R/CBT-12

Direct measurements and biogeochemical controls of sediment-water flux

Principal Investigator: 

Jeffrey C. Cornwell

Start/End Year: 

1991 to 1993

Institution: 

Chesapeake Biological Laboratory, University of Maryland Center for Environmental Science

Co-Principal investigator: 

Walter R. Boynton, Chesapeake Biological Laboratory, University of Maryland Center for Environmental Science; David J. Burdige, Old Dominion University

Description: 

The objectives of this research are to reliably measure the direct fluxes of trace elements across the sediment-water interface of field-collected cores, measure temporal and spatial variability of such fluxes and determine the importance of Mn, Fe and S redox cycling on trace element production and consumption. This project will determine whether the recycling of metals within surficial sediments has an important impact on water column metal concentrations.
