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企业涉及项目（陡峭）的两年续期提供资金。 陡峭的是对阿拉斯加南部圣埃利亚斯造基因的9个机构，多学科研究，涉及研究人员检查从露头到岩石圈量表的系统。 迄今为止，陡峭的作品已经制作了17篇论文，另有9篇提交或临近提交的论文，赞助了71个摘要，将在2010年春季登记5名硕士和4位博士生，从根本上改变了我们对阿拉斯加构造学以及山间建筑中构造和气候的相互作用的理解。 续签资金将用于：1）直到项目的第5年才能获得的一些关键数据集的最终处理和解释，包括海洋地震调查（船舶延迟）和重新集中关键GPS网站（2008年的天气问题）； 2）由于这些延迟，到目前为止无法进行完整的结果整合。这些超级数据集的完整整合和合成有可能在我们理解地壳结构和构造力与冰川侵蚀和沉积运输的地面过程中如何相互作用，从而发展山脉和巨大的大陆架。
