Abstract

Fundamental to advancing contemporary understandings of desert landscape dynamics is the need to address the lack of quantification of surface processes (Mayaud et al., 2017). This project seeks to address this issue by combining a range of innovative research techniques and analytical methods. The celerity of dunes within Saharan sand seas will be quantified with the application of COSI-Corr (Ayoub et al., 2009) to Landsat imagery for the years 1985, 1995, and 2005. The scale of this application will be unique in the scientific literature and will identify any contemporary changes in dune migration rates. A provenance study using heavy mineral analysis and U-Pb dating will be conducted on pre-collected Saharan dune sand samples. The provenance of Saharan sand dunes is an understudied area, largely due to the cost of sample analysis. This study will provide information relating to Saharan sand sea supply and desertification history. The dust emissivity potential of these pre-collected samples will be quantified using a saltation chamber. Moreover, benefiting from the geochemical analysis of the provenance study, this experiment will provide further discourse into whether sand dunes are the major source of mineral aerosols in the Sahara (Crouvi et al., 2012).
