Crustal thicknesses in Antarctica from Sp receiver functions

This dataset contains crustal thickness measurements at 99 individual broadband seismic stations across Antarctica derived from teleseismic Sp waves. Crustal thickness estimates were obtained by measuring the depth of the Sp phase associated with the crust-mantle boundary observed in single-station stacks of Sp receiver functions. The measurements offer new constraints on crustal structure in West and East Antarctica. Comparison with crustal thickness estimates from prior studies are provided in the associated journal article (see References).
