Abstract

This dataset includes heat flux and soil surface temperature data from a permafrost mound (i.e., lithalsa) located within the Tasiapik Valley, near the village of Umiujaq, Nunavik, Quebec, Canada. The data come from two different sample locations, one at the top and one at the side of the permafrost mound. At both locations, heat flux plates are buried at a depth of 8 cm, while two thermistors per location are buried at à depth of 2 and 6 cm. Data were collected from 1 November 2014 – 27 June 2021 using heat flux plates (model HFP01SC self-calibrating heat flux sensor™) and thermistors. These data support the article Fortier et al. (2023).
