Orbit data |
SeaWiFS (abbreviation for Sea-viewing Wide Field-of-view Sensor ) was the only scientific instrument on board the GeoEye satellite Orbview-2 (also known as SeaStar ), a private satellite in the Orbview program. SeaWiFS was the follow-up experiment to the Coastal Zone Color Scanner on board Nimbus 7 . The instrument was put into orbit on August 1, 1997 with a Pegasus rocket and began scientific operations on September 18 of the same year. The SeaWiFS project was part of the NASA program Earth Observing System . The satellite was lost in mid-2011.
The task of the instrument was to collect large amounts of data on the bio-optical properties of the oceans . Barely visible differences in the color of the oceans indicate different types and concentrations of phytoplankton .
The sensor recorded image data in the following wavelengths:
tape | wavelength |
---|---|
1 | 402-422 nm |
2 | 433-453 nm |
3 | 480-500 nm |
4th | 500-520 nm |
5 | 545-565 nm |
6th | 660-680 nm |
7th | 745-785 nm |
8th | 845-885 nm |
