U.S. Geological Survey researchers conducted time-series ground-penetrating radar (GPR) surveys with a Sensors and Software 500-MHz Pulse Ekko Pro system. We collected common-offset data from the ground, towed behind a researcher using a snowmobile, and from the air, strapped underneath a helicopter. We also collected common-midpoint data at specific glacier locations. All the profiles are linked to coincident GPS observations. Coincident in-situ data may provide calibration information, and may be composed of any of the following: snow pits and/or snow-pit/snow-core combinations, probe profiles, and ablation stakes. This supplemental information may provide estimates of snow properties to calibrate radar velocity.
