Our [student] Life on the Ocean

Posted on May 31, 2023June 13, 2023 by Hannes Baumann

By Ewaldo Leitao.
When we say we work or study oceanography, it is common for us to be met with a: “Wow, you must spend a lot of time doing cool stuff in the ocean then!” Alas, most of us spend most of our time on a computer. However, cruises are still an essential part of oceanographic research to collect the necessary data or test equipment. In our department, many students have this opportunity to participate in such cruises; all with fascinating and unique research interests. Over the past year, several students joined cruises to get familiar with field techniques, collect their own data, or to better understand their study area. In this piece, graduate students in our Marine Sciences department shared their experiences in cruises that took place from Summer 2022 up to May 2023.

“In the Summer 2022 I participated in the Sea Education Association (SEA) summer cruise through the great pacific garbage patch, which sailed from Honolulu, HI to San Diego CA, starting In late June and ending in late July. SEA typically runs programs with undergraduates, who take part in cruises to learn about oceanography, sailing, and earn course credit. As a grad student, I was able to tag along as a visiting scientist and focus on collecting data.

My research focused on taking optical measurements, such as spectral reflectance, of freshly-collected plastic pieces. Previous work has been published on plastic spectral reflectance properties, but these measurements were made on dried and stored samples. Out in the environment, plastic pieces are likely to have some degree of biofilming growing on them. So, I sought to collect spectral reflectance measurements of freshly collected plastics in order to assess how the presence of biofilms might impact plastic spectral reflectance. Knowing this will be useful for sensitivity analyses seeking to develop a satellite-based ocean plastic detection algorithm.

During the cruise, I conducted daily neuston net tows to collect plastic pieces. Neuston nets are towed along the surface of the water to collect as many buoyant plastic pieces as possible. Once collected, I rinsed the plastics out of the net and into a bucket, then picked them out and aggregated them for spectral measurement.”

“I participated in NASA’s Sub-Mesoscale Ocean Dynamics Experiment (S-MODE) IOP1 as part of the science party aboard the R/V Bold Horizon. The cruise took place from 10/06/2022 – 11/04/2022 in the Pacific Ocean, approximately 100 miles offshore of San Francisco, California. The focus of this experiment was to sample ocean fronts that are a few kilometers in size to study their dynamics and effects on vertical transport. The ocean fronts were sampled using aircraft, ship surveying, and autonomous platforms such as wave gliders, sea gliders, saildrones, floats, and drifters. I worked the night shift from 4pm – 4am, running an instrument called an EcoCTD, which measures temperature, salinity, pressure, chlorophyll, backscatter, and oxygen. I also helped with the recovery and deployment of wave gliders and mixed layer floats.

I am currently (03/06/2023 – 04/06/2023) aboard NOAA’s R/V Ronald H. Brown for U.S. GO-SHIP’s decadal reoccupation of A16N in the Atlantic Ocean. I am participating in the first leg of the cruise, sailing from Brazil to Spain. The second leg of the cruise will be sailing from Spain to Iceland. This is a longline hydrographic cruise, where we take CTD casts at many stations along the same longitude line. The CTD rosette has 24 bottles and is deployed to the bottom of the ocean. I am working with Dr. Chris Langdon’s research lab out of the University of Miami. The Langdon lab is leading measurements on oxygen, pH, and total alkalinity. I am overseeing pH measurements using a spectrophotometer. Other groups are taking measurements which include DIC, DOC, CFCs, velocity, temperature, salinity, and biological samples. The best part of my trip so far has been getting to explore Brazil, crossing the equator, and viewing beautiful sunrises every morning.”

Yipeng He, alumnus of the Mason Mercury Lab, studied air-sea mercury exchange in the ocean for his PhD, also had cool research experiences in cruises.

“I was on a scientific cruise - the GEOTRACES GP17 cruise, leaving San Diego (CA) on Nov 13 2022. Going from North Pacific to South Pacific, crossing the Equator, going further south and crossing the Antarctic cycle, and arriving at Punta Arena (Chile) on Jan 25 (2023). The boat was R/V Roger Revelle, which was my second time sailing on this boat. The first time was the GEOTRACES GP15 cruise in 2018. I was collecting samples and measuring atmospheric mercury species, air-sea exchange of mercury species and surface ocean Beryllium-7 profile.”

