Comment on “Glacial cycles drive variations in the production of oceanic crust”
by John Goff Abstract: Crowley et al. (Reports, 13 March 2015, p. 1237) propose that abyssal hill topography can be generated by variations in volcanism at mid-ocean ridges modulated by Milankovitch cycle–driven changes in sea level. Published values for...

LiveScience: Waking Beasts: Underwater Volcanoes Roused by Ice Ages
"In a broad sense, this reinforces the idea that the climate system and the solid Earth are connected and, in fact, may be thought of as a single system," Katz said. "Not only do ice ages affect volcanism, but volcanism has a feedback effect on climate...
Science Mag News: Record grooves on ocean floor document Earth’s ice ages
As the pressure on the ocean floor eases, magma erupts more readily at the spreading centers, thickening the plates and creating the abyssal hills, say the authors of two new studies, one published online this week in Science (scim.ag/JCrowley)...( more)
Nature: Ice ages made Earth's ocean crust thicker
“We know that volcanism has an effect on climate. What we’re seeing is that climate cycles are also affecting ocean volcanism,” says Richard Katz, a geophysicist at the University of Oxford, UK, and one of the authors of the study, which is reported today...

Lamont Photo Essay: Fire and Ice Off Cascadia
Ice ages come and go. So do pulses of volcanic eruptions on land and at sea, maybe, on roughly the same time scale. Could the two be related? A recent two-week oceanographic expedition aimed to find out...( more)
