Abstract : From 1965 to 1967, absolute volume-scattering measurements for seawater (to depths of 700 m) were conducted in San Diego using an in situ light-scattering meter. Scattering from latex spheres was measured to determine if the instrument was properly calibrated. Volume-scattering functions for ocean waters varied considerably through the first 100 m, but were uniform beyond this depth. Deep water was found to be clear, while scattering and attenuation -- discounting motes -- approached data for distilled water. In addition, the size and amount of scattering matter, inferred from the scattering function, decreased with depth. Attempts to measure light scattering in regions of high acoustical scattering were not successful. (Author)
