We deployed an eddy covariance system to measure ecosystem-atmosphere exchange of CO2 above a high marsh system (Spartina patens, short Spartina alterniflora) located on the Parker River Wildlife Refuge in marshes of Plum Island Sound, Rowley MA. This data represents the growing season CO2 exchange (May-October) in 2012.

Multi-year transects, beginning in 1995, of the Parker River Plum Island Sound Estuary conducted at dawn and dusk, containing dissolved oxygen, conductivity, temperature, percent saturation, pH, DIC and pCO2 measurements. Differences between dawn and dusk measurements can be used to determine the water metabolism and corresponding estimates of gross primary production, total system respiration and net ecosystem production.
Water chemistry including nutrient concentrations for various forms of N, P, C, as well as suspended sediments and light extinction coefficients, was determined from bi-annual nutrient transects along the Plum Island Sound estuary from the Parker River Dam to the mouth of the sound. Grab samples were taken at 11 sites along a 24 km transect from the mouth of the estuary to as near the dam at the head of the estuary as poosible. These samples have generally been collected in Spring and Fall and are done in conjunction with metabolism transects measuring dissolved oxygen levels. The Spring

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.

We deployed an eddy covariance system to measure ecosystem-atmosphere exchange of CO2 above a high marsh system (Spartina patens, short Spartina alterniflora) located on the Parker River Wildlife Refuge in marshes of Plum Island Sound, Rowley MA. The system is located near a higher elevation rock outcroppingprotected area which allows the tower set up to remain during the Winter as it is protected from ice flows. The data represents CO2 exchange for all 12 months of 2013.

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).
Aboveground biomass is determined non-destructively at permanent, high marsh control (non-fertilized) plots in a Spartina alterniflora-dominated salt marsh on Nelson Island near Stackyard Rd in the Parker River NWR within the Plum Island Ecosystem (PIE) LTER site, MA.
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.
Water chemistry including nutrient concentrations for various forms of N, P, C, as well as suspended sediments and light extinction coefficients, are determined from bi-annual or tri-annual nutrient transects from the mouth of the Rowely River estuary to near its head about 6 km upstream. Three sets of grab samples and sonde measurements are taken at lower, mid, and upper stations of the estuary, at stations locations that may vary depending on the tide. These samples are generally collected in Spring, Summer, and Fall to capture conditions through the growing season.
