Rivera, A., Bown, F., Carrión, D., Zenteno, P. (2012) : "Glacier response to recent volcanic activity in Southern Chile." Environmental Research Letters, , 7, doi:10.1088/1748-9326/7/014036..

Glaciers in Southern Chile (39–43°S) are characterized by frontal retreats and area losses in response to the ongoing climatic changes at a timescale of decades. Superimposed on these longer-term trends, volcanic activity is thought to impact glaciers in variable ways. Debris–ash covered Glaciar ...

Tidewater calving glaciers can undergo large fluctuations not necessarily in direct response to climate, but rather owing to complex ice–water interactions at the glacier termini. One example of this process in Chilean Patagonia is Glaciar Jorge Montt, where two cameras were installed in February...

Whalley & J. Woodward (2011) : "Probe Technology for the Direct Measurement and Sampling of Ellsworth Subglacial Lake" Antarctic Subglacial Aquatic Environments, 159-186.

The direct measurement and sampling of Ellsworth Subglacial Lake is a multidisciplinary investigation of life in extreme environments and West Antarctic ice sheet history. The project's aims are (1) to determine whether, and in what form, microbial life exists in Antarctic subglacial lakes and (2...

Woodward (2011) : "Ellsworth Subglacial Lake, West Antarctica: A Review of Its History and Recent Field Campaigns" Antarctic Subglacial Aquatic Environments, 221-233.

Ellsworth Subglacial Lake, first observed in airborne radio echo sounding data acquired in 1978, is located within a long, deep subglacial trough within the Ellsworth Subglacial Highlands of West Antarctica. Geophysical surveys have characterized the lake, its subglacial catchment, and the thickn...

Hypsometry describes the distribution of elevation of land with respect to sea level within an area of interest, with positive values being above sea level and negative values below sea level ...

We analyze Holocene ice flow using global positioning system and radio-echo sounding data acquired near the Amundsen-Weddell ice divide, between Pine Island Glacier and the Institute Ice Stream, West Antarctica. The data show that this part of the West Antarctic Ice Sheet (WAIS) has maintained a ...
