Phytoplankton Levels Dropping

Released on September 11, 2014

New research led by NASA researchers has found populations of the microscopic marine plants, phytoplankton, have decreased in the Northern Hemisphere. An analysis using a NASA model in combination with ocean satellite data between 1998 and 2012, showed a 1% decrease of phytoplankton per year.
