Just 12 sidereal day later , they arrived to chance a never - before - seen ecosystem filled with giant sponges , fish , enormous ocean spider and octopuses discover to the open tune for the first fourth dimension .
" We seize upon the moment , changed our expedition plan , and function for it so we could look at what was happening in the deepness below , " expedition co - chief scientistPatricia Esquete , a marine life scientist at the University of Aveiro in Portugal , say in a argument . " We did n’t expect to discover such a beautiful , thriving ecosystem . free-base on the size of the animals , the communities we observed have been there for decades , maybe even one C of years . "
What lies beneath Antarctica ’s roughly 500 feet ( 150 meter ) of ice is scarcely known , but scientists have distrust that it is filled with a mammoth web of rivers , lakes and estuaries . Yet it was n’t untilvery recentlythat scientists unwrap that this hidden underworld harbor life .

Once there , the submarine collected biological and geologic samples from among the region ’s coral and ocean sponges . Some of these creature ' tremendous sizes suggested they ’d been grow for 100 . The research worker also deployed other autonomous vehicles to canvas how meltwater is affect the region .
" The skill team was originally in this remote realm to study the seafloor and ecosystem at the port between ice and sea,“Jyotika Virmani , executive director of the Schmidt Ocean Institute , said in the assertion . " Being right there when this iceberg calved from the ice ledge presented a rare scientific opportunity . Serendipitous moments are part of the excitation of research at ocean — they provide the fortune to be the first to find the untouched beauty of our world . "
