Record #165737:

Signature of paleo-ice stream stagnation: till consolidation induced by basal freeze-on / Poul Christofferson, Slawek Tulaczyk.

Title: Signature of paleo-ice stream stagnation: till consolidation induced by basal freeze-on / Poul Christofferson, Slawek Tulaczyk.
Author(s): Christofferson, Poul.
Tulaczyk, Slawek.
Date: 2003.
In: Boreas. (2003.), Vol. 32(1) (2003)
Abstract: Investigates possibility of till consolidation driven by basal freeze-on beneath a stagnating, mid-latitude palaeo-ice stream. Focuses on Baltic Ice Stream, advancing into Denmark ca. 15 ka BP. Adapts concepts from frost heave simulations in permafrost engineering to develop 1-D numerical model coupling ice-stream dynamics to transient changes of sub-ice-stream till properties. Model includes pore-water flow driven by hydraulic gradients induced by supercooling of ice base. Predicts postglacial till strength profiles using SHANSHEP method. Shows that, despite a relatively mild palaeo-climate, bases of mid-latitude palaeo-ice streams may have experienced period of basal freezing due to horizontal advection of cold ice. In special issue Palaeo-ice streams.
