed to be a safe haven in comparison to Mill Rocks; rather than the strong current pushing me along the rocks and urchins, I was able to calmly swim through the rocks and look at the many sea stars, nudibranch, anemones, and different hues of purple urchins living along them. 

Figure 4. Photos taken from GoPro of Tichenor Cove environment, showing rockfish, urchins, and an anemone. 

More recently, we recovered the camera for data processing. While comparing the footage between the two locations, I have learned the ocean is incredibly variable. From clear blue waters where you can clearly see juvenile and adult fish swimming in the water column, compared to nothing but murky brown and black waters. This variability inspired me to think more deeply about what the gray whales see while they forage for food. Dr. Leigh Torres visited our team and I was able to discuss our dives and inquire about the methods these whales use in order to eat. My basic knowledge of whale anatomy tells me that they have eyes; however, I was curious if they used eyesight to locate zooplankton and other food. Leigh informed me that these whales have whiskers! This was an exciting discovery for me, I googled it later and found that gray whales and many other baleen whales have hair follicles, called vibrissae (watch this NOAA video to learn more!), around their rostrum and mouth they use as tactile sensors. Leigh Torres has hypothesized a “sense-of-scale” that illustrates an interchange of sensory modalities such as vision, audition, chemoreception, magnetoreception and somatosensory perception that allows whales to track and capture of prey (Torres 2017). Research in this sensory field continues to grow to better understand how marine mammals  capture and track prey at various scales.

Figure 5. Image of a gray whale, the spot markings along its jaw and rostrum are hair follicles known as vibrissae. (2016)

Seeing these small segments of their habitat myself while underwater has given me much more respect for how these gray whales are able to forage in such a challenging and changing environment. My teammate Autumn is currently working on quantifying the zooplankton abundance recorded in the footage taken through CAMDO, so stay tuned on the Port Orford blogs to hear more about their project!

The opportunity to participate in this year’s Gray Whale Foraging Ecology project is something I will not take for granted and will appreciate greatly for years. It has given me the opportunity to grow my knowledge about the marine environment that I have been fascinated with, as well as given me skills and training in methods of field research. I  even got to apply my hard-earned underwater skills and conduct my first official scientific dives! I have been able to interact with the long-time locals of Port Orford, whether it be a fisherman sharing their orca encounter tales to retired photographers that chase the whales along the shore. The field station houses many projects focusing on different aspects of the Oregon coast from sea urchins and kelp to river otters along the shores and to outreach programs within the community. When everyone is settling back into the field station after their long day of work, it is great to be gathered in the kitchen and hear about the progress we’ve made and the experiences we’ve had. I look forward to the remaining three weeks I have in Port Orford with this community and my team! Wish us luck as we prepare to deploy the next round of CamDo cameras next week.

How to be a Zooper Trooper: Getting Comfy with the Uncomfortable

By Aly Covey, Marshfield High School student, GEMM Lab Intern 2023

Hello, everyone! My name is Aly Covey and I am a rising senior, one of two high school interns part of the  TOPAZ/JASPER project this summer. I have the pleasure of introducing the team name for this year. We came up with our name not too long after meeting each other last week, when our team member Autumn started calling the zooplankton samples we collected  “zoop soup”, which then led us to call our team the “zoop troop” (because it rhymes!). We had some other contenders for names, but none of them felt just right. I think this is because Zoop Troop has begun to mean more to us than just the convenient rhyme. We’ve all heard the phrase “being a trooper”, which describes someone who overcomes their struggles and we certainly have embodied that in each task, where we have demonstrated resilience in the face of specific challenges and pushing forward despite discomfort both mentally and physically.

Figure 1: Logo for this year’s team name, created by Autumn Lee.

As a team, we have bonded over this quality of resiliency, and quickly became close during our first week. We go on routine sunset beach walks where we look at interesting sand fleas, baby shrimp, and bring back pocket-fulls of shells and beach glass. As well as our group meals that always lead to fun conversation and a warm, family, feel. Personally, I have enjoyed getting to know everyone on the team and seeing their unique skills. Since the first day, Jonah has constantly been trying to help cook and clean for Zoop Troop whenever he can. Natalee and I have bonded over our daily need to find time for a quick cat nap. We usually find Autumn working on her individual research project in the kitchen. And of course, Allison has earned the name of “Whale Mom” because of her dedication to taking care of the team’s needs outside of the daily training and being the best mentor to all of us. 

Over the last two weeks of training, I learned all the new technology and protocols the team needs to successfully use the gear for our research. Allison has been such a huge help teaching us the in’s and out’s of everything while still letting us make mistakes and allowing us to learn from them. So far, I feel confident in all the things I have learned. That said, I still wonder what it will feel like out in the field without a supervisor helping when something goes wrong. Allison has given us a few “non-data collecting” days to feel out the scene without her there and so far I, and whoever I’m working with that day, seem to be feeling fairly satisfied in our skill level, and it has been a nice opportunity to help each other when needed. 

Figure 2: Team prepping CamDo for deployment underwater

For me, it has been uncomfortable allowing myself to fail at certain tasks and having to restart from the beginning to get it right the next time. Patience is such an important skill needed for the work we do everyday. It’s very exciting to feel myself slowly start enjoying the idea of “trial and error” as I lean into all the new information we have absorbed these past few weeks. 

Although it is frustrating at times, I believe the team does a great job of creating a fun environment for each other while still being able to slow down and take in all the small details needed for each new task Allison teaches us. This experience has shown me that in order to persevere, you need to get comfortable with the uncomfortable.

