has occurred as a consequence of changes in the seasonal insolation regime forced by the influence of gravitational n-body effects in the Solar System on the geometry of Earth's orbit around the Sun. The impacts of the changing surface ice load upon both Earth's shape and gravitational field...
Glacial isostasy refers to the response of the solid Earth to any changes in the planet's ice sheets. The Earth is not a rigid body and it will deform when subjected to forces or to changes in surface loads. The nature of this deformation depends largely on the time scale, magnitude, ...

When parts of an ice sheet–subsurface interface becomes warm based, groundwater recharge from basal melting may take place. In addition, surface melting during the warm seasons yields substantial meltwater rates that can reach the ice sheet–subsurface interface through crevasses or moulins, ...

The LGM Laurenticle ice sheet. predicted to develop in response to orbital climate forcing, is such that the ratio of its thickness to its horizontal extent is extremely large compared to the aspect ratio inferred on the basis of surface-geomorphological and solid-earth-geophysical constraints. We...

Why are we researching the Petermann Glacier system? Ice is generally thought of as a solid, and one might imagine that an ice sheet is much like icing on a slab of yellow cake – a static layer, softening and melting away at its edges as the surrounding

Glacial landform, any product of flowing ice and meltwater. Such landforms are being produced today in glaciated areas, such as Greenland, Antarctica, and many of the world’s higher mountain ranges. In addition, large expansions of present-day glaciers
