(508) 289 7485 pie_im@mbl.edu http://ecosystems.mbl.edu/PIE/ Porewater is sampled monthly from May through November and bi-monthly from December though April using diffusion samplers. Samples are retrieved from triplicate poles at depths of 10, 25, 50, 75, and 100 cm. Soluble reactive phosphorus, NH4, S2, and chloride concentrations are measured in each sample according to standard laboratory protocols (SRP and NH4 – Strickland and Parson (1972); S2 – Otte and Morris (1994)). NOTES AND COMMENTS: MAR-RO-MorrisTr discontinued on 7/1/99. LTE-MP-LPP began in May 99. LTE-MP-ORT began in May 00. TYC1 and TY11 are the same sampling pole. REFERENCE CITATIONS: Otte, M. L. and J.

(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 MAR-VA-Porewater.dat Porewater nutrient concentration data [SRP, NH4+, S-2, Cl-] from several sites along the Rowley and Parker Rivers, MA and Wells NEER, ME.
