International Polar Day - Polar Oceans
March 18th, 2009 marks the eighth quarterly International Polar Day, this time focusing on Polar Oceans. This includes marine biodiversity, physical oceanography and more. Activities will occur throughout the last two weeks of March 2009.
Cooling and sinking processes in polar oceans, and circulation of polar waters throughout the global deep ocean exert a powerful control on the Earth’s climate. The polar oceans also play very important roles in the global carbon cycle, removing carbon dioxide from the atmosphere through chemical and biological processes. Polar oceans support globally-important fisheries and ice-dependent polar birds and mammals, including polar bears in the Arctic and penguins in the Antarctic. All of these important polar ocean functions have a critical relationship with sea ice; changes in the integrated polar ocean - ice system thus have far-reaching impacts.
