Measurements of sediment porewater nutrient, sulfide, pH, and alkalinity, 1993 -2004, at a variety of sites and salinities throughout the Plum Island Sound estuary.
Measurements of sediment porewater nutrient, sulfide, pH, and alkalinity, 1993 -2004, at a variety of sites and salinities throughout the Plum Island Sound estuary.
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.
Comparison of NH4+ freely available in sediment porewater to NH4+ exchangeable from sediments, and the variabilty with porewater salinity as it changes with season and along a transect of the Parker River estuary.
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.
Rates of benthic metabolism and nutrient cycling in the Parker and Rowley Rivers of the Plum Island Sound estuary. Measurements include those conducted at two sites in the Parker River in Spring (high river discharge) and Fall (low discharge) for long-term monitoring, also at other sites throughout the estuary over a variety of seasons and salinities.
