Luminescence dating of marine and fluvial sediments from Bunger HillsEntry ID: ASAC_2237
Abstract: Metadata record for data from ASAC Project 2237
See the link below for public details on this project.
Two excel spreadsheets are available for download from the provided URL.
Taken from the 1997-1998 Progress Report for this project:
INAA (instrumental neutron activation analysis) analyses have been made of subsamples of each OSL (Optically stimulated luminescence) sample, for dosimetry ... calculation. The samples were then dated at Royal Holloway, University of London (RHUL) which is the worlds leading lab for this work.
Two very significant findings were made: (i) That the OSL technique works, and is reliable in Antarctica. These are the first OSL dates from Antarctica; (ii) The overriding hypothesis of Colhoun et al. (ASAC 926) has been vindicated: that Bunger Hills was not fully glaciated at the last glacial maximum.

Paleo Temporal Coverage
Paleo Start Date: 45 ka bp
Latitude Resolution: 30 m
Longitude Resolution: 30 m
Quality The field samples were located using a satellite image map and a Russian topographic map, and are estimated to be plus or minus 30 metres of any given grid reference. The OSL data were generated from the RLAHA (Research Laboratory for Archaeology and History of Art) at Keble Road Oxford, under Dr Ed Rhodes.
However, the data available for download are only "geochemistry for sample dosimetry" provided by Damian Gore. The quality of the spreadsheets are poor as they have not been adequately explained.
