Geologists have improved upon methods to map seabed rocks, helping us better understand underwater earthquakes and the tsunamis they can cause.
Stanford researchers have analyzed mountain ranges worldwide to show that a theory relating erosion and mountain height doesn't always add up.
Using an automated method to create a high-resolution map of the seismic velocity below the seafloor, researchers from Kyushu University found a large-scale gas reservoir in an area where the Earth's upper layers are being separated. This reservoir, the first of its kind, and the potential for others like it could have implications from natural resource or environmental standpoints depending on whether the trapped gas is methane or carbon dioxide and whether it remains trapped.
A new model for plasma flow within the sun provides novel explanations for sunspots, the 11-year sunspot cycle, solar magnetic reversals and other previously unexplained solar phenomena.
Weathering of subsurface rock in the Southern Sierra Nevada Mountains of California occurs due more to rocks expanding than from chemical decomposition.
New geophysics research challenges the conventional view of how a vital and life-sustaining feature of weathered rock is created.
The sea-ice extent in the Arctic is nearing its annual minimum at the end of the melt season in September. Only circa 3.9 million square kilometres of the Arctic Ocean are covered by sea ice any more, according to researchers from the Alfred Wegener Institute and the University of Bremen.
Groundwater is essential for growing crops, but new research shows climate change is making it harder for soil to absorb water from rainfall. While the idea that soil particles rearrange in response to environmental conditions is not new, scientists once thought these shifts happened slowly. Not anymore. New research shows increased rainfall reduces the rate water moves into soil, and that this change only takes a few years or decades, not centuries as previously assumed.
Nuclear reactors are still the primary source for strong neutron beams to create isotopes for geologic dating, radiography and medicine, but researchers at UC Berkeley have enlisted engineering students in building a tabletop neutron source that could be nearly as effective. A new study shows that the high flux neutron generator can date rocks as old as 1 million years, as well as fine-grained materials like lavas and clays, extending the usefulness of argon-argon dating.
After noticing how the construction of dams significantly alter the hydrodynamics of natural rivers and the resulting downstream riverbed evolution, researchers decided to apply numerical simulations to help determine what's at play in the relationship of sediment motion and flow conditions.
