The West Fork of Dall Creek is located ~100km southwest of Coldfoot, AK along the Dalton Highway, south of the Brooks Range. Five ground penetrating radar (GPR) profiles were collected on 4/4/2019 at the West Fork of Dall Creek in interior Alaska. The West Fork of Dall Creek is composed of unburned black spruce forest with a burn scar from the 2004 Dall City Fire. All collected profiles, other than the Central Midpoint Survey (CMP), transect the burn scar between start and end locations in unburned black spruce forest. Data were collected with a Sensors and Software pulseEKKO pro unit and 100 mHz antennas. Four of the lines were conducted as common offset surveys with manual data collection that employed a consistent...
The West Fork of Dall Creek is located ~100km southwest of Coldfoot, AK along the Dalton Highway, south of the Brooks Range. The West Fork of Dall Creek is composed of unburned black spruce forest with a burn scar from the 2004 Dall City Fire. HOBO Tidbit v2 temperature data loggers that recorded soil temperature were installed in the unburned black spruce forest adjacent to the burn scar on 5/10/2017 and removed on 6/26/2018. Data were collected from depths of 10, 30, 50, and 70 cm.
The West Fork of Dall Creek is located ~100km southwest of Coldfoot, AK along the Dalton Highway, south of the Brooks Range. The West Fork of Dall Creek is composed of unburned black spruce forest with a burn scar from the 2004 Dall City Fire. Nuclear magnetic resonance (NMR) data were acquired with a Dart down-borehole tool (Vista Clara, Inc., Mukiltea, Washington) within both the burn scar and 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...
