Short summary
We collected peat porewaters across a 640 km latitudinal transect of sporadic to continuous permafrost zone and analyzed organic carbon and trace metals. There was no distinct decrease in concentration along the latitudinal transect from 62.2° N to 67.4° N. The northward migration of the permafrost boundary or the change of hydrological regime is unlikely to modify chemical composition of peat porewater fluids larger than their natural variation within different micro-landscapes.
