New measurements of impact craters on Mercury’s smooth plains suggest that the topography of the solar system’s innermost planet is changing at twice the rate of landforms on the Moon.Read More »Geology & Geophysics
An analysis of tide gauge records and physical models shows acceleration of sea level rise on the East Coast due to melting of the Greenland Ice Sheet is especially pronounced south of 40°N latitude.Read More »Climate Change
The results of new simulations that account for internal climate variability contrast with previous projections of how this vital West Coast current will respond to anthropogenic warming.Read More »Geochemistry, Mineralogy, Volcanology
Thermal convection in deep interiors could be more vigorous in carbide planets than in comparably sized silicate planets, according to new high-pressure measurements of silicon carbide.Read More »Planetary Sciences
A three-dimensional model of material transport suggests that impact cratering can mix lunar soils across distances of more than 100 kilometers.Read More »Geochemistry, Mineralogy, Volcanology
A study of deformed and metamorphosed rocks exposed in Tibet’s Lopu Range suggests that episodes of crustal shortening and extension during the evolution of the Himalaya are related to subduction processes.Read More »Geology & Geophysics
To understand the ancient movement of Earth’s tectonic plates, comprehensive magnetic and petrographic studies are needed to detect secondary magnetization in carbonates and other sedimentary rocks.Read More »Hydrology, Cryosphere & Earth Surface
A study questions whether the hydraulics of rivers that lack loose sediments along their bottoms can be accurately depicted by standard equations for flow over sediment.Read More »Geology & Geophysics
Uranium-lead dating of zircons from Taiwan’s east central metamorphic belt offers robust evidence that this uplifted terrane is some 90 million years younger than previously thought.Read More »Atmospheric Sciences