Heat tolerance changes across environments and populations

Posted on March 27, 2023March 27, 2023 by Hannes Baumann

March 27th 2023 - By Ewaldo Leitao.

Climate change is a threat to species persistence. Increasing temperatures affect species differently depending on their habitats, such as land or the ocean. However, species often consist of different populations (groups of individuals that reproduce together) that experience different temperature conditions. And if populations live in these areas long enough, they can genetically adapt to their local conditions. What does that mean? If the same species has a population in an area where it is constantly warm, like the tropics, and another population that lives in colder regions, like Connecticut, then we’d expect the tropical population to handle high temperatures better compared to the population living in colder regions. This kind of diversity within species affects how we think about the vulnerability of the species as a whole. To add another layer, if variation differs for terrestrial vs. oceanic species, we might be missing important information about where climate change will have the strongest effects on the planet.

That is what Dr. Matt Sasaki and collaborators investigated in a paper recently published in Nature Climate Change. Their main goal was to assess the heat tolerance (the highest survivable temperature) of populations in many different species, from different realms – terrestrial, freshwater, marine and intertidal. They assessed the vulnerability of species by surveying in the literature from the whole world that measured individual heat tolerance. They compiled and then conducted a meta-analysis of these published data, thereby assessing how the heat tolerance is related to the thermal environment these populations live in.

“This paper came out of the ‘Evolution in Changing Seas’ Research Coordination Network (RCN). Back in 2019 they brought some of us together at Shoal’s Marine Lab for a synthesis workshop and essentially told us to think about questions at the intersection of evolutionary biology and marine science”, said Matthew Sasaki, about the seed of the idea.

"I really enjoyed the collaborative aspect of this project, even though I’ve met most of the co-authors in person only once (or not at all!)"

By measuring how heat tolerance changes between populations of the same species, they found that marine and intertidal species show a decrease of heat tolerance between populations as the environment gets colder, but that was not observed in terrestrial and freshwater populations. This was an interesting result, because since the ocean is largely connected, they expected that there would be a smaller differentiation in the ocean compared to land, where geographical barriers can create physical separations, allowing difference in heat tolerance to build up among populations within a species.

Behavior may play a role in the observed patterns. In the terrestrial realm, many organisms can moderate body temperature by seeking shade and forested areas to find refuges from the heat. Even plants can exploit micro-climates. This decreases the amount of evolutionary pressure on terrestrial organisms, when compared to other realms.

This study highlights the importance of accounting for evolutionary processes in the context of climate change and species persistence and extinction risk. Larger differentiation of heat tolerance within species may suggest a potential for evolutionary rescue. That is, populations with genes that allow them to be “warm adapted” may rescue populations that are more susceptible to increasing warming.

We asked what was the coolest part about the execution and findings of the project. “This wasn’t a project someone could do alone, and it was really cool to be part of such a big collaborative effort. The findings themselves were also really exciting for us. We expected there to be pretty clear differences between marine and terrestrial taxa, but we were surprised to see that local adaptation seems to be stronger in marine species and not terrestrial species. This goes against some of the traditional paradigms (that marine species’ are more often homogenized by larval dispersal, for example), and hints at a cool role of behavioral thermoregulation in shaping patterns in evolutionary adaptation.”

“This was definitely a pandemic pet project. I won’t say the pandemic helped us make progress though. This ended up being something we worked on a little bit each week for a couple years. Maybe that helped us put together a more robust product (slow and steady wins the race?). I really enjoyed the collaborative aspect of this project, even though I’ve met most of the co-authors in person only once (or not at all!). Having to do everything virtually definitely changed the nature of the collaboration (more written exchanges, less whiteboard brainstorming) but I think we made it work. We’ve just started working together on a couple new projects that build from this initial work, so it must not have been too terrible.”, said Matt.

