Survey of New York surface water temperatures. Aerial infrared surveys of thermal discharges from electric generating stations into New York State waters. Final report

Quantitative measurements of cooling water discharges from electric generating plants into waterways are needed in order to evaluate the environmental impacts of these discharges. Aerial infrared sensing enables synoptic mapping of the temperature distribution over a large expanse of water surface. Application of the infrared method is illustrated by a series of flights made over the Hudson River. Thermal discharge plumes were measured at four power stations -- Albany, Danskammer Point, Indian Point and Lovett. Effects observed include tidal currents, local counter-currents, recirculation of discharged water, thermal striation, and mixing
