Sea ice thickness profiles were measured with surface-based electromagnetic induction, a standard geophysical method. This method returns the depth to the electrical conductivity horizon between the lower-conductivity sea ice and higher-conductivity sea water. We used a Geonics EM31 device in the so-called horizontal dipole configuration. Transects were made by towing the EM31 in a sled or kayak with periodic measurements of snow thickness and GPS location. Most transects also include Differential Global Positioning System (DGPS)-derived surface elevation measurements. Ice thickness was derived from the EM31 measurements using a calibration from apparent conductivity to ice thickness determined locally in Barrow (Mahoney et al. 2007). See the metadata files below for more information. Data Citation: Druckenmiller, M., H. Eicken, M. Kaufman, A. Mahoney. (Sept 25, 2008, Updated 2012).
