The ocean's living carbon pumps
When we talk about global carbon fixation – "pumping" carbon out of the atmosphere and fixing it into organic molecules by photosynthesis – proper measurement is key to understanding this process. By ...
A global surge of great earthquakes from 2004-2014 and implications for Cascadia
The last ten years have been a remarkable time for great earthquakes. Since December 2004 there have been no less than 18 quakes of Mw8.0 or greater – a rate of more than twice that seen from 1900 to mid-2004. ...
Rising above the risk: America's first tsunami refuge
Washington's coast is so close to the seismically active Cascadia Subduction Zone that if a megathrust earthquake were to occur, a tsunami would hit the Washington shoreline in just 25 minutes.
What Antarctica's past reveals about future climate
Bella Duncan is researching Antarctica's past climate between 25 million and four million years ago, which includes the Miocene and Pliocene geological epochs.
Eucla Basin survey uncovers odd rock formations
Geologists have come to the tentative conclusion that relatively young Mesoproterozoic bedrock lies deep beneath the Nullabor, wedged between two much older formations.
NASA sees Gonzalo affect Bermuda's ocean sediment: Stirred, not shaken
NASA's Aqua and Terra satellites captured before and after images of Bermuda and surrounding waters before and after Hurricane Gonzalo struck the island on Oct. 17. The images revealed how Gonzalo stirred ...
Aqua satellite sees Tropical Storm Ana still affecting Hawaii
Slow-moving Tropical Storm Ana was still affecting parts of Hawaii on Oct. 20 when NASA's Aqua satellite passed overhead from its orbit in space. Imagery from Aqua showed that wind shear was affecting the ...
Data shows fewer tornado days in U.S. but more per event over past couple decades
Understanding oceanic earthquake precursors
Published on 14 September in Nature Geoscience, a study conducted by researchers from several institutes, including IFREMER (French Research Institute for Exploitation of the Sea), CNRS and IFSTTAR, offers the first theore ...
Massive debris pile reveals risk of huge tsunamis in Hawaii
A mass of marine debris discovered in a giant sinkhole in the Hawaiian islands provides evidence that at least one mammoth tsunami, larger than any in Hawaii's recorded history, has struck the islands, and ...
Australian volcanic mystery explained
Scientists have solved a long-standing mystery surrounding Australia's only active volcanic area, in the country's southeast.
Mysterious Midcontinent Rift is a geological hybrid
An international team of geologists has a new explanation for how the Midwest's biggest geological feature—an ancient and giant 2,000-mile-long underground crack that starts in Lake Superior and runs south ...
Pollution-coated particles bypass ice formation, but influence clouds
Wrapped in pollution, dust diverts from its usual course and steers clear of water. The result, found researchers at Pacific Northwest National Laboratory, closes one more gap in understanding how—and when—cloud ...
Peru glaciers shrink 40% in 44 years: government
Peru's glaciers have shrunk by more than 40 percent since 1970 because of climate change, giving birth to nearly 1,000 new lagoons, national water authority ANA said Thursday.
