It is important that humankind better understand the Earth system, so that policy makers can develop suitable, long-term social and economic strategies to deal with various environmental issues, including global change. This is an interdisciplinary project to study the linkages between climate and solid Earth dynamics, in the evolution of plateaux in mountain belts. These are driven by the tectonics of colliding plates, but local climate modifies the rising surface through erosion, transport and deposition.  In turn, the evolving mountain belt may affect global climate.  Orogenic plateaux are high plains within mountain belts, which result in, and are modified by, local climatic variations (rain-shadows, for instance). Young orogenic plateaux, which preserve a rock record of their evolution, offer a special opportunity to enhance our understanding of the essential linkage between surface and deeper processes, and model them.  The Central Anatolian Plateau, in southern Turkey, lies above an active convergent plate margin, where the African and Anatolian plates meet.  Continental collision is just starting, and we hypothesize that the collision is responsible for the uplift of the Plateau.  This new project involves onland studies of the Plateau uplift, complemented by studies of corresponding subsidence in adjacent offshore basins, together with seismic surveys to determine crustal structure of the active plate margin, and geodynamic modeling integrating all the information.The Canadian team will play a pivotal role in the marine component of this research: a high-resolution seismic reflection survey of the Göksu delta, a major local sediment sink, in the eastern Mediterranean, in May 2008; and a wide-angle crustal seismic survey from the African plate to the Central Anatolian Plateau on the Anatolian plate, planned for August 2009.  We seek funding for the surveys (already scheduled by our partners) and the follow-up data processing, modelling and interpretation. Our requested contribution from NSERC will leverage over 6 times as much funding from our European partners.

重要的是，人类更好地了解地球系统，以便决策者可以制定合适的，长期的社会和经济战略来处理包括全球变化在内的各种环境问题。这是一个跨学科的项目，旨在研究山地皮带中高原的演变气候与固体地球动力学之间的联系。这些是由碰撞板的构造驱动的，但是局部气候通过侵蚀，运输和沉积来修饰上升的表面。反过来，不断发展的山带可能会影响全球气候。造山高原是山带内的高板，导致并通过局部气候变化（例如，雨水造物）进行了修改。保持其进化的岩石记录的年轻造山高原为我们提供了一个特殊的机会，可以增强我们对表面和更深过程之间基本联系的理解，并建模它们。土耳其南部的中央安纳托利亚高原位于非洲和安纳托利亚板相遇的积极收敛板缘上方。大陆碰撞才刚刚开始，我们假设碰撞是造成高原的提升的原因。 This new project involves onland studies of the Plateau uplift, completed by studies of corresponding subsidence in adjacent offshore basses, together with seismic surveys to determine crustal structure of the active plate margin, and geodynamic modeling integrating all the information.The Canadian team will play a pivotal role in the marine component of this research: a high-resolution seismic reflection survey of the Göksu delta, a major local 2008年5月，在地中海东部的沉积物汇；以及计划于2009年8月举行的Anatolian板上的非洲板到中部安纳托利亚高原的广角地震调查。我们寻求调查（已经由我们的合作伙伴计划）和后续数据处理，建模和解释的资金。我们要求的NSERC捐款将利用欧洲合作伙伴的6倍以上的6倍。
