The Marsh

How are tidal marsh processes and their connections to estuarine waters regulated by sea level, storms and water and material inputs from land and sea?

Five transects in the Rowley River Estuary marsh system were established in 1998. Vegetation, sediment, and sedimentation characteristics at several sites along each transect were measured. Marsh sediment porewater nutrient concentrations are also measured at various sites in the Plum Island marshes.

Three long-term plot-level ferlization sites, a large-scale marsh fertilization, and a large-scale detritus removal experiment were initiated in 1999 and 2000. These are addressed in the Long-Term Experiments section.



USC graduate students Weihong Wang and Whitney Pate finish sprigging a 'marsh organ' with Spartina alterniflora during an April field trip. Their experiment is designed to measure the response of marsh vegetation to relative elevation.

Companion Studies:

The following datasets contain data pertaining to marsh restoration studies in the Plum Island ecosystem. These studies are not funded directly by the PIE-LTER project, but the data are presented here because of their interest to the Plum Island Sound ecosystem. Robert Buchsbaum is the Principal Investigator on these projects and is also a Principal Investigator on the PIE-LTER.

Description
A description of the vegetation transects set up at the Argilla Rd. salt marsh restoration site in Ipswich and a reference marsh (Rough Meadows) in Rowley.
Plant species percent cover in quadrats along vegetation transects at the Argilla Rd. salt marsh restoration site (Ipswich) and Rough Meadows reference marsh (Rowley – Stackyard Road area).
Plant species present along vegetation transects at the Argilla Rd. salt marsh restoration site in Ipswich and a reference marsh (Rough Meadows) in Rowley.
Measurements of the two tallest Phragmites australis stems per five meter interval along transects at the Argilla Rd. salt marsh restoration site (Ipswich) and Rough Meadows reference marsh (Rowley – 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.
