  • This dataset provides optical level 0 ocean colour data. The SeaWiFS instrument was launched by Orbital Sciences Corporation on the OrbView-2 (a.k.a. SeaStar) satellite in August 1997, and collected data from September 1997 until the end of mission in December 2010. SeaWiFS had 8 spectral bands from 412 to 865 nm. It collected global data at 4 km resolution, and local data (limited on board storage and direct broadcast) at 1 km. The mission and sensor were optimised for ocean colour measurements, with a local noon (descending) equator crossing time orbit, fore-and-aft tilt capability, full dynamic range, and low polarisation sensitivity. The data were transferred to CEDA when the Dundee Satellite Receiving Station NERC Earth Observation Data Acquisition and Analysis Service (NEODAAS Dundee node) facility was closed to continue the long term archive.
