Dr. Sarah Southern

Postdoctoral Research Fellow (Completed)

Research Topics

  • Principally my research concerns deep-water sedimentology: examining the fundamental processes that are associated with a spectrum of sediment gravity flow types (slides, debris flow and turbidity currents), and how they are preserved in the geological record.
  • Understanding sediment gravity flows that are transitional between turbulent and cohesive; examination of the character and distribution of their deposits with respect to sea-floor topography (PhD thesis - request by email). 
  • Examination of the internal architecture and heterogeneity of slope channels in order to understand variations in sedimentary processes (erosion, bypass and deposition) and the implications for reservoir characterization.  Specific themes include: 
    • Characterization of channel-base deposits at different scales of channelization (Tres Pasos Formation) – ongoing research in 2016.  
    • Qualitative and quantitative characterization of slope channel fill position (axial through to marginal) using over 100 logged sections of individual slope channel fills (Tres Pasos Formation) – ongoing research in 2016.
