Cluster member Jeff Munroe visited 20 sites last fall as part of the 2024 Collectors Tour.
Samples from the collectors become the data used as part of our source-to-sink study of how #dust moves through the #CriticalZone

We are, quite literally, made of the landscapes we inhabit – the #air we breathe, the #water we drink, the #food we eat.
In this article, contributor Nolan Monaghan explores how biophysical processes like the carbon and nitrogen cycles bridge the local and the global, laying the groundwork for a deeper, metaphysical connection with the planet.
