Arctic Ocean: Climate change is flooding the remote north with light - and new species

The crew of the  U.S. Coast Guard Cutter Healy, in the midst of their ICESCAPE mission, retrieves supplies for some mid-mission fixes dropped by parachute from a C-130 in the Arctic Ocean in this July 12, 2011 NASA handout photo obtained by Reuters June 11, 2011. Scientists punched through the sea ice to find waters richer in phytoplankton than any other region on earth.  Phytoplankton, the base component of the marine food chain, were thought to grow in the Arctic Ocean only after sea ice had retreated for the summer. Scientists now think that the thinning Arctic ice is allowing sunlight to reach the waters under the sea ice, catalyzing the plant blooms where they had never been observed.
