Measurements of sediment redox potential at 4 stations along a transect of the Parker River and near the mouth of the Rowley River, Newbury and Rowley, Massachusetts during 1993 and 1994.
Measurements of sediment redox potential at 4 stations along a transect of the Parker River and near the mouth of the Rowley River, Newbury and Rowley, Massachusetts during 1993 and 1994.
Measurements of bulk sediment carbon, nitrogen, chlorophyll a, phaeopigments and porosity 1993 - 2017 at a variety of sites in the Parker and Rowley Rivers, Newbury and Rowley Massachusetts.
In this dataset, we used a controlled flow-through reactor (FTR) experiment to test the role of nitrate as an electron acceptor, and its effect on organic matter decomposition and the associated microbial community in salt marsh sediments. Organic matter decomposition significantly increased in response to nitrate, even at sediment depths typically considered resistant to decomposition. The use of isotope tracers suggests this pattern was largely driven by stimulated denitrification.
