SUMMARY Since the launch of NASA’s TERRA satellite, the Marine Optical Characterization Experiment

(MOCE) Team has continued to acquire and provide at-sea observations for MODIS initialization and calibration tasks. The Marine Optical Buoy (MOBY) system has been acquiring optical and basic meteorological observations coincident with TERRA’s overpasses in support of the Moderate Resolution Imaging Spectrometer’s (MODIS) ocean color mission.. During this period, the team conducted eight field campaigns in Hawaii in support of the MOBY project. These cruises, designated MOBY-L63 through MOBY-L69, serviced the MOBY215, MOBY216 and MOBY217 systems. Marine Optical Characterization Experiment (MOCE-8) was carried out in Hawaii in February- March 2001 in conjunction with the MOBY swap out to provide additional initialization data for the MODIS side b electronics configuration. A match up MOBY and MOCE database was produced for the side b coincident overpasses for the 31 October 2000 through 11 March 2001 time period. This data base is being utilized as the initialization data set for the iterative process of testing and evaluating the MODIS ocean spectral band vicarious calibration in both the Goddard and University of Miami code versions. The results of these comparisons are forwarded to Miami for their evaluations. During this period the bio-optical products were reformulated utilizing an improved Nimbus-