Figure 3: Aly and Natalee learning kayak sampling skills

While completing tasks on my own, I am vigilant to catch errors and run over each protocol in my head multiple times before going out into the field. For example, our theodolite is a very important but delicate piece of equipment we use on the cliff to track and fix on the whales we see out in the water. It is incredibly tedious to set up Theota (our nickname for the theodolite) in a sufficient amount of time without messing up the leveling, cords, or measuring needed to properly run the program. During training, we get up to the cliff around 8am and are able to take as much time as we need to correctly level, connect the telescope to the computer, and reach each fix point without feeling rushed. However, during a “real” workday, we are up on the cliff as early as 6am, held to a standard of having all our gear fully charged and ready to go for the day, as well as being able to efficiently set everything up and ready to watch the whales and be the safety watch for kayak team. The first few times I put up Theota, I got very annoyed with having trouble leveling out everything, but after my 4th or 5th set up, I was feeling very confident in my ability and also being able to quickly move from one place to another to fix on something out in the water. 

Figure 3:  Aly fixing on a whale through the theodolite  

Like cliff site tasks, on-the-water protocols call for adaptability when things get rough; and the kayak is, in my opinion, more rigorous in protocol requirements, with much more room for error than the cliff work. This is likely because of the many types of gear we use while sampling from the kayak: we conduct visibility measurements, RBR Concerto and GoPro deployments, zooplankton net sampling — all while navigating in tricky ocean conditions. During our training, Allison took us out in the morning and taught us each how to properly navigate with the GPS and use all the sampling equipment like a pro. While it was a nice opportunity to double check everything with her, I knew going out without her wouldn’t be so easy. My first morning without Allison’s support, I had to redo multiple stations but was able to correct myself and learn from my mistakes. 

It is incredibly tiresome, but so rewarding to go out in the field early in the morning and come back to the lab in the afternoon with a tote full of new zooplankton samples or pictures of high-quality whale flukes to show everyone. The protocols in the lab are extensive, but the team has done a great job of taking tasks into their own hands and finishing processing data on their own accord.

Figure 4:  Zoop Troop on a beach walk 

So far, this internship has been an incredible opportunity for me, not just in my career but also in my personal life. I have learned so much from my team, everyone staying in the field station, and all the amazing people that I’ve had the pleasure to meet in the community. It has been so intriguing to learn about another small town in my home state of Oregon and compare all the similarities and differences from my home, Coos Bay. I’m so excited for what is to come in these next 4 weeks of research and for the team to keep you all informed. Having another summer to learn about the Pacific Ocean and solidify my love for marine life is such an endearing opportunity and I’m very grateful. I’m most excited for the first day I am able to complete all 12 sampling stations with ease. I believe my skills will continue to improve and I don’t expect any day to be dull working on this project. 

Zoop Troop team member, Aly, signing off!

Updates from the 2023 Port Orford Gray Whale Foraging Ecology Project (team name TBD!)

Allison Dawn, Master’s student, OSU Department of Fisheries, Wildlife and Conservation Sciences, Geospatial Ecology of Marine Megafauna Lab

Greetings from the South Coast Outpost, aka the Port Orford Field Station! Long-time GEMM lab blog readers will know that by this time of the year, our TOPAZ and JASPER projects are fully underway. We have officially entered our 9th consecutive year of these two integrated projects, which provides experiential learning internships to high school and undergraduate students while conducting long-term monitoring of gray whale foraging ecology in our small study region.

Much like last year, the Port Orford Field Station is at full capacity, with our team of five plus six other NSF REU, MSI, and Sea Grant interns. The research efforts here span a wide-range of subjects, including the long-standing ORKA kelp-urchin monitoring projects, river otter predation, science communication initiatives with the Redfish Rocks Marine Reserve, and more. This diversity in subject matter makes for excellent discussion during our communal dinners, and keeps the field station’s labs bustling with a variety of samples, gear, and equipment being transported in-and-out on a daily basis. Needless to say, it is a thriving environment for young scientists who are passionate about the community and ecosystems of the southern Oregon Coast. 

This is my third year participating in the project, and my second time as the solo graduate team leader. After having defended my master’s thesis this past June, I have been so excited to return to this incredible study site and share what I have learned about the system here with a new group of interns. I will write about my thesis work in a separate blog soon, but for now, I’d like to introduce you to the excellent group of motivated students that are on the team this year!

Figure 1: Autumn draws a pyramid while learning the equation for estimating zooplankton patch density, as provided in Hermanson, 2019.

First up, we have Autumn Lee.  Autumn is one of the GEMM Lab’s three REU students and together we are diligently working to automate the detection of zooplankton and predator occurrence from our in situ underwater cameras using the program VIAME. We hope to describe the predator-prey dynamics in Port Orford and a new, calculated metric for zooplankton patch density. Autumn moved to Mount Holyoke College, MA after celebrating their high school graduation with a drive-through commencement in Spring 2020. Despite the challenging start to undergrad due to COVID, Autumn is now a rising senior with a major in Neuroscience and Behavior with a certificate in Coastal Marine Sciences. Initially Autumn wanted to be a neurosurgeon or do veterinary medicine, but has always loved the ocean. After taking a few marine science classes back home, they decided to apply for our REU project in hopes of gaining their first marine science fieldwork experience. Autumn is excited to connect with like-minded students, the community, and volunteer with Port Orford Sustainable Seafood with the goal of consuming as much fresh, local seafood as possible in these six weeks.

