The Arctic Ocean is the smallest and shallowest of the world's five oceanic divisions. [ 1 ] It spans an area of approximately 14,060,000 km 2 (5,430,000 sq mi) and is the coldest of the world's oceans. The International Hydrographic Organization (IHO) recognizes it as an ocean, although some oceanographers call it the Arctic Mediterranean Sea ...
5,550 m (18,210 ft) Water volume. 600 km 3 (140 cu mi) The Molloy Deep (also known as the Molloy Hole) is a bathymetric feature in the Fram Strait, within the Greenland Sea [1] east of Greenland and about 160 km (100 mi) west of Svalbard. It is the location of the deepest point in the Arctic Ocean.
With a few exceptions, the shelf break is located at a remarkably uniform depth of roughly 140 m (460 ft); this is likely a hallmark of past ice ages, when sea level was lower than it is now. [ 11 ] The continental slope is much steeper than the shelf; the average angle is 3°, but it can be as low as 1° or as high as 10°.
GEBCO is the only intergovernmental body with a mandate to map the whole ocean floor. At the beginning of the project, only 6 per cent of the world's ocean bottom had been surveyed to today's standards; as of June 2022, the project had recorded 23.4 per cent mapped. About 14,500,000 square kilometres (5,600,000 sq mi) of new bathymetric data ...
Litke Deep (Russian: Жёлоб Ли́тке) is [1][2] an oceanic trench in the Arctic Ocean. The deepest point, also referred to as Litke Deep, is 5,449 m (17,877 ft) below sea level. It is the closest point of the upper surface of Earth's lithosphere to Earth's center, with Challenger Deep being 14.7268 km (9.2 mi) further from Earth's ...
On 23 May 2016, the Chinese submersible Haidou-1 dived to a depth of 10,767 m (35,325 ft) at an undisclosed position in the Mariana Trench, making China the third country after Japan (ROV Kaikō), and the US (HROV Nereus), to deploy a full-ocean-depth ROV. This autonomous and remotely operated vehicle has a design depth of 11,000 m (36,089 ft).
The Mariana Trench is an oceanic trench located in the western Pacific Ocean, about 200 kilometres (124 mi) east of the Mariana Islands; it is the deepest oceanic trench on Earth. It is crescent-shaped and measures about 2,550 km (1,580 mi) in length and 69 km (43 mi) in width. The maximum known depth is 10,984 ± 25 metres (36,037 ± 82 ft ...
The Greenland ice sheet is an ice sheet which forms the second largest body of ice in the world. It is an average of 1.67 km (1.0 mi) thick, and over 3 km (1.9 mi) thick at its maximum. [2] It is almost 2,900 kilometres (1,800 mi) long in a north–south direction, with a maximum width of 1,100 kilometres (680 mi) at a latitude of 77°N, near ...
