This project analyzes the coupling between motion of water and phytoplankton productivity and related processes 

 in the water column of the Southeastern Continental Shelf. Research is conducted in the inner shelf and involves 

 analysis of rates of (1) biological and chemical processes important to the carbon and nitrogen cycle and (2) cross- 

 shelf removal of material from the inner shore.

Recent studies in nearshore regions of the South Atlantic Bight indicate that sediments are an important temporary 

 and'or permanent repository for trace elements supplied by rivers and tidal exchange with inshore and offshore 

 waters. We are determining the sources of trace elements and their distribution in nearshore sediments as well as 

 the dominant sedimentary phases that influence their fate. Stable depositional areas and their rates of sedimenta- 

 tion are being evaluated. We are analyzing (1) changes in chemical composition caused by exchange of nearshore 

 and estuarine water, (2) the rate of trace metal and nutrient loss from the water column to nearshore sediments, (3) 

 the importance of living and nonliving particles in controlling the transformation and the fate of trace metals, and 

 (4) the importance of cross-shelf removal of particles.
