| 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.
