  • 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 ...

  • AAPG joins SEG in publishing new journal for interpreters

    The American Association of Petroleum Geologists (AAPG), the world's largest professional geological society, will join with the Society of Exploration Geophysicists (SEG), the largest international society dedicated to applied geophysics, in the publication of a new, peer-reviewed journal for advancing the practice of subsurface interpretation. INTERPRETATION will comprise papers directly ...

  • U.S. on thin ice in Arctic

    With the climate problem growing more urgent every year, the United States is not well prepared for a changing Arctic, and its continued dependence on fossil fuels only makes the situation more serious. The recent climate science, as explored in WRI’s Climate Science 2009-2010: Major New Discoveries, shows that the Arctic is indeed ...

  • EPA investigates US hazardous waste site for soil & groundwater contamination

    The U.S. Environmental Protection Agency is conducting a geophysical survey and will conduct a preliminary assessment of an illegal disposal site known as the Smith and Thompson Pumping Company Site in Lancaster, California. Court-ordered surface clean-up of the site is complete; the EPA’s investigation will determine if hazardous waste is buried underground. 'We’re conducing a thorough ...

  • ZZ has attended the 9th SAEMC conference

    ZZ Resistivity Imaging has attended the SAMEC conference in Adelaide in 2012. Over the years, we had developed competency in providing cost effective resistivity surveys, including surface, borehole-surface and crosshole resistivity surveys.

  • Jason-2 begins mapping oceans

    Less than a month after the launch of the Jason-2 ocean altimetry satellite, the Ocean Surface Topography Mission has produced its first complete maps. The maps were calculated from the first 10 days of Jason-2’s operational orbit starting on 4 July. After reaching its operational orbit some 1,336 km above the Earth at a 66º inclination, Jason-2 and its experimental predecessor, Jason-1, began ...

  • Less Air Pollution Would Mean New California Dams Not Needed

    STANFORD, California (ENS) - Governor Arnold Schwarzenegger recently called for new dams in Northern California and near Fresno to store more water from Sierra snowmelt - an initiative criticized by environmentalists. Now a Stanford University scientist says the elimination of aerosol pollution would offset some of the need for additional dams by increasing rainwater supply. ...

  • Earth`s lakes are warming - NASA research of 167 large lakes worldwide

    In the first comprehensive global survey of temperature trends in major lakes, NASA researchers determined Earth's largest lakes have warmed during the past 25 years in response to climate change. Researchers Philipp Schneider and Simon Hook of NASA's Jet Propulsion Laboratory in Pasadena, CA, USA, used satellite data to measure the surface temperatures of 167 large lakes worldwide. They reported ...

  • NASA: Global Warming Will Bring More Severe Storms

    NEW YORK, New York, August 30, 2007 (ENS) - The most violent severe storms and tornadoes may become more common as Earth’s climate warms, say scientists with the National Aeronautics and Space Administration, NASA, using a new climate model. The scientsts predict that in a warmer climate, stronger and more severe storms can be expected, but with fewer storms overall. Previous climate model ...

  • ASTM D5777 - 00(2011)e1 standard guide for using the seismic refraction method for subsurface investigation

    This guide summarizes the equipment, field procedures, and interpretation methods used for the determination of the depth, thickness and the seismic velocity of subsurface soil and rock or engineered materials, using the seismic refraction method.

  • Volatile dense chemical liquids in groundwaters can produce slowly bubbling gas flow

    Despite decades of research, the cleanup of soil and groundwater contaminated by dense non-aqueous phase liquids (DNAPLs) used in numerous industrial applications remains a daunting challenge. These compounds, including degreasers, dry cleaning fluids, creosote, solvents and coal tar, when present below ground can generate hazardous concentrations for decades to centuries as they dissolve into ...

  • Figuring out where to put the carbon

    To meet our immediate energy needs without exacerbating climate change, most experts agree, we’ll need to find a way to store the carbon dioxide given off by the combustion of coal, oil and natural gas. But no full-scale storage systems exist, and the plans to create them have many unknowns. New projects at MIT could help to fill that information gap. At the American Geophysical Union’s fall ...
