| Abstract: | A recent unconsolidated marine sediment collected from the Aleutian basin of the Bering Sea (57 02.9 N, 17657.4W) was separated into eight size fractions by sieving. Each of the fractions was analyzed for density, organic carbon, total nitrogen and various organic materials. A detailed analysis of the correlation of organic carbon and total nitrogen to the mean diameter of the particles separated, indicated that the surface sorption processes of organic matter were the determinative factor controlling the concentration of organic carbon and total nitrogen on silt and clay particles of the sediments.Selective sorption of amino acids was found to occur in the 8–20 and 5–8 m. fractions of the sediment. This is assumed to be due to their surface active property. |
