This dataset includes surface underway, chemical, meteorological and physical data collected from R/V Oden Synoptic Arctic Survey 2021 cruise (EXPOCODE 77DN20210802) in the Arctic Ocean from 2021-08-02 to 2021-09-11. These data include water temperature, barometric pressure, partial pressure (or fugacity) of carbon dioxide - atmosphere, partial pressure (or fugacity) of carbon dioxide - water. Research expedition to central Arctic Ocean onboard Icebreaker Oden. https://www.polar.se/en/expeditions/previous-expeditions/arctic/synoptic-arctic-survey-2021/. During an ice camp close to the North Pole, The pCO2 system was deployed from a temporary mooring in a lead adjacent to the ice floe to which Oden was moored, approximately 1.5 km from Oden's position. The sensor was positioned approx 2 m from the ice edge and drew water through a pumped intake at 0.5 m depth. Abstract

This dataset includes the profile discrete measurements of dissolved inorganic carbon, total alkalinity, CTD salinity and temperature collected in the summer of 2010 aboard R/V Xuelong in the Chinese Arctic Research Expedition (CHINARE10) cruise. The CHINARE project is an international collaboration between U.S. and Chinese scientists to study the water column carbonate chemistry in the western Arctic Ocean and Chukchi Sea.

This dataset includes the profile discrete measurements of dissolved inorganic carbon, total alkalinity, CTD salinity and temperature collected during the R/V Xuelong CHINARE2008 cruise (EXPOCODE 76XL20080730) in the Arctic Ocean, Chukchi Sea from 2008-07-30 to 2008-09-11. The CHINARE project is an international collaboration between U.S. and Chinese scientists to study the water column carbonate chemistry in the western Arctic Ocean and Bering Sea.

This dataset includes profile discrete measurements of dissolved inorganic carbon, total alkalinity, pH on total scale, temperature, salinity, oxygen and CFCs obtained during R/V Oden Lomonosov Ridge off Greenland (LOMROG) expedition (EXPOCODE 77DN20070812) in the Arctic Ocean from 2007-08-12 to 2007-09-19. The R/V Oden expedition is the oceanographic component of LOMROG focuses on constraining and understanding the pathways of the Atlantic water and deep water across the Lomonosov Ridge between the Eurasian Basin and Canadian Basin and through the western Fram Strait.

This dataset includes discrete profile measurements of dissolved inorganic carbon (DIC), total alkalinity, water temperature, salinity, dissolved oxygen, nutrients and other hydrographic and chemical data collected from discrete samples and profile observations during the CCGS Louis S. St-Laurent Joint Ocean Ice Study (JOIS-13) cruise (EXPOCODE 18SN20130724) in the Arctic Ocean, Beaufort Sea, Davis Strait and Northwestern Passages from 2013-07-24 to 2013-09-02. The Joint Ocean Ice Study (JOIS) in 2013 is an important contribution from Fisheries and Oceans Canada to international Arctic climate research programs. Primarily, it involves the collaboration of Fisheries and Oceans Canada researchers with colleagues in the USA from Woods Hole Oceanographic Institution (WHOI). The scientists from WHOI lead the Beaufort Gyre Exploration Project (BGEP) and the Beaufort Gyre Observing System (BGOS) which forms part of the Arctic Observing Network (AON).

This dataset includes discrete profile measurements of dissolved inorganic carbon (DIC), total alkalinity, pH on total scale, water temperature and salinity, oxygen, nutrients and other parameters measured onboard the R/V Polarstern, ARK XXVI_3; TransArc cruise (EXPOCODE 06AQ20110805) in the central Arctic Ocean from 2011-08-05 to 2011-10-07.

St-Laurent Joint Ocean Ice Study (JOIS-10) cruise (EXPOCODE 18SN20100915) in the Arctic Ocean from 2010-09-15 to 2010-10-15. The Joint Ocean Ice Study (JOIS) in 2010 involved the collaboration of Fisheries and Oceans Canada researchers with colleagues primarily from the U.S.A and Japan. This program forms an important Canadian contribution to international climate research programs and is comprised of two ongoing programs: the Beaufort Gyre Exploration Project (BGEP), a collaboration with Woods Hole Oceanographic Institution scientists and the Pan-Arctic Climate Investigation (PACI), a collaboration with Japan Agency for Marine-Earth Science and Technology (JAMSTEC) scientists. In 2010 JOIS also included ancillary programs carried out by researchers from: the International Arctic Research Center (IARC) in Fairbanks Alaska; Tokyo University of Marine Science and Technology (TUMSAT), Japan; Kitami Institute of Technology (KIT), Japan.
