Scientists have developed a new ocean map that shows previously unknown mountains, ridges and trenches underneath the world’s oceans. One of their discoveries includes a massive ridge that’s as wide as Texas and located underneath the Gulf of Mexico.
Details on the study that led to the new ocean map were published in the journal Science, report The Guardian and other major media outlets. Researchers said they used data from NASA’s Jason-1 and the European Space Agency’s CryoSat-2 satellites.
The data revealed thousands of underwater mounts in some of the globe’s most remote parts of the oceans. This is the first time scientists have been able to put together such a detailed ocean map.
According to researchers, approximately 71% of the surface of the globe is covered by water and survey ships haven’t charted about 90% of the oceans’ floor yet. Survey ships use acoustic beams to collect map data for the ocean floor.
Scientists said that they actually know more about Mars’ topography than about the floors of our own oceans. They added that the Malaysia Airlines flight MH370 demonstrated just how little we know about the topography under the oceans.
