What Are They Doing?

The research team studied the impacts of predators on the main benthic prey species in the Northern Bering Sea. Main predators of benthic organisms include spectacled eiders, groundfish, snow crabs, sea stars, and gastropods. As ice cover declines and groundwater temperatures increase in the Bering Sea, the ranges of mobile benthic predators such as crabs and groundfish may increase and thus affect food availability for other predators such as the spectacled eider. The team used trawls, corers and nets to extract sediment and water samples from the sea floor in order to inventory the benthic population and document any changes occurring within the marine food web.

Where Are They?

The team traveled on the USCGC Healy in the Bering Sea, which lies to the west of Alaska and the east of Russia. The Healy sampled the biologically diverse waters between St. Lawrence Island and St. Matthew Island with a secondary study area located between St. Lawrence Island and Little Diomede Island in the Bering Strait.

Wow! What a week! I'm here at the Westmark Hotel, in Fairbanks, Alaska are in the middle of our 2010 Orientation and ShareFair.  It's been very exciting to meet all the new teachers and see how they are adjusting to the fact that they will soon be heading out to the Polar Regions.  It's been a…
Most people’s vision of "scientists” is men in white lab coats. On the Healy, the only people wearing white coats are the "seal team”—a group of four men and one woman from the National Marine Mammals Laboratory, based in Seattle, Washington. They are a very fun group to be around but then again,…
Science aboard the Healy is not just random. With Chief Scientist, Jackie Grebmeier, the research plan takes shape and becomes a coordinated effort so that everyone aboard the ship can conduct his or her research. A well-planned effort is needed since the ship is expensive to operate (I heard…
Sometime late Friday afternoon, a man in an orange suit just "suddenly” appeared at the Gambell lodge.  Vince, the helicopter manager for the Healy, was there to pick several of us from Gambell and whisk us away to the Healy – someplace offshore about 50 miles south of the community.  I was going…

Jacqueline Grebmeier - Researcher
University of Maryland Center for Environmental Sciences

Jacqueline Grebmeier is currently a research professor at the University of Maryland Center for Environmental Sciences (Chesapeake Biological Laboratory). Over the last 25 years, her arctic field research program has focused on such topics as understanding biological productivity in arctic waters and sediments, and documenting longer-term trends in ecosystem health of arctic continental shelves, including studying the importance of bottom dwelling organisms to higher levels of the arctic food web, such as walrus, gray whale, and diving sea ducks. Dr. Grebmeier has served on numerous advisory committees and research boards, and has coordinated and participated in numerous international research projects. Dr. Grebmeier has been involved with numerous teacher experience and education programs in the Arctic, including hosting TREC teachers in 2004, 2006 and PolarTREC in 2007.
