Reply to Uxa (2016) Discussion on Active Layer Thickness Prediction on the Western Antarctic Peninsula by Wilhelm et al. (2015)
Uxa () used alternative assumptions to calculate active‐layer thicknesses (ALTs) on Amsler Island, Western Antarctic Peninsula, and concluded that assumptions in Wilhelm et al. () overestimate ALTs in the region. Here, we accept that the core of his argument is correct, but we contend that observati...
