(508) 289 7485 pie_im@mbl.edu http://ecosystems.mbl.edu/PIE/ Marker Horizons are a thin layer of Feldspar. Marker Horizons depths are measured each spring and fall. Each SET site has one Marker Horizon; three replicate cores are taken from each horizon during samplings. The depth of sediment accreted above the feldspar marker is measured on 4 side of the rectangular core using calipers. Measurements are made to the top of the feldspar layer. Cores are replaced after the measurements have been made. The values recorded in the data file represent sediment above marker horizon at the time of measurement. It is important to note that different cores are taken during each measurement, thus core A on date “X” can not be to compared to core A on date “Y”. For comparisons over time, measurements should be averaged over all “cores” and “replicates” for each individual SET. Cores or “Plugs” are taken from each horizon using a kitchen knife. This method is not ideal for several of our more wet sites. There is a high probability of erroneous measurement in sites that are very wet. We are working on a better method for sampling. For more information on SET and Marker Horizons see: http://www.pwrc.usgs.gov/set RESEARCH LOCATION: Latitude and Longitude reported as decimal degrees in the NAD 83 Datum. Elevation is reported as NAVD 88, orthometric height (meters), and is currently an unprocessed measurement of the SET insert pipe. For more information please contact Aaron Strong (astrong@mbl.edu). Locations for Levine’s SET 2-3 are not available at this time.

(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-RO-Marker-Horizon.csv Marsh surface marker horizon measurements at each Surface Elevation Table (SET) site.
