The Marine Optical BuoY (MOBY) is a NOAA funded project to provide vicarious
calibration of ocean color satellites (SeaWiFS, MODIS, and VIIRS).
MOBY is an autonomous optical buoy which is moored off the island of Lanai in
Hawaii. The system was designed for measuring sunlight incident on and
scattered out of the ocean.
These measurements are provided in near real time for the vicarious
calibration procedures conducted by ocean color scientists.
