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

Lake Erie

At the end of winter the ice is nearly all gone from Lake Erie, and growing phytoplankton populations are revealed mingling with suspended sediments in this relatively shallow Great Lake.

The above Aqua/MODIS image was collected on March 12, 2021. Click on it to get a larger version that includes all of the Great Lakes.
