(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-TC-NUT.dat Tidal creek nutrient sampling, 1998 - 2001 LTE-TC-NUT.dat 1 column , http://ecosystems.mbl.edu/PIE/data/LTE/data/LTE-TC-NUT.dat Creek Creek creek sampled creek sampled STATE X STATE X x coordinates (meters) in MA state plane NAD 83 meter real STATE Y STATE Y y coordinates (meters) in MA state plane NAD 83 meter real LAT LAT Latitude in NAD 83 geographic coordinates (decimal degrees) degree real LON LON Longitude in NAD 83 geographic coordinates (decimal degrees) degree real Date Date date (dd-mmm-yyyy) dd-mmm-yyyy Time Time time 24 hr (hh:mm) hh:mm Tide Tide stage and direction of tide when sample was collected stage and direction of tide when sample was collected Branch Branch branch of creek sampled branch of creek sampled Temp Temp temperature of the water degree real Sal Sal salinity (ppt) partsPerThousand real NO3 NO3 nitrate + nitrite (µM-N) microMolesPerLiter real NH4 NH4 ammonium (µM-N) microMolesPerLiter real PO4 PO4 soluble reactive phosphorus (µM-P) microMolesPerLiter real TDN TDN total dissolved nitrogen (µM-N) microMolesPerLiter real DON DON dissolved organic nitrogen (µM-N) microMolesPerLiter real TDP TDP total dissolved phosphorus (µM-P) microMolesPerLiter real DOP DOP dissolved organic phosphorus (µM-P) microMolesPerLiter real DOC DOC dissolved organic carbon (uM-C) microMolesPerLiter real Chla Chla chlorophyll a (ug/L) microgramsPerLiter real Part C Part C particulate carbon (uM-C) microMolesPerLiter real Part N Part N particulate nitrogen (uM-N) microMolesPerLiter real Comments Comments comments about data comments about data ratio of two quantities as parts per thousand (1:1000) µM = µmoles per liter of solution micrograms per liter per day
