Coastal zone color scanner

The Coastal Zone Color Scanner (CZCS) is a satellite instrument that captures images of Earth's coastal waters by measuring the color of the ocean surface. Different colors indicate various things like algae blooms, sediment levels, and water quality. This data helps scientists monitor environmental health, understand biological productivity, and track changes in marine ecosystems, especially in coastal areas where ecosystems are most sensitive and economically important. CZCS was an important tool in remote sensing, providing valuable insights into oceanic and coastal processes from space.
