Postdoc Research Fellow, speleothem paleoclimatology, Bergen, Norway

The Bjerknes Centre for Climate Research and Department of Earth Science at the University of Bergen, Norway, seek a postdoc to work on clumped isotopes and fluid inclusion isotopes in speleothems from Borneo and South Africa.

Logistics

The position is for a fixed term of three years and is associated with the T-TRAC project and SapienCE (Centre for Early Sapiens Behaviour), a new centre of excellence (both financed by the Norwegian Research Council).

Preferred starting date is 1 September 2018.

Description

The postdoctoral fellow will be part of a team reconstructing past temperatures from speleothems from Borneo and South Africa. Our team are applying state-of-the-art techniques such as fluid inclusion microthermometry, clumped isotope thermometry, and fluid inclusion isotope analysis. The postdoctoral fellow will take part in building a new fluid inclusion extraction line for isotope analysis using our existing Picarro instruments and will be responsible for the clumped isotope thermometry and fluid inclusion isotope measurements in selected samples.

For our Borneo research, these methods have been successfully applied to a pilot sample, and will now be used to derive paleo-temperatures across the last 500,000 years within the T-TRAC project. We will mostly work on previously studied, well-dated speleothem samples, but in addition will strive to close a remaining time gap in the record. To this end, the postdoctoral fellow will perform U-Th dating of candidate stalagmites in collaboration with Professor Jess Adkins at the California Institute of Technology that will incorporate a research stay at this institute within the first year.

Analysis of the speleothems from South Africa is aimed at reconstructing paleo-environmental conditions during the period 100-50 ka, in collaboration with archaeologists in the framework of the transdisciplinary SapienCE SFF Centre of Excellence. Current archaeological evidence highlights 100-50 ka as being a watershed for human cognitive, technological and social developments in Africa. More research is needed to understand where, when and why early humans started to think and behave like we do today. Improved understanding of the environmental conditions such as climate change under which these developments occurred is a critical piece of this puzzle.

The postdoctoral fellow will have the opportunity to take part in fieldwork in South Africa and/or Borneo. The affiliation of this position with both the Bjerknes Centre for Climate Research and SapienCE will offer ample opportunities for cross-disciplinary exchange and collaboration.
