Antarctic Moho Compilation of AN-Moho

We collected crustal thickness and/or Moho depth data from previous seismic studies (not including surface wave studies), and made a compilation of ANtarctic Moho positions (AN-Moho), under the evaluation of the quality of Moho depths. Considering that the crustal thickness or Moho depth given in previous studies may be variably defined, we corrected all thickness data to the same crustal thickness definition. Therefore, slight differences are evident between the data of our AN-Moho as compared with previous compilations and also data presented in previous studies because of different definitions.

Moho depths in the compilation of AN-Moho for Antarctica is shown in Figure 1 (= Figure 4 in An et al. [2015a]). All the Moho depths and the previous studies that the Moho depths come from are listed in Table 1 (= Table S1 in An et al. [2015a]). It is noted that the Moho depth in Table 1 is from sea level to the Moho discontinuity, but crustal thickness is from the solid surface. More details of how this compilation was constructed can be found in a supplementary section to:
