| Abstract: | The sulphur isotopic composition of ocean water sulphate was determined, using the SF6 method, for samples from various depths of the Geosecs Stations II and 3 and for a single Pacific Ocean surface sample. The total spread in values obtained is less than that found in previous studies and is consistent with the experimental precision except for one Geosecs II sample which has an unusually low δ34S value. The mean value, + 20.99%., is markedly different from the hitherto accepted value of +20.0%.. The difference is attributed to the greater accuracy obtained when SF6 rather than SO2 is used as the sample gas for sulphur isotope analysis. |
