The proposed research is in two subjects: The first is understanding the processes responsible for earthquakes and mountain building in western Canada and elsewhere. The second is the occurrence and process of formation of natural marine gas hydrate, especially off western Canada. (1) In the past 10 years, very high precision GPS measurements have resulted in a revolution in our ability to detect and understand the short-term crustal strain buildup and release associated with earthquakes and the long-term deformation of mountain building. The deformation responsible for earthquakes in western Canada will be mapped through repeated campaign and continuous very high precision GPS measurements in SW British Columbia, the Queen Charlotte area, and in the Yukon. The study will include determining the forces that drive the deformation and the variations in the strength in the earth that respond to the deforming forces. (2) Marine gas hydrates are a frozen form of natural gas that occurs beneath the continental slope in some marine areas such as off Vancouver Island and in the arctic. It may provide a new source of clean energy, may play a role in climate change, and may be a hazard in conventional oil and gas exploration in deep water and in the arctic. The study will include marine surveys, and the analyses of data from the recently completed IODP drilling of hydrate off Vancouver Island.

拟议的研究分为两个主题：第一个是了解加拿大西部和其他地方地震和造山的过程。 二是海洋天然气水合物的产状和形成过程，特别是加拿大西部海域。 (1)在过去10年中，非常高精度的全球定位系统测量使我们探测和了解与地震有关的短期地壳应变积累和释放以及造山运动的长期变形的能力发生了革命性变化。 将通过在西南部不列颠哥伦比亚省、夏洛特女王地区和育空地区进行反复活动和连续的高精度GPS测量，绘制加拿大西部地震的变形图。 这项研究将包括确定驱动变形的力以及地球对变形力作出反应的强度变化。 (2)海洋天然气水合物是天然气的一种冻结形式，存在于温哥华岛和北极等海洋区域的大陆坡下。 它可能提供一种新的清洁能源，可能在气候变化中发挥作用，并可能对深水和北极地区的常规石油和天然气勘探造成危害。 这项研究将包括海洋调查，以及对最近完成的温哥华岛附近水合物IODP钻探数据的分析。
