Between 2 and 21 September 1959, approximately 900 bathythermograph observations BTs were obtained at Ocean Weather Station ECHO 35 deg N, 48 deg W. In addition, incoming radiation from sun and sky and reflected radiation from the sea surface were recorded. By grouping the BT data according to cloud amount, mean hourly temperatures were obtained. Estimates of heat absorption, evaporation and changes in horizontal heat content advection for clear, partly cloudy, and cloudy skies were derived from these mean temperatures. The ocean was assumed to be neither gaining nor losing heat during this season of the year. For clear skies, evaporative heat loss exceeded long wave back radiation heat loss for cloudy skies, condensation resulted in a net gain of heat. Hourly mean temperatures and temperature gradients are presented. Surface temperature was changed about 0.1 deg F by evaporative heat flux and a comparable amount by horizontal heat flux. Author
