Short vodcasts feature current research and the scientists involved. Four Climate Watch vodcasts, including ones on Changing Biomes and Permafrost, and a series on research at Lake El'Gypytgyn in Siberia involving coring through 3.5 million years of lake sediments to reconstruct Arctic paleo-environments were still in production on April, 2011.
The extent and thickness of Arctic sea ice has diminished significantly during the first decade of the 21rst century, reaching a record low summer extent in 2007. Changes in sea ice have major impacts on Arctic marine ecosystems and on the fish and wildlife species upon which many Alaskan coastal communities and Native cultures depend.
