The Arabian Sea Process Study carried out on six cruises in 1995 provided observations that make possible the ground truthing of model estimates of k PAR and on deck productivity incubations with direct kPAR observations and in situ productivity incubations. THe Morel 1988 optical model did a good job of reproducing the observed values. Comparison of on deck and in situ depth profiles suggested that on deck incubators received more irradiance across the entire light gradient. This subsidy in E0 apparently came from efficient absorption of reflected light and low angle sunlight by small incubators. When depths were recalculated taking into account the irradiance subsidy, profiles of productivity as a function of depth determined by on deck incubations were essentially identical to in situ profiles. ©2005 Copyright SPIE - The International Society for Optical Engineering.
