Geophysical sites were chosen to coincide with additional soil, hydrologic, and geochemical measurements adjacent to various low-order streams and tributaries in a mix of burned and unburned watersheds in both silty and rocky environments. Data were collected in support of the Striegl-01 NASA ABoVE project, "Vulnerability of inland waters and the aquatic carbon cycle to changing permafrost and climate across boreal northwestern North America."

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 models contained in this archive simulate infiltration and consequent runoff generation through 7 years of recovery following a wildfire in 2010. These simulations provide insight to changes in the timing of runoff generation that have implications for water quantity and quality following wildfire, with direct impacts on water supply.

The West Fork of Dall Creek is composed of unburned black spruce forest with a burn scar from the 2004 Dall City Fire. Multi-season, multi-method geophysical data were collected both within the burned and unburned areas. Geophysical techniques used include Nuculear Magnetic Resonance (NMR) and Ground Penetrating Radar (GPR) data. NMR data were collected with a down borehole Dart tool (Vista Clara Inc.). GPR data were collected with a Sensors and Software pulseEKKO pro unit and 100 mHz antennas and a high power (1000V) transmitter. Soil temperature data were collected from the unburned black...
