► Methods
- Past Methods (no longer in use)
- Recharge sampling
- Started: 1995-06-01
Ended: 1996-12-31 - Method Description: Precipitation samples collected weekly from 16 stations in the area are used to monitor isotopic composition of recharge to groundwater. Water samples are measured for delta 18 O composition.
- Started: 1995-06-01
- Oxygen isotopic composition sampling
- Started: 1995-06-01
Ended: 1996-12-31 - Method Description: Eight wells are sampled and analyzed for delta 18 O composition. Continued isotopic analysis of groundwater samples provides a means for detecting the altitudinal and seasonal isotope signatures in the bedrock groundwater system to compare with precipitation signitures. This information is used to identify upper elevation areas of recharge and determine travel rates from the recharge zones to lower elevations.
- Started: 1995-06-01
- Oxygen isotopic analysis
- Started: 1995-06-01
Ended: 1996-12-31 - Method Description: Over 1000 samples were collected for oxygen isotopic composition and analyzed at the University of Vermont's Stable Isotope lab.
- Instrumentation: VG SIRA Series II Isotope Ratio Mass Spectrometer
- Quality Control Measures: Normalized to values obtained for standards
- Started: 1995-06-01
► Sampling Equipment
- No sampling equipment recorded for this dataset
► Site Characteristics
- Site Description: Uppermost basin of the Browns River including the slopes of Mt Mansfield. Stations at summit, Stevensville Brook and Browns River headwaters. Five sampling points on State Forest and UVM Natural Area, 3 additional sites in the VMC area on private lands. Additional sites throughout the basin.
