Project information
Project aim
The Antarctic ice sheet is comprised of accumulated snowfall events, and thus preserves atmospheric information (e.g. temperature, atmospheric composition, storminess, volcanic influences etc) at the time of snowfall. The aim of ice core drilling in polar regions is to extract information which aids in the reconstruction of past climatic conditions, which in turn can be used in models to predict future conditions. There has been limited research, however, towards calibrating records preserved in the ice sheet with atmospheric conditions. The intention of this project is to examine the extent to which chemical records can be explained by observed meteorological conditions. This will involve a detailed study of the individual snowfall events in the upper few meters of snow and comparisons with observed meteorological conditions during those events. The findings of this study will contribute to the understanding of the processes influencing snowfall at Law Dome, and improve the interpretation of the records from the deeper cores.

A compilation of sea salt data from East Antarctic ice cores are used to quantify the contribution of open ocean and sea ice to the sea salt budget. The ice cores used in this study are from Law Dome, Totten Glacier, Wilkes Land and Wilhelm II Land.
