Glacial history of sub-Antarctic South Georgia based on the submarine geomorphology of its fjords (2014)

We present multibeam swath bathymetric surveys of the major fjords surrounding the sub-Antarctic island of South Georgia to characterise the glacial geomorphology and to identify the relative timings and extent of past glacial advance and retreat. Ba... Read More about Glacial history of sub-Antarctic South Georgia based on the submarine geomorphology of its fjords.

Rapid Thinning of Pine Island Glacier in the Early Holocene (2014)
Journal Article
Johnson, J., Bentley, M., Smith, J., Finkel, R., Rood, D., Gohl, K., …Schaefer, J. (2014). Rapid Thinning of Pine Island Glacier in the Early Holocene. Science, 343(6174), 999-1001. https://doi.org/10.1126/science.1247385

Pine Island Glacier, a major outlet of the West Antarctic Ice Sheet, has been undergoing rapid thinning and retreat for the past two decades. We demonstrate, using glacial-geological and geochronological data, that Pine Island Glacier (PIG) also expe... Read More about Rapid Thinning of Pine Island Glacier in the Early Holocene.

This paper presents a glacial geomorphological map of the landforms created by five large ice lobes that extended eastwards from the southernmost reaches of the Patagonian Ice Sheet during the Quaternary period. The study is focussed on Tierra del Fu...
