Ocean Biology, 1997-2006 (IMAGE)
Caption
Scientists now have nearly a decade's worth of data showing the cycle of plant life in the Earth's oceans. From space, the "ocean color" satellites measure the ocean's biology as plant productivity. In this visualization, high plant productivity is represented in green, while areas of low productivity remain blue. Data were collected by the Sea-viewing Wide Field-of-view Sensor (SeaWiFS).
