Antarctic Abrasion Target Recovery

本研究的目的是确定 特定的地貌过程，以限制年表 在无冰山谷的各种表面记录的事件， 南极洲维多利亚地的冰原岛峰。 具体目标是 恢复一套5年前部署的样本， 长期暴露于南极环境的实验。 这个实验的结果将具有重要的意义 研究该地区的冰川历史， 目前被认为是进化的关键因素之一， 该地区 这些结果也将对以下研究产生影响： 隐石内微生物群落的演化及其 残留的化石栖息地，因为磨损被视为“速率”， 限制”因素。

The objective of this research is to determine the rates of specific geomorphic processes in order to constrain the chronology of events recorded by various surfaces in the ice-free valleys and nunataks of Victoria Land, Antarctica. The specific objective is to recover a suite of samples deployed 5-years ago as part of a long-term experiment of exposure to the Antarctic environment. The results of this experiment will have important implications for research into the glacial history of the area, as wind erosion is presently seen as one of the key factors in the evolution of the area. The results will also have implications for studies of the evolution of cryptoendolithic microbial communities and their remnant fossilized habitats, as abrasion is seen as a "rate limiting" factor.
