Abstract
Multi-proxy analyses are realised to reconstruct Holocene carbon accumulation dynamics and paleohydrological conditions on two peat cores collected in a permafrost peatland located near Kuujjuarapik (55°13’N. 77°41’W). Results from the center of the peatland show synchronic changes with the water level variations of several northern Quebec lakes. Two possible permafrost aggradation phases have been identified: 1400 – 660 cal. BP and 400 – 140 cal. BP. Our results also show the influence of permafrost aggradation on carbon accumulation with importants lowering reaching 11.02 g.m-2.yr-1 and 8.62 g.m-2.yr-1 during these two cold periods.
