Joint U.S.-Russian Oceanographic Research Expedition to the Bering and Chukchi Seas

On August 24, 2004, scientists led by oceanographer Dr. Terry Whitledge, University of Alaska Fairbanks (UAF), returned to Nome, Alaska, from a three-week, joint U.S.-Russian oceanographic research expedition to the Bering and Chukchi Seas. Ten American, two Canadian, two German, a Korean and 20 Russian scientists conducted an array of studies on the region's physical, chemical and biological oceanography.

The expedition was the first in the Russian-American Long Term Census of the Arctic, and was sponsored by the National Oceanic and Atmospheric Administration (NOAA) and the Russian Academy of Sciences (RAS).

The team examined a wide range of topics covering water column and benthic surveys, fish distribution, nutrient and current fluxes, methane distribution, and seafloor processes.

Studies relevant to the Arctic Ocean Census of Marine Life focused on planktonic, benthic and fish communities: Dr. Russ Hopcroft (UAF) with Dr. Ksenia Kosobokova (Shirshov Institute of Oceanology, RAS, Moskow) conducted a census of the zooplankton at the sampled stations. Drs. Ken Dunton (Univ. of Texas at Austin), Katrin Iken, and Bodil Bluhm (both UAF) and Drs. Boris Sirenko, Sergej Gagaev (Zoological Institute (ZIN), RAS, St. Petersburg,) with Dr. Jackie Grebmeier (University of Tennessee at Knoxville) investigated the benthic epifauna and infauna, respectively. The team conducting fish studies included Drs. Kitty Mecklemburg (Univ. of California, Santa Barbara), David Stein (Smithsonian Institution), Boris Sheiko (ZIN), Natalia Chernova (ZIN), Brenda Norcross and Brenda Holladay (both UAF).

Scientists traveled aboard the 71.6-meter (235-foot) research vessel Professor Khromov, operated by the Far East Hydrometeorological Institute in Vladivostok, Russia. Over 50 stations were sampled and will be jointly analyzed by the Russian-American teams, contributing to the Russian-American Long Term Census of the Arctic and the Arctic Ocean Census of Marine Life.
