The sheer volume of ice covering Greenland means its fate has global repercussions. 2) Calculate the volume of each ice sheet sheet obtaining ice sheet volumes of 2, all provided in Table 2, 142 cubic kilometers , 315, 29, by multiplying the ice- sheet areas by their average thicknesses, 965 cubic kilometers for Greenland , Antarctica, 604 arctic respectively. Projections of future glacier change, estimates of the available.
The Greenland ice sheet is a major contributor to global sea level rise and plays a crucial role in the surface energy budget, climate and weather of the Arctic. Estimates of the spatial extent of melt across the Greenland ice sheet ( GrIS) are obtained from brightness temperatures measured by the Special Sensor Microwave Imager/ Sounder ( SSMIS. Sea ice surrounding Antarctica reached a new record high extent this year, covering more of the southern oceans than it has since scientists began a long- term satellite record to map the extent in the late 1970s. The Arctic ice pack is the sea ice cover of the Arctic Ocean and its vicinity.
arctic ice sheet volume
The Arctic ice pack undergoes a regular seasonal cycle in which ice melts in spring and summer, reaches a minimum around mid- September, then increases during fall and winter. Arctic ice volume is currently at its highest level in the last 11, 700 years, except for the Little Ice Age ( in the 16th and 17th century), which saw a much higher volume. All other centuries have had lower Arctic ice volume.
