AddressABOUT THE ROLE
This role will primarily focus on the identification and characterisation of both visible and non-visible (crypto-) tephra layers preserved in marine and lacustrine sedimentary records from in and around northern Japan. The post holder will be required to sample tephra deposits preserved distally in sediment cores, but also eruption units preserved proximally at volcanic sources.
The main objective of this position is to build a fully integrated and comprehensive eruption records for individual volcanoes, by linking the often fragmentary near-source geological records with the more comprehensive ash fall record preserved in distal sedimentary archives. This will be achieved using detailed chemical fingerprinting of the volcanic deposits and eruptions (e.g., glass chemistry).
The role will be responsible for mapping out the ash fall associated with individual eruptions, integrating these data into ash dispersion models, and contributing to the construction of a chronological frameworks (e.g., 40Ar/39Ar, ZDD), in order to assess the frequency-magnitude relationships of past explosive volcanism along at individual volcanic centres, whilst also assessing the recurrence interval of hazardous and highly disruptive ash fall events.
The selected candidate will hold a PhD in Earth Science or a related discipline. They will evidence experience in technical aspects of Tephrochronology and/or Physical Volcanology as outlined in the job description. They will have experience in the identification of non-visible ash layers (cryptotephra), or will evidence an ability to do so. They will have experience in chemical characterisation of volcanic deposits, specifically using an electron microprobe, and interpreting large igneous chemical datasets. They will evidence an ability to lead and contribute to research outputs in international peer-reviewed journals, and to work effectively and positively within a research team.
