On an otherwise featureless ice shelf, crevasses show where the different ice flows merge as they flow towards the open sea. "The area was covered in at least five to six feet of snow - the piled-up snow ultimately gave way triggering the avalanche," he said. They most often occur where the flow of a glacier increases, like in a steep deepening valley, and are thus oriented perpendicular to direction of flow. Knowledge of the crevasses' distribution is critical for understanding the glacier and ice shelf stability. Were certain that the warming of ocean water is melting from underneath the floating ice shelves around Antarctica, and we predict that the warming atmosphere will lead to more melting and calving, but how much global warming-caused ice loss might there be within the next five years?

The weather will be fairly harsh even without the ice (six month seasons of summer sun and winter darkness), and Antarctica gets little precipitation, so will be quite dry and arid. Its best to travel quickly through vulnerable areas and avoid the time of exposure to ice and serac fall (which is more a result of glacier movement and gravity than daily temperature fluctuations) to avoid ice and serac fall. As brittle fractures open they propagate downward, producing gashes in the glacier that are known as crevasses.
