The seafloor has been studied by scientists using echo-sounding technology since the early 20th century; significant advances were made during and after World War II, but these early techniques ...

Above: A marine gravity map of the North Atlantic Ocean Red dots show locations of earthquakes with magnitude > 5.5 and they highlight the present-day location of the seafloor spreading ridges and ...

The spreading of the seafloor has slowed, and scientists aren’t sure why. The slowdown could mean a drop in greenhouse emissions from volcanoes, which are affected by the seafloor-creating process.

It confirmed sea-floor spreading as hypothesized by Hess, and thus "continental drift," originally proposed by Alfred Wegener back in 1912. It convinced many that plate tectonics was the best ...

There seems to have been a lapse in the crustal spreading of the sea floor from the Mid-Atlantic Ridge during the late Tertiary period. Nature - Discontinuities in the History of Sea-floor Spreading.

Alexandria, VA - As the U.S. celebrates National Oceans Month in June, scientists who study the seafloor are excited because they believe that humans will end this century with a far better view ...
