Copernicus Sentinel-3 provides satellite observations of ocean and land colour, sea and land surface temperature, and sea surface topography. This record focuses on imagery and ocean-colour products available through the Copernicus Data Space Ecosystem. Spatial resolution varies by instrument and product; OLCI ocean-colour products are available at approximately 300 m (full resolution) and 1,200 m (reduced resolution).

The NOAA Coral Reef Watch Daily Global 5km Satellite Marine Heatwave Watch provides daily global monitoring of marine heatwaves at 5 km spatial resolution. Marine heatwaves are identified as periods of anomalously high sea surface temperature relative to a long-term daily temperature threshold and are classified according to their intensity. The product is derived from the NOAA Coral Reef Watch CoralTemp satellite sea surface temperature dataset and includes historical and near-real-time marine heatwave information from 1985 to the present.
