Ground-Based Radar Sounding of Englacial Water on Storglaciaren, 2001-2002

Storglaciaren in Arctic Sweden was surveyed in July 2001 and 2002 using ground-based ice-penetrating radar at 50 and 100 MHz frequencies. The data consist of closely spaced grids from four locations, acquired to study how water moves from the glacier surface to its bed through cavities and conduits. The radar portion of this project was carried out by St. Olaf College.

Use Cases

• Mapping englacial water conduits and cavities based on radar reflections.
• Studying the evolution of subglacial hydrological systems over time as described in the project purpose.
• Analyzing polythermal glacier structure using dual-frequency (50 and 100 MHz) radar data.
• Correlating radar-imaged features with borehole observations from co-investigators.

Strengths

• Data acquired over two field seasons (July 2001 and 2002).
• Surveys conducted at two distinct radar frequencies (50 and 100 MHz).
• Closely spaced grids were made in four specific locations on the glacier.

Limitations

• Individual radar traces are not geolocated, as stated in the description.
• Column-level documentation is absent; field semantics must be inferred after download.
