This dataset includes discrete profile measurements of total alkalinity, pH on total scale, water temperature, salinity, silicate, nitrate, phosphate, delta C13, and other measurements collected during the CCGS Amundsen GEOTRACES cruise ArcticNet1503 (EXPOCODE 18DL20150905) in the Arctic Ocean and Northwestern Passages from 2015-09-05 to 2015-10-01.

This dataset consists of discrete samples and profile observations collected during the R/V S.A. Agulhas I National Centre for Polar and Ocean Research (NCPOR) cruise (EXPOCODE 91AA20171209) in the Indian Ocean from 2017-12-09 to 2018-02-04. These data include total alkalinity, pH on total scale, temperature, salinity, oxygen, nutrients and ammonia measurements. The NCAOR cruise is the part of the Southern Ocean Carbon and Climate Observations and Modeling project (SOCCOM) cruises and the Antarctic resupply cruise SOE2017-18 in South West Indian Ocean.

This dataset includes discrete sample and profile data collected during the ArcticNet CCGS Amundsen cruises AMU2016-02, AMU2017-02, and AMD1802 (EXPOCODEs 18DL20160716, 18DL20170714, 18DL20180725) as part of the HiBio project in Baffin Bay and Davis Strait from 2016-07-16 to 2018-08-13. These data include dissolved inorganic carbon (DIC), total alkalinity (TA), partial pressure of CO2 (pCO2), methane, dissolved oxygen, water temperature, salinity and other measurements. As a part of the ArcticNet program; the "HiBio" project investigated the distribution of benthic organisms; particularly cold water corals and sponges. State of the ocean acidification was studied to understand the environment for these habitats in Davis Strait and Baffin Bay region.

This dataset includes discrete, profile measurements of dissolved inorganic carbon (DIC), total alkalinity, water temperature and salinity, measured during the Canadian Coast Guard Ship Amundsen Fisheries and Oceans Canada ArcticNET (NSERC) cruise AN1103 (EXPOCODE 18DL20111006) in the Eastern Canadian Arctic, Baffin Bay, Northwestern Passages from 2011-10-06 to 2011-10-21.

This dataset contains seawater biogeochemical measurements of the inorganic carbon system (dissolved inorganic carbon and total alkalinity), stable oxygen isotope ratios of seawater (𝛿18O), salinity measured on a benchtop salinometer, nutrient concentrations (silicate, phosphate, nitrate, nitrite, and ammonium), as well as CTD measurements (salinity, temperature, pressure), and oxygen concentration measurements from a probe (SBE-43). The measurements were collected during Leg 2 of the 2019 research cruise of the CCGS Amundsen throughout Baffin Bay, Lancaster Sound, and Nares Strait (eastern Canadian Arctic).

This dataset includes chemical, discrete sample, physical and profile data collected from ODEN in the Arctic Ocean from 2001-07-17 to 2001-07-26 and retrieved during cruise CARINA/77DN20010717. These data include ALKALINITY, HYDROSTATIC PRESSURE, Potential temperature (theta), SALINITY and WATER TEMPERATURE. The instruments used to collect these data include CTD and bottle. These data were collected by Leif G. Anderson of University of Gothenburg (GU) as part of the CARINA/77DN20010717 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 sample and profile data collected during the R/V Sarmiento de Gamboa cruise CAIBOX (EXPOCODE 29AH20090725) in the North Atlantic Ocean from 2009-07-25 to 2009-08-13. These data include total alkalinity, pH on total scale, water temperature, salinity, dissolved oxygen concentration, silicate, phosphate and nitrate. The instruments used to collect these data include Alkalinity titrator, CTD, Niskin bottles and spectrophotometer. These data were collected by AÃda F. RÃos, Fiz F. Pérez, and Miguel Gilcoto of Institute of Marine Research Vigo (IIM) as part of the CLIVAR_CAIBOX_2009 dataset. The International CLIVAR Global Ocean Carbon and Repeat Hydrography Program carries out a systematic and global re-occupation of select WOCE/JGOFS hydrographic sections to quantify changes in storage and transport of heat, fresh water, carbon dioxide (CO2), and related parameters.

This dataset includes hydrographic and chemical data collected from discrete samples and profile observations from United States Coast Guard Cutter (USCGC) Healy cruise HLY1103 (EXPOCODE 33HQ20111003) in the Arctic Ocean, Beaufort Sea and Northwestern Passages from 2011-10-03 to 2011-10-27. These data include Total alkalinity, pH on total scale, water temperature, salinity and dissolved oxygen concentration. The instruments used to collect these data include CTD and Niskin bottles. These data were collected by Jeremy T. Mathis of NOAA Pacific Marine Environmental Laboratory (PMEL) and Natalie M. Monacci of University of Alaska - Fairbanks (UAF) as part of the CLIVAR_HLY1103 dataset. The International CLIVAR Global Ocean Carbon and Repeat Hydrography Program carries out a systematic and global re-occupation of select WOCE/JGOFS hydrographic sections to quantify changes in storage and transport of heat, fresh water, carbon dioxide (CO2), and related parameters.
