Termination of Little Ice Age in Northeastern Anatolia, A multi-proxy paleolimnology study of undisturbed sediments, Lake Aygır (Kars, NE Anatolia)

Sedimentary, geochemical and stable isotope analyses of a sediment core (core AY) recovered from Lake Aygır (NE Anatolia) provide evidence the climatic shifts during last ~500 yrs. Sediments in Aygırare composed silty clay with modeled ~0.16 cm/yr sedimentation rate. Multi-proxy downcore distribution detritally-deposited proxy elements, total calcium carbonate, organic carbon isotopes reveal records Industrial Epoch (IE; 18th-19th centuries) termination Little Ice Age (LIA; AD 1350 to 1850), represented by fluctuating Total Organic Carbon (TOC), Ca, Sr relatively low detrital precursors (Fe, Ti, K, Rb, Zr), indicating chemical weathering dry conditions. The upper part (192 cal yrs BP present), identified high input, contains an increasing trend Fe, Zr together δ 18 O 13 C values, warmer conditions IE.
