Short summary
This article deals with an investigation on the seasonal change in the sources of Saharan dust deposited in and off Mauritania using mineralogy. Onshore, dust was sourced from Western Sahara and a local source during summer and from Mauritania and Mali during winter. Offshore, dust was sourced from Mauritania, Mali and Libya during summer and from Western Sahara during winter. The outcome of the study has important implications for the reconstruction of past climates using dust deposits.
