P06_2010_Underway: Ocean Carbon and Surface Conditions from Cruise 318M20100105

NCEI Accession 0144244 contains high-resolution surface underway measurements from the RV Melville during a 38-day cruise in the South Pacific Ocean. The data were collected by NOAA's Atlantic Oceanographic and Meteorological Laboratory as part of the International CLIVAR Global Ocean Carbon and Repeat Hydrography Program. Measurements include the partial pressure of carbon dioxide in both air and water, enabling direct calculation of air-sea CO2 flux, alongside standard meteorological and oceanographic parameters.

Use Cases

• Calculating air-sea CO2 flux based on the measured difference in partial pressure (ΔfCO2) between the atmosphere and ocean.
• Analyzing the relationship between sea surface temperature, salinity, and carbon dioxide fugacity in the South Pacific Ocean.
• Validating and improving global carbon cycle models using direct, ship-based surface underway observations.
• Assessing changes in ocean carbon storage by comparing this 2010 data with re-occupations of the same WOCE/JGOFS hydrographic sections.

Strengths

• Data collection used specialized instruments including a Carbon dioxide (CO2) gas analyzer and a shower head chamber equilibrator.
• Covers a specific, well-documented 38-day research cruise (2010-01-05 to 2010-02-11) with a clear geographic focus (South Pacific Ocean).
• Part of a major international scientific program (CLIVAR Global Ocean Carbon and Repeat Hydrography Program) designed for systematic, comparable observations.

Limitations

• Key metadata such as row count, file size, specific column names, and license are not provided on any platform.
• Conflicting 'last updated' dates exist between platforms (2010-02-11 vs. 2026-03-05), creating uncertainty about metadata maintenance.
• The dataset's completeness and potential data gaps are not described.
