●Expansion of the Amery Ice Shelf(AIS)
•Amery Ice Shelf(AIS) is one of the largest glacier drainage basins in the world, located on the east coast of Antarctica [at about 70ºS Latitude, 70ºE Longitude. ]
•The AIS dynamics and mass balance help in understanding the changes in the global climate scenario.
•The National Centre for Polar and Ocean Research (NCPOR) predicts that there would be a 24% increase in the expansion of Amery Ice Shelf (AIS) boundaries by 2021 and another 24% expansion by 2026 from its 2016 positions
•The predictions are based on a 16-year-long satellite-based observation that covered an area of 60,000 sq. km across the AIS.
•In the background of the global warming scenario, the study reveals about the advancement in the predicted ice shelf extent, the future dynamism of ocean heat fluctuation and Antarctic Amery ice shelf mass shifting-extent.
•The study has also observed that the critical cooling of the Sea Surface Temperature (SST) is resulting in an advancement of the ice shelf by 88% in the past 15 years.
[These changes would contribute in a major way to climate variability.]
