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.

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.
Spartina is grown in experimental elevation planters placed in draining ponds on the salt marsh platform. The planters are constructed from PVC pipes of varying lengths. All of the PVC pipes are open at the bottom, and flush to the mudflat surface of the pond, resulting in the tops of the pipes being situated at various relative elevations within the tidal range. Plants growing in the shorter PVC pipes are flooded for a longer duration of each tidal cycle than plants growing in the taller PVC pipes. The growth response of S.

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.
Aboveground plant biomass and density is determined non-destructively during the growing season at a Spartina alterniflora-dominated salt marsh on the Rowley River within the Plum Island Ecosystems (PIE) LTER site.
Biomass of Spartina alterniflora was collected at various locations within the Plum Island Sound estuary. Samples were collected during July 2018. Only Spartina alterniflora was collected. To collect biomass, 25 X 25 cm quadrats were placed over the plants. Aboveground biomass was clipped to soil surface. Biomass was dried in the lab in a drying oven until a constant weight was reached, and then weighed. Biomass values were then convertedto grams of dry weight per square meter (g/m2).

Salt and brackish marsh vegetation distribution was documented using cover classes (modified Braun-Blanquet) on individual plots along 9 transects in the Plum Island Estuary. The plots were also surveyed for elevation rel mNAVD88 using RTK GPS . The plots and transects had been surveyed for vegetation and elevation in 2001. The re-survey is designed to monitor changes in species composition and marsh elevation across a broad spatial scale over the previous 20 years. The survey will also serve as a baseline for future marsh monitoring work with UAVs.
We selected 9 transects from a set of 40 marsh surveys conducted in 2000 and 2001 to use as a baseline for monitoring changes in species composition and marsh elevation across a broad spatial scale in the Plum Island Estuary. In the early surveys, latitude, longitude and elevation, as well as salt and brackish marsh vegetation composition were documented using cover classes on individual plots. Results from those surveys have been compiled here.
