“…Dissolved fatty acids in all samples (n = 10) were dominated by saturated fatty acids (88%), mainly 16:0 and 18:0, which contributed 37% and 29%, respectively (Figure 4). Previous studies have also shown that saturated fatty acids were predominant in the DOM pool [Kattner et al, 1983;Berdie, 1995]. This might be due to more rapid abiotic and biotic degradation of polyunsaturated fatty acids (PUFA) and monounsaturated fatty acids (MUFA), com- pared to their saturated counterparts [Canuel and Martens, 1996;Harvey and Macko, 1997].…”

[1] The distribution of dissolved organic carbon (DOC) in the western Arctic Ocean is greatly influenced by conservative riverine DOC flux into the northern Bering Sea, Bering Strait and Beaufort Sea, as indicated by an inverse correlation with salinity. Based on the relations between DOC, salinity and seawater temperature, several water masses could be identified. These included riverine water, ice-melt water, surface mixed water, cold and saline shelf water, and Atlantic Ocean water. High concentrations of chlorophyll a and DOC were found in some parcels of dense shelf water in Barrow Canyon. In addition, labile DOC compounds, such as polyunsaturated fatty acids (PUFA), were found in the dense shelf water, suggesting the dense shelf water contains a product (marine organic matter) of the biological CO 2 pump.

“…The distribution of dissolved organic compounds is controlled by diffusive processes superimposed by an inlet and outlet flow. Particle-associated transport is dominated by aggregation and horizontal sedimentation (e.g., Berdie et al 1995). On the contrary river systems are characterized by a much higher dynamic of the flow regime affecting also the mobility and appearance of organic compounds.…”

Organic matter appears in all compartments of the hydrosphere of both natural and more and more anthropogenic origin. Aquatic organic matter exhibits a high structural diversity and corresponding physicochemical properties. Marine and terrestrial surface water bodies including their corresponding sediments as well as groundwater are affected by natural compounds of autochthonous origin from aquatic species, in particular from phyto-and zooplankton, and allochthonous material from terrestrial biota. Anthropogenic pollutants are released to aquatic ecosystems mainly as the result of municipal, industrial, and agricultural
