Continuous profiles of electromagnetic wave velocity and water content in glaciers : an example from Bench Glacier , Alaska , USA

  title={Continuous profiles of electromagnetic wave velocity and water content in glaciers : an example from Bench Glacier , Alaska , USA},
  author={John Hamilton Bradford and Joshua Ben David Nichols and Thomas Dylan Mikesell and Joel T. Harper},
We conducted two-dimensional continuous multi-offset georadar surveys on Bench Glacier, south-central Alaska, USA, to measure the distribution of englacial water. We acquired data with a multichannel 25MHz radar system using transmitter–receiver offsets ranging from 5 to 150m. We towed the radar system at 5–10 kmh with a snow machine with transmitter/receiver positions established by geodetic-grade kinematic differentially corrected GPS (nominal 0.5m trace spacing). For radar velocity analyses… CONTINUE READING