Figure 2: Natalee beams after having captured two separate whales on camera for the first time.

Next on our team is Natalee Webster! Natalee is originally from St. Helens, OR and has her associates degree from Portland Community College. Natalee was on a nursing track but slowly accumulated environmental and marine biology classes that led her to obtain her first SCUBA diving certification. After this, she was hooked and decided to major in biology with a focus in marine biology. Now, Natalee has earned both her dive master and AAUS scientific dive certifications, and has already helped us deploy our underwater in situ cameras. Like Autumn, Natalee is excited to get involved with the community, meet other interns, and get her first scientific fieldwork experience. In addition to her water sport skills, she is already quite a natural at taking photos from the cliff site.

Figure 3: Aly enjoying a sunny morning on the cliff site with our high-powered binoculars.

Aly is a rising senior at Marshfield High School in Coos Bay, Oregon where her favorite subject is science. In particular, her favorite class is AP environmental where she first learned how to read dissolved oxygen graphs and was fascinated by how this metric can describe water quality for public health considerations. As of now, Aly is considering several colleges, including Oregon State University, with aspirations to major in marine science. Interestingly enough, she used to be afraid of the water. Despite this fear, and being the intrepid person she is, Aly taught herself how to surf during COVID and has since found a new-found respect for the ocean — so much so that she is now ready to make marine conservation her career. Aly is excited for our kayak training session next week and is ready to get in the water to start collecting zooplankton samples. Aly has had a consistently positive attitude during training week, even when learning the most tedious tasks, and can always make our team laugh. 

Figure 4: Jonah poses near Port Orford Sustainable Seafood while listening to the Junket audio tour of the town. 

Jonah is a junior at Pacific High School here in Port Orford where his favorite classes are math and woodshop, and he also loves to get involved in sports such as track and field, soccer, and basketball. As a freshman, Jonah took a 3-D printing class which affirmed his desire to learn more engineering techniques. While considering a summer job, Jonah was excited to watch our recruitment presentation and learn that he could use specialized equipment for marine science applications. He is now considering Oregon State University and Oregon Institute of Technology for his undergraduate career. Jonah has been a quick learner with excellent attention to detail, and is also an excellent cook — which myself and the others are grateful for. He is excited to spend more time on the cliff and wants to perfect his theodolite techniques to track whale movements.

Figure 5: First team photo! We were all very excited and grateful to have been greeted by two whales on our first day together.

In just this first week, we have deployed underwater cameras, tracked multiple whales in one day from the cliff, obtained Basic Life Safety/CPR certifications, and practiced kayak sampling methods from the dock. Next week, we have our kayak safety training, and will have many more days of practicing the cliff and kayak methods before we jump into official data sampling days. I know the team is just as excited as I am for the rest of the season, especially because of this increase in whale activity. It is heartening to see so many whales after our low occurrence year in 2021. Stay tuned for more updates, including what we decide for this year’s team name!

Whale Filled Summer in the GEMM Lab

By Cristy Milliken, Thomas More University, GEMM Lab REU Intern


It’s summertime in the GEMM Lab, meaning many visiting students, interns, and technicians working in the lab (12 additional people to be precise!). This influx of new faces in the lab means blog posts by some new people, including me, Cristy Milliken, as I am an NSF REU intern. I am a rising junior at Thomas More University where I am majoring in Biology along with obtaining a double minor in marine biology and environmental science. Prior to this internship I knew little about humpback whales aside from them being baleen whales and large mammals. Safe to say, I know much more about humpbacks after researching them for the SLATE project. SLATE stands for Scar-based Long-term Assessment of Trends in whale Entanglements. The project utilizes photos of humpback whales that have been collected from 2005 to 2023 to develop and refine methods of analyzing scaring rates. These methods of scar analysis will be used to determine the effectiveness of fishing regulations in Oregon. The SLATE project started recently (February 2023) and thus the current stage of the project is focused on analyzing many individual photographs of humpback whales captured in Oregon waters to determine the presence or absence of an entanglement scar.

Finding evidence of a scar on a whale is tricky, and we have encountered a few issues while developing our methodology.  There is no universal method to analyze the scarring rate in whales, yet we are building off the methods created and utilized by Annabelle Wall and Jooke Robbins (Wall et al., 2019; Robbins., 2012). Robbins first developed the method of scar analysis using images of humpback whales in the Gulf of Maine. Wall refined the methods by creating set categories that classified every sighting of each  individual to determine the likelihood of being entangled in the past. The image scoring methods have some flaws, and the descriptions can be vague, leaving more questions than answers. One specific issue we faced was how best to define when an image is of the dorsal or perpendicular side of a whale’s tailstock because there were photos that were a mix of both body parts as seen in Figure 1. In the end, we chose to classify photos that did not show a clear view of both insertion points of the fluke into the tailstock as a perpendicular tailstock. It is important to make this distinction because the view of a whale’s body part can show very different markings that could change our perspective of the whale’s possible entanglement history. We also have to assess the quality of each image because the quality can hide or show details that could influence our ability to access the whale’s history. The quality of the photos range from being very good to being illegible, which can make scoring a bit difficult. Aside from these issues, I have been making progress and I have been enjoying the work that I am doing knowing could help researchers in the future. This area of research is something that I could possibly pursue in the future because I enjoy working in an area helping with conservation efforts.

