This dataset includes surface underway data collected from R/V Ryofu Maru III cruises in the Pacific Ocean from 2021-01-13 to 2021-10-11. These data include partial pressure of carbon dioxide in the water, barometric pressure, sea surface salinity and sea surface temperature. The instruments used to collect these data include carbon dioxide (CO2) gas analyzer, shower head chamber equilibrator for autonomous carbon dioxide (CO2) measurement.

This dataset contains data from underway fCO2 (seawater and atmospheric), ISFET-based pH (total scale), temperature, and salinity measurements collected on 4 trans-Pacific cruises in 2016 as part of a ship-of-opportunity time-series. Cruise names and expocodes: CB2016_03 (AG5W20160313), CB2016_05 (AG5W20160507), CB2016_08 (AG5W20160829), CB2016_10 (AG5W20161019). Since 1992, underway CO2 observations have been made between New Zealand and the U.S. West Coast. In 2010, ISFET-based pH measurements (total scale) were added to this equatorial Pacific SOOP-based time-series. All pH data, when available, are reported on the total scale and at SST. This effort was conducted with the support of NOAA's Ocean Observing and Monitoring Division in the Climate Program Office (CPO) and NOAA's Ocean Acidification Program (OAP).

This dataset consists of surface underway measurements of partial pressure (or fugacity) of carbon dioxide (seawater and atmospheric), ISFET-based pH (total scale), temperature, and salinity collected on 5 trans-Pacific sections during the container ship Cap Blanche ship-of-opportunity (SOOP) cruises in the Pacific Ocean from 2018-01-12 to 2018-09-04.
