The Mariana Trench is not only the deepest oceanic trench on Earth but also holds the two lowest points on the planet. This crescent- shaped trench is located in the Western Pacific, east of the Mariana Islands near Guam. The region around the trench is known for many unique environments, such as vents bubbling up liquid sulfur and carbon dioxide, active mud volcanoes, and marine life adapted to pressures 1,000 times more than at sea level.
The Challenger Deep, the southern end of the Mariana Trench, is the deepest spot in the ocean. The National Oceanic and Atmospheric Administration, in 2010, used sound pulses sent through the ocean and calculated the Challenger Deep to be 10,994 metres deep even though it was considered almost impossible to measure its depth. In 2021, pressure sensors were used to calculate its depth and it was discovered that the deepest spot in Challenger Deep was 10,935 m. The ocean’s second-deepest place is also in the Mariana Trench. The Sirena Deep, which lies 200 kilometres to the east of Challenger Deep, is 10,809 metres deep.
