A method of measuring laser beam extinction in the atmosphere over the ocean has been devised and satisfactorily demonstrated. An attempt was made to correlate the observed values with existing meteorological conditions. The apparatus consisted of equipment, already being used for scintillation measurements, modified by the addition of a source intensity monitor. Several calibration trials and three over-water experiments were conducted. A value on the order of 0.0005meters was found for the extinction coefficient in clear weather.
