Purpose: Peat accumulation in high latitude wetlands represents a natural long-term carbon sink, resulting from the cumulative excess of growing season net ecosystem production over non-growing season (NGS) net mineralization in soils. With high latitudes experiencing warming at a faster pace than the global average, especially during the NGS, a major concern is that enhanced mineralization of soil organic carbon will steadily increase CO2 emissions from northern peatlands. In this study, we conducted laboratory incubations with soils from boreal and temperate peatlands across Canada.
Abstract: This dataset contains results from laboratory soil incubations with peat samples of different depth intervals retrieved at seven Canadian peatland locations. CO2 release fluxes (and CH4 fluxes for some samples) from peat samples were measured using Li-8100 and Li-8150 system under variable moisture levels across a temperature sequence ranging from -10 to 35 °C in an environmental chamber. The resulting CO2 production rates were fitted to equations describing the observed moisture and temperature trends.
