Did you know the longest mountain range was discovered completely underwater? (Source #1) Technology has helped explorers overcome challenges during deep-sea explorations. The Aqualung, Jim Suit, and Deepsea Challenger are all used for ocean exploration. One example of technology is the Aqualung which was one of the first inventions for underwater exploration. It was invented by Jacques Cousteau in the 1940’s. (Source #2). Divers used the metal tank which had tubes attached for to breathe oxygen. (Source #2) Later on it was improved and it was renamed SCUBA Self Contained Underwater Breathing Apparatus. (Source #2) Another example was the Jim Suit. It can be worn by divers underwater. It is based on an astronaut space suit which has built in oxygen. (Source #2) With this technology they could now go farther than they ever could be. For example, Sylvia Earle went on a record-breaking dive in 1979 and she went down 1,250 feet for 2 ½ hours. ( Source #2). In the article it said, “Even the most experienced scuba divers can only go down 130 feet for 10 minutes.” The Jim Suit provides protections from the deadly pressure divers would experience. (Source #2) Lastly, the Deepsea Challenger was the most advanced technology invented by filmmaker James Cameron. (Source #2) This invention is a one-person submarine which has lights, 3D cameras, and a scooper arm to collect samples. (Source #2,3) Another example of its design includes thrusters on top, it can move vertically, and because it has a lightweight foam structure, it means it can float up to the surface faster. (Source #3). Because it is so advanced, it traveled down to the deepest part of the ocean, the Mariana Trench. (Source #2,3) Since explorers have only discovered 5% of the Earth’s oceans, we should try to explore more with technology.
