ABSTRACT Understanding changes in snow distribution permafrost ecosystems is fundamental to predicting their response future climate change. The expansion of tall shrubs into tundra can trap and insulate during the winter, but overall insulation effect dependent upon many ecosystem properties. To study shrub–snow–ground interactions, small temperature sensors were deployed at two research sites on Seward Peninsula Alaska, USA, 2019–2020 winter. Snow temperatures used extrapolate multiple...
Abstract Rainfall frequency and intensity are expected to increase in the Arctic, with potential detrimental impacts on permafrost, leading enhanced thawing carbon release atmosphere. However, there have been very few studies effect of discrete rain events permafrost Arctic sub-Arctic. Conducting controlled rainfall experiments within landscapes can provide an improved understanding changing intensity, duration, timing tundra ecosystems. Here, we describe design implementation...
