US-Turkey Cooperative Research: Field Mapping of Quaternary Glaciations in Turkey

0115298Zreda描述：该奖项是为了表彰图森亚利桑那大学水文水资源系的Marek Zreda博士和土耳其安卡拉的Hettepe大学地质工程系的Attila Ciner博士的合作项目。研究人员将进行实地研究，绘制土耳其晚第四纪冰川沉积和古地震海岸线，以量化冰川推进期间的平衡线高度(ELA)凹陷，并收集样本用于宇宙形成年代测定。这项研究的一个主要动机是探索北大西洋和西南亚之间气候变化的较短时间尺度(Henrich和Dansgaard-Oeschger事件)的同步性。因为土耳其位于一个有趣的气候十字路口，它可能会提供有价值的年代学数据。人们对土耳其的冰川历史知之甚少，这项研究可能会导致对欧亚亚热带气候历史的新发现。合作范围：这项合作涉及两位拥有互补专业知识的科学家。Zreda是冰川地貌宇宙成因测年领域的领先者。土耳其研究人员将组织实地考察，提供科学材料(包括航空照片和地图，否则可能无法获取)，并提供土耳其地质知识。美国调查人员将设计和实施样本采集计划，并将在未来的同位素测年中提供技术专业知识。双方将共同进行所有实地调查和测绘。拟议的活动具有极大的潜力，可以促进该领域内和各学科之间的知识进步，并有助于教育课程。

0115298ZredaDescription: This award is for support of a cooperative project by Dr. Marek Zreda, Department of Hydrology and Water Resources, University of Arizona, Tucson and Dr. Attila Ciner, Geological Engineering Department, Hacettepe University, Ankara, Turkey. The investigators will conduct field research to map late quaternary glacial deposits and paleolake shorelines across Turkey in order to quantify equilibrium line altitude (ELA) depression during glacial advances and collect samples for cosmogenic dating. A central motivation for this study is to explore the shorter time scale (Henrich and Dansgaard-Oeschger events) synchrony of climate variation between the North Atlantic and southwest Asian. Because Turkey lies at an interesting climatic crossroads, it may provide valuable chronological data. Little is known about the glacial history of Turkey and this research may lead to new findings on the climatic history of the Eurasian subtropics. Scope: This collaboration involves two scientists with complementary expertise. Zreda is a leader in the field of cosmogenic dating of glacial feature. The Turkish researchers will organize fieldwork, provide access to scientific materials (including aerial photographs and maps that may not otherwise be accessible.), and provide the knowledge of the geology of Turkey. The US investigators will design and conduct sample collections program and will provide the technical expertise in the future isotopic dating. Together the two sides will conduct all field investigations and mapping. The proposed activity has great potential to advance knowledge within the field and across disciplines and contribute to educational curriculum.
