Aliyeva, Mehriban; Yasmin, Allin Alya; Banaskiewicz, Benjamin; Miesner, Frederieke; Boike, Julia: Snow depth measurements (MagnaProbe) in the Mackenzie River Delta, Northwest Territories (Canada), March 2025 [dataset]. PANGAEA, https://doi.pangaea.de/10.1594/PANGAEA.997103 (dataset in review)
Abstract:
The dataset contains over 1200 snow depth measurements collected at four legacy waste sites (drilling mud sumps): Tuktuk A-12, Tuk L-09, Kamik F-38, and Parsons E-02, located along the Inuvik-Tuktoyaktuk Highway in the Mackenzie River Delta area, Northwest Territories, Canada as part of a larger field effort to investigate the thermal state of permafrost within drilling mud sumps using geophysical and environmental monitoring techniques. All measurements were collected in March 2025. Snow depth was measured with an in-house built Magnetic Snow Depth Probe (MagnaProbe). The MagnaProbe can be used to measure snow depth along transects or in grids while the observer walks or skis on the snow surface. The measurement rod is pushed through the snowpack until it reaches the ground surface, while a plastic disk on the rod stays at the snow surface. The snow depth is determined from the position of the plastic disk along the metal rod. At the same time, the GPS position is recorded, resulting in a dataset containing both snow depth and position.
