Laurence M. Gould: Southern Ocean Carbon Dioxide and Sea Surface Measurements (2002-2003)

Surface underway data from the RV Laurence M. Gould includes measurements of barometric pressure, partial pressure of carbon dioxide in air and water, salinity, and sea surface temperature. The data were collected across the South Atlantic, South Pacific, and Southern Oceans (>60°S) over multiple cruises spanning from 2002-03-07 to 2003-12-29. Instruments used include a carbon dioxide gas analyzer and a shower head chamber equilibrator for autonomous CO2 measurement.

Use Cases

• Calculating air-sea CO2 flux based on partial pressure measurements in the atmosphere and water.
• Analyzing seasonal variability of sea surface temperature and salinity in the Southern Ocean.
• Calibrating or validating autonomous carbon dioxide measurement systems and methodologies.
• Studying correlations between barometric pressure and oceanic carbon dioxide concentrations.

Strengths

• Data collection spans multiple years (2002-2003) and multiple distinct research cruises.
• Includes directly measured, co-located variables (CO2 partial pressure, SST, salinity, barometric pressure) critical for flux calculations.
• Associated with specific, documented cruise IDs (e.g., 33LG20030101) and principal investigators from recognized institutions.

Limitations

• Column names and exact data structure are not provided in the available metadata.
• Exact row counts and file sizes are unknown for all described accessions.
• Conflicting temporal coverage is noted between sources (e.g., 2003-01-01 to 2003-12-29 vs. 2002-12-29 to 2003-11-30).
