A Record of Holocene Climate Change from Lake Geochemical Analyses in Southeastern Arabia
Abstract Lacustrine sediments from southeastern Arabia reveal variations in lake level corresponding to changes in the strength and duration of Indian Ocean Monsoon (IOM) summer rainfall and winter cyclonic rainfall. The late glacial/Holocene transition of the region was characterised by the develop...
