Tasmania, Australia), Dr. Rebecca Carey (CODES - U. Tasmania, Australia) and Dr. Christian Timms (GNS Science, NZ).* Expedition SO255 dredged the seafloor of the Kermadec intra-oceanic arc and back-arc at multiple locations over >130,000 km2, retrieving pumice and volcanic ash from the shallow seafloor. This project will address dispersal and sediment transport processes from submarine and subaerial silicic volcanism at the scale of an arc. The PhD student will conduct LA-ICP-MS chemical fingerprinting of the volcanic glass and crystals collected during SO255, and compare this data with existing geochemical databases. The style of transport (aerial, as floatsam, or fully underwater) will be inferred using the clastâ??s physical characteristics and the extent of their dispersal. Floatsam dispersion by surface ocean currents will be calculated using oceanic models. This project has large implications on regional sediment provenance, but also on geochemistry and petrology of submarine arc volcanism in general. This project is partly linked to the 2012 deep submarine eruption of Havre, and is likely to be merged with future volcanology projects in the Kermadec arc, including participation to a voyage in 2020. The student would be part of the dynamic Submarine Volcanism Group at the University of Tasmania, and would benefit from a large panel of experts in Earth Sciences in general. The School of Natural Sciences hosts the world-class Centre for Ore Deposit and Earth Sciences (CODES) and Central Science Laboratory. The candidate selection is competitive amongst the School of Natural Sciences; we seek applicants with a published article in a peer-reviewed journal. Interested students should contact Dr. Martin Jutzeler at: martin.jutzeler@xxxxxxxxxxx.
