Cryogenic Soil Activity along Bioclimatic Gradients in Northern Sweden: Insights from Eight Different Proxies
ABSTRACT Cryogenic soil activity caused by differential soil movements during freeze‐thaw cycles is of fundamental importance for Arctic ecosystem functioning, but its response to climate warming is uncertain. Eight proxies of cryogenic soil activity (including measurements of soil surface motion, v...

ABSTRACT Cryogenic soil activity caused by differential soil movements during freeze‐thaw cycles is of fundamental importance for Arctic ecosystem functioning, but its response to climate warming is uncertain.
