Popis: This special issue comprising 14 articles emerged from the PAGES supported meeting: Holocene Circum Arctic Peatland Carbon Dynamics Community Wide Data Synthesis and Modeling Initiatives which took place from the 12 16 October 2013 in Bethlehem Pennsylvania. It is a precursor product of PAGES' C PEAT Working Group. ABSTRACT: Here we present results from the most comprehensive compilation of Holocene peat soil properties with associated carbon and nitrogen accumulation rates for northern peatlands. Our database consists of 268 peat cores from 215 sites located north of 45°N. It encompasses regions within which peat carbon data have only recently become available such as the West Siberia Lowlands the Hudson Bay Lowlands Kamchatka in Far East Russia and the Tibetan Plateau. For all northern peatlands carbon content in organic matter was estimated at 42 ± 3 (standard deviation) for Sphagnum peat 51 ± 2 for non Sphagnum peat and at 49 ± 2 overall. Dry bulk density averaged 0.12 ± 0.07 g/cm3 organic matter bulk density averaged 0.11 ± 0.05 g/cm3 and total carbon content in peat averaged 47 ± 6. In general large differences were found between Sphagnum and non Sphagnum peat types in terms of peat properties. Time weighted peat carbon accumulation rates averaged 23 ± 2 (standard error of mean) g C/m2/yr during the Holocene on the basis of 151 peat cores from 127 sites with the highest rates of carbon accumulation (25–28 g C/m2/yr) recorded during the early Holocene when the climate was warmer than the present. Furthermore we estimate the northern peatland carbon and nitrogen pools at 436 and 10 gigatons respectively. The database is publicly available at https://peatlands.lehigh.edu.
