Sea-Floor Spreading Geophysical phenomena ranging from earthquakes to continental drift are being explained by a new theory that gives promise of eventually relating geomagnetism and the earth's ...

Photo: Harry Hess argues that the continents had once been one, and have drifted apart. With the discovery of plate tectonics and the mapping of the earth into about 12 plates, plus the ...

“Tharp’s work certainly provided evidence and weight to the theory of plate tectonics, but her work is really about seafloor ...

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 ...

Such spooktacular stories may soon be put to rest. In 2019, the U.S. began a seafloor mapping initiative that included the Great Lakes. The project should be able to take note of sunken vessels or ...

Scientists have now identified a strange slice of Earth deep below the Pacific that may explain why this region is currently creating the world's fastest spreading ocean ridge – the East Pacific ...

Boaties heading out on the water this summer are urged to take extra care to prevent the spread of exotic caulerpa. The highly invasive marine pest threatens to wreak havoc on our marine ecosystems ...
