GRISLI (GRenoble Ice-Shelf and Land Ice) is a three-dimensional ice sheet model accounting for thermodynamical coupling between ice velocities and temperatures. GRISLI runs at 40 km × 40 km resolution and simulates both grounded and floating ice, by considering three types of ice flow: ice sheets, ice streams, and ice shelves.
GRISLI was initially developed for and validated over Antarctica by Ritz et al. (2001). It has since then been successfully applied to study the mechanisms that drove Heinrich events (last 80 ka ; Alvarez-Solas et al., 2011, 2013), the inception of the Fennoscandian ice sheet during the last glacial period (90 ka ; Peyaud et al., 2007), the partial melt of the Greenland ice sheet during the last interglacial period (130–115 ka ; Quiquet et al., 2013), and the continental-scale initiation of the Antarctic ice sheet at the Eocene-Oligocene boundary (34 Ma ; Ladant et al., 2014).
I used this model to investigate the mechanisms responsible for glacial onset during the Ordovician, 450 million years ago.
