Year 2018, 15 minute measurements of water column temperature, salinity, oxygen and depth in Plum Island Sound at the Ipswich Bay Yacht Club, Ipswich, MA.
The file contains measurements of the two tallest Phragmites australis stems per five meter interval along transects at the Argilla Rd. salt marsh restoration site (Ipswich, MA) and Rough Meadows reference marsh (Rowley, MA – Stackyard Road area). The culvert feeding Argilla Marsh was enlarged in late November 1998, thus data from 1999 onward is considered as representing a hydrologically restored marsh.
A description of transects used for long term studies of marsh vegetation in Rowley, MA. Four sites ((12 transects) were originally set up to study the impact of salt marsh haying. Two of these sites (labeled McH and EPH) were regularly hayed until 2002. The other two (PUH and CC) were reference sites. Two additional sites labeled RM (8 transects) were originally set up to track invasion by Phragmites australis.

Measurements of water column depth at 15 minute intervals in Plum Island Sound at the Ipswich Bay Yacht Club, for year 2018. OTT radar level sensor (RLS) installed September 20, 2011 out of the water under the concrete pad on the Ipswich Bay Yacht Club pier, Ipswich, MA. RLS was mounted so that continuous year round measurements can be conducted without the concern of ice flows damaging the sensor.

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.
We sampled the coffee-bean snail, Melampus bidentatus in four habitats (Spartina patens, tall/creekside S. alterniflora, stunted S. alterniflora, and transitional S. patens) in 8 marshes in the northeast U.S. , including the Plum Island Estuary. Overall, snails were larger in the stunted S. alternilfora and transitional S. patens habitats than in S. patens ones. Only 2 snails were found in the tall S. alterniflora.
Organisms, plants and animals, were collected along a transect in Greenwood Creek, Ipswich, MA from the Ipswich sewage treatment plant outfall pipe to the mouth of Greenwood Creek on the Ipswich River. Tissue from the organisms was analysed for del 13C and del 15N to determine if the treatment plant effluent del 15N signal could be detected in the biota of Greenwood Creek.

Year 2016, continuous measurements, every 15 minutes were made of conductivity, water temperature in a small headwater stream, Saw Mill Brook, Burlington, MA, draining a highly suburban catchment (72% residential) in the Ipswich River watershed. Due to sedimentation within the datalogger housing, there are periods when the datalogger lost hydrological connection with the stream (i.e., during low flow). As such, data has been flagged to remove these erroneous readings.
