How do Bob and Tom Eddies Meet, Pair-Spin, and Twist?
Autonomous float data reveal that mergers of two eddies, known to have spiraling subducting water surrounding each other, happens more frequently than previously thought.

Asian Dust Flux into Philippine Sea Increased During Miocene
A new deep sea dust record from the Philippine Sea, when added to evidence from the NW Pacific, suggests how dust may record a change in dustiness or the position of wind transport.
