3-3-3-3-3-3-3-3-3-3-3-3-3 From: James White <james.white@xxxxxxxxxxx> WAS MAGMA-WATER INTERACTION WHAT CAUSED AMBAE'S 2017 ERUPTION TO STOP BUILDING A SMALL CONE AND PRODUCE WIDESPREAD DAMAGING ASHFALL? This project is expected to involve travel to Vanuatu for field sampling of ash successions, coupled with analysis of ash morphology using a range of techniques (microscopy, SEM, xCT, statistical analysis). There are staged goals to the research; characterize in the ash the signature of the change in observed eruption style, and infer the shift in eruptive process that produced this signature. Additional goals are to use ash morphology to provide information on eruption energetics, and to relate the processes of Ambaeâ??s eruption to other eruptions, and other tephra deposits, elsewhere in the world.

We seek applications from high-performing Masters and BSc(honours) students able to compete successfully for a University of Otago doctoral scholarship ( http://www.otago.ac.nz/study/scholarships/database/otago014687.html <https://apc01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fwww.otago.ac.nz%2Fstudy%2Fscholarships%2Fdatabase%2Fotago014687.html&data=02%7C01%7Cjames.white%40otago.ac.nz%7C7ad29f913fb24aea418308d74198030f%7C0225efc578fe4928b1579ef24809e9ba%7C1%7C0%7C637049993507404406&sdata=uNIWqi7oK2mO8B%2BGSJnO2gSRBvoSzxR4eeWR0O%2FqZ9E%3D&reserved=0>). Ability to work in tropical field conditions is needed for fieldwork. Experience with or ability and interest to learn techniques of particle analysis and interpretation are important. The student will be based in the Otago Department of Geology, with co-supervision by Graham Leonard of GNS Science, Avalon office.
