Afro-Arabian desert belt export at least half of the world's dust. Dust provides essential minerals for life to thrive on Earth, both on land and in the sea. Dust provides iron to the ocean, which is one of the main limiting nutrients for photosynthetic algae. However, not much is known about how much dust is necessary to fertilize the ocean. The aim of the project is to analyze dust particles within marine sediments from Al Wajh lagoon, NE Red Sea. A sedimentological, mineralogical, and spatial analysis will be performed.
