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).

Sampling locations were recorded using a Geneq SXBlue II+ GPS Receiver. Elevation data was obtained from the PIE LTER 2005 Digital elevation model for the Plum Island Sound estuary, Massachusetts.
Data processing:
Plant data and gps locations were first entered into ArcGIS, and eventually transferred to the PIE Excel metadata and data file for uploading to the PIE web site and EDI Data Portal.
Maintenance:
Collection done for 2018.
Version 01: August 6, 2019, data and metadata updates to comply with importation to DEIMS7 and LTER Data Portal. Used MarcrosExportEML_HTML (working)pie_excel2007_Jun2019.xlsm 6/7/19 12:58 PM for QA/QC to EML 2.1.0.
