If you know good students who could be able to manage such a project here in Clermont, please let me know. ------------------------------ -------------------- Seven years after the 2004 Indian Ocean tsunami, the sedimentary record of palaeotsunamis worldwide is getting more and more documented, and scientists have now access to a complete proxy toolkit, including sedimentological, micropaleontological, geochronological and geochemical methods. This multidisciplinary approach allows determining paleoenvironments before, during and after the tsunami, even if one or more proxies may lack depending on the local setting. Despite considerable progress in palaeotsunami research, distinguishing tsunami from storm deposits is still complex, and reconstructing a past tsunami after its deposits remains difficult. Information given by the grain-size distribution, paleontological and geochemical analyses of bulk samples from onshore tsunami deposits have limitations due to (1) the destruction of sedimentary structures of these unconsolidated sediments and (2) the subjectivity and low resolution of manual sampling on the field. Furthermore, the structure and vertical grain-size trends of tsunami deposits are rapidly modified by bioturbation. This PhD project aims at developing high-resolution X-ray tomography (Paris et al., submitted) as a tool for better characterise the texture and microstructure of tsunami deposits (e.g. internal structure, clast fabric, grain-size micro-variations). Dataset are already available and include Krakatau 1883, Lisbon 1755 and Karymsky Lake 1996 tsunamis. ------------------------------------------------------------------------------ Start date: September-October 2012 Duration: 3 years Supervisor: -- Raphaël Paris Laboratoire Magmas et Volcans UMR 6524 CNRS - UBP - IRD 5 rue Kessler 63038 Clermont-Ferrand, FRANCE tel. +33 (0)4 73 34 67 17 email.
