Characterization of organic matter in sediments from Gulf of Alaska, Bering and Beaufort seas

摘要: The paraffin fraction of the high molecular weight hydrocarbons have been identified from sediment samples Eastern Gulf Alaska and Bering Sea. In general it has shown that: concentrations total in surface sediments both areas, with exception one sample near Pribilof Canyon, is low compared to recent marine other environments; appear be derived a mixture terrigenous sources. Sea, source predominates, while Alaska, contribution mainr sources approximately equal. A series n-alkanes unresolved n-C21 n-23 range occurs some Sea many Alaska. these may either petroleum or unidentified organisms. Sediments head Canyon contain hydrocarbons. This contrast most which no indications addition. Several analyzed seem indicate contribution.
