 | In a finding that may speed efforts to conserve oil and intensify the search for alternative fuel sources, scientists in Kuwait predict that world conventional crude oil production will peak in 2014 -- almost a decade earlier than some other predictions. Their study is in ACS' Energy & Fuels, a bi-monthly journal. ...> Full Article |
 | The massive magnitude 8.8 earthquake that struck the west coast of Chile last month moved the entire city of Concepcion at least 10 feet to the west, and shifted other parts of South America as far apart as the Falkland Islands and Fortaleza, Brazil. These preliminary measurements, done by researchers including geophysicists on the ground in Chile, paint a much clearer picture of the power behind this temblor, believed to be the fifth-most-powerful since instruments have been available to measure seismic shifts. ...> Full Article |
 | Geologists have found evidence that sea ice extended to the equator 716.5 million years ago, bringing new precision to a "snowball Earth" event long suspected to have taken place around that time. The new findings -- based on an analysis of ancient tropical rocks that are now found in remote northwestern Canada -- bolster the theory that our planet has, at times in the past, been ice-covered at all latitudes. ...> Full Article |
 | The extremely strong earthquake in Chile on 27 February this year was a complicated rupture process. Scientists ofthe GFZ German Research Centre for Geosciences analyzed the first 134 seconds of the quake. ...> Full Article |
 | A section of the Arctic Ocean seafloor that holds vast stores of frozen methane is showing signs of instability and widespread venting of the powerful greenhouse gas, according to the findings of an international research team led by University of Alaska Fairbanks scientists Natalia Shakhova and Igor Semiletov. ...> Full Article |
 | Scientists at the University of Rochester have discovered that the Earth's magnetic field 3.5 billion years ago was only half as strong as it is today, and that this weakness, coupled with a strong wind of energetic particles from the young Sun, likely stripped water from the early Earth's atmosphere. ...> Full Article |
 | Responding to challenges to the hypothesis that an asteroid impact caused a mass extinction on Earth 65 million years, a panel of 41 scientists re-analyzed data and provided new evidence, concluding that an impact in Mexico was indeed the cause of the mass extinction. ...> Full Article |
The computational science expertise at the Science and Technology Facilities Council's Daresbury Laboratory is playing a key role in enabling researchers at the National Autonomous University of Mexico, to develop a tool that will make it possible to estimate the likely impact of large magnitude earthquakes at specific locations, before they happen.

 | To help assess the potential threat of more large earthquakes in Haiti and nearby areas, scientists at the University of Texas at Austin's Institute for Geophysics are co-leading three expeditions to the country with colleagues from Purdue University, Lamont-Doherty Earth Observatory, the US Geological Survey and five other institutions. The second expedition, beginning Feb. 24, will for the first time use a scientific research vessel to examine the underwater effects of the quake. ...> Full Article |
 | The melting of glaciers is well documented, but when looking at the rate at which they have been retreating, a team of international researchers steps back and says not so fast. ...> Full Article |
 | Scientists at Columbia University's Lamont-Doherty Earth Observatory have found evidence of hydrothermal vents on the seafloor near Antarctica, formerly a blank spot on the map for researchers wanting to learn more about seafloor formation and the bizarre life forms drawn to these extreme environments. ...> Full Article |
 | At the end of the last interglacial epoch, around 115,000 years ago, there were significant climate fluctuations. In Central and Eastern Europe, the slow transition from the Eemian Interglacial to the Weichselian Glacial was marked by a growing instability in vegetation trends with possibly at least two warming events. This is the finding of German and Russian climate researchers who have evaluated geochemical and pollen analyses of lake sediments in Saxony-Anhalt, Brandenburg and Russia. ...> Full Article |
Hundreds of the world's top scientists and policymakers are expected to attend the State of the Arctic conference at the Miami Hyatt Regency from March 16-19, 2010. Speakers will include Arden Bement, director of the National Science Foundation, Jane Lubchenko, administrator of the National Oceanographic and Atmospheric Administration, and Wendy Watson-Wright, assistant director-general of the United Nations Educational, Scientific and Cultural Organization.

Scientists are gaining new insight into the mechanisms that generate huge, steep underwater waves that occur between layers of warm and cold water in coastal regions of the world's oceans.

 | The massive, 8.8-magnitude earthquake that struck Chile Feb. 27 occurred in an offshore zone that was under increased stress caused by a 1960 quake of magnitude 9.5, according to geologist Jian Lin of the Woods Hole Oceanographic Institution. ...> Full Article |
