  • 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 ...

  • Study to Uncover Yellowstone’s Subsurface Mysteries

    A new study providing an unprecedented regional view of the earth’s crust beneath Yellowstone National Park will begin with a helicopter electromagnetic and magnetic (HEM) survey on November 7, 2016. Scientists from the U.S. Geological Survey, University of Wyoming and Aarhus University in Denmark hope to distinguish zones of cold fresh water, hot saline water, steam, clay and unaltered ...

  • Study Links California Drought to Global Warming

    A new study is asserting a link between climate change and both the intensifying California drought and the polar vortex blamed for the recent harsh winter. Usually, researchers make those links years later, but this study does it in real time. Utah State University scientist Simon Wang who wrote the study say he hopes what he found can help researchers predict the next big weird winter. ...

  • 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 ...

  • Wildfires worse due to global warming, studies say

    The devastating wildfires scorching Southern California offer a glimpse of a warmer and more fiery future, according to scientists and federal and international reports. In the past three months, at least three different studies and reports have warned that wildfires are getting bigger, that man-made climate change is to blame, and it's only going to get worse with more fires starting ...

  • Study links hundreds of Ohio quakes to fracking

    A new study suggests fracking triggered hundreds of small, unnoticeable earthquakes in eastern Ohio late last year, months before the state first linked seismic activity to the much-debated oil-and-gas extraction technique. The report, which appears in the November issue of the journal Seismological Research Letters, identified nearly 400 tremors on a previously unmapped fault in Harrison County ...

  • Study links African drought to Pacific sea temperature

    Researchers in the United States have found a link between low rainfall in East Africa during the March-May rainy season, and changes in sea surface temperature in the tropical Pacific Ocean. The region endured a catastrophic ...

  • NASA Study Projects Warming-Driven Changes In Global Rainfall

    A NASA-led modeling study provides new evidence that global warming may increase the risk for extreme rainfall and drought. The study shows for the first time how rising carbon dioxide concentrations could affect the entire range of rainfall types on Earth. Analysis of computer simulations from 14 climate models indicates wet regions of the world, such as the equatorial Pacific Ocean and Asian ...

  • Satellite Study Reveals Parched U.S. West Using Up Underground Water

    A new study by NASA and University of California, Irvine, scientists finds more than 75 percent of the water loss in the drought-stricken Colorado River Basin since late 2004 came from underground resources. The extent of groundwater loss may pose a greater threat to the water supply of the western United States than previously thought. This study is the first to quantify the amount that ...

  • New USGS study documents rapid disappearance of Antarctica`s ice shelves

    Possible Forecast for Continued Antarctica Glacier Loss and Sea-Level Rise Due to Climate Change. Antarctica's glaciers are melting more rapidly than previously known because of climate change, according to a new U.S. Geological Survey report prepared in close collaboration with the British Antarctic Survey. The USGS study documents for the first time that one ice shelf has completely disappeared ...

  • NASA study illustrates how peak oil impacts climate crisis

    The burning of fossil fuels - notably coal, oil and gas - has accounted for about 80 percent of the rise of atmospheric carbon dioxide since the pre-industrial era. Now, NASA researchers have identified feasible emission scenarios that could keep carbon dioxide below levels that some scientists have called dangerous for climate. When and how global oil production will peak has been debated, ...

  • Microbe community deep beneath Arctic permafrost needs study, scientist tells AGU

    A community of microbes, living in a frigid layer of gas hydrates deep beneath the Arctic permafrost, has piqued the interest of scientists who say a better understanding of that environment is important because it is both a potential fuel source and record of climate change. Frederick “Rick” Colwell, a microbiologist from Oregon State University, shared the results of his research at the annual ...

  • Landmark US Geological Survey study demonstrates how methylmercury, known to contaminate seafood, originates in the ocean

    A new landmark study published today documents for the first time the process in which increased mercury emissions from human sources across the globe, and in particular from Asia, make their way into the North Pacific Ocean and as a result contaminate tuna and other seafood. Because much of the mercury that enters the North Pacific comes from the atmosphere, scientists have predicted an ...

  • University of Colorado Professor to Lead NASA Campaign to Study North American Air Quality

    A University of Colorado Boulder professor is leading a major NASA airborne science campaign this summer that will probe weather patterns and air pollution over a vast expanse of North America that have potential global climate consequences. The campaign, known as the Studies of Emissions, Atmospheric Composition, Clouds and Climate Coupling by Regional Surveys, or SEAC4RS, will allow researchers ...
