 | The vast Tibetan Plateau--the world's highest and largest plateau, bordered by the world's highest mountains--has long challenged geologists trying to understand how and when the region rose to such spectacular heights. New evidence from an eight-year study by U.S. and Chinese researchers indicates that the plateau rose in stages, with uplift occurring first in the central plateau and later in regions to the north and south. ...> Full Article |
 | Major floods striking America's heartland in March offer a preview of the spring seasonal outlook, according to NOAA's National Weather Service. Several factors will contribute to above-average flood conditions, including record rainfall in some states and snow packs, which are melting and causing rivers and streams to crest over their banks. The week of March 15, more than 250 communities in a dozen states are experiencing flood conditions. ...> Full Article |

 | Using the latest satellite observations, NASA researchers and others report that the Arctic is still on "thin ice" when it comes to the condition of sea ice cover in the region. ...> Full Article |
 | Ice core scientists from the British Antarctic Survey (BAS) are joint winners of a major European science prize. The European Project for Ice Coring in Antarctica (EPICA) - which retrieved two deep ice cores that have revealed how Earth's climate behaved over the last 800,000 years - is one of three projects to be awarded the 2007 Descartes Prize for excellence in collaborative research. Three winning trans-national research teams share this year's Descartes Prize of 1.36 million Euros. The prize is awarded annually to teams which have achieved outstanding scientific or technological results through collaborative research in any field of science. ...> Full Article |
 | Even now, several days after traveling to Wells, Nev., to set up a telemetry network to gain a better understanding of the magnitude 6.0 earthquake that rocked the rural Nevada community last month, Nathan Edwards shakes his head with a sense of amazement. ...> Full Article |
Global sea level has been climbing steadily over the past 80 years-and the contribution from melting ice has been more substantial than previously estimated, according to new research in Science Express.

Ten questions driving the geological and planetary sciences were identified today in a new report by the National Research Council. Aimed at reflecting the major scientific issues facing earth science at the start of the 21st century, the questions represent where the field stands, how it arrived at this point, and where it may be headed.

 | Geologists have confirmed the discovery of Earth's inner, innermost core, and have created a three-dimensional model that describes the seismic anisotropy and texturing of iron crystals within the inner core. ...> Full Article |
While the annual Sound Shake exercise on Wednesday produced a simulated magnitude 6.7 earthquake on the Seattle fault, a real though unfelt seismic event is taking place beneath western Washington.

Research from ancient sediment cores indicates that a warming climate could make the world's arctic tundra far more susceptible to fires than previously thought. The findings, published this week in the online journal, PLoS ONE, are important given the potential for tundra fires to release organic carbon - which could add significantly to the amount of greenhouse gases already blamed for global warming.

 | The rise of oxygen and the oxidation of deep oceans between 635 and 551 million years ago may have had an impact on the increase and spread of the earliest complex life, including animals, according to a new study. ...> Full Article |
An old fault zone could be to blame for the earthquake that shook the UK early today, according to a Durham University expert.

 | Researchers recently discovered the existence of direct evidence of an active geothermal system in the Teels Marsh area of Mineral County in rural Nevada. ...> Full Article |
 | Boulders the size of footballs could help scientists predict the West Antarctic Ice Sheet's (WAIS) contribution to sea-level rise according to new research published this week in the journal Geology. ...> Full Article |
Researchers studying cores of sediment collected 40 years ago have found evidence for magnetic field vortices in the Earth's core beneath the South Pole. The results contrast with earlier studies at lower latitudes, and could lead to a better understanding of processes in the core.
