Nuclear Magnetic Resonance Data from West Fork of Dall Creek, AK 2019
Description
The West for of Dall Creek contains a burn scar (Dall City Fire 2004) surrounded by unburned black spruce forest. Nuclear magnetic resonance (NMR) data were acquired with a Dart down-borehole tool (Vista Clara, Inc., Mukilteo, Washington) form both within the burn scar from the unburned black spruce forest. Boreholes were augered to various depths throughout the study, and PVC was permanently installed in boreholes WFD1, WFD2, WFD3, and WFD4 in June of 2018. The Dart measures a thin (i.e. ~1–2 mm) cylindrical shell of soil ~ 15 cm from the center of the tool and extending vertically ~23 cm from the tool center. Dart data were logged upwards from the bottom of the borehole in 12.5- cm intervals. Resulting T2 decay time-series were analyzed using proprietary software (Vista Clara, Inc.). Data products include volumetric water content for periods of maximum freeze and thaw from 2018-2019.
