[{"title":"Age model and physical properties of sediment from the Arctic Siberian margin, core SWERUS-L2-31PC","summary":"Age model and sedimentological data for a marine sediment core collected on the Lomonosov Ridge adjoining the East Siberian shelf, Arctic Ocean. The dataset includes porosity, magnetic susceptibility and organic carbon content measured at 1 cm intervals.\r\n\r\nA 30,000 year age-depth model for the core is also provided. This is required to convert sediment depth to age. The age model is needed to generate meaningful time series on environmental changes in this region of the Arctic using other analytical approaches, and will therefore underpin future work on this sediment core. \r\n\r\nThe core was collected during the SWERUS-C3 expedition to the Arctic Ocean with the Swedish icebreaker Oden in 2014.","citations":"Muschitiello F, O'Regan M, Martens J, West G, Gustafsson \u00d6, Jakobsson M.
