Lake van, Turkey - a potential new ICDP site: Paleoecological investigations based on lacustrine sediments (short cores from coring campaign 2004)

凡湖(土耳其东部的安纳托利亚)是世界上第四大终端湖(面积3,522平方公里，体积576千米，最大深度450米)。直径130公里，西南偏西-ENE)。由于沉积物的质量(每年分层)和位于气候敏感地区的位置，它是ICDP深部钻探的极好目标。在2004年成功地进行了现场前期调查，包括一系列新岩心的地震巡航和取心活动之后，本提议的主要目标是继续开展关于短岩心(5米至10米沉积深度)的多学科科学工作，包括磁化率、物理性质、稳定同位素、花粉和孢子以及绝对测年。我们提交了一份提案，请求ICDP支持举办一次国际研讨会，以筹备凡湖钻井项目。根据国际地球科学中心科学咨询小组的建议，执行委员会总体上愿意为拟议的讲习班提供财政支助。我们的DFG项目需要延长，以便为2006年的ICDP研讨会和可能将于2007年1月提交的ICDP钻探最后提案产生实质性成果。

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.
