Russian American Long term Census of the Arctic
Meet the Team
Teacher - Betty Carvellas
Betty Carvellas retired in 2007 after teaching science for 39 years at the middle and high school levels. She was a founding member of the National Academies Teacher Advisory Council (TAC) and currently serves as the Teacher Leader for the TAC. Her interests include interdisciplinary teaching, connecting “school” science to the real world, and bringing the practice of science into the classroom. Throughout her career, she traveled extensively on her own and with students. Her professional service includes work at the local, state and national levels. She served as co-chair of the education committee and was a member of the executive board of the Council of Scientific Society Presidents and is a past president of the National Association of Biology Teachers. Included among her awards are the Outstanding Science Teacher-Vermont (1981), Presidential Award for Excellence in Mathematics and Science Teaching (1984), and a Christa McAuliffe fellowship. Betty has embarked on a number of collaborative expeditions such as PolarTREC, and has participated in seven research expeditions in the Arctic. In 2008, she was designated a lifetime National Associate of the National Research Council of the National Academies.
Researcher - Jacqueline Grebmeier
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.
Where are They?
The team of U.S. and Russian scientist will travel on the Russian research vessel (R/V) Professor Khromov in order to conduct sampling in both the Russian and U.S. waters of the Bering and Chukchi Seas.
What are they Doing?
These seas and the life within them are biologically rich and are thought to be particularly sensitive to global climate change because they are in areas where steep thermohaline and nutrient gradients in the ocean coincide with steep thermal gradients in the atmosphere. The Bering Strait acts as the only Pacific gateway into and out of the Arctic Ocean and as such is critical for the flux of heat between the Arctic and the rest of the world. One of the overall goals of the entire project is to monitor the flux of fresh and salt water in the region and to establish benchmark information about the distribution and migration patterns of the biologically rich life in these seas. Dr. Grebmeier's research on this final cruise of the project is particularly focused on benthic biological communities and their associated sediment chemistry.
