Thawing coastal and subsea permafrost, disintegrating methane hydrates and deep petroleum reservoirs are releasing methane to overlying water and atmosphere on the shallow yet extensive East Siberian Arctic Ocean, the World’s largest shelf sea system. There is a large uncertainty of the relative contributions of these sources, how this subsea system operates, and the fate of the released methane. The project offers the possibility to source apportion the methane currently being vented from the subsea system by applying triple-isotope fingerprinting of methane from Arctic samples, some already collected others to be collected in the near future on international field campaigns. Targeted samples are from both subsea permafrost drillcores, from ship-based collection of seawater, and from both shipboard and land/island-based observatory collections of air. In addition to possible field work, the position involves active work on vacuum and gas handling systems, laser spectroscopy and gas chromatography – (isotope) mass spectrometry.
Postdoctoral positions are appointed primarily for purposes of research. Applicants are expected to hold a Swedish doctoral degree or an equivalent degree from another country.
We are seeking a highly motivated person with a completed Ph.D. within the Earth, Atmospheric or Environmental Sciences, Chemistry or Engineering. Your skills may come from experience in organic geochemistry, isotope geochemistry, deep earth gas geochemistry, atmospheric gas/isotope measurements or related fields. Practical experiences with gas chromatography, laser spectroscopy, and/or isotope mass spectrometry are useful. Handling of gas separation systems, instrumental development and tinkering, and field sampling are also all beneficial. A high emphasis is placed on well-developed proficiency in scientific writing. Collaborative skills are also important as the post-doc will work together tightly in a team and be centrally engaged in international collaborations.
The degree should have been completed no more than three years before the deadline for applications. An older degree may be acceptable under special circumstances, which may involve sick leave, parental leave, clinical attachment, elected positions in trade unions, or similar.