In addition to my research project, I am also expanding my personal connections and boundaries.  I have started to feel more comfortable here in Newport, although I do miss my family. Everyone in the GEMM lab, as well as in the MMI in general, was very welcoming and kind so that made things easier to settle in. I have also been learning about other projects occurring since everyone has been showing off all the amazing videos and data being collected.  

It’s hard to believe that it’s already been four weeks since I’ve arrived in Oregon. Had anyone told me that after my freshman year of college I would spend an entire summer in Oregon studying humpback whales scarring I would have never believed them and called them crazy. I’ve spent the majority of my life in Ohio thinking that it’d be impossible to study marine biology. But yet I was offered the opportunity to work in the GEMM lab and I will always be thankful for the opportunity.

Confidence has always been a struggle for me, but I wanted to challenge my insecurities, so I put myself out there in my application. Doing so opened up this opportunity and it makes me glad that I took the chance. Internships are a great way to build up confidence while gaining research experience, especially this one. I have met many amazing and kind people here and it has created an amazing atmosphere here at the Hatfield Marine Science Center. So, this is my message to everyone: take the chance and reach out because the opportunity could be an arm’s length away.

Roger Payne: A life dedicated to whale conservation

By Dr. Alejandro A. Fernández Ajó, Postdoctoral Scholar, Marine Mammal Institute – OSU Department of Fisheries, Wildlife, & Conservation Sciences, Geospatial Ecology of Marine Megafauna (GEMM) Lab.

On Saturday, June 10, Dr. Roger Payne passed away. Throughout his remarkable life, he made impactful contributions to the study, understanding, and conservation of whales. His passion, research, and advocacy efforts played a pivotal role in reshaping public perception, and thus promoting the conservation of these giants, profoundly influencing generations of researchers in the field of conservation biology, including myself.

In 1970, Roger and his first wife Katy Paine began the Southern Right Whale (SRW) Research Program in Patagonia, Argentina, which in 1996 was continued by the Whale Conservation Institute of Argentina (the ICB) , becoming the longest continually running research program on a great whale (based on known individuals) in existence. In this study, Dr. Payne recognized that individual whales can be identified by the unique marks on their heads, establishing an important milestone for photo-ID, a technique that forms the bedrock of whale science.

I am proud to say that I am part of his legacy, as a member of the ICB. With the SRW program, I continued advancing research on SRW through my doctoral dissertation by advancing methods in conservation physiology (see blog post) to understand the underlaying mechanisms affecting young whales’ mortality in Patagonia (see blog post ).

Probably, one of the most remarkable contributions of Dr. Payne to the field and to whale conservation was his groundbreaking discovery of the humpback whale song. In the mid-20th century, the world’s whale populations were intensively killed by commercial whalers, threatening their extinction. In the late 1960s, Payne and his collaborators unveiled the melodic symphonies of humpback whales, marking the start of modern whale biology and catalyzing the global conservationist movement “Save the Whales”. These haunting songs connected humans with these enigmatic animals in an emotional manner, raising public opinion and support for whale conservation that ultimately led to the global moratorium on commercial whaling in 1982.

While he continued to believe that science provides essential information about the necessary changes needed to protect whales, Dr. Payne strongly believe in that the paths to accelerate these changes often involve a combination of activism and creative arts.

…All of the great movements in human history have been based not on data but on emotion and passion, and a dream of a better society and a better life. For unless people connect emotionally with a problem they won’t connect with the numbers and the data that describe its dimensions…

“…It seems highly likely that the changes we so desperately need will only come by invoking emotions, and that is something that poets, musicians, writers, playwrights, sculptors, painters, dancers, composers—in fact, creative people of every stripe do well, but that scientists do at their peril. For the real challenge here is to get the world to fall so deeply in love with Nature that we will no longer tolerate the destruction of creation, and will risk our careers and our lives to save all plankton, mosses, ferns, trees, flowers, jellyfish, crinoids, nautiloids, crabs, bees, butterflies, beetles, squid, fishes, frogs, turtles, birds, and mammals—in other words, we will fight to save all of the non-human “Other”…”

From the “Final Voyage

Roger Payne’s influence and legacy continue to inspire generations of scientists and conservationists. His work expanded our understanding of whales, deepened our empathy for these creatures, and paved the way for international collaborations aimed at protecting marine life and preserving our oceans. Today, there are many of us who, inspired by Roger, dedicate our lives to research, environmental education, and conservation. And following Roger’s teachings, we constantly ask questions to seek answers that allow us to continue learning about whales in a changing world.

Exploring the Western Antarctic Peninsula  

By Abby Tomita, undergraduate student, OSU College of Earth, Ocean, and Atmospheric Sciences, research intern in the GEMM and Krill Seeker Labs

This February, during the winter term of my third year at Oregon State, I was presented with a once-in-a-lifetime opportunity. After spending the last year studying the zooplankton krill as part of Project OPAL, I was invited to spend the austral winter season doing research on Antarctic krill (Euphausia superba) under supervision of experts Dr. Kim Bernard and PhD student Rachel Kaplan. Additionally, we were lucky enough to participate in two research cruises along the Western Antarctic Peninsula (WAP). 

Figure 1. Sailing into the sunset on the RV Laurence M. Gould.

