Palaeoclimate variability must be constrained to predict the nature and impacts of future climate change in the Eastern Mediterranean. Here, we present a late Holocene high-resolution multiproxy dataset from Kocain Cave, the first of its kind from SW Turkey. Regional fluctuations in effective-moisture are recorded by variations in magnesium, strontium, phosphorous and carbon isotopes, with oxygen isotopes reacting to changes in precipitation and effective-moisture. The new record shows a double-peak of arid conditions at 1150 and 800 BCE, a wet period 330-460 CE followed by a rapid shift to dry conditions 460-830 CE, and a dry/wet Medieval Climate Anomaly/Little Ice Age pattern. Large discrepancies exist between Turkish records and the Kocain record, which shares more similarities with other Eastern Mediterranean coastal records. Heterogeneity of regional climate and palaeoclimate proxy records are emphasised.
