The seabed (also known as the seafloor, sea floor, ocean floor, and ocean bottom) is the bottom of the ocean. All floors of the ocean are known as 'seabeds'. The structure of the seabed of the global ocean is governed by plate tectonics. Most of the ocean is very deep, where the seabed is known as the abyssal plain. Seafloor spreading creates ...
The Atlantis Massif is a prominent undersea massif in the North Atlantic Ocean.It is a dome-shaped region approximately 10 miles (16 km) across and rising about 14,000 feet (4,267 m) from the sea floor.
The sculpture park, which began construction in 2006, [1] is situated on the sandy ocean floor in the barren Molinere Bay. The sculpture park now helps relieve tourist pressure on natural reefs. The sculpture park now helps relieve tourist pressure on natural reefs.

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 ...
The elevated ocean floor is known as the Hawaiian Arch. The Hawaiian Arch extends about 656 feet (200 meters) above the surrounding ocean floor, and contains tilted coral reefs . [ 3 ] The Hawaiian Trough is about 18,045 feet (5,500 meters) deep and has a radius of about 8.7 miles (14.0 km).
On the bottom of the body was a downward-facing sonar system to monitor the sled's height above the ocean floor. [1] It was capable of working in depths up to 20,000 feet (6,100 m) [ 3 ] and could therefore reach roughly 98% of the sea floor. [ 1 ]
Magnetic anomalies off west coast of North America. Dashed lines are spreading centers on mid-ocean ridges. The Vine–Matthews-Morley hypothesis correlates the symmetric magnetic patterns seen on the seafloor with geomagnetic field reversals. At mid-ocean ridges, new crust is created by the injection, extrusion, and solidification of magma.
