Holocene climate history obtained from snow profiles (chemistry, dust flux, temperature, structure), firn cores and climate measurements from the Wilson Piedmont Glacier, Victoria Land Coast, Antarctica
Abstract:
To understand the drivers and consequences of climate change on timescales important to humans, the paleoclimate of ice cores, the glacial system and local climate patterns were analysed from the Wilson Piedmont Glacier. The Wilson Piedment Gacier serves as a reference record for an examination of the Victoria Lower Glacier. During the 00-01 season a 3m snow profile was sampled in 1cm resolution ... for major ion content, isotope ratios and in 5cm resolution for dust flux and beta radioactivity analyses. Temperature, crystal geometry and density were measured on site. A shallow (23m) firn core was recovered from the glacier and analysed for crystal structure, melt and dust layers analysis. Borehole temperatures were measured. The glacier topography was measured using differential static GPS. Six hourly weather observations were also taken.