Sampling freshwater mussel gut microbiomes in the Great Lakes

Posted on March 17, 2023March 17, 2023 by Hannes Baumann

In June 2022, Hannah Collins and Tyler Griffin from the Ward Environmental Physiology Lab went to Buffalo, NY, to perform research on the gut microbiomes of freshwater quagga mussels (Dreissena bugensis). The three-day trip involved collecting these invasive mussels from Lake Erie with the help of Brian Haas at the Buffalo State Great Lakes Center field station. The goal of the project, funded by an NSF Emerging Frontiers in Research and Innovation grant, was to sample mussel gut microbes before and after defecation with the goal of distinguishing between microbes that live inside the mussels and other microbes that were simply passing through. This work serves as preliminary research for the larger goal of investigating the feasibility of using freshwater mussels to remove microplastics from freshwater systems and co-concentration them with plastic-degrading bacteria.

Jamie Vaudrey selected for Faculty Environmental Leadership Award

Posted on March 16, 2023March 17, 2023 by Hannes Baumann

16 March 2023. DMS is proud to announce that Prof. Jamie Vaudrey has been selected for the 2023 Faculty Environmental Leadership Award (ELA). This award recognizes individuals who have worked alone or as part of organizations to support sustainability efforts at UConn and beyond.

Since 2005, the Office of Sustainability, within the Institute of the Environment has honored faculty members, students and staff members who have made a positive impact on the environment through their leadership in the classroom, lab, or in the communities which UConn serves

Dr. Vaudrey was nominated, because of her exemplary role as an environmental leader over the past years. She sets the standard for outreach in the Department of Marine Sciences. Communicating science is the fiber that runs through all of her research and teaching. She does this across a broad array of stakeholders often with competing interests. Her outreach extends well beyond advisory to active partnerships with citizen scientists, regulators, municipalities, and industry. It has helped to shape the stewardship trajectories of waters and watersheds regionally, and seagrass ecosystems worldwide.

Her leadership roles in professional societies and on advisory councils have pushed for more integration of scientific results into decision making and broadened participation of underrepresented groups in marine science. Dr. Vaudrey’s key role in gathering the momentum for establishing the Connecticut National Estuarine Research Reserve was her crowning achievement of years of meticulous, patient teamwork, where she led countless meetings to bring experts, policymakers and public stakeholders to the table and eventually, through dialogue and her own unique way of gentle persuasion, make the CT NERR a reality in 2022.

In addition, Dr. Vaudrey has led numerous, hands-on team efforts in recent years to work on sea grass restoration and living shorelines initiatives, where she has been inspiring students and volunteers by practically working alongside them in the field. Dr. Vaudrey’s compassion for nature and the future of Long Island Sound emanates from her everyday work, which is a key motivating force for every member of her team.

Dr. Vaudrey also works with Save the Sound and helped develop an Environmental Report Card for Long Island Sound which has engaged senators and other state and federal agencies to seek additional funding for research on environmental impacts on local waters. Jamie is also the Coordinator for the Niantic River Watershed Committee, and she is an outspoken advocate for environmental issues in our local marine waters. Her impact on understanding of environmental and sustainability impacts in CT’s local waters reaches far beyond the classroom, but she is devoted to educating the next generation of scientists and managers on these important issues.

Prof. Catherine Matassa wins UConn-AAUP Teaching excellence award

Posted on March 16, 2023June 1, 2023 by Hannes Baumann

23 March 2023. DMS is proud to share that Prof. Catherine Matassa has been selected for a 2023 UConn-AAUP Excellence Award in the Early Career Teaching category. This is well deserved, because since joining our department, Catherine has distinguished herself as one of the most cherished, effective and innovative educators for undergraduate and graduate students of our Department and CLAS. Her enthusiasm for Marine Biology and her innovative approach to teaching Quantitative Methods and Experimental Design are a true enrichment to students and faculty alike.

