Application of distributed temperature sensing for mountain permafrost mapping

摘要: Permafrost distribution in mountains is typically more heterogeneous relative to low‐relief environments due greater variability the factors controlling ground thermal regime, such as topography, snow depth, and sediment grain size (e.g., coarse blocks). Measuring understanding geothermal high remains challenging logistical constraints. This study presents one of first applications distributed temperature sensing (DTS) periglacial measure surface temperatures a mountain permafrost area at much higher spatial resolution than possible with conventional methods using discrete sensors. DTS measures along fibre‐optic cable (i.e., ≤ 1 m). Its use can be limited by power supply calibration requirements, although recent methodological developments have relaxed some these restrictions. Spatially continuous measurements studied rock glacier provided facilitated interpretation bottom snowpack data map patchy distribution. research highlights potential for useful tool mapping, regime interpretation, conceptual model development, numerical evaluation areas permafrost.
