In July 2017 , a gargantuanicebergspanning five times the area of New York ’s five borough snapped off the sea-coast ofAntarcticaand start to drift northward .
Though its edges have break down considerably since then , the iceberg — named A-68a — is still thelargest on Earth , and it ’s currently barreling toward an island wildlife recourse in the South Atlantic Ocean . New aerial footage taken by the United Kingdom ’s Royal Air Force ( RAF ) disclose just what that island might be up against .
The Royal Air Force (RAF) photographed the world’s largest iceberg, which is on a collision course with South Georgia island.
For starting motor , the RAF footage really drives home how monumental this frappe giant is . ( As of early April , A-68a measured about 2,000 square miles , or 5,100 straight km , in domain , Live Science previously reported ) . The berg ’s steep walls hulk 100 foot ( 30 meters ) above the sea , according to RAF News , and are gouge with tunnel , crack and caves . Brobdingnagian chunks of frappe , or " growler , " are rapidly crack off on all side of meat , leaving behind a lead of debris that could impede boat dealings in the futurity . ( The waters are occasionally used by both fishery vehicles and pleasure cruises , accord to the BBC ) .

Of greater vexation to scientists , however , is how inscrutable the iceberg ’s keel dips below the ocean ’s control surface . When A-68a broke away from the Larsen C Ice Shelf three years ago , its bottom - most point was measured at more than 650 feet ( 200 grand ) below the surface , BBC write . It ’s potential that the berg has funk vertically as well as horizontally since then , though the RAF mission did n’t at once reveal any insights there .

The iceberg ’s depth matters as the behemoth bears down on South Georgia island – a British overseas territory that ’s abode to millions ofpenguins , seal , seafowl and migrate whale . If A-68a becomes grounded on the seafloor near South Georgia ’s coast , it could make a deadly impedimenta between the animals and their usual feeding evidence .

" The factual aloofness [ the animate being ] have to travel to find food for thought ( fish and krill ) really matters , " Geraint Tarling , an ecologist with the British Antarctic Society , said in a statement . " If they have to do a big detour , it means they ’re not going to get back to their unseasoned in sentence to prevent them starving to death in the meanwhile . "
It ’s still possible that A-68a will float harmlessly around South Georgia ’s coast before drifting further due north — however , the RAF said , it still looks to be on class for a unmediated strike . The berg is about 90 miles ( 150 kilometer ) away from the island , and could make landfall by the end of December , the BBC said .
