June 2, 2026 — The new Coastal Northeast U.S. satellite imagery supports bloom tracking in the Gulf of Maine and coastal waters off New York and New Jersey. These products provide satellite-based information to help partners better understand potential bloom conditions across a broad coastal region.
NCCOS is also adding a separate demonstration high-resolution Great Lakes satellite imagery to include Maumee Bay, OH, Apostle Islands, WI, and Saint Louis River, MN. These products use Sentinel-2 MultiSpectral Instrument imagery, which provides higher spatial resolution (20m) than existing Sentinel-3 Ocean and Land Colour Instrument products (300m). The higher-resolution imagery can support monitoring in smaller or more complex water bodies where finer-scale satellite observations may be useful.
