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 ...
False color map of ocean depth in the Atlantic basin. The bathymetry of the Atlantic is dominated by a submarine mountain range called the Mid-Atlantic Ridge (MAR). It runs from 87°N or 300 km (190 mi) south of the North Pole to the subantarctic Bouvet Island at 54°S. [24]
A bathymetric chart is a type of isarithmic map that depicts the submerged bathymetry and physiographic features of ocean and sea bottoms. [1] Their primary purpose is to provide detailed depth contours of ocean topography as well as provide the size, shape and distribution of underwater features.
Continental shelves appear mostly by a depth of 140 meters, mid-ocean ridges by 3000 meters, and oceanic trenches at depths beyond 6000 meters. A seafloor map captured by NASA Bathymetry ( / b ə ˈ θ ɪ m ə t r i / ; from Ancient Greek βαθύς ( bathús ) 'deep' and μέτρον ( métron ) 'measure') [ 1 ] [ 2 ] is the study of ...
The sea floor below the break is the continental slope. [4] ... The depth of the shelf also varies, ... North Atlantic Ocean 28 ± 1.08 259 115.7 ± 1.6 434
Major fractures zones of the Atlantic can be seen on this ocean depth map Active Atlantic Ocean fracture zones are perpendicular to the mid-ocean ridges (black lines) in orange shaded region In the Atlantic Ocean most fracture zones originate from the Mid-Atlantic Ridge , which runs from north to south, and are therefore west to east oriented ...
Maps exhibiting the world's oceanic waters. A continuous body of water encircling Earth, the World/Global Ocean is divided into a number of principal areas. Five oceanic divisions are usually recognized: Pacific, Atlantic, Indian, Arctic, and Southern/Antarctic; the last two listed are sometimes consolidated into the first three.
Nautical charts must be labeled with navigational and depth information. There are a few commercial software packages that do automatic label placement for any kind of map or chart. Modern systems render electronic charts consistent with the IHO S-52 specification, issued by the International Hydrographic Organization (IHO).
