UAS-Deployed programmable Tri-Frequency GPR Data Gathering Along the Alaskan Steese Highway 01/24: Providing Geospatial Resources for Extreme Cold Weather Infrastructure Analysis and Subsurface Visualization

GPR sensor data were collected on previous test sites that were tested during the summer field study exercise on Alaska's Steese Highway, as part of continued efforts to provide more geospatial data in Arctic regions relevant to cold region research. The Steese Highway is a major highway connecting the City of Fairbanks, Alaska, to the small town of Circle, Alaska, next to the Yukon River. The Steese Highway spans approximately 261 kilometers and is the only means of transportation for goods and supplies to the remote towns of both Central and Circle Alaska. The survey was conducted in January 2024 as a companion comparative dataset to the summer 2023 GPR dataset. The drone-flown GPR utilized three frequencies: 300 MHz, 150 MHz, and 100 MHz, to penetrate the ground in an effort to find the depth of permafrost in order to provide geospatial resources for extreme cold weather infrastructure analysis and subsurface visualization.
