Researchers diving in a submersible in the eastern Pacific realized that the landscape they had studied the day before had been glassed over by fresh lava. By Maya Wei-Haas Maya Wei-Haas previously ...

The human-occupied vehicle Alvin, during a dive on the East Pacific Rise, collected samples and recovered instruments placed at the vents during previous expeditions. Woods Hole, Mass (October 13, ...

Gold concentrations in these magmas were several times higher than those found in comparable melts from mid-ocean ridges.

Volcanic glass recovered from the Kermadec Arc north of New Zealand contains gold concentrations several times higher than comparable magma from mid-ocean ridges. Chemical measurements show that the ...

For most of human history, the creation of new ocean floor has been something inferred rather than witnessed. Geologists could map ancient scars on the seabed, measure the slow movement of tectonic ...

A computer model shows how iron released by deep-sea hydrothermal vents could have spread through the Pacific Ocean during ice-age sea-level declines. Developed by a team led by Boston College ...
