Abstract : The study was conducted to determine the feasibility of detecting plankton over various sea states using absorption spectroscopy with visible light. A qualitative analysis of their presence and a quantitative analysis of their concentrations were to be determined. Over a limited range of 100 feet or slightly more, it appears that a white light source with a collimated light beam should have adequate sensitivity even in daylight. During darkness or with certain improvements, it should be possible to improve the range. The equipment was not field tested, so positive proof of plankton detection and concentration measurement was not obtainable. (Author)
