Candidates for volcanoes under the ice of Antarctica detected by their gravito-topographic signal

[摘要] We analyse the newest gravity field models (given in the form of spherical harmonic expansion to degree and order 2190) EIGEN 6C4 and RET 14, which consist basically from the gravity data from EIGEN 6C4 plus the bedrock topography from the Bedmap 2 model,
