Information - BG7.02 Exploration of Sub-Glacial Lake Environments and Ecosystems
Subglacial lakes have been a subject of keen research interest for the past decade, following the remarkable discovery of the giant subglacial Lake Vostok beneath 5 kilometres of Antarctic ice sheet. Over a hundred other such lakes have since been identified and remote geophysical studies have yielded intriguing data as to the environmental features of these systems and interaction with both the overlying ice sheet and underlying geology whilst high resolution molecular microbiology and geochemical modelling indicate the likely presence of microbial life and biogeochemical processes. Substantial links to ongoing research on astrobiology and the evolution of life on Earth have developed and there is great interest in the possibility of there being historical records in the sediments of these lakes. Plans are developing to penetrate and sample a number of subglacial lakes over the coming decade and this session will provide the opportunity to update EGU on these emerging initiatives and to outline the current status of knowledge of subglacial environments.
