Job description:Master thesis: Antarctic marine sediment chronologies

Research division: Marine Geochemistry/ Marine Geology

As part of the INSPIRES-funded project “Past Antarctic sea ice – ice shelf interactions”, we are looking for a Masters student to work on sediment cores collected in the Weddell Sea, Antarctica.

The goal of the project is to establish robust age models for marine sediment cores by the application of radiometric methods (230Thex, 231Paex/230Thex). These chronologies are the base for paleoenvironmental reconstructions focusing on changes in sea ice coverage and how they relate to glacial-interglacial climate variability.
This is a geochemical project, performed mostly in a state-of-the-art specialized lab environment. It will require the handling of hazardous substances. Training will be provided.

  • Sample preparation for geochemical analysis
  • Performing microwave assisted acid digestions
  • Separation and measurement of various natural radioactive isotopes and elements in marine sediments (SF-ICP-MS and ICP-OES)

  • Basic experience in lab work
  • Interest in quantitative aspects of physics, chemistry, geology and biology
  • Ability and willingness to handle hazardous substances, while reliably following instructions and safety measures
  • willingness to work in an interdisciplinary team
