Cobalt may have played in important role in the early development of life on Earth, and been more available to ancient life than modern due to the higher mafic composition of early continents.Read More �
Ten years of high-resolution gridded NEXRAD radar data provide a new data set to quantify tropopause-overshooting convection over the continental United States.Read More �
Polynomial chaos and Bayesian compressive sensing are applied to a land surface model to understand how large numbers of tunable parameters interact and may be optimized.Read More �
Enigmatic surface features on Venus called coronae are important for how Venus loses heat, and measurement of surface flexing around these features indicates higher heat flows than on Earth.Read More �
Rapid elevation-rise in Turkey, tracked by marine sediments that now sit at 1.5 km in elevation, is linked to deep-Earth processes that can explain short-lived, extreme rates of topographic change.Read More �
By comparing Cassini observations spanning ten years, Saturn’s equatorial oscillation is shown to have similarities to Earth’s Quasi-Biennial Oscillation and Semi-Annual Oscillation.Read More �
A stochastic sediment routing model for river networks is inverted to determine sediment source areas based on point observations of grain size and sediment flux at the basin outlet.Read More �
Imperfect knowledge of high-latitude forcing of the coupled ionosphere-theremosphere system translates into uncertainty in the low-latitude and midlatitude response to a geomagnetic storm.Read More �
Layered-ejecta craters on Mars that are associated with impacts into rock mixed with volatiles have been formed throughout the planet’s history indicating the long-term preservation of subsurface ice.Read More �
