On deglaciation-induced perturbations of the geoid [PDF]
Canadian Journal of Earth Sciences, 1986 The importance of geoid perturbations in interpreting tilts of glacial lake levels is investigated, using a representative theoretical model. It is shown that near the ice margin, the slope of the Earth's perturbed surface is everywhere large compared with the slope of the associated undulation of the geoid. Perturbations of the geoid may therefore be

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.Abstract Estimating relative sea level rise, which measures changes in sea level compared to the land where people live, is crucial for the Ayeyarwady Delta, home to 15 million residents on this low‐lying delta. Like many large deltas, the Ayeyarwady Delta should experience subsidence from its own weight, worsening the effects of sea level rise ...

Precise geoid computation using Stokes-Helmert's scheme and strict integrals of topographic effects
Geodesy and Geodynamics, 2019 The high-precision local geoid model was computed based on the improved Stokes-Helmert′s boundary value problem and strict integrals of topographic effects. This proposed method involves three steps.

Post‐1990s Warming of Circumpolar Deep Water Off West Antarctica and Its Drivers
Journal of Geophysical Research: Oceans, Volume 131, Issue 7, July 2026.Abstract Ice loss off East Antarctica has been linked to the warming of Circumpolar Deep Water (CDW) associated with a poleward shift of the southern boundary of the Antarctic Circumpolar Current (ACC). In West Antarctica, where the fastest ice‐shelf melting occurs, it has been proposed that off‐shelf CDW warming could be additionally driven by ...

Eos, Transactions American Geophysical Union, 1989 The International Geoid Commission was formed by the International Association of Geodesy at the 19th General Assembly of the IUGG in Vancouver, 1987. The commission operates as Commission XII of Section III (Determination of the Gravity Field) of IAG.A Commission of the IAG considers those activities for which close international cooperation or ...