Here are some excerpts of what colleagues and students had to say about Catherine's teaching:

"In addition to providing the foundational basis of marine ecosystems, she facilitates transformative learning experiences with hands-on laboratory and field activities where students apply their knowledge and conduct independent research. Courses where students conduct independent research require much larger investment of time and energy from the instructor." Prof. Heidi Dierssen

"Almost from the time I arrived at UConn in 1995, I heard colleagues in Marine Sciences discussing the need for an Experimental Design/Statistics course for our students. Being located at Avery Point has always limited our participation in Storrs-based classes, so we tried, and failed, several times to develop a course of our own. When Catherine arrived, the problem was solved. Her class, MARN 4210Q Experimental Design in Marine Ecology, covers the basics of hypothesis testing and gives students a good working knowledge of R, the state-of-the-art computing environment for scientific statistics." Prof. George McManus

"Catherine created the experimental design and analysis course to address the demand for a course that covered statistics, coding and design. The course provided us with real data to run analyses on in R and posed questions, which we addressed with experimental design. The homework was dynamic and helped me hone my abilities coding in R and interpreting statistical results. I took a statistics class during my undergraduate studies but gained a much better understanding of analyses with Catherine's hands-on approach." Kayla Mladinich, PhD student

"I took Dr. Matassa’s Marine Biology course in the Fall of 2022. I personally was impressed with how innovative and diverse the content that she included in the class was. The laboratory experiments perfectly complemented the lecture period and helped me relate the information on the slides to real life situations. The ability to write and explore our own independent projects as well provided creative freedom that many other class labs seem to be lacking, and she did well to encourage critical thinking and exemplify how our experiments relate to real marine problems. Her inclusion of science communication in the curriculum was also a refreshing innovation to the lecture period, and something I had not experienced before in a STEM class." Greg Aniolek, undergraduate student

"Dr. Matassa coordinated an engaging field trip to Avery Point that was an exciting opportunity for students to expand their knowledge outside of the classroom. This opportunity included a tour of the Long Island Sound on a Project Oceanography research boat. While the tour was guided by two Project Oceanography educators, Dr. Matassa took every chance to communicate additional information that related to our classroom studies and energetically answered the questions that were raised. Dr. Matassa had something interesting and relevant to say about every species that we collected on the boat." Lukas Liebowitz, Senior Biology Major 2023

Meet Dennis Arbige

Posted on December 2, 2022December 2, 2022 by Hannes Baumann

By Ewaldo Leitao.

For the longest time, Marine Science students and staff have known who to email first with any worries or equipment malfunctions: Dennis Arbige. Until recently, Dennis was the manager of our Marine Sciences Building, but Dennis has been so much more than a manager. A man of many hats, Dennis not only knows the building like the back of his hand, but is also a talented electrical engineer who deals with a multitude of equipment (and their problems) allowing research to go as smoothly as possible – always with a smile on his face. Dennis has now retired, after 29 years of service to the department. We conducted an interview to learn more about his path, his past, and the changes he saw while working here.

Dennis, thank you so much for agreeing to do this interview. What has been your career path and how did you get here?

Dennis: It’s my pleasure! So, I grew up with Jacques Cousteau books’. I think the first book I read cover to cover was a Jacques Cousteau book because I had to read it in high school and it was only 70 pages, so I picked that. I was like “Oh, this is pretty interesting” how they do scuba and things like that. I then became interested in oceanography, while growing up near the ocean in Rhode Island. In high school I went to the Coast Guard to get money for college. I wanted to be a marine science technician in the Coast Guard. I wanted to go out and measure things like salinity and temperature, and I thought that would be pretty cool. But when I got to the Coast Guard they were like “well, we don’t do this anymore”. So I became an electronic technician.

EL: How did you come back to oceanography?

Dennis: During my four years in the Coast Guard, I was stationed all over the country. I was in Boston for a while, and they used to fly me over on a helicopter as an aid to navigation, working in lighthouses and things like that. This was about the time they were changing to automated lighthouses, so they would drop me off on these crazy little lighthouses all over Massachusetts and New Hampshire. I worked with a team, and installed things like fog detectors, etc. This was back in the early 80s. Every single installation had its challenges, because these were all old structures. It was super fun, these lighthouses were historical and cool. So I did that for four years, and when I left the Coast Guard I joined Rutgers University for an electrical engineering degree. I worked in New Jersey for a while, and while I was there I got interested in physical oceanography. There were people working on satellite stations and satellite dishes, for NASA and NOAA. So I became interested in what they were doing, remote sensing, sea surface temperature, and things like that. I started taking graduate courses in sea-water interaction, because they didn’t have any physical oceanography courses.

