Özet

Magnetic susceptibility, geochemistry, mineralogy and palynology of sediments from Lake Iznik in Northwestern Anatolia, Turkey, provide a 4700 year record of climatic trends and events. The measured proxies allow a reconstruction of variations in humid/dry periods and lake level changes. The Lake Iznik sedimentary sequence points to an oscillating trend of humid periods interrupted by rapid climate change (RCC) to arid periods. Especially abrupt lithologic and geochemical changes at 4.2 and 3.3 ka calBP may outline intense droughts, which extremely lowered the lake level. For the last 2000 years, the effects of the Roman warm period, Dark Age cold period, Medieval Warm Period and Little Ice Age are recorded within Lake Iznik sediments. Besides many similarities of local climatic periods with other records from the Eastern Mediterranean, there are also differences indicating the complex pattern of the climate in the region.

We are much indebted to the students Sebastian Bernhardt, Yvonne Cherubini, Derya Gürer, and Miriam Sass for their help during the laboratory work. We like to thank Dr. R. Hoffbauer for XRF analyses on discrete samples as well as Dr. H. Wörmann, B. Schulte-Van-Berkum, S. Berkau for gamma spectrometry, XRD analyses and technical support in the laboratory (Steinmann Institute, University of Bonn), and T. Kiefer and A. Glogau (Plant Nutrition Institute, University of Bonn) for CNS and TOC analyses. The Alfred Wegener Institute (Bremerhaven) is acknowledged for providing a gravity corer for field campaigns and XRF core scanner, MSCL and radiography for laboratory analysis. For 14 C results, we are grateful to Liviu Goisan (Woods Hole Oceanographic Institution). We thank the reviewers (Mustafa Karabıyıkoğlu and two anonymous referees) and editors for their constructive comments and editorial efforts that improved the paper significantly. Authors would also like to thank to Dr. Sena Akçer Ön and Dr. M. Ersen Aksoy for fruitful discussion on the manuscript. Special thanks are due to the Turkish army police and Agricultural District Office (Tarım İlçe Müdürlüğü, İznik), namely Ali Okkali for supporting us with their boats. This research was funded by the German Research Foundation (DFG), grant numbers FR 1199/1 & 2 and B4 of the CRC 806 , and the ITU Scientific project Office (BAP), grant number 11_04_277 . The German Academic Exchange Service (DAAD) kindly provided a PhD grant for a research stay of Umut B. Ülgen at the Steinmann Institute of the University of Bonn (grant no. A/04/17884 , ref: 322).
