VOS_FLUPAC_1994: Surface Ocean Carbon Measurements

From September 23 to October 30, 1994, this dataset contains surface underway measurements collected aboard the vessel L'ATALANTE in the North and South Pacific Ocean. The data likely includes time-series records of barometric pressure, sea surface temperature, salinity, and the partial pressure of carbon dioxide in seawater. These measurements were gathered by researchers from institutions including the Commonwealth Scientific and Industrial Research Organization and Sorbonne University using a carbon dioxide gas analyzer.

Use Cases

• Analyzing ocean carbon uptake based on partial pressure of carbon dioxide measurements.
• Studying sea surface temperature and salinity gradients across the Pacific Ocean transect.
• Validating ocean carbon cycle models using in-situ surface underway data.
• Investigating correlations between barometric pressure and oceanic carbon dioxide fugacity.

Strengths

• Provides in-situ measurements from a specific, well-documented research cruise (VOS_FLUPAC_1994).
• Includes key variables for ocean carbon cycle research, such as carbon dioxide fugacity.
• Hosted on multiple authoritative platforms (Data.gov, NASA Earthdata), indicating vetting and persistence.

Limitations

• Metadata completeness is low: column names, row count, file size, and license are not specified in any source.
• Sources provide conflicting author affiliations (e.g., R. Le Borgne's affiliation is listed as both '[unknown]' and 'IRD').
• The dataset is from a single, short time period in 1994, limiting analysis of long-term trends.
