Optical Properties of the North Atlantic Ocean at Argus Island

摘要

The attenuation coefficient, the relative irradiance, and the volume scattering function were measured at 5300A independently and nearly simultaneously as a function of depth and time of day. Volume scattering function data were extrapolated to extreme angles, and the total scattering coefficients were computed by machine integration for 81 samples. Assuming a radiance distribution function, the absorption coefficient was approximated from relative irradiance data. The experimentally determined coefficients are compared with each other to discover the degree of consistency with theoretical predictions. Attempts are made to correlate the vertical distributions of these coefficients with profiles of temperature and biological and particulate concentrations which were measured concurrently. (Author)
