Short summary
Individual Saharan dust particles were investigated by transmission electron microscopy of cross-sectional slices. We classified internal structures, and determined the volume of iron oxide included in the dust particles, the iron content of clay minerals, and the shape of the dust particles. The mineralogical and structural properties of single dust particles provide a basis for the modeling of dust optical properties and the supply of iron as a micronutrient to remote ocean ecosystem.