EL: So did you finish grad school and applied for jobs in oceanography?

Dennis: When I was still in grad school someone sent me a job application for a place called Ocean Surveys, in Old Saybrook in CT, I interviewed and I got the job. They did a lot of bathymetry and ocean sensing, near shore coastal stuff. So actually while I was in Ocean Surveys, I worked in the attic, with these slanted roofs. One day I heard this voice complaining, one of the customers kept bumping his head on the ceiling, and I was like “who is that guy?” My colleague told me this tall guy was from the UConn Marine Sciences department, his name was Frank Bohlen. So I ended up sending letters here to UConn, because I thought that “this place sounds like fun”. Actually Frank said: “hey, come on in, we can talk”. There was another wave of retirements at that time, in the 80s, so eventually, I got a job. I came here as an electronic research technician, 29 years ago. And I just never left.

EL: You jumped from industry back to academia sort of in a way. Was there something that appealed to you in this academic environment?

Dennis: Yes, it seemed that it was more fun, it had more variability. When I was here I worked as a scientific diver, and I also had some boating experience. Back in the day there were fewer people here, so I got to run small boats and to dive. I used to tell my wife: I would do this job for free, and she would reply “you better stop saying this”. It was fantastic, it was so much fun being here.

EL: You’ve seen a lot of changes here clearly, including this building being built. Can you talk a bit about how it was to experience that?

Dennis: When we got this building, that was a game changer. We went from the old building to this new building in 1999- late 2000s. The faculty got to design this building from the floor to ceiling. They basically got a piece of paper and were asked “what do you guys want?”. The faculty decided to have environmental chambers, a wet lab, a hydrodynamics lab, etc. And so it happened, and that was thanks to Dave Cooper who had a lot of influence, and he was a very smart guy. The new building put us on the map basically. A couple of years later we also went from the old RV UCONN to the RV Connecticut. When we got the floating docks, all of the facilities were consolidated in one location, here.

EL: In this building, would you consider that you’re a jack of all trades and master of all? Haha

Dennis: Master of none! That’s what you mean! OK, at this point I know a lot about this building. It’s funny to even talk to the trades people that we hired to come in here, I tell them: “pay attention to that because that will affect x, y and z, which will affect something else” and so on. It’s good to pass this knowledge along because some of this stuff will be hard if you don’t know about it. This is a complex building with a lot of systems, and they’re all interconnected, but it might not be clear why or how, so that’s something that I had to learn over time, by default, because you keep coming back inside.

EL: What was one of the happiest moments that you experienced in your career?

Dennis: The ROVs (remotely operated vehicles) were really fun! I’ve seen shipwrecks, I've seen crazy fish that I've never seen before. One time we put the ROV in the bottom, and the bottom looked like it was moving. It is all dark and you can’t see much, so as the ROV was approaching the bottom we saw that it was covered with shrimp. These shrimp were like 4-6 inches long! We were trying to find a place to land not to crush all these shrimp, because they were everywhere. We were off of North Carolina. The captain and the crew were all fishermen at some stage in their lives, and they were all going crazy, like “we never seen shrimp this thick before!”. It was one of the coolest things I’ve seen in my life.

EL: You’ve seen so many cohorts of grad students. Do you have any advice for younger students?

Dennis: Don’t be intimidated by the faculty and staff, because they're good people. If you have a question you should just go and ask. We all want you to succeed. Everybody will pretty much go out of their way to help you, to make sure that the students succeed. Faculty are just regular people. For example, my own kids used to play soccer with the faculty here, and they realized that the faculty are just regular people, which greatly helped them get through college. So don’t be afraid to approach them and ask them questions.

EL: And since you mentioned soccer…

Dennis: I know, I can’t go through a conversation without mentioning soccer, haha

EL: When did this soccer thing start here? For how long has it been going on? Were you the one who started this?

Dennis: It has been going on for some time and it actually started with the Coast Guard. Again, the Coast Guard used to have about 200 people working here. They had a huge presence once I first got here. I started playing with the Coast Guard people and when they eventually moved out, they kinda bequeathed their nets to me. Some pop up nets that they owned. At that time it was just me and some other people, including Jim O’Donnell. Soccer has been going on since the beginning.

