New paper by Cardinal et al. on #permafrost mercury examines the impacts of landscape evolution in a degrading lithalsa field near Kangiqsualujjuaq, Nunavik. www-sciencedirect-com.acces.bibl.ulaval.ca/science/arti...

It indicates that the proportion of mercury that is methylated in near surface sediment was 0.57% on the lithalsa, increased to 6.9% in yound thaw ponds, decreased to 4.8% when Carex spp where widespread in the pond, and to 2.6% when Sphagnum spp. established in the depression.
