COLLABORATIVE RESEARCH: St. Elias Erosion and Tectonics Project (STEEP)

该项目为圣埃利亚斯侵蚀构造项目（陡）的两年续期提供资金。陡坡地质研究所是一个对阿拉斯加南部圣埃利亚斯造山带进行多学科研究的机构，研究人员从露头到岩石圈范围检查该系统。迄今为止，该中心已经发表了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名硕士和4名博士研究生，并从根本上改变了我们对阿拉斯加构造和构造与气候在造山过程中的相互作用的认识。续期资金将用于：1)最后处理和解释一些直到项目第5年才获得的关键数据集，包括海洋地震调查（船舶延误）和重新占用关键GPS站点（2008年天气问题）；2)由于这些延迟，直到现在还不可能完全整合结果。这些极好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地球表面冰川侵蚀和沉积运输过程相互作用以形成山脉和巨大大陆架的理解。

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.