EL: Who are you bequeathing it to now?

Dennis: Oh, to Michael.

EL: Do you have a retirement plan?

D: My wife has a list of projects that I need to do in the house. So I told her I would do it but I’d have to quit my job. But now I am like, alright. I have actually learned a lot from working in this building and working with the contractors, so that helps me a great deal on how to do these home projects.

EL: But soccer is here to stay, right?

D: Oh yes, for sure. When you do these extracurricular activities your work is still getting done, but it’s getting done in a less formal manner. On the field and on the court. It’s an amazing community.

“Harmony of Nature”: environmental data becomes music

Posted on December 2, 2022December 5, 2022 by Hannes Baumann

By Ewaldo Leitao.

Science communication has many flavors, kinds, and sounds. One way by which that can happen is when nature or science produce “noise” that can be channeled into sounds. That can be done using architecture (Sea Organ), or reinterpreting a field of science (Quantum Computer Music). Sometimes, this combination of sound and science can be a deliberate choice, creating music.

DMS student Molly James and musician Hea Youn Chung (Sophy) combined their expertises and interests to explore this intersection between science and music. Molly plays trombone in her free time at a community orchestra. Sophy is a professional pianist and teacher at Yewon Arts School (Seoul, South Korea) who did her Master of Music degree in Piano Performance at The Juilliard School. What initially joined these two at the dead of the pandemic was a mutual language assistance: Molly wanted to learn Korean, and Sophy, back in South Korea, wanted to continue practicing English.

And that’s how “Harmony of Nature” was born. A beautiful collaboration that converts natural phenomena into sounds through coding technology and expresses them in classical music. The project was funded by the Art & Tech program by Arts Council Korea. The data was collected using temperature loggers deployed in several sites across South Korea, along with freely available data from several spots. “I statistically analyzed this data and created multiple graphs using the open-source coding language Python. I shared them with Sophy and discussed the scientific interpretations. Together, we collaborated on what scientific aspects became what musical aspects.” said Molly, about the process of data collection and curation, prior to its translation into music.

“Like expressing human emotions through musical instruments, I have always wanted to express natural phenomena that we cannot see but can feel through sound. While envisioning this project, I focused on conveying natural phenomena through sound.” said Sophy. “For various expressions, I try to incorporate nuances such as shape and texture into the performance. In this project, the weight of the waves, the ebb and flow of the waves, the temperature changes, and the appearance of rain can be realized by various musical elements such as rhythm, dynamics, etc.”

The composition “One Week in Incheon” directly came from hourly air temperature measurements collected at a weather station by the Korean Meteorological Administration Incheon branch 112. Other data, such as wave height, flow and ebb tides, were also analyzed in order to compose some pieces. “During this performance, I hope you can feel changes in temperatures, drops of rain, speed of the winds, and height of the waves”, says Molly. More songs can be found on Spotify or AppleMusic.

Science needs to reach out to the public, informing in different, inventive, artistic ways. Art is powerful. Collaborations between science and art will thrive as each part can use their unique skills to result in beautiful projects, such as this one.

From microbes to whales: alumna Susan Smith on her career journey

Posted on December 2, 2022December 2, 2022 by Hannes Baumann

By Ewaldo Leitao.

Dr. Susan Smith graduated in December 2020, during the pandemic, from UConn Avery Point with Dr. George McManus. Her work focused on the ecology and molecular biology of marine ciliates (a kind of eukaryotic microzooplankton). During her PhD, Dr. Smith (Sue) discovered a new genus and species, published the first tintinnid ciliate genome, and formed lasting collaborations with some remarkable scientists. Susan is currently a research scientist at the Mystic Aquarium, where she studies the microbiome of beluga whales.

Q: Tell us a bit about the research you have done during your PhD.

Sue: While at UConn, I had the opportunity to take part in every facet of research—we would take a boat into the Atlantic and sample, bring them back to the lab and do microscopical and experimental work, and then use those same cultures for downstream genomic and genetic analyses. We would often do what my mentor would call “old world” microscope work, but would then take that same single cell and sequence its whole genome, all in the same lab. That kind of work that runs the full gamut of biological research is so rare today, but was such a valuable experience, and really allows you to understand your subject. I think the UConn Marine Sciences Department presents that opportunity far more than your average academic research setting, which is especially important for graduate students.

