Partial pressure (or fugacity) of carbon dioxide, pH on total scale, temperature, salinity and other variables collected from surface underway observations during the container ship Cap Blanche cruises in the Pacific Ocean from 2016-03-13 to 2016-10-19 (NCEI Accession 0158484)

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).
