This peatland database was created in 2013 to facilitate data accessibility and encourage collaborative work within the peatland scientific community. The wide biogeosciences research community can also use the freely available dataset presented here.
Understanding how biogeochemical processes and ecosystem dynamics respond to hydrological and climatological changes is crucial in the current context of global change. Peatlands constitute important water, carbon, and nitrogen reservoirs whose exchanges with the atmosphere, the biosphere, and the hydrosphere must be better quantified and understood. Currently, our data repository includes 268 peat core records from 215 sites located in the northern hemisphere. This valuable information can help resolve fundamental questions related to past, present, and future carbon and nutrient cycling in peatlands.
