Evolutions of Non‐oxygenated Compounds in Sunlit Subarctic Thermokarst Pond Surface Waters

Abstract With global climate change, ground subsidence caused by permafrost thawing leads to the formation of thermokarst ponds, where organics from eroding permafrost accumulate in part as dissolved organic matter (DOM). Surface waters were collected from two subarctic thermokar...

Microbial communities and ecological functions shift with glacier retreat in the Canadian High Arctic

Abstract Glaciers are rapidly retreating under climate warming, raising concerns about the loss of unique microbial ecosystems in both glacier ice and forelands. However, the changes in microbial diversity, community structure, and functional traits across the glacier ice-forelan...

Modelling mineral dust emissions from proglacial valleys of the St. Elias Mountains, Canada

Abstract. Proglacial valleys of western Canada and Alaska demonstrate extensive historical and contemporary records of mineral dust emissions. These contributions remain unresolved by current dust emission modelling and unaccounted for in global emission estimates. We developed a...
