Lake Van, Turkey - Pre-Site Survey for a potential new ICDP site

凡湖（土耳其安纳托利亚东部）的表面积为3522平方公里，体积为576平方公里，最大深度为450米。它全长130公里，是世界上第四大终端湖泊。以前的科学研究表明，凡湖每年都有层状沉积物。然而，由于现有钻井设备的限制，只能到达覆盖晚冰期和全新世（过去15000年）的沉积物深度小于10米。获得更古老的沉积物是很重要的，至少是从最后一个间冰期-冰期旋回，包括埃米间冰期，甚至更古老的旋回。由于凡湖的规模，只有将国家和国际经验和专门知识集中在国际发展与发展论坛的框架下，才能取得进一步进展。在2001年欧洲湖泊钻井项目（ELDP）的最后一次会议上，有人建议开始使用ICDP设备池GLAD800开发大型湖泊钻井。在这方面，应该利用的的喀喀湖和马拉维湖钻井项目的经验。申请人被要求促进和协调现场前调查的第一步，并获得国家资金（第一年的旅费）。

Lake Van (eastern Anatolia in Turkey) has a surface area of 3,522 km², a volume of 576 km³ and a maximum depth of 450 m. It measures 130 km WSW-ENE and is the fourth largest of all terminal lakes in the world. Previous scientific work has shown that annually laminated sediments exist in Lake Van. However, caused by the limitation in drilling equipment available it was only possible to reach a sediment depth less than 10 m covering the Late Glacial and Holocene (last 15,000 years). It would be important to obtain older sediments, at least from the last interglacial-glacial cycle including the Eemian interglacial, or even older cycles. Caused by the dimension of Lake Van, it is only possible to make further progress by focussing national and international experience and expertise under the umbrella of ICDP. During the final European Lake Drilling Project (ELDP) meeting 2001 it was suggested to start with a proposal development for large lake drilling with the ICDP equipment pool GLAD800. In this respect the experience of the drilling projects of lakes Titicaca and Malavi should be used. The applicant was asked to promote and to co-ordinate the first steps of the pre-site survey and to acquire national funds (travel expenses for the first year).
