For data that corresponds to a "INT TOP" and "INT BOT" entry, sediment cores for porewater extraction were sectioned by depth (in a glove bag under N2 for any samples that have HS-1 or PO4 -3 data). Porewater was removed from muddy sediments by centrifuging sections of mud for 15 minutes. At sandy sites it was necessary to use a "split" centrifuge tube with filter support. Centrifugation for 15 minutes forces porewater though the filter into the bottom of the tube. Nutrients, sulfides, pH and alkalinity in porewaters were analyzed (see ANALYTICAL METHODS). For data that does not correspond to a "INT TOP" and "INT BOT" entry, porewater samples were obtained through the use of a whole-core squeezer. Teflon filter rods were inserted into holes drilled at intervals along the core tubing. Pressure was slowly applied (vertically), and water was extracted into syringes. Sediment redox potential (Eh) was measured in separate cores using an Eh probe. Portions of sediment were dried and analyzed on a Perkin Elmer Elemental Analyzer for carbon and nitrogen content, after acidifying samples to remove carbonates. Portions of wet sediment were analyzed for chlorophyll a and phaeopigment concentrations after extraction with acetone and sonication (see ANALYTICAL METHODS).

(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 BEN-PR-Sediment.csv Sediment porewater nutrient, sulfide, pH, and alkalinity, sediment redox, and bulk sediment carbon, nitrogen, chlorophyll a and phaeopigments.
