Spacecraft observations and model simulations provide new insights into tidal patterns that transport momentum and energy into the planet’s upper atmosphere.
A Dive into the Deep Earth
In July, Eos looks at the incredible capabilities scientists have developed to recreate the enormous pressures and temperatures that exist far below the planet’s surface.
Earth’s Core Is in the Hot Seat
How old is Earth’s inner core? High-pressure and high-temperature experiments suggest that our planet’s inner furnace may be much younger than expected.
Modeling Under Pressure
At a critical moment in the effort to end one of the world’s worst oil spills, one scientist holed up in his office and pulled an all-nighter to calculate the well’s aquifer support.
Fluid Pressure Changes Grease Cascadia’s Slow Aseismic Earthquakes
Twenty-five years’ worth of data allows scientists to suss out subtle signals deep in subduction zones.
Fugitive Gas Abetted by Barometric Pressure
Barometric pressure, in addition to factors such as lithology and the depth of the water table, can influence patterns of natural gas that escapes to subsurface soils.
New Definition of Potential Spicity by the Least Square Method
A thermodynamic function of the potential spicity is defined and it is orthogonal to the potential density in the least square sense.
Potential Spicity: From Abstract Theory to Practical Application
A method for estimating potential spicity, a thermodynamic variable in oceanography, provides a new way to describe contrasts in watermass properties.
What Happens to Minerals as They Get Squeezed in the Mantle?
Researchers test how different minerals found in the Earth’s mantle respond to high temperatures and pressures.
Low Heliosphere Pressure Drives Wide CMEs in Weak Solar Cycles
Why are coronal mass ejections from the current solar cycle wider than others? Researchers investigate.
