SeaWiFS was NASA's ocean-color science program built around the Sea-viewing Wide Field-of-view Sensor carried by the commercial OrbView-2 spacecraft, originally called SeaStar. The instrument repeatedly mapped chlorophyll and other indicators of marine biology so researchers could study ocean productivity, phytoplankton, harmful algal blooms, and the ocean's role in the global carbon cycle.
