PhD Position University of Bern – Geochemical fingerprinting of volcanic eruptions in ice cores

Michael Sigl

PhD Position in Geoscience/Geochemistry/Paleoclimatology/Physics or related field

Unlocking eruption source parameters of ancient volcanic eruptions using ice cores

A PhD position is available at the division of Climate and Environmental Physics (CEP) at the Physics Institute, University of Bern in Switzerland. This PhD project is part of the European Research Council Consolidator Grant, “Timing of Holocene volcanic eruptions and their radiative aerosol forcing (THERA)”.

The announced PhD position is for 4 years. The preferred starting date is October, 2019.

The goal of the THERA project is to extract data on the timing, magnitude and source location of the major volcanic eruptions that occurred during the Holocene (i.e., the past 12,000 years). THERA is focusing on developing a state-of-the-art reconstruction of volcanic aerosol forcing on global climate using novel analytical tools and an array of deep ice-cores from Greenland and Antarctica.

The PhD student will apply 1) sulfur isotopes (33S, 34S) as a tool for constraining plume injection heights, 2) investigate high-resolution glaciochemical archives of ash and aerosol delivery to elucidate eruption proximity, and 3) undertake detailed tephra sampling and geochemical analyses for fingerprinting provenance. The PhD student will integrate the developing ice-core tephrochronology into regional tephrochronological frameworks from both hemispheres allowing to study the size/frequency distribution of volcanism in different regions since the last ice age.

Qualification requirements

-              strong analytical skills and a Master’s degree in physics, chemistry, geosciences (or related)

-              fluent spoken and written English are prerequisites for this position

-              excellent collaboration skills and ability to successfully join in academic teamwork within and across disciplines

-              experience in the use of geochemical analytical techniques or tephra analyses is advantageous

-              some experience in statistics, database management and programming would be beneficial

We offer

-              a fully-funded position for 4 years (salary according to Swiss National Science Foundation rules)

-              a professionally stimulating working environment in a small team

-              the student will benefit from the support of an active, interdisciplinary research environment. The PhD students will work alongside members of the Continuous Flow Analyses Laboratory, the Oeschger Centre of Climate Change Research (OCCR) and international project partners (e.g., St Andrews Isotope Geochemistry, UK)
