We present the multi-proxy records of centennial scale climate and environmental changes over the last 3.5 ka from a varved sediment core in Lake Van, eastern Turkey. The multi-proxy analyses include ostracod counts, mu-XRF elemental, total organic (TOC) and inorganic carbon, C-N elemental and stable isotopes. For the age model of the core, we use radionuclide (Pb-210 and Cs-137) analysis and varve counting. Large differences between Accelerator Mass Spectrometry (AMS) radiocarbon dates from TOC and varve ages indicate reservoir ages of 1.2-3.8 ka calBP. Average sedimentation rate for the last 170 years (top 75mm of the core) ranges between 0.42 and 0.54 mm/yr according to Pb-210 dating.
