In Situ Measurements of Deformation and Electrical Properties Beneath a Surge-Type Glacier

First in situ measurements of deformation, electrical resistivity, and streaming potentials beneath Trapridge Glacier, a surge-type glacier in the Yukon, Canada. The dataset provides field observations of stress-strain response and electrical flow paths within subglacial sediments. Row and column counts are not specified.

Use Cases

• Analyze the relationship between shear stress, effective pressure, and deformation rate from subglacial deformation experiments.
• Model temporal changes in electrical flow paths within subglacial sediments using resistivity and streaming potential data.
• Investigate the distribution of normal and shear loading at the glacier bed using combined deformation and electrical resistivity measurements.
• Assess the use of subglacial electrode arrays to supplement pressure sensors based on observed streaming potential variations.

Strengths

• Contains the first in situ measurements of deformation, electrical resistivity, and streaming potentials beneath a surge-type glacier.
• Data provides strong evidence on the uneven distribution of loading at the glacier bed and the impact of distant pressure changes on deformation.
• Research was conducted on Trapridge Glacier, a specific surge-type glacier in the St. Elias Mountains, Yukon, Canada.

Limitations

• Dataset size, row count, column structure, and sample data are unknown, limiting immediate analytical utility.
• Data is specific to a single, small surge-type glacier, which may limit generalizability to other glacial systems.
• Available file format is HTML, which is not a standard structured data format for quantitative analysis.
