Recently, the National Centre for Polar and Ocean Research (NCPOR)predicted an increase in the expansion of Ameri Ice Shelf (AIS) boundaries by 2021.

  • Recently, the National Centre for Polar and Ocean Research (NCPOR)predicted an increase in the expansion of Ameri Ice Shelf (AIS) boundaries by 2021.
  • Amery is the third largest ice shelf in Antarctica, and is a key drainage channel for the east of the continent.
  • The shelf is essentially the floating extension of a number of glaciers that flow off the land into the sea.
  • It is part of  Robertson Land.
  • It is located on the east coast of Antarctica, at about 70ºS Latitude, 70ºE Longitude.

Predictions

  • There would be a 24 per cent increase in the expansion of the Ameri Ice Shelf (AIS) boundaries in Antarctica by 2021 and another 24 per cent by 2026 from its 2016 positions, the National Centre for Polar and Ocean Research (NCPOR) in Goa has predicted.
  • The prediction made by NCPOR is based on a 16-year-long satellite-based observation that covered an area of 60,000 sq km across the AIS.
  • This study would help understand the ongoing changes in the ocean and atmospheric forcing better.
