Karen Hudson-Edwards has published an describing the solid-phase speciation of phosphorus in dusts and source sediments of the Saharan Bodélé Depression in Chad, the dustiest place on Earth. This work was carried out with colleagues Professor Charlie Bristow (Birkbeck), Dr Giannantonio Cibin (Diamond Light Source), Mr Gary Mason (Birkbeck) and Dr Caroline Peacock (Leeds). The paper describes, for the first time, the occurrence of relatively soluble fish bone and teeth in aeolian dusts. The Bodélé dusts have been shown to fertilise the equatorial Atlantic Ocean and the Amazon.
