Progress on a series of marine chemical and geochemical investigations involving both laboratory studies and field studies off the coast of Washington are summarized. Most of the field work has been on the Washington continental shelf, slope, and the submarine canyons indenting the shelf north of the Columbia River. The 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 nuclear power production or transportation. The studies have followed several main lines of investigation which are in various stages of completion: (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; and (3) 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 /sup 210/Pb technique.
