During the cruises No 17 and 22 of the German research vessel „Meteor“, 45 water samples were taken at 4 stations in the central part of the Mediterranean Sea. Mass spectrometrical analyses showed that systematic, but time variable changes of the oxygen isotope ratios occur. Deep water samples (T> 500 m) have a ± constant isotopic composition of d18O = +1.79‰ (SMOW) and a Chlorinity of 21.399‰. These data are discussed with respect to paleotemperature determinations.
