Terrible discovery – the “Frozen” balloon is eleven kilometers deep!

It is the lowest point on earth – and we even garbage it!

Only a few researchers managed to get to the deepest point in the Mariana Trench (east of the Philippines). The last was Victor Vescovo, who in April 2019 reached a depth of 10.9 kilometers in a special submarine.

▶︎ At a depth of eleven kilometers, the maximum depth of the Mariana Trench and thus the deepest part of the Pacific Ocean and all of the world’s oceans, scientists used a diving robot to find a helium balloon with characters from the Disney film “Frozen”. During his 2019 dive, Vescovo found unknown types of cancer, among other things – and plastic waste: a plastic cover for a lollipop and a plastic bag.

“We have always felt that there is a part of the planet beyond, untouched by human activity,” said Eric Galbraith, ocean biochemist at the Catalan Institution for Research and Advanced Studies in Barcelona and Associate Professor at McGill University in Montreal, Maclean’s magazine. “That used to be true. And now it is no longer true. “

This balloon, which shows characters from the 2013 film, proves how quickly garbage can sink in the sea. Next to him is a large plastic bucket.

In 2018, researchers from the Institute of Deep Sea Science and Engineering in China took water and sediment samples at depths between 2.5 and eleven kilometers. “Man-made plastics have contaminated the remotest and deepest places on the planet,” they wrote Messages according to an analysis published in the journal Geochemical Perspectives Letters.

“The (deepest Mariana) zone is probably one of the largest sinks for microplastic waste on earth, with unknown but potentially harmful effects on this fragile ecosystem.”
