MOBY: afloat in Hawaii - News Briefs
A Marine Optical Buoy (MOBY) off the coast of Lanai in the Hawaiian Islands is the centerpiece of the primary ocean measurement site for calibrating satellite-born ocean color sensors. The project, which is being led by NOAA with the support of NASA as well, includes team members from the Moss Landing Marine Laboratory, the University of Miami, San Diego State University, and NIST. Measurements from this ground-truth site are being used to calibrate satellites operated by the United States, Japan, France, and Germany that are designed to infer what is going on at the ocean surface.
The ocean buoy has specialized, optical radiation instruments that measure both the incident solar flux and the water-leaving radiance at sea level and at depths of 1 m, 5 m, 9 m, and 12 m. The instrumentation features two imaging spectrometers, onboard calibration sources, and eight light collectors multiplexed with fiber optical cables.
