(508) 289 7485 pie_im@mbl.edu http://ecosystems.mbl.edu/PIE/ Benthic sediments were collected at low tide using 60 cc syringe corers with 2.65 cm diameters. Surface to 2 cm depths were sectioned and placed in 60 cc polypropylene centrifuge tubes and frozen for later chlorophyll extraction (see ANALYTICAL METHODS).Total volume of sediment is 11.03 cc. CALCULATIONS: % loss on ignition = (dry wt – ash wt)/dry wt Porosity = (wet wt – dry wt)/wet wt Bulk density = dry wt(g)/sediment volume (cc) Mg/m2 = mg/m3 x depth (.02m) Anne Giblin

(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-BenChl.dat Tidal creek benthic chlorophyll LTE-TC-BenChl.dat 1 column , http://ecosystems.mbl.edu/PIE/data/LTE/data/LTE-TC-BenChl.dat Date Date Date of sampling dd-mmm-yyyy Creek Creek Name of creek Name of creek Branch Branch Name of creek branch Name of creek branch New Branch New Branch Name of new creek branch Name of new creek branch Distance Distance Distance in creek meter real New Distance New Distance New distance in creek meter real Habitat Habitat Sediment habitat type, marsh or plant type Sediment habitat type, marsh or plant type Chla areal Chla areal Areal concentration of benthic chlorophyll a milligramsPerSquareMeter real Phaeo areal Phaeo areal Areal concentration of phaeophytin milligramsPerSquareMeter real Chla conc Chla conc Volumetric concentration of benthic chlorophyll a milligramsPerCubicMeter real Phaeo conc Phaeo conc Volumetric concentration of benthic phaeophytin milligramsPerCubicMeter real %loss %loss % loss on ignition of sediment weight percent real Porosity Porosity Porosity of sediments (fraction) dimensionless real Bulk Density Bulk Density Bulk density of sediment gramsPerCubicCentimeter real Comments Comments Comments about specific data Comments about specific data Comments Comments Comments about specific data Comments about specific data Comments Comments Comments about specific data Comments about specific data ratio of two quantities as percent composition (1:100)
