Scale-dependence of lithological control on topography: Bedrock channel geometry and catchment morphometry in western Scotland [PDF]
We propose that a scale-dependent topographic signature of erodibility arises due to fluvial and glacial erosion acting on different parts of the landscape at different times.

Glacial isostatic adjustment (GIA) represents a source of uncertainty for ice sheet mass balance estimates from the Gravity Recovery and Climate Experiment (GRACE) time-variable gravity measurements.

A dynamic continental runoff routing model applied to the last Northern Hemisphere deglaciation [PDF]
We describe and evaluate a dynamical continental runoff routing model for the Northern Hemisphere that calculates the runoff pathways in response to topographic modifications due to changes in ice thickness and isostatic adjustment.

Observed crustal uplift near the Southern Patagonian Icefield constrains improved viscoelastic Earth model [PDF]
Thirty‒one GPS geodetic measurements of crustal uplift in southernmost South America determined extraordinarily high trend rates (> 35 mm/yr) in the north‒central part of the Southern Patagonian Icefield.

Glacial-Isostatic Adjustment-I. The Forward Problem [PDF]
Summary The isostatic adjustment of a radially stratified visco-elastic spheroid is treated using space-time Green functions for the associated surface mass load boundary value problem. These impulse response functions are convolved with a Heaviside function to give the time dependent deformation of the planet which would be produced by a unit point

Late Glacial to Holocene relative sea-level change in Assynt, northwest Scotland, UK [PDF]
Relative sea-level change (RSL), from the Late Glacial through to the late Holocene, is reconstructed for the Assynt region, northwest Scotland, based on bio- and lithostratigraphical analysis.

On the gravity and geoid effects of glacial isostatic adjustment in Fennoscandia - a short note
Many geoscientists argue that there is a gravity low of 10-30 mGal in Fennoscandia as a remaining fingerprint of the last ice age and load, both vanished about 10 kyr ago.

ICESHEET 1.0: a program to produce paleo-ice sheet reconstructions with minimal assumptions [PDF]
We describe a program that produces paleo-ice sheet reconstructions using an assumption of steady-state, perfectly plastic ice flow behaviour. It incorporates three input parameters: ice margin, basal shear stress and basal topography.

Towards Constraining Glacial Isostatic Adjustment in Greenland Using ICESat and GPS Observations [PDF]
Constraining glacial isostatic adjustment (GIA) i.e. the Earth’s viscoelastic response to past ice changes, is an important task, because GIA is a significant correction in gravity-based ice sheet mass balance estimates. Here, we investigate how temporal

Alternating seismic uplift and subsidence in the late Holocene at Madang, Papua New Guinea: Evidence from raised reefs [PDF]
Well-preserved mid-late Holocene coral reefs are exposed in low coastal cliffs in the vicinity of the Madang lagoon on the north coast of Papua New Guinea.
