Mount Brown Antarctica climate record



An Antarctic climate record from Mount Brown, East Antarctica.

Centre for Ice and Climate has been invited to partner with the Australian Antarctic Division, to produce a new 2000-year detailed climate record from a never-before-studied location in coastal East Antarctica. The Mt Brown South climate record will demonstrate how climate is changing in the Indian Ocean basin as well as constraining the impact of anthropogenic climate change across Antarctica and this poorly understood region of the Southern Hemisphere.

Along the 8000 km coastline of East Antarctica only one such record is available, from Law Dome (Longitude 112°E, south of Australia). To improve the geographical coverage of Antarctic climate records, a comprehensive climate record from Mt Brown in coastal East Antarctica (85°E) will be produced using both ice core and borehole analysis. Key parameters to be reconstructed include past temperature, snow accumulation, snow/moisture source and sea ice variability.

The chief investigator of the Mount Brown South project is Dr Tessa Vance (Antarctic Climate & Ecosystems Cooperative Research Centre (ACE CRC)). Dr Paul Vallelonga (University of Copenhagen) is the leader of the Danish contribution to the project funded by the Carlsberg Foundation.

The Mt Brown South ice core drilling will use the Danish Hans Tausen (http://recap.nbi.ku.dk/facilities/) intermediate drill system which has been successfully used in previous drilling projects at Renland ice cap (http://recap.nbi.ku.dk) in Greenland and Aurora Basin (http://www.antarctica.gov.au/science/climate-processes-and-change/antarctic-palaeoclimate/aurora-basin) in Antarctica.
