Mapping Global GNSS Vertical Velocities to Solid Earth Figure Change

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract The Earth's figure evolves in response to glacial isostatic adjustment (GIA), surface‐mass redistribution, and rotational and mantle‐driven processes. While temporal changes in the geoid's flattening are monitored through low‐degree gravity field harmonics, the geometric response of the solid Earth can be assessed independently from GNSS ...

Decadal‐Scale Bathymetric Change in a Shallow Coastal Bay

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract Coastal marshes and bays must accumulate sediment to maintain their position relative to mean sea level during periods of sea level rise (SLR). Resuspension of bay‐bottom sediment, which together with tidal inundation promotes marsh deposition, is sensitive to water depth, but quantitative measurements of bathymetric change across shallow bays

Satellite data reveal details of glacial isostatic adjustment in the Amundsen Sea Embayment, West Antarctica [PDF]

The Cryosphere
The instability of the West Antarctic Ice Sheet (WAIS) is a tipping element in the climate system, and it is mainly dictated by changes in the ice flow behaviour of the outflow glaciers in the Amundsen Sea Embayment (ASE).

Sea‐Level Change in Hong Kong From Tide Gauges, GNSS, and Satellite Altimetry

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract As a densely populated, highly urbanized coastal city, Hong Kong is particularly vulnerable to sea‐level rise, which amplifies flood risk and threatens coastal infrastructure, economies, and ecosystems. We combine observations from tide gauges, conventional gridded satellite altimetry, coastal‐retracked altimetry, and Global Navigation ...

Tracking Deep Mantle Melting on Mars Using Phobos Tides

Journal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.
Abstract We study the deep internal structure and rheological state of Mars by analyzing its response to tidal forces exerted by Phobos and by introducing a melt fraction in the mantle layers. Motivated by recent seismic evidence for a basal molten layer near the base of the Martian mantle, we explore the distribution of melt within the mantle and its ...

Effects of Andrade and Burgers rheologies on glacial isostatic adjustment modeling in Antarctica

Geodesy and Geodynamics
Variations in ice mass deform the Earth and modify its gravity field, a process known as Glacial Isostatic Adjustment (GIA). GIA in Antarctica remains poorly constrained due to the cumulative effect of past and present ice-mass changes, the unknown ...

Statistical analysis of the acceleration of Baltic mean sea-level rise, 1900-2012

Frontiers in Marine Science, 2016
We analyse annual mean sea-level records from tide-gauges located in the Baltic and parts of the North Sea with the aim of detecting an acceleration of sea-level rise over the 20textsuperscript{th} and 21textsuperscript{st} centuries.

Dominant Glacial Control on Plio‐Pleistocene to Recent Exhumation of the Kyrgyz Range (Tien Shan)

Tectonics, Volume 45, Issue 9, September 2026.
Abstract The evolution of mountain ranges results from complex interactions between tectonics and climate, yet their relative contributions to exhumation can be difficult to discern. Previous thermochronological studies in the Kyrgyz Range (Tien Shan) attributed late Cenozoic rapid exhumation primarily to increased tectonic shortening without ...

Constraining Glacial Isostatic Adjustment with Horizontal GPS Velocities in Antarctica

, 2017
Glacial isostatic adjustment is the viscoelastic response of the Earth to ice and ocean loads. In forward models of glacial isostatic adjustment, mantle viscosity is often assumed to be laterally homogeneous.
