Oceanographic sampling of physical, chemical, and biological parameters was conducted along selected fixed sections in Davis Strait, Baffin Bay, northern Labrador Sea, North Atlantic Ocean at full water depths during the R/V Neil Armstrong Davis Strait Observing System (DSOS) cruise "AR69-04" (EXPOCODE 33VB20221001) from 2022-10-01 to 2022-10-22. The cruise is part of DSOS's long-term, high-frequency repeat program. CTD casts were performed at all stations, and discrete water samples were collected in Niskin bottles using the CTD/Rosette system. The cruise was designed to investigate Arctic-North Atlantic interactions, including the variability and trend of freshwater, heat, carbon, oxygen, and nutrient fluxes, as well as ecosystem responses to climate change. This effort was conducted in support of the NSF (OPP1902595) and Fisheries and Oceans, Canada (OFSI).

This dataset includes discrete profile measurements of dissolved inorganic carbon (DIC), total alkalinity (TA), water temperature, salinity, dissolved oxygen, macronutrients, and oxygen isotopes measured during R/V Rachel Carson cruise RC0083 in the the Gulf of Alaska from 2022-08-11 to 2022-08-24. The cruise was funded by the National Oceanic and Atmospheric Administration (NOAA) Ocean Acidification Program (OAP). The carbonate system data were collected and analyzed by members at the Ocean Acidification Research Center (OARC) at the University of Alaska Fairbanks (UAF). The dissolved oxygen and macronutrient samples were analyzed by Calvin Mordy's group at UW CICOES and NOAA PMEL. The oxygen stable isotopes were analyzed at the Oregon State University Stable Isotope Lab. CTD operations were led by the chief scientist, Jessica Cross, and the ship's crew.

This dataset includes chemical, discrete sample, physical and profile data collected from LOUIS S. ST. LAURENT in the Baffin Bay, Davis Strait, Hudson Strait and Northwest Passage from 1997-08-03 to 1997-08-18 and retrieved during cruise CARINA/18SN19970803 (18SNA097, JOIS 97 and Leg 1). These data include ALKALINITY, CHLOROFLUOROCARBON-11 (CFC-11), CHLOROFLUOROCARBON-113 (CFC-113), CHLOROFLUOROCARBON-12 (CFC-12), Carbon tetrachloride (CCL4), DISSOLVED INORGANIC CARBON, DISSOLVED OXYGEN, HYDROSTATIC PRESSURE, NITRATE, NITRITE, PHOSPHATE, Potential temperature (theta), SALINITY, SILICATE and WATER TEMPERATURE. The instruments used to collect these data include CTD and bottle. These data were collected by E. Peter Jones and Kumiko Azetsu-Scott of Bedford Institute of Oceanography (BIO), Fiona McLaughlin of Fisheries and Oceans Canada, Institute of Ocean Sciences, and Kelly K. Falkner of Oregon State CEOAS (OSU-CEOAS) as part of the CARINA/18SN19970803 dataset. The CARINA (CARbon dioxide IN the Atlantic Ocean) data synthesis project is an international collaborative effort of the EU IP CARBOOCEAN, and U.S. partners. It has produced a merged internally consistent dataset of open ocean subsurface measurements for biogeochemical investigations, in particular, studies involving the carbon system. The original focus area was the North Atlantic Ocean, but over time the geographic extent expanded and CARINA now includes data from the entire Atlantic, the Arctic Ocean, and the Southern Ocean.

This dataset includes discrete profile measurements of dissolved inorganic carbon (DIC), total alkalinity, pH on total scale, temperature, salinity, oxygen and nutrients collected during the R/V Keifu Maru II cruise ks201706, Repeat Hydrography Sections P09, P10 (EXPOCODE 49UF20170719) in the North Pacific Ocean from 2017-07-19 to 2017-09-07.

This dataset contains discrete profile measurements of dissolved inorganic carbon (DIC), total alkalinity, pH on total scale, water temperature, salinity, dissolved oxygen concentration, nutrients and other chemical and hydrographic parameters obtained during the R/V Sarmiento de Gamboa RADPROF 2020 cruise (EXPOCODE 29AH20200710) in the North East Atlantic Ocean from 2020-07-08 to 2020-07-22 The RADPROF project is an annual routine monitoring activity associated with the Finisterre deep section, RADPROF, which contributes to the IEO oceanography observation system, IEOOS since 2003. RADPROF contributes to time series of hydrography, circulation, inorganic biogeochemistry and biology in the slope region of the Galicia-Cantabrian region, passing through the protected area of the Bank of Galicia since 2014. The time series began in 2003 with the VACLAN National Plan project, continued by COVACLAN (2005) and later integrated as a structural program of the IEO under the pseudonym RADPROF. The basic activity is reinforced and expanded thanks to competitive projects of the National Plan such as MODUPLAN (2014), or Interreg EU iFADO (2020), complementary sampling activities using gliders (FinisGlider). Currently RADPROF is basic in Chapter 6 of the Marine Strategy Framework Directive, as it also would be for the Ocean Acidification and Prevailing Conditions chapter. From 2024 to 2026 it will contribute to the EuroGOSHIP project in support of the improvement of European hydrography. RADPROF is recognized as a GO-SHIP Associated line due to the high density and quality of its thermohaline, circulation and inorganic biogeochemistry data, especially CO2 variables.

This dataset includes discrete sample and profile data collected during Fisheries and Oceans Canada CCGS Needler cruise NED2015017 (EXPOCODE 18NE20150629) in the Bay of Fundy from 2015-06-29 to 2015-08-17. The data include measurements of Dissolved inorganic carbon (DIC), total alkalinity (TA), nutrients, pigments, dissolved oxygen, temperature, salinity and other measurements. Oceanographic sampling of physical; biological and chemical parameters is performed biweekly at selected fixed stations and two to three times annually along selected fixed sections; as part of the Atlantic Zone Monitoring Program. The sampling consists at minimum of vertical profile of the entire water column; water bottle sampling at selected depths of nutrients; salinity and oxygen; vertical net tows for zooplankton and Secchi depth measurement.

This dataset consists of data collected during the CCGS John P. Tully cruise 2019.23 (EXPOCODE 18DD20190829) in the Salish Sea and off the west coast of Vancouver Island of the North American Pacific coast from 2019-08-29 to 2019-09-06 as part of the La Perouse Water Properties Survey. Discrete dissolved inorganic carbon (DIC), total alkalinity (TA), salinity, and nutrient samples were taken from rosette casts with 10L Niskin bottles and analysed at the Institute of Ocean Sciences. Discrete samples of dissolved oxygen were also collected and analysed onboard the vessel. CTD profiles were recorded with each rosette cast. DIC and TA samples were placed in cold storage for 1-4 weeks before analysis. A total of 61 DIC and TA pairs were sampled with a 22 percent replication rate. Replicates are not averaged in this dataset and appear individually, indicated by decimal sample ID's (e.g. 26.1, 26.2). The pooled standard deviations (of difference between replicate pairs) were calculated to be 6 umol/kg and 5 umol/kg respectively. Replicates with a QC flag = 3 were included in the pooled standard deviation calculation but replicate pairs with at least one QC flag = 4 (n = 1) were excluded.
