  • 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 ...

  • Promising results of environment monitoring satellite Jason-2 one week after launch

    One week has gone by since the launch, and everything is going very well with Jason-2. While the satellite is not yet in its final orbit (to be reached on 3 July), the first test measurements and calibrations have started. EUMETSAT, CNES, NASA and NOAA are cooperating to test every component of the ground segment, and results are looking very promising. The first Doris (Doppler Orbitography and ...

  • Study: A third of global groundwater basins are overstressed

    Satellite data show people are overdrawing water from some of the world's largest groundwater basins. Researchers from the University of California, Irvine say it's unclear how much water is left in the most overburdened aquifers. The problem is expected to worsen with climate change and population growth. Using measurements taken by NASA's twin Grace satellites, scientists found the most ...

  • Fracking yields high wintertime ozone pollution

    Chemicals released into the air by oil and gas exploration, extraction and related activities (i.e. horizontal drilling combined with hydraulic fracturing “fracking”) can spark reactions that lead to high levels of ozone in wintertime, high enough to exceed the US federal health standards, according to new NOAA-led research, published in ...

  • 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 ...

  • Scientists say lakes to feel climate change impact

    German and Japanese scientists have discovered that lakes located in the planet's warmer and colder regions will fall victim to climate change. Their data showed that the deep water layers of lakes in the south of Japan recorded higher temperatures, whereas temperatures of those in the north of the country were unchanged. Their findings were published in the Geophysical Research Letters. The ...

  • Disasters in Europe: more frequent and causing more damage

    The number and impacts of disasters have increased in Europe in the period 1998-2009, a new report by the European Environment Agency (EEA) concludes. The report assesses the frequency of disasters and their impacts on humans, the economy and ecosystems and calls for better integrated risk disaster management across Europe. The Agency's new report ' ...

  • Ancient glacial sediments drag down Louisiana`s sinking coast

    Sediments deposited into the Mississippi River Delta thousands of years ago when North America's glaciers retreated are contributing to the ongoing sinking of Louisiana's coastline, finds new research by NASA and scientists at Louisiana State University. The weight of these sediments is causing a large section of Earth's crust to sag at a rate of 0.04 to 0.3 inches a year, the study determined. ...

  • Human pollution drives weekday southeast storms

    Summertime storms in the southeastern United States drop more rainfall midweek than on weekends, and NASA scientists say air pollution from human activities, such as emissions from traffic, businesses and factories, is likely driving that trend. The link between rainfall and the day of the week is evident in data from NASA's Tropical Rainfall Measuring Mission satellite, known as TRMM. 'It ...

  • 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 ...


  • 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 ...

  • Modis images amazon drought impact

    A NASA-funded study has revealed widespread reductions in the greenness of Amazon forests caused by last year's record-breaking drought. Computer models predict a changing climate with warmer temperatures and altered rainfall patterns, which could lead to rainforests being replaced by grasslands or woody savannas. Carbon stored in rotting wood would then be released into the atmosphere, ...
