Lakes provide valuable sedimentary records for the reconstruction of rapid environmental changes, shifts and crises that have transformed ecosystems in the past. However, precise sediment chronologies are essential for accurately interpreting changes that occur on different timescales (seasonal to multi-millennial) preserved in lake sediment. This session invites studies that use dating techniques such as natural and artificial radionuclides, tephrochonology, varves, OSL, paleomagnetic secular variation and others to establish a detailed lake sediment chronology. We also encourage the presentation of new chronological methods, instrumental developments or numerical advances that allow better or more rigorous age model estimations.
