Postdoctoral position - Polar ice, fluid dynamics & carbon

"Investigate how ice sheets impact fluid dynamics beyond present-day ice margins in Antarctica and/or Greenland and their potential impacts on ocean carbon cycling."

Summary

We are looking for a new colleague to join the friendly team at the iC3 polar research hub in Tromsø, the capital of Arctic Norway, for a three-year fixed term postdoctoral position. The overall aim of the project is to constrain the impact of glacial dynamics on fluid transport and release beyond present day ice sheet-margins in Antarctica and/or Greenland and their potential impacts on ocean carbon cycling.

This postdoctoral position is open to qualified applicants of all nationalities. The researcher will have the opportunity to join multidisciplinary programs and research cruise(s). The deadline for applications is June 16th, 2024.

About the iC3 polar research hub

The Centre for ice, Cryosphere, Carbon and Climate (iC3) produces ground-breaking insights into how the links between ice sheets, carbon cycles and ocean ecosystems are impacting life on earth. The centre is based at UiT The Arctic University of Norway, the top university worldwide in terms of Arctic research output, and is partnered with the Norwegian Polar Institute and NORCE. Our team has access to world-class facilities including Arctic and Antarctic research stations, ice-going research vessels and in-house laboratory and modelling capacity.

Candidate profile

The applicant for this postdoctoral job vacancy must document significant experience with seismic data processing and interpretation, as well as integrated geophysical and geological data analyses. Knowledge in geostatistics and numerical modeling would be highly beneficial, as would experience with fluid flow systems on continental margins and glacial dynamics. Applicants must have submitted their PhD thesis before the application deadline.

Polar geophysics

Ice sheet fluctuations across high latitude continental margins are associated with complex geological and physical transformations (e.g. erosion, sedimentation, glacial isostatic adjustments, fracturing, pressure and temperature variations). These transformations impact continental margin hydrology (groundwater) and fluid flow regimes as evidence by post-glacial destabilization of sub-seabed gas hydrates, release of shallow methane stores and discharge of isotopically lighter pore fluids in groundwater releases from now-deglaciated continental margins. The processes involved and the timescales at which they operate, however, remain poorly investigated.

We seek a motivated geophysicist who will integrate geophysical and geological datasets to:

  1. Explore the potential to apply advanced geophysical data analyses to document glacially induced sub-surface fluid transport beyond the present-day ice-margins.
  2. Constrain the processes and timescales involved in such fluid transport.
  3. Build up conceptual models of ice sheet influenced fluid transport and release and its impact on ocean carbon cycling, suitable for implementation in numerical simulations of sub-seabed fluid flow processes.

The post-doctoral fellow will be affiliated with Research Unit 4 within iC3, which studies how past changes in ice sheets affect the global carbon cycle and marine ecosystems. The postdoctoral fellow is expected to be involved in all aspects of the research, including study design, planning, conducting research, data analyses, and publishing results.
