Linkage of climate and geodynamics in development of plateaux at collisional plate margins: marine contributions to an international study of the Central Anatolian Plateau.

人类必须更好地了解地球系统，以便决策者能够制定适当的长期社会和经济战略，处理各种环境问题，包括全球变化。这是一个跨学科项目，研究气候和固体地球动力学之间的联系，在山区高原的演变。这些是由板块碰撞的构造驱动的，但当地气候通过侵蚀，运输和沉积来改变上升的表面。 反过来，不断变化的山脉带可能会影响全球气候。 造山高原是山区地带内的高平原，它导致当地气候变化（如雨影），并受其影响。年轻的造山高原保存了其演化的岩石记录，为我们提供了一个特殊的机会，以提高我们对地表和深部过程之间的重要联系的理解，并模拟它们。 土耳其南部的中安纳托利亚高原位于非洲板块和安纳托利亚板块交汇处的活动会聚板块边缘之上。 大陆碰撞才刚刚开始，我们假设碰撞是造成高原隆升的原因。 这一新项目涉及对高原隆起的陆上研究，并辅之以对邻近近海盆地相应沉降的研究，同时进行地震勘测以确定活动板块边缘的地壳结构，以及综合所有信息的地球动力学建模，加拿大小组将在这一研究的海洋部分发挥关键作用：2008年5月，对东地中海的一个主要的当地沉积汇-格克苏三角洲进行了高分辨率地震反射勘测;以及计划于2009年8月进行的从非洲板块到安纳托利亚板块中部安纳托利亚高原的广角地壳地震勘测。 我们为调查（已由我们的合作伙伴安排）和后续数据处理、建模和解释寻求资金。我们要求NSERC提供的捐款将从我们的欧洲合作伙伴那里获得超过6倍的资金。

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.
