Glacier Impulse Radar Soundings from Trapridge Glacier

Field studies on Trapridge Glacier, Yukon, used a portable microprocessor-controlled instrument to record digitized echograms. Surveys up to half a kilometer long were conducted with soundings at 1 to 20 meter intervals, and subglacial temporal variations were recorded every 20 minutes over a three-day period.

Use Cases

• Model glacier bed properties by analyzing reflection of pulses from planar reflectors, using parameters for conductivity and relative dielectric permittivity of ice and bed materials.
• Extract smaller-scale parameters like the attenuation constant of glacier ice from recorded digitized echograms.
• Examine locally anomalous sections of bed topography derived from surveys conducted at 1 to 20 meter intervals.
• Study subglacial and englacial temporal variations using automatically recorded echoes from a fixed location.

Strengths

• Includes field data from surveys up to half a kilometer in length.
• Contains temporal data with echoes recorded every 20 minutes over a three-day period.
• Investigates a range of glacier bed models, including solid rock, unconsolidated debris, and frozen or wet states.

Limitations

• Data scope is focused on a single glacier (Trapridge Glacier), limiting geographic generalizability.
• The primary file format is HTML, which is not a standard structured data format for analysis.
• Sample data and specific column definitions are unavailable, complicating direct machine learning application.
