Tissue from the organisms was analysed for del 13C and del 15N to determine if the treatment plant effluent del 15N signal could be detected in the biota of Greenwood Creek.

Tissues of animals and plants were dissected, dried, checked for carbonate contamination and analyzed at the Marine Biological Lb, Ecosystems Center Stable Isotope Lab. Anne Giblin

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-TC-GreenwoodIsotopes.dat Stables isotopes of organisms along a transect from the Greenwood Creek outfall pipe to the Ipswich River LTE-TC-GreenwoodIsotopes.dat 1 column , http://ecosystems.mbl.edu/PIE/data/LTE/data/LTE-TC-GreenwoodIsotopes.dat Sample # Sample # Sample number Sample number Sampling Date Sampling Date Date of sampling dd-mmm-yyyy Analysis Date Analysis Date Date of analysis dd-mmm-yyyy Distance Distance Distance away from outfall pipe kilometer real Location Location Sample location number Sample location number Sample ID Sample ID Organism sampled Organism sampled 13C 13C delta 13C, isotope ratio 13C/12C partsPerThousand real 15N 15N delta 15N, isotope ratio 15N/14N partsPerThousand real ratio of two quantities as parts per thousand (1:1000)
