A new multiyear study has shown for the first time how changes in ocean temperature affect a key species of phytoplankton. The study tracked levels of Synechococcus -- a tiny bacterium common in marine ecosystems -- near the coast of Massachusetts over a 13-year period. As ocean temperatures increased during that time, annual blooms of Synechococcus occurred up to four weeks earlier than usual because cells divide faster in warmer conditions, the study found.
Tropical Depression Sarika made landfall early on Oct. 19 as NASA-NOAA's Suomi NPP satellite passed overhead and provided an image of the storm.
NASA satellite data provided a look at Super Typhoon Haima in visible and infrared light to show the extent and strength of the storm. The Visible Infrared Imaging Radiometer Suite instrument aboard the NASA-NOAA Suomi NPP satellite provided an infrared image of Haima on Oct. 18 and a visible image on Oct. 19.
Supertyphoon Haima continues to move toward the Philippines and NASA-NOAA's Suomi NPP satellite provided a visible image of the storm that revealed a clear eye.
As Tropical Storm Sarika moved over Hainan Island, China, NASA-NOAA's Suomi NPP satellite captured a visible picture of the storm as it made a direct hit. On Oct. 18 at 1:55 a.m. EDT (0555 UTC) the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard NASA-NOAA's Suomi NPP satellite provided a visible-light image of the storm. The image showed the center of circulation covered by clouds.
Tropical Storm Nicole was becoming extra-tropical when the NASA-NOAA Suomi NPP satellite passed over it from space and captured a visible picture of the storm. By Oct. 18, Nicole was a post-tropical storm and the National Hurricane Center or NHC issued their final advisory on the system.
Tiny robots have been helping researchers study how climate change affects biodiversity. Developed by Northeastern University scientist Brian Helmuth, the 'robomussels' have the shape, size, and color of actual mussels, with miniature built-in sensors that track temperatures inside the mussel beds.
NASA-NOAA's Suomi NPP satellite provided a visible look at Powerful Typhoon Haima as it continued moving to the west-northwest through the Northwestern Pacific Ocean. Haima is forecast to affect the northern Philippines where it is known as Lawin.
NASA-NOAA's Suomi NPP satellite provided a visible look at Typhoon Sarika as it was poised for its second of three expected landfalls. When the satellite passed over Sarika it was in the South China Sea.
On Oct. 17, Hurricane Nicole has been active for almost two weeks. Nicole was still a hurricane when the GPM core observatory satellite flew over on Oct. 17.
