Owens1, Jeffrey C. Cornwell1 1Horn Point Laboratory, University of Maryland Center for Environmental Science Here, we present small core incubations for the measurement of sediment-water gas and solute exchange. These will provide reliable measurements of sediment-water exchange that assess the role of sediment in influencing biological and biogeochemical processes in aquatic ecosystems.
