This datalayer is a gridded data set of cell length, corresponding with an estimate of river length, for rivers in Plum Island Sound watershed. The resolution is 120 m x 120 m. This layer gives length of each grid cell (either as 120m if vertical or horizontal, or 169.7 if diagonal). This information is derived from the flow direction data file: WAT-RGIS-120m-FlowDirection.asc Provide length of river, uncorrected for sub grid cell meandering, which is assumed to be relativelty small.
This datalayer is a gridded data set that identifies for each pixel the stream order that drainage from the pixel initially enters into the river network. The resolution is 120 m x 120 m. Based on the flow direction in: WAT-RGIS-120m-FlowDirection.asc. First order streams at the 120m resolution are equivalent to third order when calculated at the pixel level from the drainage direction grid (i.e. 3rd order pixels are equivalent to 1st order streams, 4th order pixels are second order streams, etc). Idenitify the distribution of inputs from land to streams of different sizes.
This datalayer is a gridded data set of the estimated distance (km) to ocean from each point in the gridded river network. The resolution is 120 m x 120 m. Based on the flow direction in: WAT-RGIS-120m-FlowDirection.asc Provide the distance to ocean for each grid cell.
This datalayer is a gridded data set of the contributing area to each grid cell for rivers in Plum Island Sound watershed. The resolution is 120 m x 120 m. This layer gives drainage area (km2) of each grid cell based on the flow directions in: WAT-RGIS-120m-FlowDirection.asc Provide the drainage area for each grid cell.
Year 2009, continuous measurements, every 10 minutes, were made of stage, water temperature in Cart Creek, Newbury, MA, a small headwater stream draining a mainly forested catchment (55% forest + 19% wetland) in the Parker River watershed.

A description of the transects that were set up to study the impacts on the salt marsh vegetation of nutrient enrichment from the Ipswich Wastewater Treatment Facility on Greenwood Creek in Ipswich, MA, USA. The marsh around Clubhead Creek, Rolwey, MA, USA was used as a reference.
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 2018.

We deployed an eddy covariance system to measure ecosystem-atmosphere exchange of CO2 above a low marsh system (Spartina alterniflora) located within the Shad creek catchment off Plum Island Sound, Rowley MA. The data represents CO2 exchange for early April through early November 2018. This site was established in 2015.
