  • ASTM D6429 - 99(2011)e1 standard guide for selecting surface geophysical methods

    This guide applies to commonly used surface geophysical methods for those applications listed in Table 1. The rating system used in Table 1 is based upon the ability of each method to produce results under average field conditions when compared to other methods applied to the same application. An “A” rating implies a preferred method and a “B” rating implies an alternate ...

  • Gas hydrate: A realistic future source of gas supply?

    A Department of Energy scientist writes in this week's Science magazine that a search is underway for a potentially immense untapped energy resource that, given its global distribution, has the potential to alter existing energy production and supply paradigms. In the article, Is Gas Hydrate Energy Within Reach?, Dr. Ray Boswell, technology manager for the Office of Fossil Energy’s National ...

  • Study Evaluates Critical Mineral-Resource Potential in Alaska

    A new method for evaluating the resource potential for large, underexplored regions for critical minerals in Alaska is now available online. Critical minerals are used in products that are vital to national security, technology, and also play an integral role in our everyday modern life. The U.S. Geological Survey in collaboration with the Alaska Division of Geological & Geophysical Surveys ...

  • Space tech helps to find natural resources

    Using space-based technology developed during ESA’s gravity mission studies, a novel gradiometer is being developed by a UK-based company to help oil and gas companies find the most appropriate locations to drill wells and plan further exploration. The gravity gradiometer measures the variations in the Earth’s gravity, or in technical terms, the ‘differential acceleration’. These variations ...

  • Triad expedites brownfields redevelopment in Fairbanks

    The Fairbanks North Star Borough (FNSB) used Triad in 2006-2007 to assess environmental conditions at a municipal property along the Chena River in Fairbanks, AK. FNSB accelerated the site investigation as part of a brownfields assessment grant received from the U.S. EPA in 2005. Low-level contamination had been identified onsite in past investigations, but its extent and impact on future ...

  • Kutztown University uses GPR to map cemetery

    In an attempt to determine if bodies originally buried at an old cemetery behind the present historical society were re-interred, university students and their professor spent Friday afternoon examining the old cemetery. Roughly a dozen students from Kutztown University and their instructor, Professor Laura Sherrod, used a magnetometer and ground penetrating radar to search for ...

  • First research links California quakes to oil operations

    A 2005 spate of quakes in California's Central Valley almost certainly was triggered by oilfield injection underground, a study published Thursday said in the first such link in California between oil and gas operations and earthquakes. Researchers at the University of California at Santa Cruz, the University of Southern California and two French universities published their findings Thursday in ...

  • States Confront Worries About Fracking, Quakes

    Earthquakes used to be almost unheard of on the vast stretches of prairie that unfold across Texas, Kansas and Oklahoma. But in recent years, temblors have become commonplace. Oklahoma recorded nearly 150 of them between January and the start of May. Most were too weak to cause serious damage or endanger lives. Yet they've rattled nerves and raised suspicions that the shaking might be ...

  • 39-mile dredging/capping approach used to treat fox river PCBsd

    The Lower Fox River in Wisconsin contains approximately 8 million yd3 of PCB-contaminated sediment targeted for active remediation. The site's records of decision (RODs) were amended in 2007 and 2008 to specify dredging of nearly 4 million yd3 of sediment with high concentrations of PCBs, followed by in situ capping of approximately 560 acres of sediment comprising operable units (OUs) 1 through ...

  • MOE presents: provincial water monitoring networks

    Dave Rudolph – "Emerging Needs for Temporal and Spatial Data Precision" Dave Rudolph, with the University of Waterloo, started the symposium off with a very thought provoking presentation on the value of data.
