WAT-VA-StreamNutrient Data for nutrient time course samplings during rain events and base flow samplings in 1992 and 1993 for 8 streams in the Plum Island Sound watershed.
WAT-IP-catchments Nutrient data set of Ipswich River tributaries located in first- and second- through fourth-order catchments. Data are for base-flow conditions in all but the April 2000 set which was a storm event.
WAT-MBL-IP-catchments Nutrient data set of Ipswich River tributaries located in first- and second- through fourth-order catchments. Data are for base-flow conditions in all but the April 2000 set which was a storm event. This file duplicates data in the file WAT-IP-catchments in order to standardize station ID among different sample periods.
WAT-UNH-IP-catchments Nutrient data set of Ipswich River headwaters with help from Ipswich River Watershed Association.
WAT-UNH-PR-catchments Nutrient data set of Parker River headwaters with help from Parker River Cleanwater Watershed Association.
WAT-IP-1998Monthly Nutrient data set for the Ipswich River main stem, major tributaries, and headwaters. Data are from base flow conditions. Samplings were from July 1998 to July 1999, and were collected and analyzed by MBL.
WAT-IP-MonthlySampling Nutrient data set for the Ipswich River main stem, major tributaries, and headwaters. Data are from base flow conditions except where indicated as storm flow. Samplings were from March 1999 to May 2001, collected by the Ipswich River Watershed Association (IRWA) and analyzed at MBL.
WAT-VA-rainfall Solute data of wet deposition for the Ipswich River basin. Samples were collected on an event basis when possible, and otherwise collected on a weekly basis. Samplings are from May 2000 to June 2001, and were collected and analyzed by MBL.
