VUW
The principal objectives of this season's work were as follows:
1) | to complete geological mapping of the Sirius Group at Allan Hills begun during the 1998-1999 season |
2) | to study deposits of the Sirius Group for the purpose of interpreting the nature of the ice that deposited it |
3) | to select sites for drilling to be conducted during 2000-2001 season |
Univ. of Amsterdam
1) | Build upon research carried out by Hiemstra and van der Meer (1999) in their field report for the Netherlands Centre for Geo-ecological research titled: Neogene Glacial History of the Allan Hills, South Victoria Land, Antarctica. This would include quantification of Sirius related glacio-tectonic bedrock deformation structures and further descriptions and sketches. |
2) | Collect spatially and stratigraphically variable Sirius diamict samples for analyses by micromorphology. Wherever these micromorphology samples are taken, a small sample will also be taken for bulk texture analysis. Determine whether this is possible with a University of Amsterdam hand held drill or by simply removing a block of diamict using a chisel and geological hammer. |
3) | Describe, sketch and quantify glacio-tectonic deformation of bedrock related to a recent advance of the Manhaul glacier. Collect spatially variable samples of Manhaul glacial diamict associated with the glacio-tectonic deformed bedrock for analysis by micromorphology. Wherever these micromorphology samples are taken, a small sample will also be taken for bulk texture analysis. |
4) | Collect samples of 'sublimation till' from the snout of Taylor glacier and Suess glacier, Taylor Valley for analysis by micromorphology. |
5) | Collect samples from the debris-laden basal layer of Taylor glacier itself for micromorphology analysis. |
6) | Determine the practicality of undertaking pre-impregnation of unconsolidated sediments in the Antarctic field, with daily temperatures considerably below zero. |
