Ocean color sensors measure the spectral distribution of reflected sunlight, which can be used to infer the contents of the water, including chlorophyll a concentrations, a proxy for phytoplankton biomass. Phytoplankton are the base of the marine food web and are critical regulators of key biogeochemical processes. To provide weekly, monthly and annual chlorophyll concentrations of the U.S. East Coast onGoing pointOfContact Hyde, Kimberly (401) 782-3226 28 Tarzwell Drive Narragansett RI 02882 USA kimberly.hyde@noaa.gov pointOfContact custodian Hyde, Kimberly (401) 782-3226 28 Tarzwell Drive Narragansett RI 02882 USA kimberly.hyde@noaa.gov custodian Chlorophyll, phytoplankton, remote sensing theme Northeast and Southeast U.S. Continental Shelf Large Marine Ecosystems place DOC/NOAA/NMFS/NEFSC > Northeast Fisheries Science Center, National Marine Fisheries Service, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2017-04-24 publication 8.5 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.
