To examine the relationship between lipid-degrading enzyme activities and lipid composition in estuarine sediments, lipase activities and fatty acids in surface sediments at dierent stations along the Altamaha River were determined during a high discharge period. Freshwater sandy sediments from upstream stations were characterized by low organic carbon and… (More)
We studied the biochemical degradation of organic matter comprising marine diatom, land grass, and salt marsh plant in estuarine ecosystems in two laboratory microcosms consisting of estuarine sediments and coastal seawater. The materials were incubated separately and together under controlled oxic and anoxic conditions to test effects of co-metabolism and… (More)
Lipid compositions and compound-specific 13 C ratios of high-molecular-weight dissolved organic matter (HMW-DOM) in the Middle-Atlantic-Bight varied with water depth, implying that the origins of HMW-DOM at different layers of the ocean may differ.
