  • A new approach to meteorological observations on remote polar glaciers using open-source internet of things technologies 
    Filhol, Simon; Lefeuvre, Pierre-Marie; Ibañez, Juan David; Hulth, John; Hudson, Stephen; Gallet, Jean-Charles; Schuler, Thomas; Burkhart, John Faulkner (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Key regions of the world lack sufficient infrastructure to collect geophysical observations, often due to logistical challenges such as difficult accessibility and cost. With the advent of Internet-of-Things (IoT) technologies ...
  • Interannual variability of glacier basal pressure from a 20 year record 
    Lefeuvre, Pierre-Marie; Jackson, Miriam; Lappegard, Gaute; Hagen, Jon Ove (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
    Basal pressure has been recorded at the Svartisen Subglacial Laboratory, northern Norway, for 20 years, and is measured by load cells installed at the ice–rock interface under ∼200 m of glacier ice. Synchronous pressure ...
  • Possible impacts of a 1000 km long hypothetical subglacial river valley towards Petermann glacier in northern Greenland 
    Chambers, Christopher; Greve, Ralf; Altena, Bas; Lefeuvre, Pierre-Marie (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Abstract. Greenland basal topographic data show a segmented valley extending from Petermann Fjord into the centre of Greenland; however, the locations of radar scan lines, used to create the bedrock topography data, indicate ...
  • Stress Redistribution Explains Anti-correlated Subglacial Pressure Variations 
    Lefeuvre, Pierre-Marie; Zwinger, Thomas; Jackson, Miriam; Gagliardini, Olivier; Lappegard, Gaute; Hagen, Jon Ove (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    We used a finite element model to interpret anti-correlated pressure variations at the base of a glacier to demonstrate the importance of stress redistribution in the basal ice. We first investigated two pairs of load cells ...
