Ice-Wedge Cracking Conditions in Northern Quebec

July 1989 through August 1991 records capture temperature conditions for ice-wedge cracking in Salluit, northern Quebec. The dataset includes air temperature, soil temperature, wind speed and direction, plus temperature inside a data logger and resistance values along a cracking detection circuit. It was compiled by the Centre d'Etudes Nordiques and presented on the CAPS Version 1.0 CD-ROM in June 1998.

Use Cases

• Analyzing the relationship between air temperature, soil temperature, and the initiation of ice-wedge cracking.
• Correlating wind speed and direction data with thermal regimes in periglacial environments.
• Using resistance values from the cracking detection circuit to identify mechanical stress events in frozen ground.
• Studying seasonal and multi-year temperature trends inside a data logger deployed in a harsh Arctic climate.

Strengths

• Provides concurrent measurements of multiple environmental variables (air/soil temperature, wind) relevant to permafrost processes.
• Covers a multi-year observation period from July 1989 to August 1991 for key cracking circuit data.
• Part of a broader climatological research station network (GGD360, GGD361), providing context.

Limitations

• The record is explicitly noted as not continuous, indicating data gaps.
• Conflicting metadata exists: one platform lists a last update date of 2026-03-12, while another indicates 1992-08-31.
• Specific column names, row counts, and file sizes are unknown across all sources.
