Could cryoturbic diapirs be key for understanding ecological feedbacks to climate change in High Arctic polar deserts?

Mitsuaki Ota, Steven Mamet, Amanda Muller, Eric Lamb, Gurbir Dhillon, Derek Peak & Steven Siciliano
High Arctic polar deserts cover 26% of the Arctic. Increasing temperatures are predicted to significantly alter polar desert freeze-thaw and biogeochemical cycles, with important implications for greenhouse gas emissions. However, the mechanisms underlyingthese changing cycles are still highly uncertain. Cryoturbic, carbon-rich Bhy horizons (diapirs) in frost boils are key nutrient sources for Salix arctica. We hypothesized that diapirism leads to organic carbon characteristics that alter microbial pathways, which then control root foraging and greenhouse gas...
