Laurence M. Gould Surface Underway Carbon and Ocean Data

Surface underway data from the RV Laurence M. Gould covers the North Pacific, South Atlantic, South Pacific, and Southern Oceans. It includes measurements of the partial pressure of carbon dioxide in air and water, salinity, sea surface temperature, and barometric pressure collected during cruises from 2004 to 2009. The dataset supports research on ocean carbon cycling and air-sea gas exchange.

Use Cases

• Calculating air-sea CO2 flux based on simultaneous atmospheric and aquatic partial pressure measurements.
• Analyzing correlations between sea surface temperature and carbon dioxide fugacity in water.
• Studying spatial and temporal variability of surface ocean salinity across major ocean basins.
• Validating and calibrating ocean carbon cycle models with in-situ underway observations.

Strengths

• Data collected across multiple major ocean basins, including the remote Southern Ocean.
• Includes concurrent atmospheric and aquatic carbon dioxide measurements, enabling flux calculations.
• Time series spans multiple years, with specific cruise data from 2004-2005 and 2008-2009.

Limitations

• Conflicting time ranges exist between sources (2004-2005 vs. 2008-2009), creating ambiguity about the exact temporal coverage.
• Column names and precise row counts are not provided in any source, limiting understanding of data structure.
• Metadata for license, author, and exact data size is consistently listed as unknown or null.
