Partial pressure and fugacity of carbon dioxide (pCO2/fCO2), temperature, salinity and other variables collected from surface underway observations using shower head equilibrator, carbon dioxide gas detector and other instruments during the R/V Melville cruises MV1305 (EXPOCODE 318M20130321) and MV1306 (EXPOCODE 318M20130508) along the Global Ocean Ship-Based Hydrographic Investigations Program (GO-SHIP) Section P02 in the North Pacific Ocean from 2013-03-21 to 2013-06-01 (NCEI Accession 0200367)

This NCEI Accession contains underway measurements of partial pressure and fugacity of carbon dioxide (pCO2/fCO2), sea surface salinity, sea surface temperature, and other parameters collected during the R/V Melville cruises MV1305 (EXPOCODE 318M20130321) and MV1306 (EXPOCODE 318M20130508) along the Global Ocean Ship-Based Hydrographic Investigations Program (GO-SHIP) Section P02 in the North Pacific Ocean from 2013-03-21 to 2013-06-01. The cruises started in Yokohama, Japan and ended in San Diego, CA. This effort was conducted in support of the Global Ocean Ship-Based Hydrographic Investigations Program (GO-SHIP) and NOAA's Climate Program Office (CPO).
