Regions Exhibiting Decreased Phytoplankton Levels and Increased Sea Surface Temperatures
Released on October 8, 2009
Throughout most of Earth's ocean, as the surface layer of the ocean warms, the water becomes less dense and forms a cap, rather than mixing down to allow cooler, nutrient-rich water to well up. Over time, areas with less mixing show reduced productivity and less phytoplankton. This data visualization highlights regions where a strong correlation between high sea surface temperatures and decreased phytoplankton productivity occurred from 1997-2006. For nearly a decade, the Sea-viewing Wide Field-of-View Sensor (SeaWiFS) has been making global observations of phytoplankton productivity. On December 6, 2006, NASA-funded scientists announced that warming sea surface temperatures over the past decade have caused a global decline in phytoplankton productivity.
