Thanks to a NASA-sponsored expedition to the Arctic Ocean in the summers of 2010 and 2011, scientists have found an area underneath the sea ice, which is richer in microscopic marine plants, essential to all sea life, than any other ocean region on the Earth.
The expedition, called ICESCAPE (Impacts of Climate on EcoSystems and Chemistry of the Arctic Pacific Environment), explored the waters in the Beaufort and Chukchi seas along Alaska’s western and northern coasts using optical technologies. According to scientists, the findings would help reveal a new consequence of the Arctic’s warming climate and provide a vital clue to understanding the impacts of a changing climate and environment on the Arctic Ocean and its ecology.
