Assessing net methylmercury production in changing permafrost environments in Old Crow Flats, Yukon ...
Old Crow Flats (OCF), Yukon, is a forest-tundra ecotone underlain by continuous permafrost characterized by thousands of lakes that is a crucial part of Vuntut Gwitchin First Nation's traditional territory. Permafrost degradation may have implications for mercury (Hg) cycling, as changing terra...
