Glaciers and ice sheets as a biome
Trends in Ecology & Evolution, 2012The tundra is the coldest biome described in typical geography and biology textbooks. Within the cryosphere, there are large expanses of ice in the Antarctic, Arctic and alpine regions that are not regarded as being part of any biome. During the summer, there is significant melt on the surface of glaciers, ice caps and ice shelves, at which point ...

The Antarctic surge theory of Pleistocene glaciation is reexamined in the context of thermal convection theory applied to the Antarctic ice sheet. The ice sheet surges when a water layer at the base of the ice sheet reaches the edge of the ice sheet over broad fronts and has a thickness sufficient to drown the projections from the bed that most ...

Glaciers, ice caps and ice sheets
1985A glacier is an accumulation of ice and snow existing in varying degrees of compaction that moves under its own weight in response to gravitational force. Precipitation in the form of snow adds mass to the system while mass is removed through various ablation processes including surface melting, sublimation and calving of icebergs. In response to these

Stability of ice-age ice sheets
Journal of Geophysical Research, 1961The stability of large ice sheets is investigated by using the present-day theory of the flow of ice in glaciers and ice sheets. The type of instability considered is that first mentioned by Bodvarsson. It is concluded that a small Arctic ice cap can become unstable and expand into a large ice age ice sheet as a result of moderate changes in the regime

The Flow of Ice Sheets and Ice Shelves
1993A brief survey of the mathematical and numerical modelling of ice sheet and ice shelf flows is presented, emphasising the developments over the last decade. For the very slow gravity driven flow of natural ice masses over time scales of thousands of years, the ice is modelled by an incompressible non-linearly viscous fluid with a temperature dependent ...

Ice sheet margins and ice shelves
1984The effect of climate warming on the size of ice sheet margins in polar regions is considered. Particular attention is given to the possibility of a rapid response to warming on the order of tens to hundreds of years. It is found that the early response of the polar regions to climate warming would be an increase in the area of summer melt on the ice ...
