Scientists Discover 'Lubricant' for Earth's Tectonic Plates: Hidden Magma Layer Could Play Role in Earthquakes
March 20, 2013 — Scientists have found a layer of liquefied molten rock in Earth's mantle that may be acting as a lubricant for the sliding motions of the planet's massive tectonic plates. The discovery may carry ... > full story -
Slabs of Ancient Tectonic Plate Still Lodged Under California
March 18, 2013 — The Isabella anomaly -- the seismic signal of a large mass of cool, dehydrated material about 100 kilometers beneath central California -- is in fact a surviving slab of the Farallon oceanic plate, ... > full story -
Oxygen-Poor 'Boring' Ocean Challenged Evolution of Early Life
March 18, 2013 — Biogeochemists have filled in a billion-year gap in our understanding of conditions in the early ocean during a critical time in life's history on Earth. During the period 1.8 to 0.8 billion years ... > full story -
Computer Models Show How Deep Carbon Could Return to Earth's Surface
March 18, 2013 — Computer simulations of water under extreme pressure are helping geochemists understand how carbon might be recycled from hundreds of miles below the Earth's ... > full story -
Earth's Interior Cycles Contribute to Long-Term Sea-Level and Climate Change, Researchers Find
March 18, 2013 — Ancient rises in sea levels and global warming are partially attributable to cyclical activity below Earth's surface, researchers have concluded in an analysis of geological studies. However, changes ... > full story -
Ocean Plankton Sponge Up Nearly Twice the Carbon Currently Assumed
March 17, 2013 — Models of carbon dioxide in the world's oceans need to be revised, according to new work. Trillions of plankton near the surface of warm waters are far more carbon-rich than has long been thought, ... > full story -
Highly Effective Communities of Bacteria in the World's Deepest Oceanic Trench
March 17, 2013 — Deep sea trenches act as hot spots for microbial activity, according to new ... > full story -
Life Deep Within Oceanic Crust Sustained by Energy from Interior of Earth
March 14, 2013 — The Earth's oceanic crust covers an enormous expanse, and is mostly buried beneath a thick layer of mud that cuts it off from the surface world. Scientists now document life deep within the oceanic ... > full story -
Extreme Water in Earth's Interior
March 13, 2013 — Earth is the only known planet that holds water in massive quantities and in all three of the main phase states. But the earthly, omnipresent compound water has very unusual properties that become ... > full story -
Earth Warmer Today Than During 70 to 80 Percent of the Past 11,300 Years
March 7, 2013 — Using data from 73 sites around the world, scientists have been able to reconstruct Earth's temperature history back to the end of the last Ice Age, revealing that the planet today is warmer than it ... > full story
