WELCOME TO THE DUST^2 CLUSTER

A source-to-sink investigation of the dust system in the southwestern US as a component of the critical zone.

Thanks to all who participated in the DUST^ 2 Workshop!

This event was held at the University of Utah in Salt Lake City, April 21-24, 2022. Approximately 40 attendees learned about the the projects forming the core of DUST^2, shared poster presentations, took field trips to the Great Salt Lake and into the Wasatch Mountains, began writing a review paper on Dust in the Critical Zone, and brainstormed future research directions. Thanks to the participants and to NSF for supporting this successful event!

About the Dust^2 Cluster

The emission, transport, and deposition of mineral dust plays a key role in functioning of the critical zone. This is especially true in mountain environments where dust deposition has been shown to alter the pH and chemistry of surface water, contribute to soil formation, deliver important plant available nutrients, and decrease the albedo of snow, causing earlier snowpack melt.
