Binge-Purge Cycles of Ice Sheet Dynamics
Binge-purge cycles of ice sheets are based on a hypothesis that ice sheets may exhibit short periods of enhanced ice flow (the purge phase) followed by longer spells of much slower flow (the binge phase). This behavior is thought to be controlled by internal ice sheet dynamics and, hence, may occur under stable environmental conditions. The main application of this hypothesis has been to the Laurentide Ice Sheet, which lay across much of North America during the last ice age (e.g., Siegert, 2001).
