This report summarizes progress from September 1977 through August 1978 on a series of marine chemical and geochemical investigations involving both laboratory studies and field studies off the coast of Washington. Most field work has been in Puget Sound or on the Washington continental shelf, slope and the submarine canyons indenting the shelf north of the Columbia River. Our aim is to provide basic data required to characterize underlying chemical and physical processes and their rates which control the distributions, concentrations and ultimate fate of some of the potentially hazardous agents associated with fossil fuel and/or nuclear power production or transportation. The main lines of investigation are: (1) field studies of the uptake and transport by zooplankton fecal pellets of /sup 210/Po, /sup 210/Pb and other trace inorganic and organic constituents in a well studied part of Puget Sound; (2) studies of the behavior of /sup 210/Po and /sup 210/Pb in sediments off the coast of Washington and the application of the /sup 210/Pb determinations in sediment cores to determine sediment accumulation rates for the past 100 years, the depth of the surface mixed layer, and a mixing coefficient for the surface sediments; (3) studies of the uptake and transfer of /sup 210/Po, /sup 210/Pb and related elements in the well-defined surf zone ecosystem at Copalis Beach, Washington; and (4) investigations of aliphatic and aromatic hydrocarbons in some of the same samples of organisms and sediment cores whose accumulation histories for the past 100 years we have determined with the lead-210 technique.