Unsurprisingly, it is no easy feat getting to the bottom of the world. After an incredibly thorough physical qualification process and two days of air travel from Portland, Oregon, we reached the lovely city of Punta Arenas, Chile. It was such a relief to arrive – but we were only halfway there. The next portion of our trip was the one that I was most anxious about, especially as someone who is prone to seasickness: crossing the Drake Passage. This stretch of the ocean, from the southernmost tip of South America to the Antarctic Peninsula, is notoriously treacherous as water in this area circulates the globe completely unobstructed by land masses. I soon learned the value of scopolamine patches and nausea bracelets, which helped me immensely through this five day journey. From Punta Arenas, we boarded the RV Laurence M. Gould, along with a seal research team from the University of North Carolina Wilmington. They were headed down south to look for crabeater seals to better understand not only their physiology, but also their role in the trophic ecology of the WAP. 

The Passage was rough, but not as terrible as I expected. The hype around it made me think I’d be faced with something as menacing as the giant wave from The Perfect Storm, and while the rocking and rolling of the ship was far from pleasant, my nausea aids, as well as the amazing people and vast selection of movies on board made it manageable. Despite being extremely nervous for the Passage, I was also very excited to celebrate my twenty-first birthday during it. It was a memorable, although untraditional birthday experience that was made all the more special by my friends on the ship who took the time to celebrate the day as best as we could. 

Figure 2. Taking in the sights of the Neumayer Channel with Kim!

The morning that we reached the Bransfield Strait was something truly unforgettable. Up until that point, I knew our destination was Antarctica, but I couldn’t really wrap my head around it because it was such a distant place and concept to me. I remember walking out onto the starboard side of the second level deck and seeing huge mountains out in the distance. For some reason, I had never considered how massively tall the mountains of the peninsula are, and just the fact that there were mountains down here at all. I joined the others at the bow, where we stood for hours in awe at the first land we had seen in days. Though many of the other scientists and crew members on board had been to this icy continent before, this was my first time, and I was in a state of disbelief. We’d finally made it and it sunk into me that I was in Antarctica, and that I would be here for the next five and half months.

After a day of hiding from strong winds in the Neumayer Channel, we were able to dock at Palmer Station (the smallest of the three US research bases in Antarctica) for our first port call, and seeing Palmer for the first time was just as exciting as seeing the continent. It looked so small at first, especially with the glacier and mountains looming behind it. Once the ship was tied up, orientation began. The station manager came onto the ship to give us an overview of what we could expect on station and the general Palmer etiquette. Next, we were given a tour of the facilities, from the lab spaces and aquarium room, up through the galley/dining area, past the hot tub and sauna, and into the lounge and bar in the GWR (Garage, Warehouse, and Recreation) building. I was surprised at how cozy the station was on the inside. In pictures, the buildings’ exteriors looked similar to the outside of a metal shipping container, but the inside was welcoming and warm. Those of us staying on station then sat through several hours of a more detailed orientation that somehow wore us out despite sitting in comfy recliner sofas the whole time. After sleeping on the rocking ship for about a week, I had some of the best sleep of my life that first night at Palmer Station.

Figure 3. Arriving at the Palmer Station pier in the first morning light.

Our first research cruise started a few days after arriving at Palmer, and just like that, we were off to explore the Southern Ocean. This leg of the trip took us south, down to Marguerite Bay and the region of Alexander Island, for ten days. The views were just spectacular everywhere we went, and it was so humbling to step out onto the deck to see gigantic mountains all around the ship. By day, us “krillers”, as our team is known, camped out on the bridge of the ship with the seal team, where we looked for sea ice floes with lounging crabeater seals. By night we conducted CTD casts, filtered water for chlorophyll, and deployed nets to catch our favorite tiny crustacean critters, along with any other zooplankton in our track. Unfortunately for both our group and the seal team, many areas that we visited were not frequented by krill or crabeater seals, though the seal team did successfully study and tag one seal over the course of the first cruise. 

Figure 4. Rachel (right) and I (left) filtering water for chlorophyll on the LMG. 

One of the highlights of this leg of the cruise was our Crossing Ceremony, as we’d crossed the Antarctic Circle (approximately 66.5ºS) shortly after leaving Palmer station. Myself and six others were crossing for the first time, so to earn our “Red Noses”, we had to pay tribute to King Neptune and his court. It would not be a Crossing Ceremony without at least some light pranking, so when they brought us out individually to the main deck, I knew something was coming our way.

Figure 5. Taking a celebratory picture with King Neptune’s court…with a surprise after.

The ten days flew by, and when we arrived back on station, we had less than a week to prepare for our next excursion on the LMG, which would be fifteen days. The time back at Palmer went quickly as we organized our lab space and entered data from the first cruise. The ship came back once more and we were off, this time heading north along the Peninsula to the Gerlache Strait. The sights were as breathtaking as ever, and I was excited to be back with my friends from the ship. 

Figure 6. Kim (left) and I (right) pour krill we caught into an XACTIC tank.

Our first day of transit was through the Lemaire Channel, one of the most stunning areas that we passed through (check out the photo gallery at the end of this post!). We spent the majority of the day on the bow and the deck of the bridge taking in the beautiful towering mountains on either side of the narrow channel and watching for penguins and humpbacks, of which there were many. This voyage segued into an extremely productive night of science for us where we caught thousands of krill that we were able to keep live in tanks on the ship, in preparation for later use for our experiments on station. Our first productive night of science was auspicious for the rest of the cruise as we caught and processed thousands more krill, and the seal team had a much more fruitful experience finding crabeater seals (they found/worked on 8 seals and named them all after fruits!). The highlight of this second cruise for me was getting to accompany the seal team onto an ice floe in the Lemaire Channel to assist them in their work on the crabeater, a female juvenile who they named Mango!

