Winds kick up large amounts of dust from the desert that has formed as the world’s fourth largest lake has disappeared, spreading it around the region and raising concerns about public health.
As winds pick up dirt and sand, they also pick up any microbes adhering to those particles, potentially introducing them to new locations.
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.
On Earth, the water cycle is a dominant climate force. On Mars, it’s the dust.
Jet streams sprinkle North African dust over the Amazon, providing the rain forest with much needed nutrients. Changing wind patterns and increasing smoke may shift the system.
In a happy accident, scientists found a potential solution to an atmospheric chemistry mystery. Their findings could be a missing piece in the iodine cycle and in atmospheric models.
Scientists have long assumed that dust storms lead to infections with the desert soil fungus Coccidioides, but new evidence suggests otherwise.
On Earth and throughout our solar system, ripples and dunes in sand and dust offer insights into how winds blow, liquid currents flow, and solid particles fly and bounce over the terrain.
Rapa Nui and Hawai‘i offer a tale of two island settlements: Hawai‘i was close enough to Asia for continental dust to help replenish soil nutrients depleted by agriculture. Rapa Nui wasn’t.
