31. Ice streams are a type of glacier.32. Seen from the air, the ice streams are scarred lengths of ice crushed and stretched into deep crevasses. 33. It is one of several major ice streams draining from Marie Byrd Land into the Ross Ice Shelf. 34. The inter-stream ridges are frozen to the bed while the bed beneath the ice streams consists of water-saturated sediments. 35. One ice stream begins just underneath this remote field camp in the middle of the West Antarctic ice sheet. 36. But the behavior of ice streams and the coastal ice shelves into which they flow is complex and unpredictable. 37. Parts of this ice sheet form moving glaciers known as ice streams , which flow towards the edges of the continent. 38. The long, narrow Erebus ice stream drains from the western slope of Mount Erebus, an active volcano rising in elevation. 39. The ice streams flow along relatively narrow basins made slippery by a combination of fine sedimentary particles and melted ice water. 40. In Antarctica, the seismic waves from the earthquake were reported to have caused the Whillans Ice Stream to slip by about.
