Stratigraphic controls on pool formation in a domed bog inferred from ground penetrating radar (GPR)

GPR and EM31 surveys across Sphagnum pools (defined here as Sphagnum filled wet depressions) suggest a continuous sequence of underlying lake sediment and glacio-marine deposits devoid of elevated mineral surfaces. We suggest that Sphagnum pools developed after peatland formation (secondary features) due to changes in water table, peat accumulation and/or climatic controls.
