Dr. Dana Scakett


Mackenzie is working toward a doctoral degree in Marine Biology. She developed a passion for deep-sea biology while working at Whitman College on adaptations to high pressure. She has participated in research cruises to the Kermadec and New Hebrides Trenches in the Southern Pacific Ocean. After earning her Bachelor’s degree in Biology and German Studies in 2012, Mackenzie taught eighth and ninth grade English as a Fulbright Scholar in Bremen, Germany. Her current research interests center on the age, growth, and adaptations of the planet’s deepest-living fishes.



Astrid Leitner is currently pursuing a PhD in biological oceanography and graduated from the University of California Santa Cruz with a BS in Earth and Planetary Sciences with an Ocean Sciences Concentration and a BS in Marine Biology. In her undergraduate studies she worked on coastal ecology in the kelp forests and the rocky intertidal at her home institution as well as deep sea biology through a submarine canyon project at Hatfield Marine Science Center. At UH manoa she is working on the ABYSSLINE project, developing an ecological baseline for the abyssal ecosystem in the Clarion-Clipperton fracture zone in light of recent mining claims. Additionally, she is continuing her work on abrupt topographies especially seamount ecosystems. She has just started the oceanography program in August and has already been on two research cruises with many more to come.

Phoebe Woodworth-Jefcoats is a Ph.D. student examining the potential impacts of climate change on North Pacific fisheries.  Prior to her studies at UH, she earned a B.S. in meteorology from the University of Oklahoma and a M.S. in meteorology and physical oceanography from the University of Miami.  She then went on to work for the National Oceanic and Atmospheric Administration (NOAA), first as an officer in their Commissioned Corps and now as a civilian research oceanographer at NOAA’s Pacific Islands Fisheries Science Center in Honolulu.  Phoebe’s research interests include investigating how organisms make use of their environment and using food web models to predict the impacts of both climate change and fishing on North Pacific ecosystems.

Data Manager


Virginia has been involved in deep-water snapper research as a member of the Bottomfish Project since 1997 when she assisted in the population genetic study of ehu and onaga. In 2000, she joined the hatchery team in researching methods to culture snappers, primarily opakapaka, for stock enhancement. Since 2006, Virginia has analyzed underwater video and maintained the database for the project.

Dr. Jeffrey Drazen




Jeff received his PhD from Scripps Institution of Oceanography in 2000 working under Dr. Ken Smith on the feeding ecology of bathyal and abyssal fishes. After graduation he backpacked around the world with his wife for a year hitting all the continents including Antarctica.  Afterwards, he took a postdoctoral position at the Monterey Bay Aquarium Research Institute under Drs. Jim Barry and Bruce Robison working on a diversity of projects most involving the use or remotely operated vehicles (ROVs).  Jeff joined the Oceanography faculty at University of Hawaii, Manoa in 2004 where he continues to pursue many aspects of deep-sea fish ecology.

Kristen is pursuing a M.S. in biological oceanography.  She graduated with a B.S. in Aquatics and Fisheries Science from the State University of New York College of Environmental Science and Forestry, where she studied the feeding behavior of Caribbean corals using bulk stable carbon and nitrogen isotope analysis for her undergraduate thesis.  Kristen has ample field experience working on coral reefs on several Caribbean islands including Dominica, Bocas del Toro, Panama, and the Dominican Republic.  After her undergrad, she lived for a year in the Dominican Republic working on restoration of the endangered Caribbean coral Acropora cervicornis.  Here at UH Kristen is returning to work with stable isotopes.  For her Master’s thesis she will be using compound specific nitrogen isotope analysis of amino acids to study the relative importance of micronekton, such as the world’s most abundant vertebrates, Cyclothone, or bristlemouth fishes, to the mesopelagic food-web.

Kristen Gloeckler

Kazia is a junior at Carleton College in Northfield, MN, although she originally hails from Los Angeles. She has spent the past two summers at the UH Manoa researching the habitat preferences of onaga and most particularly the scales at which these deep water snappers associate with their surroundings. Kazia is excited to be participating in her first research cruise this summer, a month-long trip to the equatorial regions south of Hawaii. In the long run, she hopes to pursue a doctoral degree in some field of biological oceanography.
