1. NASA – Sea-viewing Wide Field-of-view Sensor (SeaWiFS)
Chase, Derek, Laurel, Tim

2. Purpose and Vision
The purpose of SeaWiFS data is to examine oceanic factors that affect global change and to assess the oceans' role in the global carbon cycle, as well as other biogeochemical cycles, through a comprehensive research program.
Can monitor ocean production and phytoplankton process, ocean influences on climate processes (heat storage and aerosol formation ) and the cycles of carbon, sulfur, and nitrogen.
Developed by ORBIMAGE Inc. and NASA
