To collect a sounding, scientists use sonar devices to emit a sound wave that passes into the water. Since 2004, the Nippon Foundation/GEBCO Training Program has trained students from around the world in seafloor mapping through a one-year postgraduate course held at the University of New Hampshire, USA. The ocean floor is largely unexplored - ship based measurements, such as sonar, have mapped a small percentage of the open ocean. Download IBCSO V1.0 DBM 2. The International Bathymetric Chart of the Arctic Ocean (IBCAO) initiative developed a digital database that contains all available bathymetric data north of 64 degrees North. The data on the map can be interpreted to find seamount locations, convergent boundaries and slow/fast spreading ridges (divergent boundaries) and other features of varying elevation. If there is a steep ascent of the ocean floor near the beach, it will cause waves to rise more quickly, and become bigger. 30 MB - GeoTIFF, 10800 x 10800 The ocean covers 71% of the Earth's surface, has an area of 139,400,000 square miles and an average depth of 2.3 miles.
