1-1-1-1-1-1-1-1-1-1-1-1-1-1 From: Martin Jutzeler <martin.jutzeler@xxxxxxxxxxx> *** 3 PhD opportunities at University of Tasmania, Australia *** Three exciting PhD projects in submarine volcanology are available at the University of Tasmania, Australia. Two projects would start by mid-2020, and the two students will be part of a 1-month voyage aboard the research vessel RV Investigator in October-November 2020. The voyage will survey three large submarine calderas in the Kermadec arc, north of New Zealand. The overarching aim of the research is to quantify the magma flux of submarine silicic eruptions at various vent water depths, by using the morphology of giant proximal sediment waves (anti-dunes) deposited by pumice-rich eruption-fed sediment flows. The project will include volcanic architecture reconstruction and to assess thresholds in intensity and style of eruptions in the context of deep-water caldera-forming silicic volcanism. This threshold framework will provide a benchmark assessment of the tsunamigenic potential of submarine volcanism. Collaboration with international teams will be key for this research program. - Project 1 will be based on processing and interpretation of seismic reflection surveys, ship-based sub-bottom profiler and multibeam bathymetry. Applicants should have strong background knowledge on seismic data processing and interpretation using the Kingdom suite software. - Project 2 will focus on description and interpretation of volcanic and sedimentary textures based on sediment cores, and interpretation/modelling of sediment fluxes. Applicants should have good knowledge in eruption and sedimentary processes. Core logging experience would be an advantage, but is not necessary. Project 3 can be started in early 2020, and involves geochemical fingerprinting of submarine-deposited volcanic products in the Kermadec arc. The project would reconstruct sedimentation patterns at the scale of the arc, and would include regional atmospheric and ocean current dispersal analysis. Distal pumice-raft deposits from Havre 2012 eruption will be a focus of this project. The project is based on dredged samples from SO-255 voyage in the Kermadec arc in 2017, in addition to other legacy voyages between New Zealand and Australia. The student will actively participate to future voyages onboard the RV Investigator as well, from which he/she will acquire part of the sample dataset. The Volcanology Group at the University of Tasmania has a strong focus on modern and ancient submarine volcanology. The students will be part of a vibrant group focussing on understanding eruption and transport processes in subaerial and marine environments. Our geochemical laboratories include state-of-the-art SEM, EPMA, XRD and LA-ICP-MS instruments that are accessible to our students. Hobart and Tasmania are reputed for their lifestyle, pristine coasts and beaches, and access to wilderness. The climate is temperate to oceanic and not comparable to mainland Australia. The University of Tasmania offers full scholarships for domestic (Australia + New Zealand) and international students; domestic students (Australia and New Zealand) are strongly encouraged to apply as these scholarships are less competitive. Selection of applicants is highly competitive amongst the School of Natural Sciences, and international applicants should be author or co-author of a published or accepted paper in a peer-reviewed journal. The length of the PhD project is 3.5 years and is research intensive. Interested students should send their CV by end of January 2020 to Dr. Martin Jutzeler: martin.jutzeler@xxxxxxxxxxx 1-1-1-1-1-1-1-1-1-1-1-1-1-1 ============================================================== Volcano Listserv is a collaborative venture among Arizona State University (ASU), Portland State University (PSU), the Global Volcanism Program (GVP) of the Smithsonian Institution's National Museum of Natural History, and the International Association for Volcanology and Chemistry of the Earth's Interior (IAVCEI).
