A former NASA employee has released a fascinating animation which shows how the look of the planet would change if all the oceans—which cover three fifths of the surface—gradually drained away.

A newly developed method that detects tiny bits of zircon in rock reliably predicts the age of ocean crust more than 99 percent of the time, making the technique the most accurate so far. After ...

The earthquake distribution on ultra-slow mid-ocean ridges differs fundamentally from other spreading zones. Water circulating at a depth of up to 15 kilometers leads to the formation of rock that ...

Ken Sims, a professor in UW’s Department of Geology and Geophysics, recently received a $325,841 National Science Foundation grant to look at understanding the processes and timescales of basalt ...

Sometimes in science, even a successful prediction isn’t enough. Earlier this year, we covered some research suggesting that ice age fluctuations in sea level influenced the volcanism at mid-ocean ...

Oceanography, Vol. 20, No. 1, SPECIAL ISSUE ON InterRidge (MARCH 2007), pp. 128-137 (10 pages) Baker, E.T., German, C.R., and H. Elderfield. 1995b. Hydrothermal ...

Generally speaking, "ridge subduction" involves subduction of spreading oceanic ridges, aseismic ridges or oceanic plateaus and inactive arc ridges, and this common and important geological process ...

Scientists from the Woods Hole Oceanographic Institution (WHOI) have identified a new type of ocean ridge that is spreading so slowly that Earth's mantle is exposed over large regions of the sea floor ...

ABSTRACTAs part of the suite of multidisciplinary investigations undertaken by the Ridge 2000 Program, new multichannel seismic studies of crustal structure were conducted at the East Pacific Rise ...
