NASA's OceanColor Web is supported by the Ocean Biology Processing Group (OBPG) at NASA's Goddard Space Flight Center. Our responsibilities include the collection, processing, calibration, validation, archive and distribution of ocean-related products from a large number of operational, satellite-based remote-sensing missions providing ocean color, sea surface temperature and sea surface salinity data to the international research community since 1996.

Ocean Color Feature

Gulf of Alaska

In the summertime, meltwater from Alaska's glaciers washes into the Gulf of Alaska carrying a suspended load of rock flour with it. The glacial scrapings supply the micro-nutrient, iron, to the gulf. Mesoscale eddies help distribute the iron to the offshore waters where it promotes the growth of phytoplankton, particularly diatoms.
