Ocean Color Experiment (OCE)

NSSDCA ID: 1981-111A-05

Mission Name: STS 2/OSTA 1
Principal Investigator:Dr. Hongsuk H. Kim


The Ocean Color Experiment (OCE) was designed to demonstrate the ability to locate plankton or chlorophyll concentrations and identify circulation features by mapping color patterns in the ocean. The OCE instrument was a modified version of a NASA high-altitude aircraft sensor known as the U-2-borne ocean color scanner. The instrument was also similar to the coastal zone color scanner (CZCS) on the Nimbus 7 satellite. It consisted of two main modules: the scanner and the electronics. The scanner was mounted on the experiment pallet shelf, and the electronics were coupled to a cold plate on the pallet deck. The rotating mirror on the OCE instrument scanned plus or minus 45 deg from nadir across the direction of flight with a ground resolution of 3 km. The scanner operated in eight spectral intervals: 486 nm (blue), 518 nm, 553 nm (green), 585 nm, 621 nm, 655 nm (red), 685 nm, and 787 nm (near-infrared). The OCE experiment operated successfully and overall image quality and spectral information were excellent. The instrument acquired approximately 20 to 30 minutes of cloud-free data.
