Summary
This lecture provides an overview of climate and biological changes in Pacific-influenced Arctic marine ecosystems. It reviews and examines the major contributing factors to these changes, including changing conditions of sea ice, freshwater input, and the alteration of marine ecosystems. Examples of these factors are provided to illustrate the potential impacts that will have broad-reaching implications for long-term ecosystem structures. This lecture also reviews the progress of various programs undertaken during recent years (i.e. Bering Sea Research Program, Canada's Three Oceans, the Russian/US Long-term Census of the Arctic Ocean, and the Western Arctic Shelf-Basin Interactions) which have provided insights into the key processes influencing ecosystem function and change in the northern Bering and Chukchi shelf regions. Data sets from these programs are included in this L&O e-Lecture, in the context of biological response to sea ice changes in the Pacific Arctic region, with accompanying discussion by the L&O e-Lecture author.

Dr. Jacqueline Grebmeier is a Research Professor at the Chesapeake Biological Laboratory University of Maryland Center for Environmental Science. Her research is focused on pelagic-benthic coupling on continental shelves in the Arctic, benthic ecology, invertebrate zoology, contaminant distributions, and high latitude oceanography. She has participated in over 40 oceanographic cruises on both US and foreign ships, many as Chief Scientist. She is the current U.S. Delegate and Vice-President of the International Arctic Science Committee and member of the Arctic Ocean Sciences Board.

This ASLO Arctic lecture was based on an invited plenary presentation Dr. Grebmeier gave at the 2004 ASLO Oceans meeting entitled "Biological Implications of Arctic Change to Carbon Shelf-Basin Exchange."