Figure 7. Watching Mango’s nose to calculate and record her breaths per minute (US NMSF Permit #25770).

Returning to Palmer for the final time on the LMG was just as exciting as arriving the first time, especially with the knowledge that we’d have one last night of celebration with our friends from the ship at the Cross Town Dinner – a night to celebrate the solstice with both the Palmer crew and LMG crew. Although the dinner and subsequent party were a blast, I felt a lingering sadness knowing that the majority of the people I spent almost two months with would be heading north, back to their respective homes while Kim, Rachel, and I stayed at Palmer for the next few months. The next day, after saying our goodbyes, the three of us stood on the Palmer pier with tears streaming down our faces, waving frantically at the ship to our friends on the deck. In spite of my sadness, I knew that the coming months would be a thrilling series of new experiences in one of the most magical and special places that I have ever had the pleasure of being in.

The Way Forward is the End

By Morgan O’Rourke-Liggett, M.S., Oregon State University, Department of Fisheries, Wildlife, and Conservation Sciences, Geospatial Ecology of Marine Megafauna Lab

It is the end.

I graduated with a Master’s degree.

This journey began 10 years ago when I visited colleges as a high school junior.

Begin with the end in mind. 

I knew I would major in science as an undergrad and focus on something more specific as a graduate student. Studying whales required a background in marine biology, which led to my undergraduate degree in oceanography with strong emphasis in fisheries and wildlife, policy, and ecology. My master’s degree was built on that and added specific skills in data collection, management, and analysis.

The last time I wrote a blog, I was sharing the details of the data management and intricacies of my master’s project. Part of what made that project so successful was knowing the end goal: we wanted to know the area surveyed based on visibility and a visual representation of it. This knowledge aided in the development of matrices for environmental conditions, assigning integer variables to text survey notes, and determining what toolboxes and packages would be the most appropriate for analysis.

As a visual learner, I like to sketch out what I am doing or draw it on a whiteboard in a concept board. This approach is something I have always done and was further reinforced as a necessary step in my programming classes early on in my master’s education. My professors would assign a problem that could be solved in programming by making a function or script of code. We were taught to write out what our end goals were and what inputs were available for the problem. From there, filling in what steps were needed would be added. That was a critical step that made writing many difficult Python and R for loops and functions easier to build.

This skill and mentality of “beginning with the end” in mind can also be useful in preparation for data collection. There are eleven common data types that are described with examples in Table 1. Understanding what data type is being collected could save several hours of data management and wrangling during the data analysis phase. From my experience in data analytics, some models yield more accurate results if the character data is manipulated to behave like an integer in R. Additionally, certain packages and toolboxes in R and GIS are only useful for certain data types.

Data TypeDefinitionExample
Integer (int)Numeric data without fractions-707, 0, 707
Floating point (float) or DoubleNumeric data with fractions707.07, 0.7, 707.00
Character (char)Single letter, digit, space, punctuation mark, symbola, !
String (str or text) or ComplexSequence of characters, digits, or symbolsHello, +1-999-666-3333
Boolean (bool) or LogicalTrue or false values0 (false), 1 (true)
Enumerated type (enum)Small set of predefined values that can be text or numericalrock (0), jezz (1)
ArrayList with a number of elements in a specific orderrock (0), jazz (1), blues (2), pop (3)

Table 1. Table of the eleven most common data types with a short definition and an example of the data type. Table inspired by (Choudhury 2022).

Beginning with the end in mind allows more clarity and strategies to be efficient and achieve your goal. It develops a better understanding of why each stage of data collection and analysis is important; why each stage in a career is important. It provides a road map for what will, undoubtedly, be an incredible learning experience.

Familiar flukes and flanks: The 9th GRANITE field season is underway

By Lisa Hildebrand, PhD student, OSU Department of Fisheries, Wildlife, & Conservation Sciences, Geospatial Ecology of Marine Megafauna Lab

The winds are consistently (and sometimes aggressively) blowing from the north here on the Oregon coast, which can only mean one thing – summer has arrived! Since mid-May, the GRANITE (Gray whale Response to Ambient Noise Informed by Technology and Ecology) team has been looking for good weather windows to survey for gray whales and we have managed to get five great field work days already. In today’s blog post, I am going to share what (and who) we have seen so far.

On our first day of the field season, PI Leigh Torres, postdoc KC Bierlich and myself, were joined by a special guest: Dr. Andy Read. Andy is the director of the Duke University Marine Lab, where he also runs his own lab, which focuses on conservation biology and ecology of marine vertebrates. Andy was visiting the Hatfield Marine Science Center as part of the Lavern Weber Visiting Scientist program and was hosted here by Leigh. For those of you that do not know, Andy was Leigh’s graduate school advisor at Duke where she completed her Master’s and doctoral degrees. It felt very special to have Andy on board our RHIB Ruby for the day and to introduce him to some friends of ours. The first whale we encountered that day was “Pacman”. While we are always excited to re-sight an individual that we know, this sighting was especially mind-blowing given the fact that Leigh had “just” seen Pacman approximately two months earlier in Guerrero Negro, one of the gray whale breeding lagoons in Mexico (read this blog about Leigh and Clara’s pilot project there). Aside from Pacman, we saw five other individuals, all of which we had seen during last year’s field season.

