Laurence M. Gould: Surface Ocean Carbon and Meteorology Measurements

NCEI Accession 0163187 contains chemical, meteorological, and physical data from the RV Laurence M. Gould's 2013 voyage in the Southern Ocean. Measurements include the partial pressure of carbon dioxide in both air and water, salinity, sea surface temperature, and barometric pressure, collected via a CO2 gas analyzer. A related dataset from 2009-2010 provides comparable surface underway observations for the same vessel and region.

Use Cases

• Calculating air-sea CO2 flux based on partial pressure measurements in air and water.
• Analyzing seasonal or spatial variability of ocean carbon parameters in the Southern Ocean.
• Correlating sea surface temperature and salinity with carbon dioxide fugacity.
• Validating or calibrating ocean carbon cycle models with in-situ underway data.

Strengths

• Data originates from a recognized research vessel (RV Laurence M. Gould) and is hosted by NOAA NCEI.
• Includes specific, high-value measurements for carbon cycle science: pCO2 in air and water, salinity, SST.
• Covers a geographically distinct and critical region: the Southern Ocean (>60°S).

Limitations

• Column names and exact data structure are not provided in any source.
• Conflicting 'last updated' dates exist (2013-12-19 vs. 2026-03-05), obscuring metadata freshness.
• Row counts and dataset sizes are uniformly listed as 'unknown' or 'None' across all platforms.
