项目摘要
Antarctic subglacial lakes are expected to contain unique microbial lifeforms and detailed records of past climate change. Examination of these contents requires in-situ measurement, which can only take place once a lake has been characterised fully by geophysical methods. Of the 101 known subglacial lakes in Antarctica none have been measured to the level required for meaningful direct sampling to take place. This proposal aims to undertake a comprehensive geophysical exploration of a 10 km ong subglacial lake in West Antarctica (near the Ellsworth Mountains). Data analysis and modelling will be undertaken at the University of Bristol, the British Antarctic Survey and Northumbria University.Ice thickness will be determined from ice-penetrating radar, water depths will be found using seismic exploration, and ice flow and accumulation will be obtained from direct surface measurements. A series of numerical models will be used to understand the history of the lake, the flow of ice across the lake and the circulation of water within the lake.Data visualisation will be undertaken in conjunction with Dr. Martin Jakobsson (collaborator). The result of the project will be the first fully characterised subglacial lake environment and the establishment of a candidate for future in-situ analysis.
南极冰下湖泊预计将含有独特的微生物生命形式和过去气候变化的详细记录。对这些内容的检查需要进行现场测量,只有在通过地球物理方法充分表征湖泊后才能进行现场测量。在南极洲 101 个已知的冰下湖泊中,没有一个经过测量达到进行有意义的直接采样所需的水平。该提案旨在对南极洲西部(靠近埃尔斯沃斯山脉)一个10公里长的冰下湖进行全面的地球物理勘探。布里斯托大学、英国南极调查局和诺森比亚大学将进行数据分析和建模。冰厚度将通过探冰雷达确定,水深将通过地震勘探找到,冰流量和积冰量将通过直接表面测量获得。将使用一系列数值模型来了解湖泊的历史、湖上冰的流动以及湖内水的循环。数据可视化将与 Martin Jakobsson 博士(合作者)一起进行。该项目的结果将是第一个完全表征冰下湖泊环境的结果,并为未来的原位分析建立了候选方案。
