The sediment cores were collected from the Chukchi Sea, Arctic Ocean during the SWERUS-C3 (Leg 2) Expedition in 2014 with Swedish icebreaker Oden.\r\n\r\nAge models for the cores are based on radiocarbon dates, cesium-137 and mercury isochrons, and a tephra layer from the Aniakchak CFE II eruption (~3.6 ka ago).\r\n\r\nThe dataset contains Hg concentration, radiometric activity profiles of \u00b9\u00b3\u2077Cs, \u00b2\u2074\u00b9Am, \u00b2\u00b9\u2070Pb, selected paleo- and rock magnetic data from sediment cores SWERUS-L2-2-PC1 and SWERUS-L2-4-PC1, and the results of a multi-parameter synchronisation of the two records.\r\n\r\n\r\n\r\n","citations":"West G, Nilsson A, Geels A, Jakobsson M, Moros M, Muschitiello F, Pearce C, Snowball I, O'Regan M (in review) Late Holocene paleomagnetic secular variation in the Chukchi Sea, Arctic Ocean.","comments":"Coordinates of the coring sites:\r\n- 2-PC1: 72.51658\u00b0 N, 175.3196\u00b0 W\r\n- 4-PC1: 72.83833\u00b0 N, 175.7267\u00b0 W\r\n\r\nMore information about the [SWERUS-C3 expedition](https:\/\/polarforskningsportalen.se\/en\/arctic\/expeditions\/swerus-c3) is available from the Swedish Polar Research Secretariat.
