Isostatic stability of the East Antarctic station Dumont d'Urville from long-term geodetic observations and geophysical models
International audience Geodetic measurements of the vertical crustal displacement collocated with absolute gravity changes provide a discriminatory measurement of present-day glacial changes, versus more deeply seated rock motions caused by glacial isostatic adjustment (GIA). At the East Antarctic s...
