Dec 16, 2015Assessing Longwall Mining Impacts on the Forests Above

Erin Pfeil-McCullough, a graduate student at the University of Pittsburgh, gave a talk at #AGU15 on insights that she has gained from her research to determine what impacts longwall mining has on forest canopies above as the ground subsides and local hydrology is altered.

May 9, 2013Landsat Images Provide the Gold Standard for New Earth Applications

May 9, 2013 • Images from Landsat satellites provided free to the public by the Department of the Interior’s U.S. Geological Survey were the starting points for “a new breakthrough” reported today by Time and announced on the Official Google Blog. Using its Earth Engine technology, Google has compiled decades of Landsat images into a new, interactive time-lapse […]

Yellowstone National Park
Aug 7, 2011Landsat Satellites Track Yellowstone’s Underground Heat

Aug 7, 2011 • Yellowstone National Park sits on top of a vast, ancient, and still active volcano. Heat pours off its underground magma chamber, and is the fuel for Yellowstone’s famous features—more than 10,000 hot springs, mud pots, terraces and geysers, including Old Faithful. But expected development by energy companies right outside Yellowstone’s borders […]

Feb 10, 2008Establishing Historical Land Cover

Feb 10, 2008 • USGS and NASA researchers teamed together in a highly ambitious effort to reconstruct historical land cover and biophysical parameters of the eastern U.S. Their resulting data sets will support future climate modeling, studies concerning the impact of historical land cover change on water, energy and carbon budgets (and cycles), as well […]

Jul 2, 2007Landsat Helps Document Alaska Coastal Erosion

Jul 2, 2007 • An article by U.S. Geological Survey (USGS) scientists on documentation of coastal land loss, lake expansion and drainage in Alaska from 1955–2005 was recently published in the July issue of Geology, a Geological Society of America publication. In analyzing Landsat data and topographic maps compiled from aerial photographs, scientists found that […]
