Antarctic Abrasion Target Recovery

这项研究的目的是确定特定地貌过程的速率，以便限制南极洲维多利亚大陆无冰山谷和双峰不同表面记录的事件的年表。具体目标是找回5年前部署的一套样本，这是暴露在南极环境中的长期实验的一部分。这项实验的结果将对该地区冰川历史的研究产生重要影响，因为风蚀目前被视为该地区演变的关键因素之一。这一结果还将对研究隐形石器时代微生物群落及其剩余化石栖息地的演化产生影响，因为磨损被视为一个“速度限制”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.
