UGA researchers discover fate of melting glacial ice in Greenland
UGA researchers melting glacial ice Greenland
2016/5/6
Over the past several decades, scientists have observed a significant increase in the melting of glacial land ice on the island of Greenland, spurring concerns about global sea level rise and the long...
Thermo-hydro-mechanical processes in fractured rock formations during a glacial advance
Thermo-hydro-mechanical processes fractured rock formations glacial advance
2015/8/6
The paper examines the coupled thermo-hydro-mechanical (THM) processes that develop in a fractured rock region within a fluid-saturated rock mass due to loads imposed by an advancing glacier. This sce...
Deep Ocean Carbonate Chemistry and Glacial-Interglacial Atmospheric CO2 Changes
Deep Ocean Carbonate Chemistry Glacial-Interglacial Atmospheric CO2
2015/7/17
Changes in deep ocean carbonate chemistry have profound implications for glacial-interglacial atmospheric CO2 changes. Here, we review deep ocean carbonate ion concentration ([CO32–]) changes based on...

Seismic Stratigraphic evidence antarctica
2015/7/15
Seismic stratigraphic and drill data from Antarctic continental
margins have provided much direct evidence concerning ice sheet evolution as
Earth’s climate cooled from the warmth of the Eocene. S...
Backward-moving glacier helps scientists explain glacial earthquakes
Backward-moving glacier scientists glacial earthquakes
2015/7/13
New insight into glacier behaviour will improve our ability to predict future sea-level rise in a warming climate.The relentless flow of a glacier may seem unstoppable, but now a team of UK and US res...
In 2008 scientists from Woods Hole Oceanographic Institution (WHOI) and the University of Washington documented for the first time how the icy bottoms of lakes atop the Greenland Ice Sheet can crack o...
PALEOPRODUCTIVITY VARIATIONS IN THE EASTERN CENTRAL EQUATORIAL PACIFIC OCEAN ON GLACIAL TIMESCALES
Nutrients Phosphorus Cycle Glacial-Interglacial Sea Level
2015/1/16
Paleoproductivity records during the late Pleistocene are sparse. The equatorial Pacific and the Southern Ocean are collectively responsible for the majority of the new production in the oceans. The n...
Comparing a thermo-mechanical Weichselian Ice Sheet reconstruction to reconstructions based on the sea level equation: aspects of ice configurations and glacial isostatic adjustment
thermo-mechanical Weichselian Ice Sheet reconstruction to reconstructions sea level equation ice configurations glacial isostatic adjustment
2015/1/6
In this study we compare a recent reconstruction of the Weichselian Ice Sheet as simulated by the University of Maine ice sheet model (UMISM) to two reconstructions commonly used in glacial isostatic ...
Lithosphere and upper-mantle structure of the southern Baltic Sea estimated from modelling relative sea-level data with glacial isostatic adjustment
Lithosphere and upper-mantle structure southern Baltic Sea estimated modelling relative sea-level data glacial isostatic adjustment
2015/1/6
During the last glacial maximum, a large ice sheet covered Scandinavia, which depressed the earth's surface by several 100 m. In northern central Europe, mass redistribution in the upper mantle led to...
Optimal locations of sea-level indicators in glacial isostatic adjustment investigations
Optimal locations sea-level indicators glacial isostatic adjustment
2015/1/6
Fréchet (sensitivity) kernels are an important tool in glacial isostatic adjustment (GIA) investigations to understand lithospheric thickness, mantle viscosity and ice-load model variations. These par...
Effect of glacial-interglacial sea-level changes on the displacement and stress field in the forearc and along the plate interface of subduction zones
glacial-interglacial sea-level stress
2015/1/4
Combined seismological, space-geodetic and numerical studies have shown that the seismicity at subduction zones may be modulated by tides and glacier fluctuations on timescales of 1–100 a, becau...

A new coupled ice sheet/climate model: description and sensitivity to model physics under Eemian, Last Glacial Maximum, late Holocene and modern climate conditions
A new coupled ice sheet climate model description and sensitivity to model physics Eemian Last Glacial Maximum late Holocene modern climate conditions
2014/12/9
The need to better understand long-term climate/ice sheet feedback loops is motivating efforts to couple ice sheet models into Earth System models which are capable of long-timescale simulations. In t...
