PIE LTER locations of vegetation transects in Rowley salt marsh sites used for measuring long term changes.
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.

<p>This data have been collected from salt marshes in Masonboro Island and Wrightsville Beach in NC, US, in 2015 and 2016.</p> <p>The data include organic matter percent, organic carbon percent, bulk density, decomposition rate, stabilization factor, marsh elevation and vegetation cover all along transects from the channel to the inner marsh.</p>
Predicted Surficial Blue Carbon Maps for Blackbird Creek and St. Jones River Tidal Salt Marshes using 2014-2023 Landsat-8 OLI records
These data tables reflect the predictions of a gradient boosted trees model for predicting soil organic matter (SOM) in the surficial layer of tidal marsh soils. The model was trained on soil core data related to its corresponding spectral characteristics from decadal Landsat-8 Operational Land Imager data (see associated publication Warner et al. "Leveraging a decade of Landsat-8 spectral records for mapping blue carbon storage in tidal salt marshes"). This is a modeled data product designed to illustrate spatial patterns of organic matter storage as predicted by satellite data.
June - December 2009 RTK survey of salt marsh plant ground elevations to assess the accuracy of a LIDAR-derived digital elevation model.
Real time kinematic (RTK) GPS survey of ground elevations for six plant species (Spartina alterniflora, Juncus roemerianus, Batis maritima, Distichlis spicata, Salicornia virginica and Borrichia frutescens) and two non-vegetated cover classes (salt pan and intertidal mud) was carried out from June to December 2009 to assess the accuracy of a LIDAR-derived digital elevation model. In total, 1389 ground control points (GCP) were collected for the Duplin River (Sapelo Island) and Blackbeard Creek (Blackbeard Island) salt marshes.
February- March 2010 RTK survey of salt marsh plant ground elevations, plant characteristics and soil properties to support analysis of a LIDAR-derived DEM.
Real time kinematic (RTK) GPS survey of ground elevations for six plant species (Spartina alterniflora, Juncus roemerianus, Batis maritima, Distichlis spicata, Salicornia virginica and Borrichia frutescens) and two non-vegetated cover classes (salt pan and intertidal mud) was carried out from February to March 2010 to assess the accuracy of a LIDAR-derived digital elevation model. In total, 369 ground control points (GCP) were collected for the Duplin River (Sapelo Island) and Blackbeard Creek (Blackbeard Island) salt marshes with associated plant and soil charactistics (soil salinity and water content, soil organic matter, soil redox potential). Data were collected to examine the relationships between marsh soil elevation, plant habitat distribution and soil properties and to support the analysis of a a LIDAR-derived digital elevation model (DEM) and RTK data collect in 2009.
Aboveground biomass data from a Spartina alterniflora-dominated salt marsh plots in North Inlet, Georgetown, SC.
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 Spartina alterniflora-dominated salt marsh plots in North Inlet, Georgetown, SC.
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.
PIE LTER 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 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 long term study not directly part of the PIE LTER, but a companion study related to tidal restrictions and hydrological alterations of salt marshes in the Plum Island ecosystem.
