Bush signed the act naming the trench as a National Monument in 2009. The megalodon was a 20-ton beast who could take down a T-Rex with ease. In the book, the hero of the story, Jonas Taylor, is exploring the trench when he comes across a supposedly long-extinct predator, the Carcharodon megalodon. One such tale was the book, “Meg,” by New York Times bestselling author Steve Alten. This crescent-shaped scar on the earths crust is 2,550 kilometers long and 69 kilometers wide on average, and at Challenger Deep, it is 10.91 kilometers in depth. The trench’s mystery and allure has spawned some fictional accounts of what could be going on down there. The Puerto Rico Trench is located on the boundary between the Caribbean Sea and the Atlantic Ocean.The oceanic trench, the deepest in the Atlantic, is associated with a complex transition between the Lesser Antilles subduction zone to the south and the major transform fault zone or plate boundary, which extends west between Cuba and Hispaniola through the Cayman Trough to the coast of Central. Located in Western Pacific Ocean the Mariana Trench is the deepest section of the earths surface and also has the earths deepest point, the Challenger Deep. His trip was the first manned expedition to the trench since 1960. To reach his goal, Cameron had a 24-foot submersible designed that had a window which was 9 and a half inches thick to withstand the enormous pressure of the deep. Depths >3000 m account for 75.3 of the worlds oceans, an area covering 230,910,385 km2, of which 85 of it is uncharted (equal to 69 of the entire ocean. While there, he took pictures – the first snapshots ever in the Challenger Deep. James Cameron, the famed director, manned an expedition to the bottom of the Mariana Trench in 2012. The HMS Challenger II sounded the trench 76 years after the HMS Challenger first did in 1875. It was named for two ships that have explored its depths with sounding equipment – the HMS Challenger and the HMS Challenger II. Some points of the trench are deeper than others, with the deepest section being called the Challenger Deep. During the trip, about 4,700 species were discovered. During that time the ship went almost 70,000 nautical miles, exploring and mapping as it traveled. This undertaking – the Challenger expedition from 1872 to 1876 – was revolutionary in the field of oceanography. It was named for the nearby Mariana Islands. ![]() It was found by utilizing sounding equipment on the HMS Challenger. The Mariana Trench was first pinpointed in 1875 during the undertaking of a global circumnavigation. A new type of snailfish was found in the trench. There are more than 200 known microorganisms and small creatures that live there, including crustaceans and amphipods.Īs more expeditions eventually explore the trench, it’s almost certain new species will be discovered there. The green shape, a small crustacean, is seen in the snailfish’s stomach.Adam Summers/University of Washingtonĭespite the lack of light and the hostile, acidic conditions in the trench, a surprising number of organisms live there.
