He enjoys Alaska, with its unique nature and the easy access to fascinating marine environments. His contribution to Arctic Exploration will focus on life at the interfaces of the pack ice floes in the Arctic Ocean. They will search for marine animals living related to sea ice on its surface, in its interior and on the bottom of the floes. For that purpose, they will collect material with ice corers. Divers will support them by providing video observations and animal collections from these regions.

Dr Mette NielsonMette Nielson
Graduate Student

Originally from Connecticut, Mette Nielson received a B.S. in Marine Biology at Oregon State University in Corvallis. Before starting a graduate program in Oregon, she took what was to be a month long trip to visit friends in Alaska. The month turned into several months, and she finally returned to Oregon a year later to collect her belongings and officially move to Anchorage. She was drawn to Alaska for its mountains and outdoor opportunities and currently lives in Fairbanks where she is a graduate student. Her research takes place on coastal sea ice near Barrow, Alaska where she is using a stable isotope approach to investigate the coastal Arctic food web and the effects of the changing ice environment on local fauna. Her focus is ice-associated amphipods that act as a link between food produced within the ice and higher trophic levels, including fish and seals. Through her work she hopes to gain insight into how the coastal food web will respond to shorter periods of ice cover, and how this might affect subsistence opportunities for native Alaskans living on the Arctic coast. When she isn't in the field, Ms. Nielson enjoys skiing, biking, climbing, and exploring Alaska's vast outdoors. During the Ocean Exploration Cruise she will be part of the sea ice team.

Dean StockwellDean Stockwell
Research Assistant Professor (Oceanography),
Institute of Marine Science, School of Fisheries and Ocean Sciences,
University of Alaska

Dean Stockwell is a biological oceanographer who has been studying polar waters (both Arctic and Antarctic) for more than 25 years. From ice camps to drill ships and from icebreakers to submarines, Dean has worked with marine phytoplankton in extreme environments. He has been at UAF seven years as a research professor and served at NSF as Associate Program Manager for Antarctic Biology and Medicine Program. As a phytoplankton taxonomist, Dean is primarily interested in what species of phytoplankton are present. How these plankton communities respond (both growth and competition) to light conditions, inorganic nutrients, grazing and advection is a primary interest. The Arctic environment presents phytoplankton communities with extremes in temperature, salinity, light and nutrients, all of which influence local phytoplankton assemblages. During the Arctic Exploration studies, however, Dean will assist in primary production estimates and biomass determinations.

Sarah ThorntonSarah Thornton
Research Technician
Institute of Marine Science
University of Alaska, Fairbanks

Since beginning her oceanography career 13 years ago, Sarah Thornton has been involved in many investigations in the Arctic, Chukchi and Bering Seas, and the Gulf of Alaska. Currently working as a research technician for Dr. Terry Whitledge, she spends about 1/4 of the year at sea. Much of the time, she acts as a mooring technician, deploying moored nutrient and other oceanographic sensors. Other times, she participates in water sampling for dissolved nutrients (“plant food”) and algal concentrations and conducts primary productivity experiments. She received a B.Sc. from the University of British Columbia in 1994 and an M.S. from the University of Alaska Fairbanks in 2003.

Terry WhitledgeTerry Whitledge
Chemical and Biological Oceanographer
University of Alaska, Fairbanks

Terry Whitledge is a chemical/biological oceanographer who has been studying the Bering Sea and Arctic Ocean for more than 25 years with respect to nutrient dynamics and responses by the plankton communities. The requirement of light and inorganic nutrients by phytoplankton in order to grow often controls the food available to the higher tropic levels such as zooplankton and fishes. The complex interactions of winds, changing temperatures, ice cover, and freshwater input from the land create a physical environment that is nearly always changing and causes the growth of plankton to respond to a wide range of environmental conditions. The object of the Arctic Exploration studies is to document some of the nutrient and light effects on phytoplankton growth under the ice and in open water where it occurs. Analysis of the salinity and temperature along with nutrient and light conditions will allow for future predictions of the effects of global climate change in the Arctic as temperatures increase and ice cover diminishes.

Marsh YoungbluthMarsh Youngbluth
Senior Scientist
Division of Marine Science, Harbor Branch Oceanographic Institution

Dr. Marsh Youngbluth is a Senior Scientist with the Division of Marine Science at Harbor Branch Oceanographic Institution. He received his undergraduate degree from Portland State University, a Master's degree from the University of Hawaii (cleaning symbiosis among coral reef fishes), and his PhD from Stanford University (diel migrations by krill in coastal and oceanic regimes). His research projects in the field of biological oceanography involve investigations of the biodiversity, behavior and ecology of mesopelagic zooplankton. Recent studies have focused on the predatory habits and metabolic rates of coronate medusae (fjords of Norway) and physonect siphonophores (basins in Gulf of Maine and deep canyons along Georges Bank). The roles of midwater tunicates (appendicularians) as mediators of particle transport have also been examined. Dr. Youngbluth has worked as a visiting scientist at the University of Umeå, Sweden, University of Bergen, Norway, Japanese Center for Promotion of Science, Japan and National Center for Scientific Research, France. He has served as a Program Director (NSF Biological Oceanography Program and NOAA National Undersea Research Program). Dr. Youngbluth pioneered the development of crewed (Johnson Sea-Link) and robotic (Aglantha) submersibles for water column research. A firm believer of employing "the right tools for the job," he continues to utilize novel technologies for ongoing explorations of the mid-ocean realm. Read more about water column ecology exit icon.
