Algorithms for Ocean-Bottom Albedo Determination from In-Water Natural-Light Measurements

Abstract

A method for determining the ocean-bottom optical albedo Rb from in-water upward and downward irradiance measurements at a shallow site is presented, tested, and compared with a more familiar approach that requires additional measurements at a nearby deep-water site. Also presented are two new algorithms for estimating Rb from measurements of the downward irradiance and vertically upward radiance. All methods performed well in numerical situations at depths at which the influence of the bottom on the light field was significant.
