The pine island glacier
Webb2 jan. 2014 · Pine Island Glacier (PIG), a major outlet glacier feeding one such ice shelf, has shown apparently continuous thinning (5, 6) and intermittent acceleration (7–9) from 1973 to 2009. During this period, its ice shelf has also thinned ( 6 , 10 – 12 ), and the reduction in buttressing driven by oceanic melting is believed to be responsible for the … Webb23 nov. 2016 · It is a marine-terminating glacier, which means its front flows off the land and pushes out into the ocean along the seafloor until its mass begins to lift up and float.

Webb22 mars 2024 · Abstract. Pine Island Glacier (PIG) has recently experienced increased ice loss mostly attributed to basal melt and ocean-ice dynamics. However, atmospheric forcing also plays a role in the ice mass budget, as besides lower-latitude warm air intrusions, the steeply sloping terrain that surrounds the glacier promotes frequent Foehn winds. An …
Pine Island Glacier (PIG) is a large ice stream, and the fastest melting glacier in Antarctica, responsible for about 25% of Antarctica's ice loss.
