Methods and protocols used in the collection of this data package
Description:

General:
This data set is part of a study including three on-going plot-level fertilization sites.  The first (LTE-MP-LPA) is in the low marsh at Law's Point along the Rowley River.  The second (LTE-MP-LPP) is in the high marsh at Law's Point along the Rowley River. The third (LTE-MP-ORT) is in a brackish water marsh on an upstream tributary of the Parker River.  Biomass sampling is slightly different at each site, and is accomplished non-destructively at the LTE-MP-LPA and LTE-MP-ORT sites, and destructively at the LTE-MP-LPP site.  Biomass sampling at LTE-ME-ORTwas discontinued after August 2008.
At each site a system of boardwalks was built to incorporate 12 experimental plots (1m2 each).  There are 4 treatments (three replicates each) within the boardwalk structure.  The 4 treatments are Control, N-fertilized, P-fertilized, N+P fertilized.  Additionally, at each site there are 3 control plots and 3 N+P fertilization plots external to the boardwalk structure.  These external plots contain porewater samplers, and, in some cases, biomass census plots. 
Fertilizer is buried at several locations within each treated plot, monthly, from May-Sept.  From 1999-2001 the annual fertilization rate was 30 molN/m2/y and/or 15 mol P/m2/y.  From 2002 to present fertilization rate is 7.5 mol N/m2/y and/or 3.75 mol P/m2/y.  N fertilizer was NH4NO3 through 2008, and currently is nitrate/urea/sulfate (34-0-0).  P fertilizer is P2O5 (0-44-0).
Sampling Description:
The plant census method at LPA is non-destructive.  Two permanent subplots were established in each plot within the boardwalk.  Each subplot is 10cmx10cm.  The subplots are labeled 1&2, with subplot 1 being the more northerly and/or westerly subplot.  In May and June, plants in the subplots are tagged with bird ID bands.  Approximately monthly from May to October, heights of the tagged plants and associated culms are measured to the nearest cm.  Plant heights are read into a digital recorder.  Descriptions of the locations of the plants within the quadrat are also recorded (e.g. northwest corner or northwest of tag #xxxx).  Plant measurements are always taken with the observer on the same side of the quadrat for ease in tracking  individual plants throughout the growing season.
The plant census at LPA began in June 1999.  All 24 subplots were censused until October 2003.  Beginning in May 2004, only the 6 Control subplots were censused.  In May 2006 the Control census plots (and porewater samplers) were relocated outside of the boardwalk structure because of potential contaminatin from fertilized plots.  The census subplots kept the same id#’s from when they were within the boardwalk for continuity within the ACCESS database.
Data processing:
Plant data are entered first into an EXCEL spreadsheet, and eventually transferred to an ACCESS data base.  Outputs from ACCESS are processed with two FORTRAN programs.  The FORTRAN programs use algorithms to convert the ACCESS data outputs to plant weight, density, births, deaths and growth (Morris and Haskin, 1990).  Fortran outputs are entered into SAS programs to calculate treatment means of biomass, density, and productivity.

Abstract: 

The Plum Island Ecosystems (PIE) LTER is developing a predictive understanding of the response of a linked watershed-marsh-estuarine system in northeastern Massachusetts to rapid environmental change. Over the last 30 years, surface sea water temperatures in the adjacent Gulf of Maine have risen at 3 times the global average, rates of sea-level rise have accelerated, and precipitation has increased. Coupled with these changes in climate and sea level are substantial changes within the rapidly urbanizing watersheds that influence water, sediment, and nutrient delivery to the marsh and estuary. In PIE IV our focus is on: Dynamics of coastal ecosystems in a region of rapid climate change, sea-level rise, and human impacts.
