This release contains geophysical data from the Kuparuk aufeis associated with the manuscript "Seasonal thaw dynamics of an aufeis feature inferred from surface geophysical methods." Data were collected in two campaigns in September 2016 and April 2017 with the purpose of investigating freeze-thaw dynamics below the aufeis feature during maximally frozen and maximally thawed conditions. Ground penetrating radar common offset data from both campaigns (160MHz and 80MHz) is presented, including interpreted depths to interfaces (permafrost, ice-frozen ground interface, and talik surface). Surface nuclear magnetic resonance data and inverse results are also included from April 2017 as well as interpreted talik thicknesses. Temperature data from 46 wells installed to 1 m depth below the feature from September 1, 2016 to May 1, 2017 are also presented. Fodar orthoimages and DEM data from April 2017 and September 2017 are included, as well as ice thickness estimated from the difference in these DEMs.
