Radiosondes Measure Atmospheric Turbulence Over North America
Analyses of high-resolution radiosonde balloon measurements have provided a novel climatology of atmospheric turbulence parameters in the troposphere and lower stratosphere.
Groundwater Drawn Downward After Kumamoto Quake
A unique set of high-frequency groundwater level monitoring reveals a loss of approximately ten million cubic meters of groundwater after a major earthquake.
Curiosity Monitors Rare Global Dust Storm From Mars’s Surface
Since the 1970s, no surface platform had made meteorological measurements of a global dust storm on Mars, but last summer NASA’s Curiosity rover witnessed one of these rare events.
Small Seismic Signals Tell a Story of Iceberg Calving
Seismic signals detected hundreds of kilometers away from Greenland glaciers reveal the calving style and iceberg size.
The Lower Mantle May Have a Wet Bottom
Molecular dynamics calculations suggest that molten hydrogen-bearing iron peroxide (FeO2Hx) may produce the ultra-low velocity zones that occur at the core-mantle boundary.
Human-made Emissions Modify Electron Space Environment
Very Low Frequency transmitters used for communications with submarines modify the dynamics of energetic electrons in the inner radiation belt and the slot region.
Lomonosov: The Crater That Started a Martian Mega Tsunami
Three billion years ago, on Mars, the shores of an ocean may have been flooded by a mega-tsunami. Now the crater left by the bolide impact that probably triggered the tsunami has been identified.
Landslide Activity Ramps Up With Extreme Rainfall
An increase in activity of hundreds of slow-moving landslides during extreme wet conditions in California provides insights into the landscape response to ongoing climate change.
Revealing the Arctic Crust
A new model, ArcCRUST, reveals with unprecedent resolution the geometry and the thermal state of the oceanic crust of the High Arctic and Circum-Arctic domain.
