A geodynamically consistent 3D mantle viscoelastic model with a weak asthenosphere and temperature-dependent viscosity matches both GNSS crustal motions and GRACE gravity changes in West Antarctica.
- Why it matters: Rapid ice loss since the 1990s has altered surface elevation, uplift, and gravity, but explaining these signals requires viscoelastic Earth properties tied to deglaciation history.
- What they did: The study built GIA models using a reconstructed Antarctica ice history from 1900–2020 and geodynamically consistent 3D mantle structures, fitting GNSS crustal motion and GRACE gravity observations in West Antarctica.
- The result: The joint fit supports a mantle rheology that is consistent with million-year mantle convection and ongoing decadal GIA in West Antarctica.
