Lake Van (eastern Anatolia in Turkey) is the fourth largest of all terminal lakes in the world (surface area of 3,522 km², volume of 576 km³, maximum depth of 450 m, max. diameter 130 km WSW-ENE). Caused by the quality of the sediments (annually laminated) and the location in a climatic sensitive region, it is an excellent target for ICDP deep drilling. Following the successful realization of a pre-site survey in 2004 including a seismic cruise and coring campaign for a set of new cores, the main goal of the present proposal is the continuation of multidisciplinary scientific work on short cores (5 m ¿ 10 m sediment depth) including magnetic susceptibility, physical properties, stable isotopes, pollen and spores, and absolute datings. We submitted a proposal requesting ICDP support to hold an international workshop in preparation of the Lake Van Drilling Project. Based on the recommendation of the ICDP Science Advisory Group the Executive Committee is generally willing to allocate financial support for the proposed workshop. The prolongation of our DFG project is needed to produce substancial results both for the ICDP workshop in 2006 and for the final ICDP Drilling Proposal, which will be submitted probably in January 2007.

凡湖（土耳其安纳托利亚东部）是世界上所有终端湖泊中的第四大湖泊(表面积3522平方公里，体积576平方公里，最大深度450米。直径130公里)。由于沉积物的质量（每年分层）和气候敏感地区的位置，它是ICDP深钻的绝佳目标。继2004年成功实现现场前调查，包括地震巡天和一组新岩心的取芯活动之后，本提案的主要目标是继续对短岩心（5米至10米沉积物深度）进行多学科科学研究，包括磁化率、物理性质、稳定同位素、花粉和孢子以及绝对年代测定。我们提交了一份提案，要求ICDP支持举办一次国际研讨会，为Lake Van钻井项目做准备。根据ICDP科学咨询小组的建议，执行委员会一般愿意为提议的研讨会分配财政支持。我们需要延长DFG项目，以便为2006年的ICDP研讨会和最终的ICDP钻井提案（可能于2007年1月提交）产生实质性成果。
