Marine geochemistry / Морская геохимия

The fundamental question underlying marine geochemistry is 'How do the oceans work as a chemical system?' At present, that question cannot be fully answered. However, the past two decades or so have seen a number of 'quantum leaps' in our understanding of some aspects of marine geochemistry. Three principal factors have made these leaps possible: (a) advances in sampling and analytical techniques; (b) the development of theoretical concepts; and (c) the setting up of large-scale international oceanographic programmes (e.g. DSDP, MANOP, HEBBLE, GEOSECS, TTO, VERTEX, GOFS, SEAREX), which have extended the marine geochemistry database to a global ocean scale. <...>
