Abstract
Since the pioneering work of the chemical compositions of the sea water, numerous quantitative analyses have been carried out for supplying the chemical composition table of the sea water. However, a few studies on the isotopic compositions of these elements in the ocean have been reported in the present time. Although the isotopic study of ocean has many difficulties, we can measure with high accuracy and probably represent very accurately the basic ratio for the chemical elements isotope ratio, at least for some elements. According to literatures, the stable isotopic compositions of D, Li, B, C, N, O, Mg, S, Cl, K, Ca, Fe, Br, Sr, Pb and also some natural radio isotope elements in the sea water are collected in this paper. This work is presented as an attempt to provide informations about the isotope geochemistry on the sea water.
