Lake Van on the high plateau of eastern Anatolia in Turkey has a surface area of 3,520 km2, a volume of 575 km3, a maximum depth of 450 m, and extends for 130 km WSW-ENE. It is the fourth largest terminal lake in the world. Within the sensitive climate region of eastern Anatolia, it represents a first order continental climate archive between the Black Sea, the Arabian Sea and the Red Sea. Based on an ICDP deep drilling operation (coordinated by the applicant), two sites with multiple holes were drilled in summer 2010. The ‘Ahlat Ridge’-Site, the most important site for palaeoclimatological studies, was drilled on a low ridge in the deep basin (water depth ~360 m) where a complete 220 m thick sedimentary section was recovered. It holds a continuous climate archive encompassing ca 500,000 years partly based on annually laminated sediments. In this project proposal, particular attention is paid to the identification and interpretation of vegetation and climate oscillations during the last glacialinterglacial cycles by using pollen and isotope data. We will determine if pollen variations are correlated temporally with orbital forcing and Dansgaard-Oeschger cycles. Through such an approach we will evaluate the timing, direction, and magnitude of continental environmental changes and compare them with marine and ice-core records.

土耳其东部安纳托利亚高原上的凡湖面积为3520平方公里，体积为575平方公里，最大深度为450米，向西南偏东方向延伸130公里。它是世界第四大终点湖。在东安纳托利亚气候敏感地区，它代表了黑海、阿拉伯海和红海之间的一级大陆性气候档案。根据ICDP的一项深井钻探作业(由申请人协调)，2010年夏天钻了两个多孔场地。“Ahlat Ridge”遗址是古气候学研究中最重要的遗址，是在深盆低脊(水深~360m)上钻探的，在那里发现了完整的220m厚的沉积剖面。它保存着大约50万年的连续气候档案，部分是基于每年的层状沉积物。在本项目提案中，特别注意利用花粉和同位素数据识别和解释上一次冰川-间冰期周期期间的植被和气候振荡。我们将确定花粉变异是否与轨道强迫和丹斯加德-奥施格旋回在时间上相关。通过这种方法，我们将评估大陆环境变化的时间、方向和大小，并将它们与海洋和冰芯记录进行比较。
