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).

凡湖(土耳其安纳托利亚东部)的面积为3,522千米，体积为576千米，最大深度为450米。它向西南偏东方向延伸130千米，是世界第四大终端湖。此前的科学研究表明，凡湖中存在每年一次的层状沉积物。然而，由于现有钻探设备的限制，覆盖冰晚期和全新世(最后15,000年)的沉积物深度只能达到10米以下。重要的是要获取更古老的沉积物，至少是来自上一次间冰期-冰期周期，包括伊米亚间冰期，甚至更早的周期。由于凡湖问题的影响，只有把国家和国际的经验和专门知识集中在人发会议的框架下，才有可能取得进一步的进展。在2001年欧洲湖泊钻探项目最后一次会议上，有人建议首先提出一项开发大型湖泊钻探项目的提案，该项目的设备池为GLAD800。在这方面，应借鉴喀喀湖和马拉维湖钻探项目的经验。申请者被要求促进和协调前期调查的第一步，并获得国家资金(第一年的旅费)。
