We studied the internal lake processes that control the spatial distribution and characteristics of modern sediments at the ICDP (International Continental Scientific Drilling Program) deep drilling site in Laguna Potrok Aike, southern Patagonia, Argentina. Sediment distribution patterns were investigated using a dense grid of 63 gravity cores take...

Lago del Desierto (49°02′S, 72°51′W) is situated in the climatically sensitive area of Southern Patagonia close to the Hielo Patagonico Sur (HPS or South Patagonian Ice Field, Argentina). Next to marine records and Antarctic ice cores, this continental area is important to reveal hemispheric and global climate trends. As instrumental climate record...

The maar Laguna Potrok Aike (51°S, 70°W) is situated in the dry steppe environment of southern Patagonia. This 100 m deep lake is a palaeolimnological key site among the emerging terrestrial climate archives of the southern hemisphere and therefore was chosen as an ICDP drilling site. Interdisciplinary multi-proxy sediment studies document the sens...

Paleoenvironmental records extending well into the last glacial period are scarce in the steppe regions of southern South America. Here, we present a continuous record for the past 55 ka from the maar lake Laguna Potrok Aike (51°58′ S, 70°23′ W, southern Patagonia, Argentina). Previous studies on a sedimentary core from a lake level terrace near th...
