[{"name":"martens-2022-arctic-terroc-1","title":"Sources and accumulation rates of terrestrial carbon in circum-Arctic shelf sediments","summary":"This dataset contains terrestrial organic carbon (terrOC) mass accumulation rates in surface sediments of the seven circum-Arctic shelf seas, observational data on relative terrOC release using the integrated carbon remobilization index (I-CRI), terrOC and marine OC source fractions in circum-Arctic shelf sediments, a data collection of mass accumulation rates in surface sediments using \u00b2\u00b9\u2070Pb-xs, as well as \u00b9\u00b3C and \u00b9\u2074C data of terrOC source compartments in the circum-Arctic drainage basin.\r\n\r\nThe dataset has been used to quantify the contribution of terrOC from different sources to circum-Arctic shelf sediments using dual-isotope (\u00b9\u00b3C and \u00b9\u2074C) source apportionment and \u00b2\u00b9\u2070Pb-xs mass accumulation rates. This work uses spatially-distributed data on \u00b9\u00b3C, \u00b9\u2074C and total OC from the Circum-Arctic Sediment Carbon Database \u2014 CASCADE.","citations":"Martens J, Wild B, Semiletov I, Dudarev OV, Gustafsson \u00d6 (2022) Circum-Arctic patterns of terrestrial carbon remobilization reveal contrasting vulnerability between regions and carbon sources.
