      abstract     = {Lago del Desierto (49 degrees 02'S, 72 degrees 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 records from this region are generally
                      short and scarce, environmental archives are the only source
                      of long-term records of climate variations. In this study,
                      the potential of laminated proglacial sediments from Lago
                      del Desierto as a palaeoclimate archive is evaluated. Two
                      parallel gravity cores (max. length 283 cm) were analysed
                      using a multi-proxy approach. Radiometric dating (C-14,
                      Pb-210 and Cs-137) and tephrochronology document that the
                      sediment cover the last 2000 years. Especially in the middle
                      part of the record, numerous turbidites make climate
                      variations difficult to decipher. However, after exclusion
                      of event layers changes in sedimentological, mineralogical,
                      and geochemical parameters reveal a long-term trend of
                      runoff variations and sediment accessibility controlled by
                      changes in temperature and precipitation. An abrupt
                      transition in sediment composition occurred around AD 850
                      and is interpreted as a change in sediment availability
                      related to the initial exposure of formerly glaciated areas
                      in the catchment. This striking change mirrors the onset of
                      warmer climate conditions during the Medieval Climate
                      Anomaly. Moreover, the Little Ice Age cooling and the
                      subsequent 20th century warming can be traced in the
                      sediment record corresponding to an overall trend observed
                      for southern South America. The proglacial lacustrine
                      sediment record of Lago del Desierto thus constitutes a link
                      between glacier studies of the HPS and other terrestrial
                      climate archives in a region were long, and continuous
                      climate records are still rare. (C) 2010 Elsevier B.V. All
