Brenda Holladay is a fisheries oceanographer with the University of Alaska Fairbanks, where she received a B.S. in biology and M.S. in fisheries oceanography. She has studied distribution, abundance, community structure, and trophic ecology of larval and demersal fishes throughout Alaskan waters for 23 years, and for the past eight years has focused on Arctic fishes of the Chukchi and Beaufort seas. Holladay is co-principal investigator of the fisheries ecology research on RUSALCA, with principal investigator Dr. Brenda Norcross, also a fisheries oceanographer of Institute of Marine Science, and senior contributor and ichthyoplankton scientist Morgan Busby of the NOAA National Marine Fisheries Service. Holladay leads the onboard fisheries ecology team that includes Kelly Walker and Dr. J. Andres Lopez.
The fisheries ecology project continues the time series community assessment that was established at sites sampled during 2004 and 2009 RUSLACA cruises by documenting all life stages of fishes, including ichthyoplankton, juvenile, and adult demersal fishes. Fishes have rarely been studied in the Chukchi Sea. The fish ecology project RUSALCA cruises establishes baseline information on abundance and age structure needed to assess potential changes in fish communities as climate change.
Dr. Russ Hopcroft is a Professor at the University of Alaska's Institute of Marine Science in Fairbanks (UAF). He grew up fascinated by aquatic life (and Jacques Cousteau specials) and pursued this fascination throughout his education. Dr. Hopcroft received his Master’s degree in 1988 and his Ph.D. in 1997 from the University of Guelph, Ontario, Canada. The focus of his graduate research was on plankton ecology in the tropical waters surrounding Jamaica. From 1997 to 1999, he was a post-doctoral fellow at the Monterey Bay Aquarium Research Institute, where he was heavily involved in the use of remotely operated vehicles and traditional oceanographic surveys to study the oceans. He pursues a broad array of research interests, concentrating on the composition, production, and energy flow of the planktonic trophic levels that ultimately shape the structure of all marine communities.
Since joining UAF in 2000, his focus has shifted to Arctic and subarctic planktonic communities with an emphasis on Alaskan waters. Much of his lab’s activity focuses on understanding the linkage between climate and zooplankton communities. In addition to traditional emphasis on crustaceans zooplankton (copepods and euphausiids), he also works on the broad array of soft-bodied zooplankton groups such as jellyfish, the larvacean pelagic tunicates, and most pelagic snails (pteropods and heteropods). He has served on the steering committee of several Census of Marine Life projects, including the Arctic Ocean Biodiversity project, the Census of Antarctic marine Life, and the global Census of Marine Zooplankton. He is increasingly recognized for his images of live zooplankton that are widely distributed in the media and on the web.
Katrin Iken is an Associate Professor in Marine Biology at the University of Alaska Fairbanks. She is fascinated by the polar regions, having worked in Antarctic waters between 1996 and 2001 and in the Arctic since 2002. So far, she has participated in about 22 research cruises to the Antarctic, the Arctic and the Deep-Sea. Her background is in benthic ecology, especially trophic interactions and food web studies. Dr. Iken will be part of the epibenthic and food web team on board the Khromov (with Dr. Bluhm and her student Bell) and within the RUSALCA project. She will collect benthic and pelagic invertebrates and study how they form the food web and how this differs across different regions of the study area.

of how biology, geography, and history shape the distribution of
Arve Lynghammar is a Ph.D. candidate working at the Department of Arctic and Marine Biology in Tromsø, Norway. His research interests are taxonomy, population genetics, and ecology of Arctic skate species. Normally, he is fishing in the Atlantic Ocean, such as Greenland, Svalbard, Jan Mayen, and the Barents Sea. On this cruise, he is involved in DNA barcoding of Arctic fishes, as well as improving current fish identification guides in cooperation with Catherine Mecklenburg.
Catherine W. Mecklenburg
For more than 35 years, Catherine (Kitty) Mecklenburg has been studying and writing about the marine fishes of Alaska and adjacent Arctic seas. Curatorial support for her collections is provided by the California Academy of Sciences in San Francisco, where she is a Research Associate with the Department of Ichthyology. Her home base is Point Stephens Research, just north of Juneau, Alaska, where she and her physiologist-GIS expert husband and coauthor, Tony, live and conduct research under contracts with state and federal agencies. A major accomplishment with her as lead author (collaborators T.A. Mecklenburg and L.K. Thorsteinson) was the monograph Fishes of Alaska,published in 2002. She is the author or coauthor of several taxonomic reviews in the series California Academy of Sciences Annotated Checklists of Fishes. Her most recent significant paper as lead author is a circumpolar review using original data on species presence and DNA barcoding, as well as the recent literature, of the taxonomy and distribution of Arctic marine fishes (in Marine Biodiversity with P.R. Møller and D. Steinke, 2011). Primarily with the support of the RUSALCA program, she has been working on an atlas and identification guide tentatively titled, Fishes of the northern Bering Sea, East Siberian, Chukchi, and Beaufort Seas and adjacent deep waters of the Arctic Ocean. She has participated in U.S. Fish and Wildlife Service cruises to the Semidi Islands, Gulf of Alaska; Norton Sound, Bering Sea; Pribilof Islands, Bering Sea; the central Aleutian Islands; and a NOAA National Marine Fisheries Service fish survey in the Chukchi Sea in 2007. She participated in the RUSALCA interdisciplinary cruises of 2004 and 2009, and her sampling supplies have been sent and await her in Nome for the 2012 cruise. While resampling at continental shelf stations is important to maintain a series of samples over time to assess change, for the 2012 cruise she is particularly eager to reach the new, unexplored northernmost stations where the most interesting discoveries are likely to be made.
