Accurate knowledge of the Antarctic ice sheet mass
balance plays an important role on the global sea
level change. Here two-pass differential InSAR
(DInSAR) technique is applied for tidal signal
modeling underneath the Sulzberger ice shelf, West
Antarctica. The fine resolution DEM over grounded
ice and ice shelf, obtained by combining ERS-1/2
tandem InSAR and ICESat laser altimetry, has been
used to correct the topography phase from
interferograms, resulting in a more accurate time
series of vertical deformation measurements. In this
study, it is demonstrated for the first time,...
