Dust Storms Spotted for First Time on Titan
Data from NASA's Cassini spacecraft revealed what appear to be giant dust storms in equatorial regions of Saturn's moon Titan, making it the third solar system body, besides Earth and Mars, where dust storms have been observed.
Arctic Ice Sets Major Ocean Current's Speed
The Marshall Group has identified an “ice-ocean governor" mechanism, whereby Arctic ice cover helps regulate the speed of the massive Beaufort Gyre and how much fresh water it stores—with implications for global climate as long-term melting increases its speed and intensity.
Faster, cheaper modeling method could improve understanding of long-term atmospheric chemistry and provide a powerful risk assessment tool.
