Mariana Trench: Deepest-ever sub dive finds plastic bag
The latest dive reached 10,927m (35,849ft) beneath the waves making a new record.
An American explorer has found plastic waste on the seafloor while breaking the record for the deepest ever dive. Victor Vescovo descended nearly 11km to the deepest place in the ocean – the Pacific Ocean’s Mariana Trench.
He spent four hours exploring the bottom of the trench in his submersible, built to withstand the immense pressure of the deep. He found sea creatures, but also found a plastic bag and sweet wrappers. It is the third time humans have reached the ocean’s extreme depths.
The first dive to the bottom of the Mariana Trench took place in 1960 by US Navy lieutenant Don Walsh and Swiss engineer Jacques Piccard in a vessel called the bathyscaphe Trieste. Movie director James Cameron then made a solo plunge half a century later in 2012 in his bright green sub.
The latest descent, which reached 10,927m (35,849ft) beneath the waves, is now the deepest by 11m – making Victor Vescovo the new record holder. In total, Mr Vescovo and his team made five dives to the bottom of the trench during the expedition. Robotic landers were also deployed to explore the remote terrain.
Vescovo said: “It is almost indescribable how excited all of us are about achieving what we just did. “This submarine and its mother ship, along with its extraordinarily talented expedition team, took marine technology to a ridiculously higher new level by diving – rapidly and repeatedly – into the deepest, harshest, area of the ocean.”
