Grab samples were taken at 11 sites along a 24 km transect from the dam to the mouth of the estuary. These samples have generally been collected in Spring and Fall and are done in conjunction with metabolism transects measuring dissolved oxygen levels. The Spring and Fall transects correspond to the high-flow, pre-growth season in April and the low-flow, post-growth season in September.

(508) 289 7485 pie_im@mbl.edu http://ecosystems.mbl.edu/PIE/ EXPERIMENTAL DESIGN AND METHODS: For all dates during 1994, samplings were made within 2 hours of high tide, except for samples that have a station designation of "low", which were collected within 2 hours of low tide. For all other dates, samples were collected Salinity was measured using a refractometer or calculated from conductivity. Conductivity was measured using a Hydrolab H2O probe with a Scout 2 Water Quality Data System. Temperature was measured using the Hydrolab H2O probe or a field thermometer. Conductivity and temperature have also been measured using a YSI Sonde probe since 2004. A secchi disk was used to obtain the secchi depth, which was considered to be the shallowest depth at which black and white sections of the disk were indistinguishable. During 1994, approximately 10 liters of water were collected in an HDPE carboy. 1 liter polycarbonate bottles were used for later water collections. In the lab, the water was filtered through a GFF filter within 3 hours of collection, and preserved immediately for later analysis of dissolved materials, and filters preserved for later analysis of particulate materials. For details on analytical procedures, see Analytical Methods. NOTES AND COMMENTS: Samples for NH4 analysis were filtered and preserved in the field, immediately upon collection, for all transects from 3/94 to 8/94. For the July 11, 2000 transect, water samples for nutrient analysis were collected at specific salinities, rather than at the designated stations. For the September 11, 2001 transect, water samples for nutrient analysis were collected at specific salinities corresponding to the water masses in which the metabolism measurements were made during the dusk transect on September 10, 2001. Sampling at specific salinities has been done consistently since the April 2006 transect. Contact Chuck Hopkinson (chopkins@uga.edu) for more details on sampling. Starting in 2008, we recorded the actual location at which the nutrients were sampled (because they are sampled in salinity space, this location will vary depending on the salinity gradient and depending on the tide at which the samples were taken for each transect. Sites are measured using GPS and state coordinates no longer included in database. 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 EST-PR-NUT.csv Water-column nutrient and particulate transects along the Parker River Estuary.
