    • Ice Thickness and Bed Elevation of the Northern and Southern Patagonian Icefields 

      Millan, Romain; Rignot, Eric; Rivera, A; Martineau, Vincent; Mouginot, Jérémie; Zamora, Rodrigo; Uribe, Jose; Lenzano, G; de Fleurian, Basile; Li, Xin; Gim, Yonggyu; Kirchner, Donald L. (AGU, 2019)
      The Northern and Southern Patagonian Icefields are the largest ice masses in the Southern Hemisphere outside Antarctica, but their ice volume and bed topography are poorly known. Here, we combine airborne gravity data ...

    • The role of subglacial hydrology in ice streams with elevated geothermal heat flux 

      Smith-Johnsen, Silje; de Fleurian, Basile; Nisancioglu, Kerim Hestnes (Cambridge University Press, 2020-02-10)
      The spatial distribution of geothermal heat flux (GHF) under ice sheets is largely unknown. Nonetheless, it is an important boundary condition in ice-sheet models, and suggested to control part of the complex surface ...

    • Sensitivity of the Northeast Greenland Ice Stream to Geothermal Heat 

      Smith-Johnsen, Silje; Schlegel, Nicole; de Fleurian, Basile; Nisancioglu, Kerim Hestnes (Wiley, 2019-12-20)
      Recent observations of ice flow surface velocities have helped improve our understanding of basal processes on Greenland and Antarctica, though these processes still constitute some of the largest uncertainties driving ice ...

    • SHMIP The subglacial hydrology model intercomparison Project 

      de Fleurian, Basile; Werder, Mauro A.; Beyer, Sebastian; Brinkerhoff, Douglas J.; Delaney, Ian; Dow, Christine F.; Downs, Jacob; Gagliardini, Olivier; Hoffman, Matthew J.; Hooke, R. LeB.; Seguinot, J.; Sommers, Aleah (Cambridge University Press, 2018-10-24)
      Subglacial hydrology plays a key role in many glaciological processes, including ice dynamics via the modulation of basal sliding. Owing to the lack of an overarching theory, however, a variety of model approximations exist ...

    • Simulated retreat of Jakobshavn Isbræ since the Little Ice Age controlled by geometry 

      Steiger, Nadine; Nisancioglu, Kerim Hestnes; Åkesson, Henning; de Fleurian, Basile; Nick, Faezeh M. (Copernicus Publications, 2018-07-12)
      Rapid retreat of Greenland's marine-terminating glaciers coincides with regional warming trends, which have broadly been used to explain these rapid changes. However, outlet glaciers within similar climate regimes ...

      Steiger, Nadine; Nisancioglu, Kerim Hestnes; Åkesson, Henning; de Fleurian, Basile; Nick, Faezeh M. (European Geosciences Union, 2018-07-12)
      Rapid retreat of Greenland's marine-terminating glaciers coincides with regional warming trends, which have broadly been used to explain these rapid changes. However, outlet glaciers within similar climate regimes experience ...
