This dataset includes Surface underway, chemical, meteorological and physical data collected from JOHN P. TULLY, PARIZEAU, QUADRA and VANCOUVER in the Arctic Ocean, Beaufort Sea, Bering Sea, Coastal Waters of Southeast Alaska and British Columbia, Gulf of Alaska, Japan Sea, North Pacific Ocean, Olympic Coast National Marine Sanctuary and Sea of Okhotsk from 1973-08-12 to 2003-09-13. These data include ABSOLUTE HUMIDITY, AIR TEMPERATURE - DRY BULB, AIR TEMPERATURE - WET BULB, BAROMETRIC PRESSURE, Partial pressure (or fugacity) of carbon dioxide - atmosphere, Partial pressure (or fugacity) of carbon dioxide - water, SALINITY and SEA SURFACE TEMPERATURE. The instruments used to collect these data include Carbon dioxide (CO2) gas analyzer. These data were collected by C. S. Wong and Sophia C. Johannessen of Fisheries and Oceans Canada; Institute of Ocean Sciences as part of the Station P, Line P dataset. CDIAC associated the following cruise ID(s) with this dataset: Line P and Station P

As part of a multi-year effort to quantify the flux of CO2 between the ocean and atmosphere, the Ocean Climate Observation Program of the National Oceanic and Atmospheric Administration (NOAA) supports the deployment of underway CO2 systems on NOAA research ships and volunteer observing ships (VOS) in the Atlantic and Pacific Oceans. The CO2 group of NOAA's Pacific Marine Environmental Laboratory (PMEL) has been monitoring sea surface CO2 concentrations in the equatorial Pacific since 1982. This is a particularly dynamic area exhibiting significant variation of CO2 concentrations, both interannually due to the effect of periodic El Niño events, and seasonally due to the changes in wind strength and upwelling patterns. By measuring the pCO2 in both the sea surface and atmosphere, along with sea surface temperature, pressure, and wind speed, the flux of CO2 can be calculated, affording a broader understanding of key processes and changes in these processes in the ocean on decadal time scales. A strong upwelled-driven inverse pCO2-SST relationship exists across the equatorial Pacific, allowing the development of an empirical approach to obtain highly resolved pCO2 distributions and CO2 fluxes. This data package represents pCO2 gathered by PMEL onboard VOS container ships from 2004 through 2018. The cruises during the 15-year period included 63 transects of the Pacific Ocean between the North Pacific West Coast and New Zealand/Australia.

This data package represents pCO2 gathered by PMEL onboard the NOAA Ka'imimoana from 1996 through 2010 as a companion project to the biannual servicing of the Tropical Atmosphere Ocean (TAO) Array moorings. The cruises during the 15-year period included 77 transects of the equatorial Pacific between 95°W and 165°E, and spanned several El Niño events.

This dataset includes carbon dioxide, temperature, salinity, and other variables collected via surface underway survey from Volunteer Observing Ship Almirante Irizar in the South Atlantic Ocean and SW Atlantic from 2000-03-24 to 2005-04-12.

This dataset contains two improved surface pCO2 products, along with surface pCO2 from the INCOIS-BIO-ROMS model (pCO2_model) and other input variables. It is a long-term, high-resolution dataset developed for the Indian Ocean region (30°E - 120°E, 30°S - 30°N), covering the period from 1980 to 2019. The dataset features a monthly temporal resolution and a spatial resolution of 1/12°. The file includes INCOIS-BIO-ROMS model outputs (sea surface temperature (SST), sea surface salinity (SSS), mixed layer depth (MLD), nitrate (NO3), dissolved inorganic carbon (DIC), and chlorophyll-a (CHL)). These variables are used as inputs for machine learning models to improve the pCO2_model. The machine learning model predicts the surface pCO2 deviants (pCO2_obs - pCO2_model). The file also provides spatiotemporally varying uncertainties associated with the predicted pCO2 deviants.

This dataset includes chemical, meteorological, physical and time series data collected from mooring JKEO_147E_38N in the North Pacific Ocean from 2007-02-18 to 2007-10-03. These data include air-sea difference - partial pressure of carbon dioxide (pCO2), barometric pressure, oxygen, pCO2 - atmosphere, pCO2 - water, salinity and sea surface temperature. The Moored Autonomous pCO2 (MAPCO2®) instruments used to collect these data include Bubble type equilibrator for autonomous carbon dioxide (CO2) measurement, Carbon dioxide (CO2) gas analyzer, Humidity Sensor, and oxygen meter. The Global CO2 Time-series and Moorings Project involves international groups from 18 countries who have mounted sensors on moored buoys to provide high resolution time-series measurements of atmospheric boundary layer and surface ocean CO2 partial pressure (pCO2). The CO2 Time-series and Moorings Project is coordinated by UNESCO International Ocean Carbon Coordination Project (IOCCP).
