The other "oceans" are found under thick covers of surface ice. If both liquid and frozen water are counted, Earth ranks fifth in volume of its oceans. [2] Recent studies indicate a large underground saltwater ocean present on Ganymede, Jupiter’s largest moon, with estimated water volume eight times greater than Earth’s world ocean. [3]
The Challenger Deep is a relatively small slot-shaped depression in the bottom of a considerably larger crescent-shaped oceanic trench, which itself is an unusually deep feature in the ocean floor. The Challenger Deep consists of three basins, each 6 to 10 km (3.7 to 6.2 mi) long, 2 km (1.2 mi) wide, and over 10,850 m (35,597 ft) in depth ...
Sonar mapping of the Challenger Deep by the DSSV Pressure Drop employing a Kongsberg SIMRAD EM124 multibeam echosounder system (26 April–4 May 2019). Challenger Deep (CD) is the deepest known point in the Earth's seabed hydrosphere, a slot-shaped valley in the floor of Mariana Trench, with depths exceeding 10,900 meters. [1]
The hadal zone, also known as the hadopelagic zone, is the deepest region of the ocean, lying within oceanic trenches.The hadal zone ranges from around 6 to 11 km (3.7 to 6.8 mi; 20,000 to 36,000 ft) below sea level, and exists in long, narrow, topographic V-shaped depressions.
So far, there is no evidence that life exists on Europa, but the moon has emerged as one of the most likely locations in the Solar System for potential habitability. [140] [182] Life could exist in its under-ice ocean, perhaps in an environment similar to Earth's deep-ocean hydrothermal vents.
The Drake is part of the most voluminous ocean current in the world, with up to 5,300 million cubic feet flowing per second. Squeezed into the narrow passage, the current increases, traveling west ...
Enceladus is the sixth-largest moon of Saturn and the 18th-largest in the Solar System. ... The ocean may be 10 kilometers (6.2 mi) deep at the south pole. [26] [98]
The pit is located at 8.3355°N, 33.222°E on the moon's surface. Radar imaging indicated that the pit's funnel is roughly 20 meters deep, while the inner pit has a depth of approximately 105 meters. The diameter of the pit's funnel was between 140 and 146 meters long while the diameter of the inner pit is 88–100 meters long.
