The long-term vision of the proposed research program is to understand the mechanisms that shape landscapes and advance knowledge of the interaction between processes in the earth and the atmosphere. Toward the achievement of this vision a set of research objectives are formulated and specific projects are designed that all center in the Northern Canadian Cordillera (NCC). The quantification of timing and spatial distribution of Cordilleran topography is relevant for our understanding of the evolution of climate patterns that affect the entirety of Canada. The NCC is an excellent natural laboratory to investigate these interacting tectonic-climate-landscape processes because of: 1) the long history of plate tectonic activities that resulted in the continental growth of western Canada, 2) the high northern latitude where climate variations have a stronger effect on surface processes by glacial erosion, and 3) the present-day seismicity that shows tectonic forces are transferred far into the continent. The short-term objectives of the research program aim to use a variety of dating and modeling techniques to identify the spatial variations of rock thermal histories across major geologic structures and tectonic units that are located between the Pacific Ocean and the Canadian Shield. The data will be integrated with other datasets on crustal deformation provided by geologic and geophysical observations and geomorphic analysis. The data acquired through the proposed activities will build the foundation for a deformation- and landscape-evolution model, which will ensure to achieve the long-term objective of the program. The scientific approach of the research program is designed to provide excellent opportunities for HQP training in a multi-disciplinary and diverse research environment that will include collaborations among research groups at the University of Calgary, scientists from government agencies and industry, and international collaborators. HQP training will include various field-, laboratory- and modeling skills, the responsible conduct of scientific research, and effective dissemination of research results. The expected significance of the proposed program lies in the improved understanding of the geologic processes that resulted in the current distribution of ore and mineral deposits, conventional and geothermal energy resources, and zones of seismic hazards in western Canada. The landscape evolution model will provide important boundary constrains for climate models of North America.

拟议的研究计划的长期视觉是了解塑造景观的机制，并提高地球过程与大气之间的相互作用的知识。为了实现这一愿景，制定了一组研究目标，并设计了特定的项目，所有这些都集中在加拿大北部山脉（NCC）。定时和空间分布的脐带地形图与我们理解影响整个加拿大气候的气候模式的演变有关。 NCC是一个出色的自然实验室，可以研究这些相互作用的构造气候 - 气候 - 景观过程，因为：1）板块构造活动的悠久历史，导致加拿大西部的大陆生长，2）高北纬度的高北纬度，气候变化对冰川侵蚀对表面过程的影响更强，而冰川衰落则表明了当今的斜视势力是转变的。该研究计划的短期目标旨在使用各种约会和建模技术来确定位于太平洋和加拿大盾牌之间的主要地质结构和构造单元之间岩石热历史的空间变化。该数据将与其他数据集集成有关地质和地球物理观察和地球物质分析提供的地壳变形的数据集。通过拟议活动获得的数据将为变形和景观进化模型奠定基础，这将确保实现该计划的长期目标。该研究计划的科学方法旨在为HQP培训提供多种学科和多样化的研究环境中的绝佳机会，其中包括卡尔加里大学的研究小组之间的合作，政府机构和工业的科学家以及国际合作者。 HQP培训将包括各种现场，实验室和建模技能，负责任的科学研究以及有效传播研究结果。拟议计划的预期意义在于对加拿大西部西部地震危险的当前分布，常规和地热能资源以及地震危害的地区以及地震危害区域的当前分布，对地质过程的预期意义。景观演化模型将为北美气候模型提供重要的边界约束。
