"Late glacial and Holocene palaeohydrology in the western Mediterranean region: the Lake Estanya record (NE Spain)"

Click here to view linked References The multi-proxy analysis of sediment cores recovered in karstic Lake Estanya (42°02 ' N, 0°32 ' E; 670 m a. s. l., NE Spain), located in the transitional area between the humid Pyrenees and the semi-arid Central Ebro Basin, provides the first high-resolution, continuous sedimentary record in the region, extending back the last 21 000 years. The integration of sedimentary facies, elemental and isotopical geochemistry and biogenic silica, together with a robust age model based on 17 AMS radiocarbon dates, enables precise reconstruction of the main hydrological and environmental changes in the region during the last deglaciation. Arid conditions, represented by shallow lake levels, predominantly saline waters and reduced organic productivity occurred throughout the Last Glacial Maximum (21 – 18 cal kyrs BP) and the late glacial, reaching their maximum intensity during the period 18- 14.5 cal kyrs BP (including Heinrich event 1) and the Younger Dryas (12.9 – 11.6 cal kyrs BP). Less saline conditions characterized the 14.5- 12.6 cal kyrs BP period
