Using sea-level and land motion data to develop an improved glacial isostatic adjustment model for the British Isles
The Glacial Isostatic Adjustment (GIA) of the British Isles is of interest due to the constraints that can be provided on key model parameters such as regional ice sheet history, viscoelastic earth structure and the global meltwater (eustatic) signal. Many past studies have used as their primary …

Glacial isostatic adjustment and relative sea level change over the last earthquake cycle in upper Cook Inlet, Alaska, USA
… to post Little Ice Age (AD 1200 – 1900) glacial isostatic adjustment, with a spatial signal over tens of kilometres. A set of viable Earth models, constrained by GPS data and the pattern of post-seismic displacement quantifies the relative displacement and deformation of the ocean geoid …

The evolution of the Greenland Ice Sheet from the Last Glacial Maximum to present-day: An assessment using glaciological and Glacial Isostatic Adjustment modelling
… ice sheet (GrIS) evolution from the Last Glacial Maximum (LGM, 21 ka BP) to the present-day using, primarily, observations of relative sea level (RSL) as well as field data on past ice extent. The new model (Huy2) fits a majority of the observations and is characterised by a number of key …

On the Viscoelastic Deformation of the Earth
Post-seismic deformation and glacial isostatic adjustment are two processes by which the Earth deforms viscoelastically. In both cases, the details of the deformation depend on the rheological structure of the Earth as well as the forcing, which is the earthquake and further movement on the fault …

Geodetic and Geodynamic Constraints on Vertical Land Motions in the Chesapeake Bay
… the Chesapeake Bay are dynamic topography and glacial isostatic adjustment. We perform geodynamic modeling to assess the influence of both processes on the region. We estimate present-day rates of dynamic topography using ASPECT (Advanced Solver for Planetary Evolution, Convection, and …

NUMERICALLY MODELING FLOODING SUSCEPTIBILITY OF THE UNITED STATES NAVAL ACADEMY
… is especially impacted by urban flooding. Due to glacial isostatic adjustment and reclaimed soil consolidation, this area experiences subsidence as well as the effects of sea level rise, which make it susceptible to urban flooding. As the frequency of these flooding events increases, there is an …

Modelling Sea-Level Reconstructions from Southern Greenland: Implications for Glacially-Induced Faulting
… mean sea level rise. Data and models related to glacial isostatic adjustment (GIA) have provided critical constraints on past GrIS evolution. These models are necessary to interpret a variety of data, including past sea-level changes and geodetic observations of current land motion and gravity …

GPS Imaging of Vertical Land Motion and Earthquake Coseismic Displacements in the GPS Mega-Network
… signal concentrated around the Cascadia arc. Glacial isostatic adjustment modeling of the region determined that lithospheric flexure contributes about -1 mm/year of subsidence to the region. By combining the postseismic relaxation and glacial isostatic adjustment models, the subsidence …

Observing Drought-Induced Crustal Loading Deformation Around Lake Mead Region via GNSS and InSAR: A Comparison With Elastic Loading Models
… signal. To achieve this, I remove the effects of glacial isostatic adjustment and non-tidal mass loads from GNSS/InSAR observations. Our findings indicate that recent drought periods led to a notable uplift near Lake Mead, averaging 7.3 mm/year from 2012 to 2015 and an even larger rate of 8.6 …

Dynamic Topography of Madagascar and its Surroundings
… intermediate terrace is dated to the last interglacial period using U-series techniques ($130.7\pm13.2$~ka). A tilt in terrace elevations from 9.3--2.8~m cannot be explained by glacial-isostatic adjustment. Instead, growth of a dynamic topographic swell may have tilted the land surface during …

Intermontane valley fills
