Across the Brunt Ice Shelf several cracks are appearing on the northern shoreline of Antarctica. The cracking ice rack is anticipated to shelf an iceberg soon that is about double the size of New York City. The fate of whatever remains of the ice rack does not appear encouraging, either. On the 20th of Feb, images were shared by NASA Earth Observatory of the ice rack, looking at a satellite view from the month of Jan. 23 to another picture captured on the 30th of January, 1986. In the 2019 photograph, a long crack can be seen winding from the south to the north and crossing a large portion of the rack. Earth Observatory explained that given the name “the Halloween crack” due to the appearance in October 2016 — reaches out from the west to the east along the highest point of the picture.
However, the crack which is travelling northward is progressively troubling, as it is presently extending by about 3 miles (4 kilometers) each year. That break has a long way to go before it achieves the Halloween split. When that happens, the rack will discharge a chunk of ice estimating around 660 square miles which is 1,700 square km; more than double the zone of New York City’s five districts and the greatest iceberg to isolate from Brunt Ice Shelf since 1915, as indicated by Earth Observatory. A glaciologist at NASA’s Goddard Space Flight Center, Joe MacGregor explained to Earth Observatory that relying upon where the breaks consolidate, the strength of the whole rack could be imperiled. Increasing worldwide temperatures have quickened the loss of ice in Antarctica, with the solidified landmass bringing forth numerous sizable chunks of ice as of late. One transcending berg that isolated from the Larsen C Ice Shelf in July 2017 was assessed to be about the span of Delaware, and a significantly greater chunk of ice severed Pine Island Glacier in the month of September of that year.
