PhD, glacial geomorphology, sedimentology & geophysics, Stockholm, Sweden

Stockholm University is looking for a new PhD student to join a group assessing the past, present and future stability of the Hardangerjøkulen ice cap in southern Norway, which is a collaborative venture with the University of Leeds.

Description

Bedforms within a glacier foreland are widely used to interpret glacier and palaeoglacier dynamics. However, the internal structure and preservation of depositional landforms in the foreland after ice retreat is dependent on several factors including post depositional process such as slumping, fluvial erosion, underlying topography, ice core melt-out, the morphological proportions of individual landforms and - crucially - the mechanical properties of the sediment that comprises the landform.

If landform assemblages are to be used to interpret glacier dynamics it is important to determine sediment structure and mechanical properties across the glacier foreland as this will have a significant impact on the preservation potential of these features and thus interpretations made relating to glacier dynamics.

Traditional sedimentological techniques often provide only limited information on internal structure of glacial landforms and qualitative descriptions of glacial sediment mechanical properties. However, geophysical data can provide information on structure of the subsurface at different scales and quantitative data on sediment mechanical properties which can then be compared to sedimentological and geomorphological field data.

Midtdalsbreen, an outlet glacier of the Hardangerjøkulen ice cap in southern central Norway, has a suite of glacial landforms that appear to have been variably preserved through time due to changing glacier dynamics that in turn produces sediments with different structural and mechanical properties. This project would acquire a suite of geophysical data in the foreland of Midtdalsbreen, including (but not limited to) seismic refraction, surface wave and electrical resistivity methods, to interpret the structure, extent and mechanical strength of glacial sediments. The project would also collect both sedimentological and geomorphological data from the glacier foreland to compare with seismic data. Seismic, sedimentological and geomorphological data would be collected over a minimum of two field campaigns to Finse, Norway.

The PhD candidate will work in close collaboration with Dr Adam Booth and Dr Bill Murphy at the University of Leeds with the possibility of a placement in Leeds during the project period dependent on success of external funding applications. In addition, funding will also be sought to support participation in courses at the University Centre in Svalbard (UNIS) to gain an overview of glaciological processes and field techniques.
