With the applied multi-proxy approach rapid climatic changes before the turn of the first millennium were detected followed by medieval droughts which are intersected by moist and/or cold periods of varying durations and intensities. The 'total inorganic carbon' content was identified as a sensitive lake level indicator. This proxy suggests that during the late Middle Ages (ca. AD 1230-1410) the lake level was rather low representing a signal of the 'Medieval Climate Anomaly' in southeastern Patagonia. At the beginning of the 'Little Ice Age' the lake level rose considerably staying on a high level during the whole period. Subsequently, the lake level lowered again in the course of the 20th century. STUDY NOTES: Physical properties and geochemistry data of Laguna Potrok Aike (southern Patagonia) are given on depth scale and on time scale (calibrated radiocarbon years). This data set, based on a 1m gravity core, includes the last ca. 1600 years.
