    • Automated mapping of glacial overdeepenings beneath contemporary ice sheets: Approaches and potential applications 

      Patton, Henry; Swift, Darrel A.; Clark, Chris D.; Livingstone, Stephen J.; Cook, Simon J.; Hubbard, Alun Lloyd (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-01-17)
      Awareness is growing on the significance of overdeepenings in ice sheet systems. However, a complete understanding of overdeepening formation is lacking, meaning observations of overdeepening location and morphometry are urgently required to motivate process understanding. Subject to the development of appropriate mapping approaches, high resolution subglacial topography data sets covering the whole ...

    • Distribution and characteristics of overdeepenings beneath the Greenland and Antarctic ice sheets: Implications for overdeepening origin and evolution 

      Patton, Henry; Swift, D.A.; Clark, C.D.; Livingstone, Stephen J.; Cook, S.J. (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-09-15)
      Glacier bed overdeepenings are ubiquitous in glacier systems and likely exert significant influence on ice dynamics, subglacial hydrology, and ice stability. Understanding of overdeepening formation and evolution has been hampered by an absence of quantitative empirical studies of their distribution and morphology, with process insights having been drawn largely from theoretical or numerical studies. ...
