Scientists plan to test whether the substance, specimens of which they collected, of microplastics.
American researchers found plastic debris on the ocean floor while setting the record for the deepest dive.
He spent four hours exploring the bottom of the basin. The researcher discovered sea creatures, and also found a plastic bag and candy wrappers. This is the third time the man was able to achieve the greatest depths of the ocean.
The first dive to the bottom of the Mariana trench was carried out in 1960, US Navy Lieutenant don Walsh and Swiss engineer Jacques Piccard in an apparatus called a bathyscaphe “Trieste”. Half a century later, in 2012 Director James Cameron made a solo dive in the submersible.
Last dive reached a depth of 10 927 metres by 11 metres deeper than the previous record. Thus Victor Vescovo became the new champion.
During the expedition were discovered traces of human activity on the planet – plastic waste. Previously, other expedition had ever seen.
Annually in the oceans are millions of tons of plastic, but about where he is in the end, it turns out, is little known.
According to the team, they also managed to open four new species of crustaceans, called amphipods, or amphipods. Members of the expedition said they saw a ringed worm like echiurida at a depth of 7,000 meters and a pink sea slug at a depth of 8000 meters.
Now scientists plan to test whether the substance, specimens of which they collected, of microplastics. Recent studies have shown that this is a common problem even for animals living at depth.
