Climate Change Affects Bering Sea (Image 2)
Jackie Grebmeier, a National Science Foundation-funded researcher at the University of Tennessee, prepares sediment samples taken from arctic waters as part of the Western Shelf-Basin Interactions research project.
Physical changes such as rising air and seawater temperatures and decreasing seasonal ice cover appear to be the cause of a series of biological changes in the northern Bering Sea ecosystem. Changes such as these could have long-range and irreversible effects on the animals that live there and on the people who depend on them for their livelihoods.
A team of U.S. and Canadian researchers used data from long-term observations of physical properties and biological communities to conclude that previously documented physical changes in the Arctic in recent years are profoundly affecting Arctic life.
