A return to his roots: SAFS undergrad conducts research in Hawai’i during HPP internship

Preparing a diverse group of first-year college students for the NOAA Ernest F. Hollings Scholarship is the Hollings Preparation Program (HPP) Internship, which includes a six-week paid research experience with one of NOAA’s many divisions. For Dash Dicksion, a SAFS undergrad now in his sophomore year, he got to return to his home island of Oahu during his HPP internship in the summer of 2024, working with the Ecosystem Sciences Division of NOAA’s Pacific Islands Fisheries Science Center. “I was born and raised on Oahu, where I grew up fishing and diving. I left Hawaiʻi for UW to pursue a top-notch education in a field I’ve been passionate about since childhood, but I still have deep ties to the place I call home,” Dash said. “I was excited to take this opportunity to return to my roots over summer and apply some of what I’ve learned on the mainland to real-word research!”

Learning about the HPP internship through an information session held at SAFS and referrals from previous academic mentors, Dash jumped at the chance to apply: “I saw this as an awesome opportunity to get an early jump into my desired career path and spend a summer learning from the best!” Based in Honolulu, Hawai’i, the State’s capital city, Dash’s internship focused on the biocultural and ecological aspects of fish larvae across Hawai’i Pae ‘Aina (the Hawaiian archipelago). “I worked under the guidance of an awesome team of mentors, and spent a lot of my time looking for, counting, and measuring fish larvae of interest under a microscope from preserved plankton sampled during previous research cruises,” Dash said.

During the lab portion of his internship, Dash also worked with data analysis and species distribution modeling in R, examining possible variable associations. “Interwoven with Western science work was input from native Hawaiian cultural practitioners and research into the traditional significance of fish species I was working with, their names, and the places where they come from”, Dash said. “I got to use that research to assist in developing nomenclature for larval fish in ʻŌlelo Hawaiʻi (the Hawaiian language). It was really awesome to see Hawaiian culture being appreciated and incorporated into modern research and discovery!”

Not only did Dash get to experience what day-to-day lab research consists of, he also spent 30 days at sea on board the Oscar Elton Sette, a 224ft research vessel named after the first director of the Honolulu Laboratory at U.S. Fish and Wildlife Service (now the NOAA Pacific Islands Fisheries Science Center). “I was afforded the very rare opportunity to join my mentor as part of a two-person science team sampling the Papahānaumokuākea Marine National Monument,” Dash shared. This World Heritage site encompasses 583,000 square miles of ocean and is the largest marine conservation area in the world. “My mentor and I “piggybacked” with the National Coral Reef Monitoring Program (NCRMP) divers to sample for larvae using Isaac-Kidd midwater trawls on the night shift. We aimed for five hour-long tows per night, working from offshore to as close as we could to each island within the monument,” Dash said.

In between the different stations visited for research, Dash and his mentor would do a quick sort of organisms that were visible to the naked eye, preserving the rest in jars of ethanol for sorting later on under the microscope. “Before and after every night of work, we would perform an oli, or chant to ask permission for sampling. Papahanaumokuākea is an especially sacred location in Hawaiian culture, and so it was crucial that we honored tradition when conducting our research.”

During transit days, activities including looking through photos, presenting research, watching preseason college football and fishing when 50 miles offshore of the monument. “I even got to dive at one point during the cruise, and it was amazing to see the range of life in the monument compared with what I was used to seeing in the main islands,” Dash said. As his first research cruise, Dash’s 30-day experience in the middle of the ocean was a unique one. “The constant movement takes a little for your body to get used to, but I was lucky I didn’t get seasick during the cruise,” Dash said. “The food was super good, the ship chefs are super talented and keep everyone well-fed for daily ops.” Compliments to the chef!

Aspiring to be a Fisheries Biologist or Management Specialist in the future, Dash described the internship as one which reaffirmed his desire to work in the world of fisheries sciences and management. “I would hope to eventually continue research on migratory pelagic predators like tuna and billfish, which especially piqued my curiosity during this project,” Dash said. Building on the foundational courses learned at SAFS was also a useful part of the HPP internship experience. “I’m glad for the exposure to a range of disciplines in the field of fisheries and marine science while studying at SAFS, and I intend to apply for more internship programs with NOAA as I continue my education,” he added.

“I would like to extend a huge mahalo to my mentors Justin Suca, Kanoe Morishige, Andrea Schmidt, Don Kobayashi, and Hauʻoli Lorenzo Elarco for their guidance and patience, as well as to everyone onboard the Sette during my first research cruise for making it a truly amazing experience!”


Working on Alaska pinniped projects during the SAFS-MML internship

Each year, UW students embark on the SAFS-NOAA Marine Mammal Laboratory internship program, spending a month or so working on projects related to marine mammals such as whale, seals, sea lions and porpoises. Project topics include marine mammal behavior, population dynamics, life history, migration patterns, distribution, and trends in abundance, with research taking place with the Marine Mammal Laboratory, a division of the  NOAA Alaska Fisheries Science Center (AFSC). This year during June to August, two students – Kenna Daily (ESRM) and Sofia Denkovski (Marine Biology) – split their time working on two Alaska pinniped projects: remote camera imagery and food habits.

Under the mentorship of Molly McCormley from AFSC, they helped assess the efficacy of NOAA’s machine learning model for detecting Steller sea lions in digital images. They manually reviewed over 21,000 images of Steller sea lions rookery sites in the Aleutian Islands, marking locations of branded sea lion individuals which will be compared to observations found by the machine learning model.

Known individuals are marked with a letter or symbol (indicates where they were born) and a unique number. In this example, Steller sea lion ~176 (behavior = Unknown) was identified in an image taken 26 May 2018 on Attu Island, Alaska.

While being mentored by Katie Luxa, also from AFSC, Kenna and Sofia processed ~300 frozen Steller sea lion and northern fur seal diet samples (i.e., scats and spews). The fish otoliths, bones, and squid beaks they recovered from samples are now ready to be identified by Marine Mammal Lab staff. They also helped prep northern fur seal vibrissae for stable isotope analysis and inventoried over 1,600 cephalopod specimens in the Lab’s food habits reference collection.

There were several different species present; the large V-shaped bone in the middle is a lower jaw from a wolffish (family Anarhichadidae).

In addition to their research tasks, Kenna and Sofia used this unique opportunity to connect with other MML and Alaska Fisheries Science Center researchers, setting up one-on-one meetings to learn more about their study animals and research projects. Their mentors reported that Kenna and Sofia did a fantastic job. They were enthusiastic, their work was impeccable, and they asked excellent questions, with both students being invited to stay on as part-time (<4 hrs/week) lab volunteers.
