This project provides funds for a two-year renewal of the St. Elias Erosion-tectonics Project (STEEP). STEEP is a 9 institution, multidisciplinary study of the St. Elias orogen in southern Alaska that involves researchers examining the system from the outcrop to lithosphere scale. To date, STEEP has produced 17 papers with another 9 submitted or nearing submission, sponsored 71 abstracts, will have matriculated 5 masters and 4 Doctoral students by Spring 2010, and fundamentally changed our understanding of Alaskan tectonics and the interaction of tectonics and climate in mountain building. The renewal funds will be used for: 1) final processing and interpretation of some key datasets that were not acquired until year 5 of the project including the marine seismic survey (ship delays) and reoccupation of key GPS sites (weather problems in 2008); and 2) a complete integration of results which was not possible until now due to these delays. A complete integration and synthesis of these superb datasets has the potential to be transformative in our understanding of how crustal structure and tectonic forces interact with Earth surface processes of glacial erosion and sedimentary transport to grow a mountain range and a massive continental shelf.

该项目为圣埃利亚斯侵蚀构造项目 (STEEP) 的两年更新提供资金。 STEEP 是一项针对阿拉斯加南部圣埃利亚斯造山带的 9 个机构的多学科研究，研究人员从露头到岩石圈尺度对该系统进行了检查。 迄今为止，STEEP 已发表 17 篇论文，另有 9 篇已提交或即将提交，赞助了 71 篇摘要，到 2010 年春季将招收 5 名硕士生和 4 名博士生，从根本上改变了我们对阿拉斯加构造以及山区构造与气候相互作用的理解。建筑。 更新资金将用于： 1）对项目第 5 年才获取的一些关键数据集进行最终处理和解释，包括海洋地震调查（船舶延误）和重新占用关键 GPS 站点（2008 年的天气问题）； 2) 由于这些延误，迄今为止无法实现结果的完整整合。这些出色的数据集的完整整合和综合有可能改变我们对地壳结构和构造力如何与冰川侵蚀和沉积物运输的地球表面过程相互作用以形成山脉和巨大大陆架的理解。
