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.
An Unstable Magnetic Field in Central Asia 2500-1500 Years Ago
The geomagnetic field intensity – poorly described – varies spatially and temporally on centennial time scales. A recent study fills an important gap in Central Asia and discusses global implications.
Researchers Home in on the Age of the Yangtze River
Findings on the river’s age also have implications for past landscape change in Asia.
Global Warming Intensifies Turbulence Over Northern Eurasia
A significant increasing trend of turbulence in upper atmosphere over northern Eurasia is attributed to intense anthropogenic activities.
An Innovative Approach for Investigating Subduction Slip Budgets
A new 3D model offers a state-of-the-art look at the full spectrum of slip behaviors in the Nankai subduction zone off Japan.
Measurements of Ozone-Depleting Chemicals in the Asian Monsoon
New high-altitude aircraft observations identify unexpected high levels of halogen-containing species entering the stratosphere above the summertime Asian monsoon.
Drought, Not War, Felled Some Ancient Asian Civilizations
Radiocarbon dating, luminescent sand grains, and climate records point to drought as the reason for the civilizations’ demise.
Overturning in the Pacific May Have Enabled a “Standstill” in Beringia
During the last glacial period, a vanished ocean current may have made the land bridge between Asia and the Americas into a place where humans could wait out the ice.
