SeaWiFS stands for Sea-viewing Wide Field-of-view Sensor. It is an optical remote sensing sensor on the OrbView-2 satellite, a part of the SeaWiFs project run by NASA. The purpose of the project is to provide quantitative data on global ocean bio-optical properties to the Earth science community. The instrument was specifically designed to monitor ocean water quality and ecological characteristics such as chlorophyll-a concentration and water clarity. For this purpose, the sensor records information in the following optical bands:
Band Wavelength 1 402-422 nm 2 433-453 nm 3 480-500 nm 4 500-520 nm 5 545-565 nm 6 660-680 nm 7 745-785 nm 8 845-885 nmSeaWiFS began scientific operations on 18 September 1997. The sensor resolution is approximately 1.1 km.
