[{"name":"oden-sas-2021-fish-otoliths-1","title":"Fish otoliths in sediment samples from expedition SAS, Arctic Ocean, 2021","summary":"This dataset contains metadata and 296 files with photographs of 325 fish otoliths (calcium carbonate structures in the heads of bony fishes) sampled from the Arctic Ocean.\r\n\r\nThe otoliths were sampled from the upper 15 cm sediment layer during the Synoptic Arctic Survey (SAS) 2021 expedition with the Swedish icebreaker Oden serving as the research platform. The sediments were collected at 713\u2060\u200a\u2013\u200a\u20601537 m of water depth from eight 50 x 50 cm box-cores taken at six sampling stations.\r\n\r\nThese otoliths can be used for reconstructing fish occurrence in the Central Arctic Ocean and above the Morris Jesup Rise and Yermak Plateau during the last 50,000 years. Radiocarbon dating of 90 otoliths showed that the otoliths were deposited in the sediments during the Holocene (ca. 11.7\u2060\u200a\u2013\u200a\u20600 ka BP), the Last Glacial Maximum (ca. 29\u2060\u200a\u2013\u200a\u206011.7 ka BP) and the final stage of the Last Glacial Period (ca. 29\u2060\u200a\u2013\u200a\u206057 ka BP).","citations":"Snoeijs-Leijonmalm Pauline, the SAS-Oden Scientific Party (2022) Expedition Report SWEDARCTIC: Synoptic Arctic Survey 2021 with icebreaker Oden.
