GO-SHIP P02: Underway Carbon Dioxide Measurements in the North Pacific

From March 21 to June 1, 2013, this dataset contains underway measurements of partial pressure and fugacity of carbon dioxide (pCO2/fCO2), sea surface salinity, and temperature collected during two R/V Melville cruises along the GO-SHIP Section P02. The cruises transited the North Pacific Ocean from Yokohama, Japan, to San Diego, CA. The data supports research into ocean acidification and carbon cycling as part of the Global Ocean Ship-Based Hydrographic Investigations Program and NOAA's Climate Program Office.

Use Cases

• Analyzing spatial gradients of surface ocean pCO2 along a major Pacific transect.
• Investigating ocean acidification trends based on fugacity of carbon dioxide (fCO2) measurements.
• Validating ocean carbon models using underway sea surface temperature and salinity data.
• Studying air-sea carbon dioxide exchange using interpolated xCO2 measurements.

Strengths

• Covers a specific, well-defined research cruise track (GO-SHIP Section P02) with precise temporal bounds.
• Includes multiple directly measured parameters (pCO2/fCO2, SST, salinity) relevant for carbon cycle studies.
• Data is associated with a major international oceanographic program (GO-SHIP) and NOAA's Climate Program Office.

Limitations

• Column names and data structure are not explicitly listed in the provided metadata.
• Metadata conflicts exist: one platform shows a last update in 2026, while another shows the data collection end date in 2013.
• The exact size (row count) and file format details beyond 'HTML' are unknown.
