Holocene playas as sedimentary evidence for recent climate change in the presently hyperarid western desert, Egypt
… An optical date of 15,120 cal yr on basal aeolian sediments indicates that the deflation basin was mantled with aeolian sands during the Late Pleistocene. Overlying Holocene fluvio-lacustrine muds and gravels attests to the former availability of ponded runoff waters at this now-hyperarid …

The development and evolution of Etosha Pan, Namibia
… the rest of the basin, then denied of lacustrine activity, were intermittently riddled with a veneer of sediment, especially during phases of intensified aeolian activity. In the mean time, the area that was regularly receiving fluvial input started to shape up as a distinct lake with the …

Stormy records from peat bogs in south-west Sweden : implications for regional climatic variability and vegetation changes during the past 6500 years
… to reconstruct and explain variations in storm activity, humidity, vegetation composition and land cover in south-west Sweden during the past 6500 years. Two ombrotrophic bogs, Store Mosse and Undarsmosse, situated on the coastal plain of Halland, were selected for this purpose. The coastal …