Since that first day on the water, we have conducted field work on four additional days and so far, we have only encountered known individuals in our catalog. This fact is exciting because it highlights the strong site fidelity that Pacific Coast Feeding Group (PCFG) gray whales have to areas within their feeding range. In fact, I am examining the residency and space use of each individual whale we have observed in our GRANITE study for one of my PhD chapters to better understand the level of fidelity individuals have to the central Oregon coast. Furthermore, this site fidelity underpins the unique, replicate data set on individual gray whale health and ecology that the GRANITE project has been able to progressively build over the years. So far during this field season in 2023, we have seen 13 unique individuals, flown the drone over 10 of them and collected four fecal samples from two, which represent critical data points from early on in the feeding season.

Our sightings this year have not only highlighted the high site fidelity of whales to our study area but have also demonstrated the potential for internal recruitment of calves born to “PCFG mothers” into the PCFG. Recruitment to a population can occur in two ways: externally (individuals immigrate into a population from another population) or internally (calves born to females that are part of the population return to, or stay, within their mothers’ population). Three of the whales we have seen so far this year are documented calves from females that are known to consistently use the PCFG range, including our central Oregon coast study area. In fact, we documented one of these calves, “Lunita”, just last year with her mother (see Clara’s recap of the 2022 field season blog for more about Lunita). The average calf survival estimate between 1997-2017 for the PCFG was 0.55 (Calambokidis et al. 2019), though it varied annually and widely (range: 0.34-0.94). Considering that there have been years with calf survival estimates as low as ~30%, it is therefore all the more exciting when we re-sight a documented calf, alive and well!

“Lunita”, an example of successful internal recruitment

We have also been collecting data on the habitat and prey in our study system by deploying our paired GoPro/RBR sensor system. We use the GoPro to monitor the benthic substrate type and relative prey densities in areas where whales are feeding. The RBR sensor collects high-frequency, in-situ dissolved oxygen and temperature data, enabling us to relate environmental metrics to relative prey measurements. Furthermore, we also collect zooplankton samples with a net to assess prey community and quality. On our five field work days this year, we have predominantly collected mysid shrimp, including gravid (a.k.a. pregnant) individuals, however we have also caught some Dungeness and porcelain crab larvae. The GEMM Lab is also continuing our collaboration with Dr. Susanne Brander’s lab at OSU and her PhD student Lauren Kashiwabara, who plan on conducting microplastic lab experiments on wild-caught mysid shrimp. Their plan is to investigate the growth rates of mysid shrimp under different temperature, dissolved oxygen, and microplastic load conditions. However, before they can begin their experiments, they need to successfully culture the mysids in the lab, which is why we collect samples for them to use as their ‘starter culture’. Stay tuned to hear more about this project as it develops!

So, all in all, it has been an incredibly successful start to our field season, marked by the return of many familiar flukes and flanks! We are excited to continue collecting rock solid GRANITE data this summer to increase our efforts to understand gray whale ecology and physiology.

Title: “Blown away”: measuring the blowholes of whales from drones

By Annie Doron, Undergraduate Intern, Oregon State University, GEMM Laboratory  

Hey up! My name is Annie Doron, and I am an undergraduate Environmental Science student from the University of Sheffield (UK) on my study year abroad. One of my main motivations for undertaking this year abroad was to gain experience working in a marine megafauna lab. Whales in particular have always captivated my interest, and I have been lucky enough to observe  humpback whales in Iceland and The Azores, and even encountered one whilst diving in Australia! For the past 10 months, I have had the unique opportunity to work in the GEMM Lab analyzing Pacific Coast Feeding Group (PCFG) gray whales off the Oregon Coast (Figure 1). I must admit, it has been simply wonderful! 

Figure 1. Aerial image of a PCFG gray whale off the Oregon Coast. 

How did I end up getting involved with the GEMM Lab? I was first accepted into Scarlett Arbuckle’s research-based class in fall term 2022, which is centered around partnering with a mentor for a research project. Having explored the various fields of research at HMSC, I contacted Leigh Torres with interest in getting involved in the GEMM Lab and to establish a research project suitable for a totally inexperienced, international, undergraduate student. Thankfully, Leigh forwarded my email to KC Bierlich who offered to be my mentor for the class, and the rest is history! I first began analyzing drone imagery to measure length and body condition of  PCFG gray whales, which provided an opportunity to get involved with the lab and gain experience using the photogrammetry software MorphoMetriX (Torres & Bierlich, 2020) (see KC’s blog), which is used to make morphometric measurements of whales. Viewing drone imagery of whales sparked my interest in how they use their blowholes (otherwise called ‘nares’) to replenish their oxygen stores; this led to us establishing a research project for the class where we tested if we could use MorphoMetriX to measure blowholes from drone imagery.

Extending this project into winter and spring terms (via research credits) has enabled me to continue working with Leigh and KC, as well as to collaborate with Clara Bird and Jim Sumich. Thanks to KC, who has patiently guided me through the ins and outs of working on a research project, I now feel more confident handling and manipulating large datasets, analyzing drone footage (i.e., differentiating between behavioral states, recording breathing sequences, detecting when a whale is exhaling vs inhaling, etc.), and speaking in public (although I still get pretty bad stage fright, but I think that is a typical conundrum undergrads face). Whatsmore, applying  R – a programming language used for statistical analysis and data visualization, which I have been trying to wrap my head around for years – to my own dataset has helped me greatly enhance my skills using it. 

