Metadata details

ASAC_1332

All scientific data collected by the Australian Antarctic program (AAp) are eventually described in the Catalogue of Australian Antarctic and Subantarctic Metadata (CAASM). CAASM can be used to search through AAp data descriptions, and it also provides links to access publicly available datasets, which can either be immediately downloaded or obtained from the Australian Antarctic Data Centre (AADC).

    Description

    Geological evidence from the Framnes Mountain, East Antarctica, will reveal changes in ice thickness from the Last Glacial Maximum 20,000 years ago to the present. A computer simulation of changes in ice thickness will show how the ice sheet interacts with climate and sea level, which is important for predicting future changes.

    Cosmogenic isotope samples were taken from 29 locations including Welch Island (1 sample), Mawson area (1 sample), Mt Henderson area (7 samples), and the northern (13 samples), central (3 samples) and southern (2 samples) Masson ranges. No samples were taken from the Casey Range or the David Range (with the exception of the Mt Hordern area (2 samples). Mapping of the glacial geology was undertaken - few trimlines were evident and moraines where present consisted dominantly of local lithologies. The glacial clasts sampled for cosmogenic isotope analysis were felsic erratics perched on or near to stable hilltop surfaces, with clear sky exposure (conditions ideal for cosmogenic isotope dating).

    Sediment analyses to support interpretations of the glacial history are being undertaken in 2004-2005.

    Quality

    Cosmogenic isotope analyses - The samples taken were almost uniformly of a high quality (conditions ideal for cosmogenic isotope dating). Details of the dating undertaken will be posted once sample processing has occurred and accelerator targets have been run.

    Sedimentology - will consist of grain size analyses (Malvern laser sizer and settling tube), elemental analyses (XRF) and clay fraction analysis (XRD) to be made public domain following thesis production at start of 2006.

    Surface weathering - data were collected according to the Moriwaki scheme.
