A Stiff New Layer in Earth's Mantle

By crushing minerals between diamonds, a University of Utah study suggests the existence of an unknown layer inside Earth: part of the lower mantle where the rock gets three times stiffer. The discovery may explain a mystery: why slabs of Earth’s sinking tectonic plates sometimes stall and thicken 930 miles underground.

URI Grad Student Investigates Unexplored Underwater Volcano Off Solomon Islands

URI doctoral student Brennan Phillips is on the hunt for underwater volcanoes so he can collect data on the plumes of hot fluids and chemical compounds emanating from hydrothermal vents in and around the craters. His latest adventure took him to the unexplored Kavachi volcano off the Solomon Islands.

Media Tip Sheet: URI Research to Be Presented at International Earth Science Meeting, Dec. 15-19

Research on underwater volcanoes, Great Lakes pollution, subseafloor life and much more will be among the 40 projects that will be presented by scientists from the University of Rhode Island’s Graduate School of Oceanography at the American Geophysical Union’s fall meeting in San Francisco from Dec. 15 to 19.

UW Team Explores Large, Restless Volcanic Field in Chile

For seven years, an area larger than the city of Madison has been rising by 10 inches per year. That rapid rise provides a major scientific opportunity: to explore a mega-volcano before it erupts. That effort, and the hazard posed by the restless magma reservoir beneath Laguna del Maule, are described in a major research article in the December issue of GSA Today.

How Water Could Have Flowed on Mars

The surface of Mars clearly shows what looks like evidence of flowing water: riverbeds, deltas, and the like. But these signs have been a puzzle – until now. The Weizmann Institute’s Dr. Itay Halevy and Brown University’s Dr. James Head III have identified a possible source: violent eruptions from massive volcanoes that periodically melted Mars’ ice.

By measuring how fast Earth conducts electricity and seismic waves, a University of Utah researcher and colleagues made a detailed picture of Mount Rainier’s deep volcanic plumbing and partly molten rock that will erupt again someday.

Volcano Discovered Smoldering Under a Kilometer of Ice in West Antarctica

sidley.jpeg

A temporary seismic array in Marie Byrd Land in West Antarctica recorded two bursts of activity in 2010 and 2011. Careful analysis of the events shows they originate from a subglacial volcano at the leading end of a volcanic mountain chain. The volcano is unlikely to erupt through the kilometer of ice that covers it but it will melt enough ice to change the way the ice in its vicinity flows.
