Hydrocarbons: natural distribution and dynamics on the Alaskan outer continental shelf
Results of hydrocarbon analyses of biota, water, sediment and seston are reported and discussed. In general these analyses show that the Alaskan OCS environments are free of petroleum at the present time. Petrogenic hydrocarbons were detected in intertidal sediments of the Beaufort Sea. It is not yet known to what extent, if at all, anthropogenic sources contribute to these hydrocarbons. Efforts to understand and quantify processes by which hydrocarbons in the water column are transported to the benthic environment are described. The two such processes investigated are the association of hydrocarbons and suspended sediments and the scavenging and sedimenting of hydrocarbon droplets by zooplankton. It appears that at least for the conditions of south central Alaska the formet process is not highly efficient. Results about the latter process is not highly effecient. Results about the latter process are not yet available. Brief descriptions of recently begun site specific studies are presented.