I actually had the good fortune of doing my B.Sc., M.S., PhD., and my Postdoc at UConn Avery Point (I’m a bit of a stubborn forever-student). I finished my postdoc two months ago (~1.5 years in) and immediately started my new position as a research scientist at Mystic Aquarium (luckily our labs are on the Avery Point campus so I get to keep my parking space and continue my path towards being a permanent fixture on campus).

Q: You’ve had the opportunity to teach during your postdoc. How was your teaching and postdoc experience?

Sue: I had the great pleasure of filling in for my (lifelong) mentor and graduate advisor Dr. George McManus when he was on sabbatical, which allowed me to teach his graduate course, Biological Oceanography. Teaching Bio Oce was a unique opportunity to work with higher level students that were serious about their graduate/educational career, and I valued and enjoyed that immensely. Luckily, even with my full time research position at Mystic Aquarium, I get to keep an appointment at UConn, and am scheduled to teach Marine Biodiversity and Conservation this spring semester (still seats left!). I’m extremely grateful to remain a part of both scientific communities.
Continuing a postdoc position in the same lab I did my PhD in allowed me to complete projects I was excited but over-zealous about during my PhD, and also allowed me the autonomy to ask new questions that were a little off track from the direction of the lab. Of course, there’s a major benefit in going to a different lab for your postdoc, especially if you want to change course on your research goals, but these days most PhDs end up doing two postdocs before finding a faculty position, so it’s something to consider.

Q: How did your previous work align with your current job in the aquarium? What are you doing now and what have you planned to do in the aquarium?

Sue: The postdoc project I was most enthusiastic about involved these unique ciliate species that live in cetacean blowholes (as a part of their natural, healthy microbiome). Admittedly, this project all started as a blatant excuse to collaborate with Mystic Aquarium and interact with the beluga whales there. I worked with some REU students (Research Experience for Undergraduate students) during the summers to investigate this more. The major benefit of this work was that it formed a collaboration with Dr. Tracy Romano (VP and Chief Scientist of Research at Mystic Aquarium). Today, my work at Mystic Aquarium largely surrounds host-associated microbiota. To be in a position where you have so many samples and project options that you can’t decide which grant proposal you’re most excited to write, is a great feeling. I also now contribute to weekly sampling efforts, so I get to hang out with whales every week—that’s pretty awesome too.
Part of my work today focuses on how the microbiome of a new animal host changes as they are introduced to a different host population. I also have some other fun projects going on, including genetic sexing of penguins, microbiome analyses in sea turtles, and stress-response tests in stranded seals. In general, my research is focused on answering these questions using non-invasive methods that not only avoid stressing the animals, but also can be used in the conservation of wild populations that are impossible to have close contact with

Q: What is the best part about working in the aquarium?

Sue: The best part about working in the aquarium are my colleagues. It quickly became clear that every veterinary staff member, animal husbandry professional, and researcher, are concerned with animal welfare above all else. Further, all Mystic Aquarium research has an application in the conservation of wild (often endangered) populations, and even non-invasive interactions with our animals are extremely regulated, as they should be. Additionally, and although lesser known, MA also puts an enormous amount of effort and resources into our stranding clinic, from seals to sea turtles, where the rapid recovery and release of these animals is of highest priority. These stranders also allow for some opportunistic (non-invasive) research sampling that can go a long way in identifying threats and diseases afflicting wild populations.

Q: Do you have any hobbies and/or activities you do in your free time?

Sue: This question would have worried me as a graduate student, since any energy put towards extracurricular activities would have been an unthinkable waste of time. However, I’m grateful that my current position is structured in a way that prioritizes a separation between work and home, which is something I didn’t realize I needed. Today, I’m happy to spend nights reading some old science fiction novel with a glass of red wine and dogs by my side. However, I also truly get pleasure from my work and will gladly spend a Saturday at a coffee shop with a (likely late) manuscript.
