      abstract     = {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 taken
                      throughout the lake basin and 40 additional shoreline
                      samples. Analysis of the surficial sediment distribution
                      points to distinct internal depositional dynamics induced by
                      wind-driven lake internal currents. Distribution maps
                      illustrate that the spatial characteristics of analysed
                      variables are linked to high erosional wave activity.
                      Persistent wave action and littoral erosion along all
                      shores, especially the eastern shore, is caused by
                      prevailing Southern Hemispheric Westerlies. Several sediment
                      variables (grain size, benthic diatoms, total inorganic
                      carbon and calcium) indicate re-suspension of littoral
                      sediment followed by re-distribution to profundal
                      accumulation areas near the eastern shore. Variations within
                      the catchment influence sediment characteristics in the
                      north-eastern bay. That area is characterized by different
                      mineralogical and sedimentological conditions as well as
                      greater accumulation of pollen, inorganic carbon and
                      diatoms. These findings are related to the influence of
                      episodic inflow into this bay. Spatial differences in stable
                      isotope values throughout the lake suggest that ephemeral
                      tributaries around the lake basin may also contribute to the
                      detected spatial sediment variations.},
