This dataset contains data from underway fCO2 (seawater and atmospheric), temperature, and salinity measurements collected on 4 trans-Pacific cruises in 2015 as part of a ship-of-opportunity time-series. Cruise names and expocodes: CB2015_03 (AG5W20150328), CB2015_05 (AG5W20150524), CB2015_09 (AG5W20150930), CB2015_11 (AG5W20151120). Since 1992, underway CO2 observations have been made between New Zealand and the U.S. West Coast. 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).
