A robust age-model was established from 13 radiocarbon ages, and indicates that the base of the sequence was deposited at ca. 12 500 cal yr BP, when the lake-level was low. Variations in sedimentological (TOC, CaCO3, TC, N, S, grain-size, XRF, \u03b418Ocarb, \u03b413Ccarb, \u03b413Corg) data were linked to hydro-acoustic data and indicate that warmer and more humid climate conditions characterized the remaining period of the Younger Dryas until the beginning of the Holocene. The Holocene exhibits significant environmental variations, including the 8.2 ka and 4.2 ka cooling events, the Medieval Warm Period, and the Little Ice Age. Human induced erosion processes in the catchment of Lake Dojran intensified after 2800 cal yr BP.","type":"researchdata_literature","resources":[{"description":"","format":"URL","url":"http://www.clim-past-discuss.net/8/5743/2012/cpd-8-5743-2012.html","created":"2017-10-06T19:36:20.920649","state":"active","package_id":"d9c4e3f8-dff1-41b9-b5a2-7cbd34758a5f","last_modified":"2021-10-23T07:10:54","id":"7f3f9f9c-7e25-4a14-9ce4-8dbdf08b46e6","name":"Climate of the Past"}],"tags":[{"name":"GQT2"},{"name":"GQT3"},{"name":"LRQ13"},{"name":"LRQ7"}],"extras":[{"key":"bibtex:address","value":""},{"key":"bibtex:author","value":"Francke, A and Wagner, B and Leng, M and Rethemeyer, J"},{"key":"bibtex:booktitle","value":""},{"key":"bibtex:citation","value":"Francke, A., Wagner, B., Leng, M.
