The Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research (AWI) is a member of the Helmholtz Association (HGF) and funded by federal and state government. AWI focuses on polar and marine research in a variety of disciplines such as biology, oceanography, geology, geochemistry and geophysics thus allowing multidisciplinary approaches to scientific goals.

PostDoc "Geophysical glaciology of Thwaites Glacier, West Antarctica" (m/f/d)

Background

Thwaites Glacier in West Antarctica has nearly doubled its flux in the last thirty years. The rheology and topography of the bed affect how quickly ice retreats and thus contributes to global sea-level rise. As part of the US-UK-led International Thwaites Glacier Collaboration, AWI are collaborators in the ice- and modeling-based project GHOST to examine the bed and interior of Thwaites Glacier – whether it could rapidly collapse, raising sea level by more than 3 meters, or whether the retreat might slow or pause.

As part of a team of geophysicists and modelers working closely to determine the highest priority survey targets and data needs from the field, this project will provide continuous active seismic data to yield profiles of bed topography and characterization of bed properties at high spatial resolution. The data will be used to improve reconstructions of past dynamics and model projections of future behavior sea-level rise.

The position is part of our recruiting initiative AWI INSPIRES - INternational Science Program for Integrative Research in Earth Systems. AWI INSPIRES aims at strengthening our new research program “Changing Earth, Sustaining our Future”. Details about all open positions and the general application requirements can be found at

Tasks

You will
collate subglacial properties of Thwaites from literature studies and from project partners to prepare for on-site data processing and interpretation;

participate in the field deployment of AWI’s active vibroseismic source/snowstreamer system as part of the GHOST traverse (Nov 2020 – Feb 2021 and Nov 2021 – Feb 2022). This will include data processing in the field for quality control and provide the basis for decision making.

  • perform post-field season seismic data processing
, providing a seismic image of the ice internal structure and sub-surface, in the depth domain. This will allow analysis of seismic event attributes (e.g. sediment seismic wave speed, reflection coefficients, phase changes);

Interpret field data
provide a comprehensive characterization of the subglacial properties of Thwaites Glacier and publish the results.

Requirements

  • Proven expertise and a PhD (or equivalent) in the field of geophysics, geosciences, physics or related disciplines.
  • Well-founded knowledge in glaciology and scientific experience with active source seismology.
  • Previous experience in application of seismology on ice sheets and glaciers is an asset.
  • Distinct interest in the scientific exchange and communication with the project members and interdisciplinary collaborators is expected.
  • Good language skills in spoken and written English
