About the Project
Fluctuations in ice extent in response to climate exposes previously buried bedrock slopes to non-glacial processes of erosion. These newly de-buttressed slopes, based on non-polar conceptual models, are thought to be highly unstable and though the combined processes of rockfall and landsliding deliver debris to ice surfaces. This debris is ultimately transported to the ocean sediment store, although some is stored at the base of slopes until ice thickens again and is able to transport it.
Landslides in Antarctica range from small individual rockfall, rapid long-runout rock avalanches millions of cubic meters in volume, through to the slow failure of entire mountainsides with volumes measured in cubic kilometres. However, we have no information on the rates and spatial patterns of activity, nor how these may vary in response to current, and by inference, past climate change. Current rapid rates of warning over the Antarctic Peninsula, combined with the established patterns of ice change and isotactic uplift make it an ideal location to quantify hillslope processes and the sediment flux to glaciers as ice retreats and/or thins.
There is an archive of aerial photography of the Antarctic Peninsula dating back to the 1940s that has been largely ignored due to the range of technical problems associated with deriving quantitative data from historic aerial photographs. Advances in photogrammetric processing and capture of modern aerial photography have allowed this archive to be ’unlocked’. This project will process archive aerial imagery, and use historic and modern ground-based imagery to quantify multi-scale landslide activity in Antarctica.
