[{"name":"oden-sas-2021-expedition-metadata-1","title":"General metadata from expedition SAS, Arctic Ocean, 2021","summary":"The Synoptic Arctic Survey (SAS) 2021 expedition was carried out during summer 2021 in the Arctic Ocean, covering a large area including parts of the Amundsen Basin, Nansen Basin, North Pole area, Lomonosov Ridge, Morris Jesup Rise and Yermak Plateau.\r\n\r\nWith the Swedish icebreaker Oden serving as the research platform, a range of scientific investigations were made. The main scientific goal was to investigate the present state and ongoing transformations of the marine ecosystem.\r\n\r\nThis dataset contains all basic metadata (date, time, geographic position, water depth, etc.) for the 60 sampling stations visited and the 271 device operations (sampling procedures) performed during the expedition. All samples taken within the related OMICS programme on biodiversity and gene expression are listed as well.","citations":"Snoeijs-Leijonmalm Pauline, the SAS-Oden Scientific Party (2022) Expedition Report SWEDARCTIC: Synoptic Arctic Survey 2021 with icebreaker Oden.

The SAS field work consisted of a multinational coordinated engagement of research vessels in the summers of 2020-2022 to jointly address the Arctic Ocean. The goal of SAS is to generate an unmatched dataset that allows for a complete characterization of Arctic Ocean hydrography and circulation, organismal and ecosystem functioning and productivity, and carbon uptake and ocean acidification. The Swedish SAS-Oden 2021 expedition was organised by the Swedish Polar Research Secretariat (SPRS) in collaboration with the participating scientists. The infrastructure (ship time) was financially supported by the SPRS, the EFICA Consortium (EU) and the ARICE Consortium (EU). Within SAS, icebreaker Oden covered an area with challenging ice conditions.\r\n\r\nThe OMICS collaboration is a joint effort carried out jointly by all biological projects on-board the expedition, including sampling, deep sequencing of the samples at the [National Genomics Infrastructure (NGI)](https:\/\/www.scilifelab.se\/units\/ngi\/), SciLifeLab, Sweden, and publication of the results. The goal of this collaboration is to achieve a full metagenomic (taxonomic) and metatranscriptomic (gene expression) biodiversity record of water-column, sea ice, and sediment habitats along the expedition route. The metagenomic and metatranscriptomic datasets can later be used for exploring e.g., specific taxonomical groups, specific metabolic pathways and environmental DNA (eDNA) of invertebrates, fish, mammals and birds.\r\n\r\nSee more information about the expedition at the [Swedish Polar Research Secretariat](https:\/\/www.polar.se\/en\/expeditions\/previous-expeditions\/arctic\/synoptic-arctic-survey-2021\/).","category":"Marine","subcategory":"Expedition","keywords":"Arctic Ocean; Central Arctic Ocean; Ecosystem; Oceanography; Chemistry; Biology; Marine Geology; Food web; Communities; Fish; Squid; Zooplankton; Microbiology; Sympagic; Pelagic; Sediment; Icebreaker Oden; SAS 2021 expedition","scientist":"Pauline Snoeijs-Leijonmalm, SAS-Oden 2021 Scientific Party","firstname":"Pauline","lastname":"Snoeijs Leijonmalm","address":"Department of Ecology, Environment and Plant Sciences; Stockholm University","postalcode":"SE-106 91 ","city":"Stockholm","province":"","country":"Sweden","parameters":"Earth science > Oceans","location":"Ocean > Arctic Ocean","progress":"Completed","language":"English","project":"Synoptic Arctic Survey (SAS) 2021 expedition","publisher":"Bolin Centre Database","version":"1","constrains":"","access":""}]
