“…The areal, diurnal, and seasonal distribution of sea-surface temperatures presented herein are similar to those deduced from the previous, scattered measurements of the Dead Sea (Stanhill, 1981).

Twenty-seven thermal survey cruises made over 4 years, and 1 year of remotely sensed surface temperatures were used to examine areal, diurnal, seasonal and interannual changes in the temperature of the Dead Sea and in its heat storage.The satellite data, corrected for a cold bias attributed to the anomalous depth and turbidity of the Dead Sea's atmosphere, indicate a very small areal variation in sea-surface temperature (SST), typically less than 0.3"C over two-thirds of the sea surface. The maximum value measured, 4YC, was at night in mid-winter. Below-surface temperatures showed much larger areal variations caused by the shallower thermocline in the north of the sea. This variability was the reason for the large number of measurements required to assess accurately seasonal changes in heat storage.Diurnal variations in SST were at their maximum, 3"C, in May, and at their minimum, 0,3"C, in December. During the summer, diurnal differences were clearly evident at a depth of 5 m, with some evidence that a layer twice as deep could be affected.Seasonal variation in SST was not symmetrical. From mid-March to early July, surface temperature increased uniformly at 0.10"C day-', between mid-September and mid-November the cooling rate, 0.13"C day-I , was also constant. In January and February, and July and August, SST was almost constant, with day-to-day changes less than 0.01"C. The seasonal amplitude in SST was 11.5"C at the surface, 9.6"C at 25 m depth, halved at 35 m, and was reduced to one-tenth, 1.4"C, at 50 and 75 m.No significant interannual changes in surface temperature were found since the mid-winter rise of 3-4°C that occurred 30 years ago. During the last decade the maximum seasonal depth of the thermocline has progressively deepened to 30 m, and below this depth an increase in the temperature of the deeper waters is evident. Possible sources of this heating are discussed.Seasonal changes in the heat storage were in phase with those in the surface temperature, with maximum values of 9.1 MJ m-' dayy' in June and -8.7 MJ m-' day-' in December. The heat budget (intra-annual range) of the Dead Sea. 1.16 GJ m*, is one of the highest reported in the literature, although less than that expected from its depth and radiation balance. The sea's heat content increased by an average of 224 MJ m-' year-' during the 4 years of this study; the large year-to-year variation in this heating was negatively correlated with the fall in sea level.
