Thesis

Dynamic glaciology of glacier-like forms on Mars

Supervisor(s): Professor Bryn Hubbard and Dr Alun Hubbard

Profile

Stephen graduated from Keele Univeristy in 2010 where he studied Applied Environmental Science and Geography.  It was during his time at Keele, and whilst on study abroad at Brock Univesity (Ontario, Canada), that he was introduced to all things glacial.

This led Stephen to undertake the MSc in Glaciology at Aberystwyth University, graduating in 2012. It was here where he turned to applying glaciological principles to the surface of Mars, and completed his dissertation looking at sediment transport and deposition by glacial-like forms (GLFs) in Mars’ mid-latitudes.

A year later Stephen successfully applied for a PhD in Aberystwyth where he once again spends time analysing the inspirational landscapes of Mars’ mid-latitudes. Stephen is funded through an Aberystwyth University Doctoral Career Development Scholarship (DCDS).

Research

Although over 1300 GLFs have been identified there are a number of fundamental ‘glaciological’ questions which remain unresolved. The most basic of these questions is whether GLFs have ever flowed, like their Earth based counterparts.  Stephen’s project will initially focus on three main aspects: 1) investigating the dynamic glaciology of GLFs; 2) reconstructing the former extent of GLFs in Mars’ mid-latitudes and 3) generating high-resolution digital terrain models (DTMs). This information will then be used to test and guide higher-order models of GLF flow.

Stephen recently visited the Regional Planetary Image Facility at UCL/Birkbeck University to generate a range of DTMs, an example can be found here. These DTMs will be used to help elucidate whether GLFs are, or have previously, flowed.

Research interests

  • Dynamics of GLFs
  • Reconstructing the former extent of GLFs in the mid-latitudes of Mars
  • Sediment transport and deposition in GLFs
  • Formation and effects of basal ice
  • Using remotely sensed data for planetary science investigation
