Paleohydrological changes in the Eastern Mediterranean region during the early to mid-Holocene recorded in plant wax n-alkane distributions and δ13CTOC – New data from Tenaghi Philippon, NE Greece

•Multiproxy study of early Holocene of Tenaghi Philippon, focusing on 8.2kyrBP event.•n-Alkane distributions and δ13CTOC reflected changes in peat surface moisture.•Relatively low surface moisture characterized interval before 8.2kyrBP event.•Increase in surface moisture coeval with change in atmospheric circulation and precipitation during event.•Changes in surface moisture after event likely linked to increased activity of the karstic system.
