An Iceberg Broken Off In the Antarctic Is Larger Than Bangkok and Weighs 315 Billion Tonnes
9Balance still maintained in the ice shelf
Professor Fricker went on to confirm that there was no relation between the event of the iceberg breaking loose and climate change. She also confirmed that satellite data has shown that the Amery Ice Shelf has been in balance since the nineties and though this was a considerably large piece, still there was no cause for alarm as yet because it is natural or the ice shelves to experience a lot of melting in summer.
“While there is much to be concerned about in Antarctica, there is no cause for alarm yet for this particular ice shelf.”
10The ice shelf is being closely monitored
The Antarctic division of Australia is monitoring Amery closely to see if there is any reaction at all. Some experts feel that the loss of such a huge chunk of ice could change the geometry across the front of the ice shelf influencing the display of behavior of cracks and the stability of the shelf. D28 is 210 meters think and is made up of 315 billion tones of ice. It got its name from the classification system run by the US national ice center that divides the Antarctic into quadrants.
11The iceberg breaking off the Larsen C ice shelf was even larger
The A68 iceberg that broke away from the Larsen C ice shelf in 2017 was in fact much larger than D28 and it also covered an area thrice the size of D28. Now that the iceberg has broken off, it will take several years to melt completely and will be carried westwards by nearshore currents and winds.
12Glaciers and ice streams are thinning.
According to satellite data collected over the last 25 years almost one quarter of West Antarctic Ice sheet is now unstable. Scientists say that ice is being lost in a larger quantity in comparison to what is being replenished by snowfall and some glaciers have also thinned to 120m in certain places. Two of the largest ice streams Pine Island and Thwaites have now risen five times over a period of space observations.
