(508) 289 7485 pie_im@mbl.edu http://ecosystems.mbl.edu/PIE/ General: There are three on-going plot-level fertilization sites. The first (LTE-MP-LPA) is in the low marsh at Law's Point along the Rowley River. The second (LTE-MP-LPP) is in the high marsh at Law's Point along the Rowley River. The third (LTE-MP-ORT) is in a brackish water marsh on an upstream tributary of the Parker River. SET sampling at the Parker River site was discontinued after May 2008. At each site a system of boardwalks was built to incorporate 12 experimental plots (1m2 each). There are 4 treatments (three reps each) within the boardwalk structure. The 4 treatments are Control, N-fertilized, P-fertilized, N+P fertilized. Additionally, at each site there are 3 control plots and 3 N+P fertilization plots external to the boardwalk structure. These external plots contain porewater samplers, and, in some cases, biomass census plots. In May 2006 the control porewater plots and control census plots at all three sites were moved because of potential contamination from fertilized plots. Fertilizer is buried at several locations within each plot, monthly, from May-Sept. From 1999-2001 the annual fertilization rate was 30 molN/m2/y and 15 mol P/m2/y. From 2002 to present fertilization rate is 7.5 mol N/m2/y and/or 3.75 mol P/m2/y. N fertilizer was NH4NO3 through 2008, and currently is nitrate/urea/sulfate (34-0-0). P fertilizer is P2O5 (0-44-0). Sampling Description: Triplicate SET benchmarks are permanently installed between fertilized and control plots at each of the three research sites. Each SET benchmark is positioned such that 27 elevation readings can be taken in a fertilized plot (9 readings in 3 subplots) and 27 elevation readings can be taken in a control plot. At each subplot, the SET sampling arm is leveled, 9 brass pins are lowered to the marsh surface, and the height of each pin above the sampling plate is measured and recorded. Surface elevations are measured monthly from May through October at LTE-MP-LPA and LTE-MP-LPP, and in May and October only at LTE-MP-ORT. Triplicate original-style SET benchmark posts were permanently installed at each site. Each SET consists of a permanently installed post and a removable arm. The arm has a vertical and a horizontal component. The vertical component fits into the SET benchmark post; the horizontal component reaches out over the experimental subplot and has a square plate at the end through which 9 pins are lowered. Each SET post is associated with two adjacent plots (one control, one NP fertilized). Each SET benchmark post is positioned such that 27 elevation readings can be taken in a fertilized plot (9 readings in 3 subplots) and 27 elevation readings can be taken in a control plot. Plots are numbered. Subplots are identified as L, C, or R for left, center and right, when facing the plot (back to the SET post). To measure elevations, the SET arm is locked in place over each subplot, is leveled, and the 9 brass pins are lowered to touch the sediment surface and held in place with a clip. Pin heights are measured from the top of the nut on the plate to the top of the pin, and read into a digital recorder. The recordings are transcribed into one master SET pin height data set. SET readings occur approximately monthly, from May-October. The ORT SET was discontinued in 2008. The horizontal portion of the removable part of the PIE LTER SET can be correctly installed and leveled in several positions: the arm can be extended all the way forward, all the way back, and anywhere in between. All SET measurements are made with the arm all the way back, i.e. with the plate being as close to the SET post as possible and the SET arm being as short as possible. The SET was manufactured by Nolan’s Machine Shop in Lafayette LA; 337-235-5261. Replacement pins or collars can be purchased from Nolan’s. Stainless steel parts (roll pins etc) come from McMaster-Carr. Measuring pins are held in place with badge clips, available at office supply stores. NOTE about Research Location (lat/long/elevation): SET plates at each LPA and LPP SET posts were surveyed for latitude, longitude and elevation in 2006, 2008, 2009, and 2010 by MBL staff. The 2009 survey results are presented above. Surveys were not conducted at ORT. The lat/long for ORT in the above table were estimated from maps. The elevation of the plate is determined when the arm is level and the plate is in the center subplot, pointing towards West Creek. Surveys were not conducted at ORT. The lat/long for ORT in the above table were estimated from maps. Latitude and Longitude are reported as decimal degrees in the NAD 83 Datum. Elevation is reported as NAVD 88, orthometric height (meters), and is measured at the surface of the SET table from which pins are dropped. This elevation, taken from FastStatic measurements using a Trimble 4800 receiver and TSC-1 controller (from UNAVCO www.unavco.org), can be used directly with the SET geometry and the pin height measurements found in the dataset to calculate the elevation of the marsh. Total pin length for the original SETs is 91.44cm and the height of the nut on the plate is 1.0 cm. Therefore the marsh surface is at: (plate elevation (in m) - (0.9144 - (pin height (in m) + 0.01)). For example for LPA plot 2 subplot C in June 1999 pin 1 the pin ht is 15.3cm and the plate elevation is 1.826m. The marsh elevation is (1.826-(0.9144-(0.153+.01))) or 1.0746m above NAVD88.

(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 LTE-MP-SET-raw.csv Marsh surface elevation data from three marsh fertilization experimental research sites.
