The American Geophysical Union, (AGU) is a world-wide scientific community for the advancement and research of Earth and Space as applied to human beings. AGU is a technical society with approximately 50,000 members comprised of scientists, teachers and students. AGU conducts conferences, meetings, publishes journals, books and weekly newsletters on geophysics and related subject matter. AGU sponsors education programs and provides on-line public access to a great deal of its work. AGU sponsors public outreach to the media for the purposes of improving science-related writing to the general public.
Collisions of coronal mass ejections can be super-elastic
Coronal mass ejections (CMEs), emissions of magnetized ionized gas from the Sun, can damage satellites and communication technology, so being able to predict where they are heading and how much energy they ...
Looking for past Honduran, Mexican civilizations
A high-tech archeological exploration team of scientists and a filmmaker, who announced a year ago that they had glimpsed remnants of what might be a fabled ancient city in the Honduran rain forests, plans ...
Scientists find extensive glacial retreat in Mount Everest region
(Phys.org) —Researchers taking a new look at the snow and ice covering Mount Everest and the national park that surrounds it are finding abundant evidence that the world's tallest peak is shedding its frozen ...
Searching for clandestine graves with geophysical tools
It's very hard to convict a murderer if the victim's body can't be found. And the best way to hide a body is to bury it. Developing new tools to find those clandestine graves is the goal of a small community ...
Charting the growth of the Turkish-Iranian plateau
Stretching from the Persian Gulf up through Turkey, the northwest-southeast running Zagros fold-and-thrust belt is a region of extensive crustal deformation and seismic activity. Near the Zagros Mountains the structure of ...
How do braided river dynamics affect sediment storage?
Braided rivers, with their continuously changing network of channels, are highly dynamic systems. Four mechanisms of channel change and evolution are considered the classic mechanisms of braided river formation: development ...
Studying how flocculation affects acoustic reflection
In inland estuaries and shallow coastal waters, small particles of organic matter, such as organic waste and debris or bacteria, clump together to form an aggregate known as floc. Flocculated particles can span a range of ...
Graphite lubricates fault zones
Graphite is known to be a low-friction material, and rocks rich in graphite are often found in fault zones. Oohashi et al. conducted laboratory studies to determine how much graphite is needed to reduce the frictional strength ...
Hydrology affects carbon storage potential of prairie potholes
Prairie potholes, the small, dynamic, unconnected ponds that dot central Canada as well as parts of the north-central United States, can store significant amounts of soil nutrients that can be transformed to carbon dioxide ...
Measuring tidal displacement using GPS
GPS is making possible high-precision, high-resolution measurements of tidal displacement that could not be achieved with other methods. Earth's surface deforms due to both body tides-the deformation of the solid Earth due ...
Extensive Antarctic campaign finds cold bias in satellite records
Advances in satellite sensing have now made it possible to track changes in the world's most remote locations. Over the Antarctic continental interior, the vast majority of profiles of atmospheric temperature are provided ...
Identifying the physical processes that control the stratigraphic record
The stratigraphic record, the sequential layers of sediment that geologists use to reconstruct the history of a landscape, has been described as "more gaps than record." The record, laid down over time as sediment settles ...
Scientists detect dark lightning linked to visible lightning
(Phys.org)—Researchers have identified a burst of high-energy radiation known as 'dark lightning" immediately preceding a flash of ordinary lightning. The new finding provides observational evidence that ...
Beachfront nourishment decisions: The "sucker-free rider" problem
Coastal communities and beachfront property owners often respond to erosion by adding sand to restore local beaches. But beach nourishment alters shoreline dynamics, not only at the replenishment site but also in adjacent ...
AGU: Wildfires can burn hot without ruining soil, new study finds
When scientists torched an entire 22-acre watershed in Portugal in a recent experiment, their research yielded a counterintuitive result: Large, hot fires do not necessarily beget hot, scorched soil.
