A total of 5 wells are dug to the depth of the water table under the marsh platform. Wells 1-4 are spaced approximately evenly within the first 3m of shore, with well 5 approximately 20m upland from the marsh edge. A tide gauge is placed at the river bottom directly in front of the transect. Individual pressure transducers (Motorola MPX series) are used in each well (MPX5050) and in the tide gauge (MPX5100) at the river bottom to measure water height in terms of pressure. Prior to deployment, each transducer is calibrated to determine the correlation between voltage output and water height. Once in the field, water height measurements, in terms of voltage, are recorded every 4 minutes by a HOBO H8 4-Channel External Data Logger (Onset Computers). Voltage readings are uploaded from the HOBO and are then converted to absolute water height above the river bottom.

(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 MAR-PR-Wtable-TA-2002.csv Marsh water table height, logging data from the Typha site on the upper Parker River for April-August 2002 MAR-PR-Wtable-TA-2002.csv 1 \r\n column , http://ecosystems.mbl.edu/PIE/data/MAR/data/MAR-PR-Wtable-TA-2002.csv Pipe 1 time Pipe 1 time Date and minute of water table height measurement YYYY-MM-DD hh:mm:ss NA NA = not available Pipe 1 Wy Pipe 1 Wy Height of water table above creek bottom at a given pipe location centimeter real NA NA = not available Pipe 2 time Pipe 2 time Date and minute of water table height measurement YYYY-MM-DD hh:mm:ss NA NA = not available Pipe 2 Wy Pipe 2 Wy Height of water table above creek bottom at a given pipe location centimeter real NA NA = not available Pipe 3 time Pipe 3 time Date and minute of water table height measurement YYYY-MM-DD hh:mm:ss NA NA = not available Pipe 3 Wy Pipe 3 Wy Height of water table above creek bottom at a given pipe location centimeter real NA NA = not available Pipe 4 time Pipe 4 time Date and minute of water table height measurement YYYY-MM-DD hh:mm:ss NA NA = not available Pipe 4 Wy Pipe 4 Wy Height of water table above creek bottom at a given pipe location centimeter real NA NA = not available Pipe 5 time Pipe 5 time Date and minute of water table height measurement YYYY-MM-DD hh:mm:ss NA NA = not available Pipe 5 Wy Pipe 5 Wy Height of water table above creek bottom at a given pipe location centimeter real NA NA = not available Pipe 6 time Pipe 6 time Date and minute of water table height measurement YYYY-MM-DD hh:mm:ss NA NA = not available Pipe 6 Wy Pipe 6 Wy Height of water table above creek bottom at a given pipe location centimeter real NA NA = not available 42805
