About 70 % ofEarth ’s surface is covered in water , and researchers are hear to map every last inch of it . On June 21 ( that ’s World Hydrography Day , in case you forgot to revise your Calendar of Very Nerdy Events ) , a group of international researcher announced that they are about one - fifth of the direction to that goal , having mapped 20.6 % of Earth ’s full underwater area using modern sonar technique , accord to a instruction .
The project , holler Seabed 2030 , purport to map 100 % of the global sea floor by 2030 using largely crowd - sourced data from science vessels , corporations and private gravy boat possessor around the world . The current stratum of reporting shows a modest increment over last year ’s figure of 19 % ( research was hamper by COVID-19 , project theater director and hydrographer Jamie McMichael - Phillipstold the BBC ) , but the project has nevertheless seen huge gains since its inception four years ago .

" When Seabed 2030 was launched in 2017 , only 6 % of the ocean had been mapped to modern standard , " the squad write in the statement . In the last year , the team discharge another 1.6 % of the global ocean mathematical function , adding an area " more or less around half the size of it of the United States , " McMichael - Phillips added .
late reporting includes some of the most hard - to - reach places on Earth , thanks to data shared by billionaire explorer Victor Vescovo and the bunch of his ship , the DSSV Pressure Drop . In September 2019 , Vescovo complete a personal mission to descend to thedeepest points in all five of Earth ’s oceansaboard a small submersible warship . Vescovo ’s team also used bathymetric cat’s-paw aboard the Pressure Drop to map these bottom - of - the - world hot spot while the ship was in the neighborhood . The team ’s pleasure trip mapped an area tantamount to the size of France in more or less 10 calendar month , more than half of which had never been see before , the BBC reported .
Why map the integral ocean ? It ’s not to uncover thelost city of Atlantis(at least , not officially ) . According to the Seabed team , a comprehensive reason of the sea floor is crucial to various scientific and commercial pursuits . On the business side , unspoiled seafloor mathematical function can aid vessels pilot more efficiently , and they can also aid try like laying cable system and constructing pipelines , the squad said .
But more importantly , these function can let out previously unknown patterns in deep ocean currents , which are tempt by variation in the seafloor topography . Accurate information about currents can help oneself improveclimate changemodels , as the sea plays a central role in strike high temperature around Earth , the BBC reported .
With a dull 2020 behind them , the Seabed team is affirmative that the task will reach 100 % ocean level reporting by 2030 . For more project update , tune in again next yr on World Hydrography Day .
