Geochemistry of Organic Matter in the Ocean by Evgenii A. Romankevich

By Evgenii A. Romankevich

My paintings Geochemistry oj natural topic within the ocean first seemed in Russian in 1978. on the grounds that then a lot growth has been made within the exploration of assorted kinds of natural topic within the ocean: dissolved, colloidal, natural subject sus­ pended in debris and that contained in backside sediments and in interstitial waters. the right proof is located in hundreds and hundreds of articles and several other re­ view works, equivalent to Andersen (1977), Biogeochimie de [a matiere organique a ['interjace eau-sedimentmarine (1980), Duursma and Dawson (1981). a large amount of recent details has been acquired within the Soviet Union's medical associations at the composition and distribution in average waters and backside sediments of natural subject and its separate elements enjoying a vital function within the formation of the chemical and organic constitution of the sea and its productiveness, within the biogeochemistry of the weather and geochemistry of natural subject within the Earth's sedimentary conceal. The parts of exploration have improved over the last four-and-a-half years to embody many new, little-known areas, together with the Arctic seas. not like the 3 preceeding many years, the learn has been concerned with investigating the present types, the distribution and accumulation of natural topic in close to­ continental oceanic zones among land and sea, and in river estuaries.

1942, Redfield et al. 1963, Pytokowicz 1968). The other view presupposes that the supply of DOC, as well as of POC, to deep waters is negligible and their distribution is homogeneous (or nearly homogeneous) both in space and time (Menzel and Ryther 1970, Menzel 1974, MacKinnon 1981). The present chapter contains material on the determination of the C org content in approximately 1500 samples of sea water, performed by the methods of dry and/or wet burning developed in the Soviet Union (Skopintsev and Timofeyeva 1961, Liutsarev and Smetankin 1980).
