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.
Chase Mueller from NASA Ames Research Center shared the results of a project that uses Landsat and MODIS data to monitor water quality trends at #AGU15. We spoke with him about his findings.
Elodie Robert from the French National Center for Scientific Research presented preliminary results of her research at #AGU15 that aims to track microbiological heath hazards based on surface water turbidity in West Africa.
Courtney Reents, a graduate student at University of Illinois at Urbana-Champaign, presented a poster on forest disturbance in California at #AGU15.
William Kochtitzky, a student from Dickinson College, presented a poster on glacial changes on Peru’s Nevado Coropuna volcano at #AGU15.
Charles Perry, a Research Soil Scientist with the USDA’s Forest Inventory and Analysis group, gave a talk about his research that uses Landsat to monitor land use and land cover change in watersheds surrounding the Great Lakes at #AGU15. He is able to link the land use and land cover change information with other ancillary data to predict water quality, such as the amount of phosphorus (which feeds algae) in the lakes.
Jennifer Rover, a Geographer with the U.S. Geological Survey, gave a talk on an automated method she developed to assess long-term change to Earth’s surface using Landsat at #AGU15.
Chengquan Huang presented a poster explaining where to find U.S. forests that have been undisturbed for last 25 years at #AGU15. His research relied on Landsat to both find these forests and understand forest disturbance trends in the U.S.
Martin Goldhaber gave a talk about how climate change will impact the hydrochemistry of wetlands in an immensely important ecosystem known as the Prairie Pothole Region at #AGU15. Landsat data helped Goldhaber track how the size of the waterbodies in his study area changed between 1973 and 2011. Here’s what he shared with us about his research.
At this year’s AGU Fall meeting over 325 presentations feature research done using Landsat data. The Landsat-related papers and posters run the gamut of disciplines from cryosphere to biogeoscience to hydrology to global environmental change to natural hazards to informatics.
When you think of Southern Florida’s vast everglades, fire is not something that usually comes to mind, but the region has a long history of seasonal fires.
Capitalizing on the long Landsat data record and the human brain’s capacity to recognize movement, Frank Paul from the University of Zurich has created glacier animations that enable viewers to witness the complex flow of glaciers.
Every part of the mosaic of Earth’s surface — ocean and land, Arctic and tropics, forest and grassland — absorbs and releases carbon in a different way. Wild-card events such as massive wildfires and drought complicate the global picture even more. To better predict future climate, we need to understand how Earth’s ecosystems will change as the climate warms and how extreme events will shape and interact with the future environment.
Ice sheets are in perpetual motion, making their way downslope like a river. If the amount of snow that an ice sheet accumulates does not keep pace with its loss to the sea, sea level will rise. As temperatures have climbed, positive feedback loops have led to an accelerated loss of ice sheet sections that touch the sea, but in an unexpected twist to the global warming saga, scientists have just discovered a negative feedback loop that is slowing down the Greenland Ice Sheet sections that end on land—a sliver of good news for sea-level rise.
Parker Dam was constructed on the California-Arizona border on the lower Colorado River during the 1930s, as part of a project to employ people during the Great Depression, to generate electricity, and to provide water that could be pumped into aqueducts for agricultural, industrial, and residential use in other parts of Arizona.
The World Economic Forum has published a talk given by Illah Nourbakhsh, professor of robotics from Carnegie Mellon and Matthew Hansen, a remote sensing specialist at the University of Maryland, that demonstrates how visualizing big data can revolutionize the way we understand and imagine the world.
