New MSc Geochemistry
A new 2-year, part-time MSc Geochemistry degree will be offered starting in September 2015. We encourage applicants with at least a 2:2 degree in a related science to apply. Please follow this link to find out more and to apply.
Three new Papers published
Three new papers have been published by Karen, her research group and colleagues. These are:

NERC Urgency Grant
Karen Hudson-Edwards and colleagues from Aberystywyth University, Bangor University, Liverpool John Moores University and the University of Northern British Columbia, Canada, have received a NERC Urgency grant to work on the project 'The environmental impact of the Mount Polley mine tailings spill and related clean-up operations, British Columbia, Canada'. The spill, which occurred on August 4th, 2014, resulted in the discharge of 10 million m3 of water and 4.5 million m3 of copper-, selenium- and vanadium-bearing tailings to local waterways. The team will investigate the geochemical stability and reactivity of the spilled tailings, and the the impacts of the spill and related clean-up operations on longer-term recovery of terrestrial and aquatic environments. Look h for photos of the spill.
Open-access paper on ancient African fish dust fertilising the Amazon
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.
