Aboveground biomass is determined non-destructively during the growing season at a Typha-dominated brackish marsh on the Parker River within the Plum Island Ecosystems (PIE) LTER site.
Porewater samples from a Spartina alterniflora-dominated salt marsh on the Rowley River in the Plum Island Ecosystem (PIE) LTER site were analyzed for ammonium, phosphate, sulfide and salinity concentrations.
Porewater samples from a Spartina patens-dominated salt marsh on the Rowley River in the Plum Island Ecosystem (PIE) LTER site were analyzed for ammonium, phosphate, sulfide and chloride concentrations.
A Surface Elevation Table (SET) is used to measure changes in the elevation of the marsh surface at three long term marsh fertilization experimental research sites. The sites include one Typha-dominated brackish marsh, one Spartina alterniflora-dominated salt marsh, and one S. patens-dominated salt marsh. Sites are located on the Rowley and upper Parker Rivers in the Plum Island Ecosystem (PIE) LTER site.

Aboveground biomass is determined non-destructively at permanent plots in a Spartina alterniflora-dominated salt marsh in North Inlet, Georgetown, SC. There are five sites. Two sites are low marsh; three sites are high marsh. One site in the high marsh is fertilized with nitrogen and phosphorus.
Annual productivity is determined from aboveground biomass data in a Spartina alterniflora-dominated salt marsh plots on the Rowley River within the Plum Island Ecosystems (PIE) LTER site. Aboveground biomass is determined non-destructively.

Nutrient concentrations from porewater samples at marsh sites in the Plum Island Ecosystems (PIE) LTER site. There are three long term marsh fertilization experimental research sites. The fertilization sites include one Typha-dominated brackish marsh, one Spartina alterniflora-dominated salt marsh, one S. patens-dominated salt marsh on the Rowley and upper Parker Rivers and two non-fertilized marsh sites on the Parker River National Wildlife Refuge.
Nutrient concentrations from permanent porewater samplers in a Spartina alterniflora-dominated salt marsh in North Inlet, Georgetown, SC. There are six sites. Two sites are low marsh; four are high marsh. One site in the high marsh is fertilized with nitrogen and phosphorus. One site in the high marsh is located in a dieback. Sampling at the dieback site occurred from 2006-2010.
Marsh sediment porewater nutrient concentrations [NH4+, NO3-, DOC, TDN, H2S] and salinity are reported from Spartina sp. and Typha sp. sites along the Parker and Rowley Rivers, MA. Porewater peeper poles are used for collection and the poles are located in the vicinity of the marsh water table sites for the Railroad, Typha, Shad and Nelson sites.
Porewater nutrient concentration data [SRP, NH4+, S-2, Cl-] from several sites along the Rowley and Parker Rivers, MA and Wells NEER, ME.
Plant heights are measured during the growing season in permanent plots at a Spartina alterniflora-dominated salt marsh on the Rowley River within the Plum Island Ecosystems (PIE) LTER site. Plant heights are coverted to plant weight using an algorithm for a non-destructive measure of aboveground plant biomass.
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.
We measured diel fluctuations in surface water chemistry of two high marsh ponds in July 2016. The ponds are shallow and experience day-night swings in oxygen concentrations, from super-saturation to anoxia. Our goal was to characterize changes in geochemical properties and dissolved organic carbon concentrations that accompany wide swings in oxygen concentrations. These data provide information about the responsiveness of microbial communities and how the dominance of redox-sensitive metabolisms changes over short time scales (e.g., hours) to feed back on pond water chemistry.
