Mapping Ocean Floor Latest Technique
The latest status of its seabed 2030 project was announced to coincide with world hydrography day.
Mapping ocean floor latest technique. As of june 2020 we have only mapped 20 of it and continue to discover major features including. The nippon foundation gebco seabed 2030 project has mapped one fifth of the world s ocean floor. Seafloor mapping also called seabed imaging is the measurement of water depth of a given body of water bathymetric measurements are conducted with various methods from sonar and lidar techniques to buoys and satellite altimetry various methods have advantages and disadvantages and the specific method used depends upon the scale of the area under study financial means desired measurement.
There are three tools used to map the ocean floor sonar satellites and submersibles. The first modern breakthrough in sea floor mapping came with the use of underwater sound projectors called sonar which was first used in world war i. It is the only intergovernmental organisation with a mandate to map the entire ocean floor.
In the search for the plane a large area of the indian ocean was mapped using high resolution multibeam echosounder that provided high detailed data of the ocean floor. The disappearance of flight mh370 in the indian ocean caused global headlines. By the 1920s the coast and geodetic survey an ancestor of the national oceanic and atmospheric administration s national ocean service was using sonar to map deep water.
The problem with that approach is that our oceans are vast and ships are small meaning only a tiny percentage of the ocean floor between 5 15 percent nasa estimates was mapped. On the occasion of world hydrography day the nippon foundation gebco seabed 2030 project which aims to facilitate the complete mapping of the global ocean floor by 2030 has announced the inclusion of 14 5 million square kilometres of new bathymetric data in the latest gebco grid. Despite making up the majority of our planet s surface the ocean floor is still a mystery.
Mapping the complex seafloor. Sonar is a type of electronic depth sounding equiptment made in the 1920 s it is an acronym. Mapping the ocean floor ocean floor features tools used to map the ocean floor today s technology lets scientists to study the ocean in a quicker and precise way.
