- Abstract:
- Ice at the bottom of the Vostok ice core originates from waters of Lake Vostok, the largest of the many lakes beneath the Antarctic ice sheet. The chemical composition of this bottom ice is variable, suggesting that Lake Vostok too has had a variable chemical composition in the past. The most likely explanation for this observation is that the Lake has expanded and contracted as the Antarctic Ice Sheet grows and contracts over cycles of glaciation. However, small particles found in the bottom ice may interact with the ice during laboratory procedures. The project first assesses how much of the chemical variation is due to interactions with these particles, then examines the likely glaciological reasons for any chemical variation that cannot be explained otherwise.
