This VOICE project is a direct response to the Frontiers initiative and would not have been conceived without the opportunities offered by NSF FESD (Frontiers in Earth-System Dynamics) program requirements. FESD is focused on the fact that we are just beginning to understand how Earth operates as a system, and that many important scientific questions lie at the intersection of traditional disciplines of Earth, ocean and atmospheric sciences. The aim of the program is to "explore the coupling among different aspects of the Earth's component systems." These aims conform with our objectives, which has at its core the coupling between Earth’s interior, ocean and atmosphere, and is focused on understanding glacial cycles as an Earth system process that includes relationships with Earth’s interior. (See here to learn more about NSF FESD.) Furthermore, the samples collected throughout the life of this project will be an invaluable resource for measurements beyond our program, and to address other scientific problems that lie outside the scope of this proposal. Hence, our collected data and samples will be made available to others via this website, which is devoted to volcano/climate connections on glacial/interglacial time scales.

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 abyssal hill characteristic widths versus spreading rate do not generally support this hypothesis. I argue that abyssal hills are primarily fault-generated rather than volcanically generated features. Full Text (PDF)

"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 itself. We haven't proved that yet, but it's a tantalizing possibility."...(more)

“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 in Science...(more)
