(508) 289 7485 pie_im@mbl.edu http://ecosystems.mbl.edu/PIE/ 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 theLTE-MP-LPP site. Biomass sampling at LTE-MP-ORT was discontinued after August 2008. Sampling Description: Each experimental site has triplicate 1-m2 plots that are fertilized with N (7.5 mol N/m2/y), P (3.75 mol P/m2/y ), both N and P, or neither N nor P (controls). Fertlization occurs during the growing season only. At LTE-MP-ORT, there are two randomly placed 32cmx32cm subplots are placed per plot for sampling each month. The diameter of the culm at the base of the plant and the number of leaves on each Typha plant within each sub-plot is recorded each month. Starting in 2004, only the C and P plots were censused. Data processing: Plant measurements are entered into an EXCEL database, then transformed to biomass using allometric equations (after Daoust, R.J. and D.L. Childers. 1998. Aquatic Botany 62:115-133.). Anne Giblin

(508) 289 7485 pie_im@mbl.edu Information Manager The Plum Island Ecosystems (PIE) LTER is an integrated research, education and outreach program whose goal is to develop a predictive understanding of the long-term response of watershed and estuarine ecosystems at the land-sea interface to changes in climate, land use and sea level. The principal study site is the Plum Island Sound estuary, its coupled Parker, Rowley and Ipswich River watersheds and the adjacent coastal ocean, the Gulf of Maine. The PIE LTER focuses on how several aspects of global change influence organic matter and inorganic nutrient biogeochemistry and estuarine foodwebs. The inputs of organic matter and nutrients from land, ocean and marshes interact with the external drivers (climate, land use, river discharge, sea level) to dictate the extent and degree of nutrient and organic matter processing and determine the spatial patterns of estuarine productivity and trophic structure. This material is based upon work supported by the National Science Foundation under Grants OCE-9726921, OCE-0423565. Any opinions, findings, conclusions, or recommendations expressed in the material are those of the author(s) and do not necessarily reflect the views of the National Science Foundation. The Plum Island Ecosystems (PIE) LTER site, is located in northeastern Massachusetts, 42.72 N, 70.85 W. The PIE LTER lies at the interface of a thinly soiled, formerly glaciated New England land mass and the highly productive Gulf of Maine. Three watersheds comprise the estuarine drainage basin: Parker (155 km2), Rowley (26 km2) and Ipswich (404 km2). The Ipswich River watershed is highly urbanized with Boston "bedroom" communities encroaching in the headwater region while the Parker is less urbanized and retains a higher proportion of forest. -71.2198 -70.7568 42.8276 42.4965 0 100 meter uid=PIE,o=lter,dc=ecoinformatics,dc=org all public read LTE-MP-ORT-biomass.dat Aboveground biomass of Typha sp. at Upper Parker River brackish marsh site.
