SOME OBSERVATIONS OF THE DIURNAL HEAT WAVE IN THE OCEAN’
The diurnal heat wave was observed over several days at a station in the subtropical North Atlantic Occnn. Measurements were made every 30 min using an in situ tempera-ture-salinity-depth recorder; the isotherms were plotted (to an accuracy O.OlC) at 2-m depth intervals. For a day of average conditi...

| Summary: | The diurnal heat wave was observed over several days at a station in the subtropical North Atlantic Occnn. Measurements were made every 30 min using an in situ tempera-ture-salinity-depth recorder; the isotherms were plotted (to an accuracy O.OlC) at 2-m depth intervals. For a day of average conditions, the maximum penetration of the dis-ccrnible heat wave was to about 30 m, but throughout the cycle approximately 80 % of the gain of heat in the water column was confined to the top 14 m. Estimates of the coefficient of vertical eddy diffusion were made at several depths, and for the top 4 m the daily values varied between 93 cm’/scc and 432 cm”/sec. |
