Collaborative Study: Re-evaluation of the Late Paleozoic Gondwanan Ice Age in Northern Victoria Land (Antarctica) and Tasmania (Australia)

摘要该奖项支持对古生代晚期冈瓦纳冰期沉积物的初步研究。这些沉积物代表了地球从冰窖到温室世界的最后一次转变。该项目将从塔斯马尼亚（澳大利亚）的冰近端沉积物中获得新的地层学、沉积学和地球化学数据。其结果将是一个强大的、区域尺度的年代地层框架，可以纳入全球视野。如果成功，这项研究将为在南极洲维多利亚地北部开展类似沉积物的工作铺平道路。这项工作的结果将有助于建立过去气候的模型。就更广泛的影响而言，社会将受益于对冰库气候模式期间气候变率和幅度的了解，包括从冰库气候状态向温室气候状态过渡期间的变化，这可能适用于不久的将来当前地球自身的气候。

AbstractThis award supports a pilot study of deposits from the late Paleozoic Gondwanan ice age. These deposits represent the last time that the earth transitioned from an ice-house to greenhouse world. This project will generate new stratigraphic, sedimentologic, and geochemical data from ice-proximal deposits in Tasmania (Australia). The outcome will be a robust, chronostratigraphic framework of regional scale that can be incorporated into global views. If successful, this study will pave the way work on similar deposits in northern Victoria Land, Antarctica. The results from this work will contribute to models of past climates. In terms of broader impacts, society will benefit from insights gained on rates and magnitudes of climate variability during icehouse climate modes, including changes during the transition from icehouse to greenhouse climate states, which may apply to the current earth's own climate in the near future.
