An initial intercomparison of atmospheric and oceanic climatology for the ICE-5G and ICE-4G models of LGM paleotopography [PDF]
, 2005 This paper investigates the impact of the new ICE-5G paleotopography dataset for Last Glacial Maximum (LGM) conditions on a coupled model simulation of the thermal and dynamical state of the glacial atmosphere and on both land surface and sea surface ...

The first-order effect of Holocene Northern Peatlands on global carbon cycle dynamics [PDF]
, 2010 Given the fact that the estimated present-day carbon storage of Northern Peatlands (NP) is about 300–500 petagram (PgC, 1 petagram = 1015 gram), and the NP has been subject to a slow but persistent growth over the Holocene epoch, it is desirable to ...

The influence of atmospheric grid resolution in a climate model-forced ice sheet simulation [PDF]
The Cryosphere, 2018 Coupled climate–ice sheet simulations have been growing in popularity in recent years. Experiments of this type are however challenging as ice sheets evolve over multi-millennial timescales, which is beyond the practical integration limit of most ...

Exploring the use of zircon geochronology as an indicator of Laurentide Ice Sheet till provenance, Indiana, USA [PDF]
, 2017 A pilot study was designed to evaluate the potential of zircon geochronology as a provenance indicator of till from the Lake Michigan, Saginaw, and Huron-Erie Lobes of the Laurentide Ice Sheet. Based on existing ice flow-path models, we hypothesized that

Modelling binge–purge oscillations of the Laurentide ice sheet using a plastic ice sheet [PDF]
Annals of Glaciology, 2008 AbstractA simple combined heat and ice-sheet model has been used to calculate temperatures at the base of the Laurentide ice sheet. We let the ice sheet surge when the basal temperature reaches the pressure-melting temperature. Driving the system with the observed accumulation and temperature records from the GRIP ice core, Greenland, produces surges ...

Role of sediments in controlling the dynamics of paleo-ice sheets [PDF]
, 2017 The motion of glacial ice is predominantly controlled by basal conditions, which include a variety of parameters such as ice rheology, temperature, water content, the presence of sediments, and topography.

Isostatic Recovery and the Strain Rate Dependent Viscosity of the Earth's Mantle [PDF]
, 1974 This paper is concerned with the interpretation of isostatic recovery data in terms of the flow properties of the earth's mantle. A hydrodynamic analysis is first presented that allows straightforward calculation of the relaxation time for isostatic ...

Permafrost and Periglacial Processes, EarlyView.ABSTRACT Across circumpolar permafrost regions, climate change is destabilizing ice‐rich hillslopes, increasing the frequency and magnitude of thaw‐driven mass wasting. This paper reviews recent studies (2013–2024) on thaw‐driven mass wasting, focusing on the processes, morphology and trajectories of geomorphic change and their implications for ...

Interdependence of the growth of the Northern Hemisphere ice sheets during the last glaciation: the role of atmospheric circulation [PDF]
Climate of the Past, 2014 The development of large continental-scale ice sheets over Canada and northern Europe during the last glacial cycle likely modified the track of stationary waves and influenced the location of growing ice sheets through changes in accumulation and ...
