Project information
Project aim
The climate variability of the Southern Ocean sector of the circum-Antarctic and East Antarctic is being investigated using ice core studies. Ice cores retrieved from 100 m deep boreholes in Wilkes Land, East Antarctica, will provide a 200-300 year archive of climate history. The project will produce data on the history of atmospheric circulation in the Southern Ocean sector of the circum-Antarctic, associated with the Antarctic Circumpolar Wave (ACW) and the El Nino Southern Oscillation (ENSO) and the Southern Annular Mode of climate variability. The proxy climate data on surface temperature, frequency of precipitation events, snow accumulation rates, moisture source, strong katabatic wind events, and atmospheric blocking south of eastern Australia, will be combined with instrumental meteorological records to understand the mechanisms controlling the interaction between atmospheric circulation between south-east Australia and Antarctica. The project will form a component of the International Trans Antarctic Scientific Expedition (ITASE).

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.

Category 3: Verbal presentation
Coastal Antarctic sea salt aerosols are partitioned into two main sources, namely ocean sea spray and surface sea ice. The sea spray source is related to windiness over the surface ocean and the action of bubbles bursting.
