Thirty-six of these cores were processed for aboveground and belowground biomass (roots, rhizomes, detritus) . Results for belowground biomass presented here. Above ground biomass results are presented in file STP-LENS-2009-above-biomass. The remainder 36 of these cores were processed for bulk density and bulk organic content (from loss on Iinition, LOI) and results are presented in file STP-LENS-2009-geotechnical.

(508) 289 7485 pie_im@mbl.edu http://ecosystems.mbl.edu/PIE/ Coring was done with a hand held half-cylinder auger (8cm diameter) to insure cores with little vertical compression, thus the root and soil profiles would be intact. Cores were taken from 6 small primary creeks within four major creek areas: Two primary creeks within Sweeney Creek, right and left branch (5 years fertilized - since 2004) Two primary creeks within West Creek, right and left branch (used as reference since 2004) One primary creek within Clubhead Creek, right branch (one year fertilized - 2009) One primary creek within Nelson Creek, left branch (reference) In each primary creek, 6 sites in creek bank tall-form S. alterniflora were chosen along the length of the creek, 3 on each bank. Each site was co-located with a cross-sectional transect so that the elevation of the S. alterniflora can be determined (site # refers to white PVC transect pole #) .Latitude and longitude were noted. At each site, we took 2 cores using the auger: 1 for root and shoot biomass centered on a single plant and 1 for geotechnical properties taken in an adjacent area. For the biomass core, the aboveground stem(s) centered above the core was cut and stored, and the belowground core material was sectioned at the following intervals:0-5 cm, 5-10cm, 10-20cm, 20-30cm, and 30-50cm. These samples were brought back to the lab for washing and measuring of longest stem length, aboveground dry weight, and belowground dry weight of separated roots, rhizomes, and detrital material.

(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-TIDE-LENS-2009-below-bio.csv 2009 LENS belowground biomass core results LTE-TIDE-LENS-2009-below-bio.csv 1 \r\n column , http://ecosystems.mbl.edu/PIE/data/LTE/data/LTE-TIDE-LENS-2009-below-bio.csv Location Location creek name and branch code SW-R Sweeney right SW-L Sweeney left WE-R West right WE-L West left CL-R Clubhead right NE-L Nelson left Site Number Site Number coring location based on pole number for each creek coring location based on pole number for each creek Collection Date Collection Date date of sample collection dd-mmm-yyyy Latitude Latitude latitude latitude Longitude Longitude longitude longitude Biomass Core Segment Biomass Core Segment biomass core depth (cm) centimeter real Live Rhizomes Live Rhizomes dry weight of live rhizomes (g) gram real Live Roots Live Roots dry weight of live roots (g) gram real Detritus Detritus dry weight of detrital material (dead roots and rhizomes included) (g) gram real
