Paper Abstract

The vertical distribution of the photosynthetically available irradiance (Epar) in the ocean has long been of interest as a measure of the penetration of light energy available to phytoplankton for photosynthesis. Recently, the vertical distribution of the photosynthetically usable irradiance (Epur) has become recognized as a better measure of the energy used for photosynthesis by phytoplankton in the ocean. Our interests in the modeling and prediction of the primary productivity of the ocean have led to a model for the vertical distribution of these quantities based on data available from remote platforms. In this paper, we describe a model for the vertical distributions of both the photosynthetically available and usable irradiance in the ocean for Jerlov (1976) Case I waters, and describe the behavior of these quantities from the results of the model. The model assumes that the vertical distribution of pigment (chlorophyll a) is known over the depth of the euphotic zone.
