1-1-1-1-1-1-1-1-1-1-1-1-1-1 From: Martin Jutzeler <jutzeler@xxxxxxxxx> The University of Tasmania (Australia) is inviting applications for *one fully funded PhD project* *on submarine silicic volcanism*. The student will be part of an international team aiming at understanding the behaviour of submarine silicic caldera eruptions and their impacts, using data from Macauley caldera and other submarine volcanoes in the Kermadec arc/RangitÄ?hua. The overarching project will determine the conditions that lead to caldera formation and explosive eruptions underwater, the dynamics of associated sediment flows, and under what conditions can these events trigger tsunami. Expected outcomes include an unprecedented reconstruction of the architecture of submarine caldera volcanoes, regional chronostratigraphic reconstructions, new innovative models applicable globally for a richer understanding of volcanic tsunami and eruptions that shape the seafloor, and natural hazard mitigation. *Project : Submarine Caldera-Forming Eruption at Macauley, Kermadec Arc/RangitÄ?hua * *Supervisors*: Dr Martin Jutzeler; A/Prof. Rebecca Carey (University of Tasmania, Australia). We are seeking a PhD student in volcanology to undertake this 3.5-year PhD project. The PhD project aims at studying the volcanic facies and geochemistry of the 6.4 ka caldera-forming silicic eruption of Macauley volcano, Kermadec arc/RangitÄ?hua. The now submarine Macauley caldera produced enormous submarine pumiceous sediment waves on its flank, in addition to complex pyroclastic density current deposits on the adjacent Macauley Island. The project dataset will be based on an onland expedition on the very remote Macauley Island (pending iwi permission to access the Island) to which the student will participate, and already collected sediment core samples from the submarine wave deposits. The student will have the rare opportunity to undertake a combined fieldwork and marine core-based study on outstanding volcanic deposits that possibly record subaerial-to-submarine transition during a caldera-forming eruption. The student will interpret eruption, transport and sedimentation processes based on combination of field and laboratory-based stratigraphic, (micro)textural and geochemical datasets. The candidate should have a sound background in volcanic facies analysis, igneous geochemistry, command of scientific writing and the ability to conduct fieldwork in remote and difficult conditions. *The 3.5-year project is fully funded by an ARC Discovery Project grant and the University of Tasmania. The student will be provided a Living Allowance scholarship of AU$31,500 per year, fully covered domestic/international tuition fees, and up to AU$2,000 relocation fees.* *Prospective students should contact Dr Martin Jutzeler by the **15 January **for a scholarship starting in early 2024.* The student would be part of the dynamic Volcanology Group at the University of Tasmania. The School of Natural Sciences hosts the world-class Centre for Ore Deposit and Earth Sciences (CODES) and Central Science Laboratory. The student will also benefit from national and international advisors, including Prof. Stephen Gallagher at U. Melbourne, Dr. Steffen Kutterolf at GEOMAR, Prof. Michael Manga at UC Berkeley, Dr Emily Lane at NIWA, Prof. Y. Yokoyama at U. Tokyo, and others. Tasmaniaâ??s breathtaking landscapes, pristine beaches, and abundant wildlife create an awe-inspiring environment to explore and appreciate. There are endless opportunities for outdoor adventures, hiking, surfing, and sightseeing. Hobart is a lovely small city snuggled between the wilderness of forested mountains and the vast Southern Ocean. We have a rich cultural scene, with a thriving arts community, museum and art galleries, and various festivals and events throughout the year. The city's historic charm is evident in its well-preserved Georgian buildings, where bustling markets, cafes, bars and restaurants can be found. Embracing the slower pace of life, the student will find Hobart to be a place of warmth (despite the cool climate) and authenticity. Interested candidates should *first* send their CV to Dr Martin Jutzeler before officially applying through the UTAS website. martin.jutzeler@xxxxxxxxxxx 1-1-1-1-1-1-1-1-1-1-1-1-1-1 ------------------------------
