Landscape evolution in the Arctic

拟议中的研究利用了地球科学中的两项新技术：一种改进的方法，用于确定深埋岩石（几公里）被挖掘出来和现在出现在地球表面的速度；还有一种测定地表暴露在宇宙辐射中时间的新方法。总之，这些新技术将被用来为北极长期存在的问题提供答案。这些问题包括：为什么沿着从魁北克和拉布拉多北部的托恩加特山脉，沿着巴芬岛和德文岛东北部延伸到埃尔斯米尔岛的山脉会有这么高的山脉和深谷？其他研究解决了与不同时期北极景观侵蚀历史有关的问题。这项研究有助于降低矿产和石油勘探的风险，因为它有助于绘制北极地区具有经济潜力的岩石，为改善石油工业中使用的盆地和热模型提供所需的信息，并帮助改进在冰川可能侵蚀或可能不侵蚀含矿岩石的地区进行矿产勘探的方式。

The proposed research makes use of two new technologies in geosciences: an improved method for determining the history of how rapidly a deeply buried rock (several km) was exhumed and is now at the Earth's surface; and a new method for dating how long a surface has been exposed to cosmic radiation. Together, these new technologies will be employed to provide answers to long-standing questions in the Arctic. These questions include: Why is there such high mountains and deep valleys along a mountain range that extends from the Torngat Mountains in northern Quebec and Labrador, along northeastern Baffin Island and Devon Island, to Ellesmere Island. Other research addresses questions related to the history of erosion of Arctic landscapes over different time periods. The research is useful to reduce risk in mineral and petroleum exploration by contributing to mapping rocks of economic potential in the Arctic, providing information needed to improve basin and thermal models employed in the petroleum industry, and helping refine the way the mineral exploration is done in areas where glaciers may or may not erode the ore bearing rocks.
