The stability of grounding lines on retrograde slopes
G. H. Gudmundsson,J. Krug,Geoffroy Durand,Lionel Favier,Olivier Gagliardini,Olivier Gagliardini +5 more
TL;DR: In this paper, the stability of marine ice sheets grounded on beds that slope upwards in the overall direction of flow is investigated numerically in two horizontal dimensions, and the authors give examples of stable grounding lines on such retrograde slopes.
Journal ArticleDOI
1-D-ice flow modelling at EPICA Dome C and Dome Fuji, East Antarctica
Frédéric Parrenin,Gabrielle Dreyfus,Geoffroy Durand,Geoffroy Durand,Shuji Fujita,Olivier Gagliardini,F. Gillet,Jean Jouzel,Kenji Kawamura,Nicolas Lhomme,Valérie Masson-Delmotte,Catherine Ritz,Jakob Schwander,Hitoshi Shoji,Ryu Uemura,Okitsugu Watanabe,Naohiro Yoshida +16 more
TL;DR: One-dimensional (1-D) ice flow models are used to construct the age scales at the Dome C and Dome Fuji drilling sites (East Antarctica) as discussed by the authors, where poorly constrained glaciological parameters at each site are recovered by fitting independent age markers identified within each core.
Journal ArticleDOI
Coupling of ice-shelf melting and buttressing is a key process in ice-sheets dynamics
TL;DR: In this paper, the authors investigate the impact of melting below ice shelves and demonstrate that melting acts directly on the magnitude of the buttressing force by modifying both the area experiencing lateral resistance and the ice-shelf velocity, indicating that the decrease of back stress imposed by the ice shelf is the prevailing cause of inland dynamical thinning.
Journal ArticleDOI
A three-dimensional full Stokes model of the grounding line dynamics: effect of a pinning point beneath the ice shelf
TL;DR: In this paper, the authors present a 3D full Stokes model of a marine ice sheet, in which the flow problem is coupled with the evolution of the upper and lower free surfaces, and the position of the grounding line is determined by solving a contact problem between the shelf/sheet lower surface and the bedrock.
Journal ArticleDOI
An updated and quality controlled surface mass balance dataset for Antarctica
Vincent Favier,Cécile Agosta,Cécile Agosta,S. Parouty,Geoffroy Durand,G. Delaygue,Hubert Gallée,A.S Drouet,A. Trouvilliez,Gerhard Krinner +9 more
TL;DR: In this paper, the authors present an updated and quality controlled surface mass balance database for the Antarctic ice sheet, which includes formatted metadata, such as measurement technique, elevation, time covered, etc.