So, what exciting things have we been working on this year? Given that we often cannot simply study a whale from inside a laboratory – due to size-related logistical implications – we must use proxies (i.e., a variable that is representative of an immeasurable variable). Since cetaceans must return to the surface to offload carbon dioxide and replenish their oxygen stores, measuring their breath frequency and magnitude is one way to study a whale’s oxygen consumption, in turn offering insight into its energy expenditure (Williams, 1999). Blowholes are one proxy we can use to study breath magnitude. Blowholes can be utilized in this way by measuring inhalation duration (the amount of time a whale is inhaling, which is based on a calculation developed by Jim Sumich) and blowhole area (the total area of a blowhole) to gauge variations in tidal volume (the amount of air flowing in and out of the lungs).

Measuring inhalation duration and blowhole area is important because a larger blowhole area (i.e., one that is more dilated) and a longer inhalation duration is indicative of higher oxygen intake, which can infer stress. For example, in this population, higher stress levels are associated with increased vessel traffic (Lemos et al., 2022), and skinnier whales have higher stress levels compared to chubby, healthy whales (Lemos, Olsen, et al., 2022). Hence, measuring the variation around blowholes could be utilized to predict challenges whales face from climate change and anthropogenic disturbance, including fishing (Scordino et al., 2017) and whale watching industry threats (Sullivan & Torres, 2018) (see Clara’s blog), as well as to inform effective management strategies. Furthermore, measuring the variables inhalation duration and blowhole area could help to identify whether whales are taking larger breaths associated with certain ‘gross behavior states’, otherwise known as ‘primary states’, which include: travel, forage, rest, social (Torres et al., 2018). This could enable us to assess the energetic costs of different foraging tactics (i.e., head standing, side-swimming, and bubble blasting (Torres et al., 2018), as well as consequences of disturbance events, on an individual and population health perspective. 

Inhalation duration has been explored in the past by using captive animals. For example, there have been studies on heart rate and breathing of bottlenose dolphins in human care facilities (Blawas et al., 2021; Fahlman et al., 2015). Recently, Nazario et al. (2022) was able to measure inhalation duration and blowhole area using suction-cup video tags. Her study led us to consider if it was possible to measure the parameters and variation around respiration by measuring blowhole area and inhalation duration of PCFGs from drone imagery. We employed MorphoMetriX to study the length, width, and area of a blowhole (Figure 2). Preliminary analyses verified that the areas of the left and right blowholes are very similar (Figure 3); this finding saved us a lot of time because from thereon we only measured either the left or right side. Interestingly, we see some variation in blowhole area within and across individuals (Figure 4). This variation changes within individuals based on primary state. For example, the whales “Glacier”, “Nimbus”, and “Rat” show very little variation whilst traveling but a large amount whilst foraging. Comparatively, “Dice” shows little variation whilst foraging and large variation whilst traveling. Whilst considering cross-individual comparisons, we can see that “Sole”, “Rat”, “Nimbus”, “Heart”, “Glacier”, “Dice”, and “Coal” each exhibit relatively large amounts of variation, yet “Mahalo”, “Luna”, “Harry”, “Hummingbird” and “Batman” exhibit very little. One potential reason for some individuals displaying higher levels of variation than others could be higher levels of exposure to disturbance events that we were unable to measure or evaluate in this study.

Figure 2. How we measured the length, width, and area of a blowhole using MorphoMetriX.

Figure 3. Data driven evidence that the left and the right blowhole areas are very similar. 

Figure 4. Variation in blowhole area amongst individual PCFG whales. The hollow circles represent the means, and the color represents the primary state the whale is exhibiting, foraging (purple) vs. traveling (blue), which will be further explored in Clara’s PhD.

Now, we are venturing into June and are at a stage where we (KC, Clara, Jim, Leigh, and I) are preparing to publish a manuscript! What a way to finish such a fantastic year! The transition from a 3-month-long pilot study to a much larger data analysis and eventual preparation for a manuscript has been a monumental learning experience. If anybody had told me a year ago that I would be involved in publishing a body of work – especially one that is so meaningful to me – I would simply not have believed them! We hope this established methodology for measuring blowholes will help other researchers carry out blowhole measurements using drone imagery across different populations and species. Further research is required to explore the differences in inhalation duration and blowhole area between different primary states, specifically across different foraging tactics.

It has been a great privilege working with the GEMM Lab these past months, and I was grateful to be included in their monthly lab meetings, during which members gave updates and we discussed recently published papers. Seeing such an enthusiastic, kind, and empathic group of people working together taught me what working in a supportive lab could look and feel like. In spite of relocating from Corvallis to Bend after my first term, I was happy to be able to continue working remotely for the lab for the remainder of my time (even though I was ~200 miles inland). I thoroughly enjoyed living in Corvallis, highlights of which were scuba diving adventures to the Puget Sound and coastal road trips with friends. The appeal to move arose from Bend’s reputation as an adventure hub – with unlimited opportunities for backcountry ski access – as well as its selection of wildlife ecology courses (with a focus on species specific to central Oregon). I moved into ‘Bunk & Brew’ (Bend’s only hostel, which is more like a big house of friends with occasional hostel guests) on January 1st after returning from spending Christmas with friends in my old home in Banff, Canada. I have since been enjoying this wonderful multifaceted lifestyle; working remotely in the GEMM Lab, attending in-person classes, working part-time at the hostel, as well as skiing volcanoes (Mount Hood, Middle and South Sister (Figure 5) or climbing at Smith Rock during my days off. Inevitably, I do miss the beautiful Oregon coast, and I will always be grateful for this ideal opportunity and hope this year marks the start of my marine megafauna career!
