MOUNT EVEREST IS THE HIGHEST MOUNTAIN PEAK ON LAND AND MANY PEOPLE HAVE SCALED THAT PEAK QUITE EASILY. NOW WHEN WE COME TO THE SEAS THE DEEPEST PART IS THE MARIANA TRENCH IN THE PACIFIC OCEAN WHICH IS 10,920 METRES BELOW SEA LEVEL AND IF COMPARED TO MOUNT EVEREST IT WOULD ME APPROXIMATELY 2000 METRES MORE TO CLIMB. THIS WAS ONE OF THE WORLD'S LEAST KNOWN AND EXPLORED PLACE ON EARTH. SOMEDAY AN EXPEDITION HAD TO TAKE PLACE.
THAT DAY HAD OCCURRED. JAMES CAMERON THE HOLLYWOOD DIRECTOR OF FAMOUS MOVIES TITANIC AND AVATAR TOOK THIS CHALLENGE TO GO TO THE DEEPEST PART IN SEA AND EXPLORE IT. HE IS ALSO GOING TO DOCUMENT THAT EXPEDITION BASED ON THE REPORTS HE TOOK OF THE SAMPLES. THIS IS WAHT JAMES CAMERON SAID ABOUT THE EXPEDITION:
“I’ve always dreamed of diving to the deepest place in the oceans. For me it went from a boyhood fantasy to a real quest, like climbing Everest, as I learned more about deep-ocean exploration and became an explorer myself in real life. This quest was not driven by the need to set records, but by the same force that drives all science and exploration … curiosity. So little is known about these deep places that I knew I would see things no human has ever seen. There is currently no submersible on Earth capable of diving to the ‘full ocean depth’ of 36,000 feet. The only way to make my dream a reality was to build a new vehicle unlike any in current existence. Our success during seven prior expeditions building and operating our own deep-ocean vehicles, cameras, and lighting systems gave me confidence that such a vehicle could be built, and not just with the vast resources of government programs, but also with a small entrepreneurial team. It took more than seven years to design and build the vehicle, and it is still a work in progress. Every dive teaches us more, and we are continuing to improve the sub and its systems daily, as we move through our sea trials.” —James Cameron
THE EXPEDITION:
For this expedition, Cameron squeezed into a pilot sphere so small he was note able to extend his arms. He was the sole occupant in a complex, 24-foot-long (7.3-meter-long) craft made primarily of highly specialized glass foam. As he maneuvered on the ocean floor amid unexplored terrain and strange new animals, Cameron filmind a feature-length documentary and collect samples for historic research. Why? To promote exploration and scientific discovery.
The dive was part of the DEEPSEA CHALLENGE expedition, a partnership with National Geographic that took Cameron, along with fellow pilot Ron Allum and a team of engineers, scientists, educators, and journalists, to the greatest depths of the ocean—places where sunlight doesn’t penetrate and pressure can be a thousand times what we experience on land. After years of preparation, the team headed to the Mariana Trench, a 1,500-mile-long (2,400-kilometer-long) scar at the bottom of the western Pacific Ocean. There, about 200 miles (320 kilometers) from Guam, Cameron continued the work that Don Walsh and Jacques Piccard, the first men to dive the trench in the bathyscaphe Trieste, started in 1960. While the Trieste was not equipped to take pictures or get samples, Cameron and his DEEPSEA CHALLENGER submersible were armed with multiple cameras and a mechanical arm for scooping up rocks and animals. These samples could enable groundbreaking discoveries: Studying the forces that shape these trenches could help us to better understand the earthquakes that cause devastating tsunamis; studying the fauna that survives there could lead to breakthroughs in biotechnology and our understanding of how life began.For Cameron, who explored the Titanic wreck during his production of the Academy Award-winning film, reaching the deepest point on Earth has been a long-term goal. “Imagination feeds exploration,” he said. “You have to imagine the possible before you can go and do it.”
THE TIME TAKEN BY CAMERON FOR DIVING IN WAS 2HRS AND 36 MINUTES AND WHILE COMING IT WAS MUCH FASTER HE TOOK ONLY 70 MINUTES. HE TOOK ALL THE SAMPLES FOR A PERIOD OF 3 HRS INSTEAD OF 6 HRS WHICH WAS ACTUALLY PLANNED.
DEEP SEA CHALLENGER:
Deepsea Challenger (DCV 1) is a 7.3-metre (24 ft) deep-diving submersible designed to reach the bottom of Challenger Deep, the deepest known point on Earth. On March 26, 2012, Canadian film director James Cameron piloted the craft to accomplish this goal, becoming the first person to reach Challenger Deep in a one-man craft. Built in Sydney, Australia by the research and design company Acheron Project Pty Ltd, the Deepsea Challenger includes scientific sampling equipment and high-definition 3-D cameras, and reached the ocean's deepest point after roughly two hours of descent from the surface
