This is the text (if you need help).
Ocean explorers filmed the world's deepest known shipwreck for the first time. The World War II battleship, the USS Johnston, was sunk by the Japanese Navy in 1944. The shipwreck is now on the ocean floor, around 6,456 metres deep. The film crew went down to that incredible depth and darkness in a submersible that can deal with the pressure of the deep ocean. The filming took place during two eight-hour dives.
The lead explorer, Victor Vescovo, was in the US Navy and is an adventurer. He has visited hard-to-get-to places. He is the first person ever to get to the top of all the world's continents, both poles, and the bottom of all the world's oceans. His mission to film the USS Johnston was a personal one. He said: "As a US Navy officer, I'm proud to have helped bring clarity and closure to the USS Johnston."
