This dataset contains transient electromagnetic (TEM) geophysical soundings acquired on drained permafrost lake basins at the North Slope of Alaska during spring fieldwork in 2019. Measurements were made using an ABEM WalkTEM with a 1600 meter squared (m^2) transmitter loop, a 200 m^2 receiver loop, and a 5 m^2 receiver loop, all in a center-nested configuration. Raw data for 15 soundings are provided in the Universal Sounding Format (USF), and results after processing (smooth constraint) with SPIA (GuidelineGeo/ABEM/Aarhus Hydrogeopyhsics) inversion software are included as tabular geolocated values. A KML indicating point location of the center of each sounding is also provided.
