Dear all,
The University of Tasmania (Australia) is inviting applications for two PhD projects in submarine volcanology and sedimentology. Formal application deadline is mid-October, and candidates should contact me asap. The first project is based on the products of the deep submarine eruption of Havre in 2012 (Kermadec arc). The second project is based on consolidated samples from the IODP Expedition 350 in the IBM rear-arc, and may be linked to other past IODP expeditions.
The candidate selection is highly competitive amongst the University, and we are seeking an applicant with at least one published article in a peer-reviewed journal.
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. Geology and Oceanography at the University of Tasmania have received the maximum grade of 5 in the 2012 Australian ERA rankings (i.e., ‘well above world standard’). The Faculty hosts the world-class ARC Centre of Excellence in Ore Deposits (CODES), and the Central Science Laboratory at the University of Tasmania has world-class geochemical instruments.

Project 1:
Sediment transport during and after the 2012 deep submarine eruption of the Havre volcano (Kermadec arc)
Supervisors: Dr. Martin Jutzeler (U. Tasmania, Australia), Dr. Rebecca Carey (U. Tasmania, Australia) and A/Prof. James DL White (U. Otago, NZ).
Very little is known on the transport and sedimentation processes occurring in association with deep submarine eruptions and their aftermaths. This project aims to: 1) Identify and characterise various syn- and post-eruptive sediment transport associated with the products of the 2012 deep submarine Havre eruption (Kermadec arc). Available data include exceptional ROV video footage, high-resolution bathymetry, and sediment samples collected during a cruise in 2015; 2) Reconstruct the general sedimentation pattern around the Havre volcano, including the various currents in the water column; 3) Analogue sedimentation experiments with mixed components in water tanks and flumes.

Project 2:
Provenance of volcaniclastic units from IODP 350 cores, and creation of a facies-based database for submarine volcaniclastic deposits
Supervisors: Dr. Martin Jutzeler, Dr. Rebecca Carey, Prof. Ray Cas (U. Tasmania)
In 2014, the IODP 350 expedition drilled at proximity of volcanic seamounts in the Izu-Bonin-Mariana rear-arc. This expedition was part of a huge investment from the international Earth science community to understand evolution of volcanic island arcs and formation of continental crust in a global perspective, and through three IODP expeditions. From the collected cores, there is a strong opportunity for outstanding and innovative research on submarine sedimentology and volcanology. IODP Expedition 350 recovered more than 1,800 m of in situ sediments from a volcano-bounded basin and a volcanic apron in the rear of the Izu-Bonin-Mariana arc, giving an exceptional proximal to distal record of submarine volcanic activity during the Miocene to the Quaternary. The cores used in this project would be multiple well-preserved, consolidated volcaniclastic deposits from the lower part of the hole (Units II to VII). This extensive dataset will provide an outstanding record of submarine explosive eruptions, providing temporal constrain on frequency and types of eruptions from underwater volcanoes. It will be the base of a global dataset for submarine volcanogenic facies. This project has large implications on transport and sedimentation processes during subaerial and submarine eruptions, style of submarine volcanism, provenance of sediments, eruption periodicity, etc. Additional research on samples from other IODP expeditions (126, 340) and possible onland deposits (e.g. USA, Japan) is likely.

For interested applicants in either projects, please send your CV, with name and address of 1-2 referees to Martin Jutzeler at: jutzeler@gmail.com
With my best regards,
Martin Jutzeler
