Abstract

THE Atlantis II Deep is a pool of hot saline brine at the bottom of the central rift in the Red Sea (Fig. 1). Since its discovery in 1965 (ref. 1) it has undergone repeated detailed investigations2,3. A permanent increase of temperature has been reported by many workers4–8 and was interpreted as the result of the injection of hot brine to the system. The temperature of the inflowing brine was estimated to range between 110 and 210 °C (refs 6, 8). We have reinvestigated (after five years) the Atlantis II Deep on board RV Sonne. We report here the results of temperature measurements which were carried out in November 1977.
