“…For ombrotrophic peatlands, mean accumulation rates have been estimated for various countries such as of Iceland (0.40 mm.yr -1 ), Estonia (0.49 mm.yr -1 ), Norway (0.18 mm.yr -1 ), Finland (0.52 mm.yr -1 ), Canada (0.48 -0.50 mm.yr -1 ) and Spain (0.36-0.47 mm.yr -1 ) (Everett 1983;Gorham, 1991;Mäkilä, 1997;Pontevedra-Pombal, et al, 2017). Peat accumulation rates as high as one centimeter per decade have also been reported in a few European peatlands (Hughes et al, 2000;Malmer and Wallén, 2004;Langdon and Barber, 2005;Pontevedra-Pombal et al, 2018).…”

“…The bog mesotope at Cercio, considered to be intermediate between saddle raised bog and blanket bog saddle mire unit, is surrounded by fen on all sides and forms an unusual component of the larger blanket mire complex and is perhaps a unique type of landform in Spanish blanket bogs; in fact, another raised bog with similar characteristics can be found in Galicia (e.g. Chao de Veiga Mol), although in this case this peatland has been described as an 'intact' raised bog with up to 915cm of peat (Pontevedra-Pombal et al, 2019). Interpretation of the unit as intermediate form is based on current morphology, but it should be noted that the area is under high anthropogenic pressures, which may have altered the 'natural' morphology and context of this mire system.…”

Blanket bogs are a globally rare type of ombrotrophic peatland internationally recognized for long‐term terrestrial carbon storage, the potential to serve as carbon sinks, habitat provision and for their palaeoenvironmental archive. This habitat is protected in the European Union under the Habitats Directive (92/43/EEC), but a number of blanket bogs located in the Cantabrian Mountains (northern Spain), representing the southernmost known edge‐of‐range for this habitat in Europe, are currently not recognized and are at increased threat of loss. Using climatic data, topography, aerial photography and peat depth surveys, this study has identified 10 new areas of blanket bog located between the administrative regions of Cantabria and Castilla y León. Peat depth data and topography were used to provide a detailed geomorphological description and hydromorphological classification (mesotope units) of these currently unrecognized areas of blanket bog. Maximum peat depth measured across the 10 sites ranged from 1.61 to 3.78 m, covering a total area of 18.6 ha of blanket bog (>40 cm peat depth). The volume of peat accumulated across the sites was determined to be more than 216 000 m3 and is estimated to hold 19.89 ± 3.51 kt C. Twenty‐four individual hydrological mesotope units were described, indicating a diverse assemblage of blanket bogs in this region. The peatlands identified in this research extend the known limit of blanket bogs in Europe farther south than previously recorded and – combined with four other unprotected blanket bogs recently identified in the Cantabrian Mountains – these peatlands represent 10.5% of blanket bog currently recognized and protected in Spain. The range of anthropogenic pressures currently acting on peatlands in the Cantabrian Mountains indicates that without protection these important landforms and stored carbon may be lost. An urgent update of European peatland inventories is thus required to preserve these valuable carbon stores and potential carbon sinks. © 2020 The Authors.

“…By assuming a relatively constant rate of peat deposition, similar to modern rates of high latitude peat accumulation 12,23 , with peat-to-coal compaction ratios sourced from literature 22,24–26 , a range of potential time scales for each δ 13 C cycle may be calculated (Table 1).…”

“…Despite coal occurrence recording the high rates of carbon burial during this period, high-resolution δ 13 C org records of coals deposited during the LPIA have not yet been used to demonstrate changes in the global carbon cycle. The slow accumulation of peat, ~0.9 mm/yr in modern high-latitude settings 12 , allows subsequently formed coals to continuously record palaeoclimate and palaeoenvironmental change at high-temporal resolutions.…”

The end of the Late Palaeozoic Ice Age (LPIA) ushered in a period of significant change in Earth’s carbon cycle, demonstrated by the widespread occurrence of coals worldwide. In this study, we present stratigraphically constrained organic stable carbon isotope (δ13Corg) data for Early Permian coals (312 vitrain samples) from the Moatize Basin, Mozambique, which record the transition from global icehouse to greenhouse conditions. These coals exhibit a three-stage evolution in atmospheric δ13C from the Artinskian to the Kungurian. Early Kungurian coals effectively record the presence of the short-lived Kungurian Carbon Isotopic Excursion (KCIE), associated with the proposed rapid release of methane clathrates during deglaciation at the terminus of the Late Palaeozoic Ice Age (LPIA), with no observed disruption to peat-forming and terrestrial plant communities. δ13Corg variations in coals from the Moatize Basin are cyclic in nature on the order of 103–105 years and reflect changes in δ13Corg of ~±1‰ during periods of stable peat accumulation, supporting observations from Palaeozoic coals elsewhere. These cyclic variations express palaeoenvironmental factors constraining peat growth and deposition, associated with changes in base level. This study also demonstrates the effectiveness of vitrain in coal as a geochemical tool for recording global atmospheric change during the Late Palaeozoic.
