520 | |a"Knowledge of the occurrence of taliks or unfrozen ground beneath lakes in permafrost terrain is critical for understanding the interaction between surface and groundwater. Due to the contrast in electrical properties between frozen and unfrozen ground, time-domain electromagnetic (TEM) surveys may be useful for talik detection and mapping. TEM soundings were acquired over nine lakes in the vicinity of Rankin Inlet, Nunavut for talik studies. Soundings were also acquired over shallow lake terraces and onshore. One-dimensional modelling and inversion of the data show marked variability in the data and the recovered resistivity models between lakes of different sizes and different bedrock geology"--Summary. |
