>>According to a new study, a vital section of the world’s largest ice shelf is losing ice 10 times faster than the overall melt rate for the structure, posing a potential risk to its future stability. The Ross Ice Shelf stretches out over 500,809 km2 (193,363 miles2), and accounts for 32 percent of Antarctica’s total ice shelf area.<<
>>“Previous studies have shown that when ice shelves collapse, the feeding glaciers can speed up by a factor of two or three,” warns Dr. Poul Christoffersen of the University of Cambridge’s Scott Polar Research Institute, who co-authored a new study detailing an important threat to the world’s largest ice shelf.<<
>>The instruments revealed that relatively warm water was flowing into a cavity located beneath the shelf……… It was determined that the water invading the cavity was heated by the Sun in a stretch of open ocean near to the shelf known as the Ross Sea Polyna, which is kept largely free of sea ice thanks to powerful offshore winds. Once warmed, the water was driven into the cavity by a combination of strong winds and tidal forcing.<<
