Additional Listening 01 Scientists Aim to Explore Area of Life 1000 Meter Under the Sea Words in This Story thrive –v. to grow and develop successfully compartment –n. a separate area within a vehicle A team of scientists plans to explore a little-known part of the ocean to search for new sea life and to 1. the effects of pollution and climate change. The scientists will enter what they call the "Midnight Zone" of the Indian Ocean. It is an area at a 2. of about 1,000 meters below the surface where light does not reach but life still thrives. The project is expected to begin on March 16 and to last about five weeks. The scientists aim to explore huge underwater mountains also known as seamounts. The scientists involved in the project are part of Nekton, an ocean research group that works with the University of Oxford in Britain. They are working with the Seychelles' and Maldives' governments in an effort to protect ocean areas. Oliver Steeds is the director of the Nekton effort. He told the Associated Press that the area his team will explore is home to many forms of life. "What we do know is that 3. 1,000 meters, there's no light down there, but a lot of animals...are bioluminescent. It's life that glows," he said. Speaking to AP in Barcelona, Spain, Steed noted that this team was going into an 4. part of the ocean. A submarine unlike any other The Nekton scientists will be using one of the most modern deep sea submarines in the world. It is named Limiting Factor. Last August, the Limiting Factor completed another project: to dive to the deepest point in each of the world's five oceans. That effort was called the Five Deeps Expedition. The deepest of these dives took the submarine to nearly 11,000 meters below sea level. The Limiting Factor is built to 5. the huge pressure that exists in the ocean's deepest places. The compartment for the crew of two people is surrounded by titanium nine centimeters thick. The submarine also carries enough 6. oxygen for up to 96 hours. Robert McCallum is the leader of the expedition. He said vehicles that can dive deep into the ocean are rare. The scientists will use 7. and mapping technology to identify new 8. and landforms deep beneath the sea. But, they also want to 9. the effects humans have on the deep sea environment. They will be trying to measure the presence of plastic pollution and possible effects of climate change. Limiting Factor crew already have seen 10. that pollution is affecting places considered untouched. In May, they saw a plastic bag at the bottom of the Mariana Trench, the deepest point in the world's oceans. Dan Laffoley is a marine 11. for the International Union for Conservation of Nature, a group based in 12. . He said exploration of the Earth's living space is 13. important. He added, "...over 90 percent of that living space is in the ocean and most of that ocean is unexplored." Laffoley said it is 14. , during a time of change, "...that we get people down there, we get eyes in the ocean and we see what's happening." The Nekton scientists will 15. their observations with an earlier study of the deep Indian Ocean last year. They plan to present their findings in 2022.
