Description
Erin Rooney and Angela Possinger measured soil freeze-thaw cycles across North America in 2024. Such cycles reshape soil structure and its chemistry. Knowing what drives them could help predict how ecosystems answer a warming climate.
The pair counted cycles at forty sites in a national observatory network. Sites were grouped as warm and wet, warm and dry, or cold and dry. Warm, dry sites had the most cycles, driven by fast daily swings near the surface in winter. Cold, dry sites had fewer but longer cycles, mostly in spring, and more of them where the organic mat ran thick. A steady snowpack buffered soil from temperature swings, an effect that depended on the climate group.
