“We had this magic key, this magic magnetic profile,” Pitman said. “We were able to date it and eventually use it not only as a tool that proved continental drift but a tool by which we could actually reconstruct the pattern of drift, that is the relative position of the continents, and the actual timing of the separation of the continents.”

The bottom of the ocean just keeps getting better. Or at least more interesting to look at.
Aboard a ship at the Mid-Atlantic Ridge, scientists are studying how the deepest and coldest waters mix with shallower waters, gaining heat in the process.
A new study in Science questions the provocative idea that climate change may shape the texture of the sea floor. A Snickers bar helps explain what’s really going on.
New pictures in the journal Nature Geoscience may help resolve a debate about how new crust forms at mid-ocean ridges where earth’s tectonic plates are slowly pulling apart.
Can shifting tides trigger earthquakes? Research done by Maya Tolstoy, a geophysicist at Lamont-Doherty Earth Observatory, suggests they do.
