NCEI 0157354: Ocean Carbon and Surface Data from RV Tangaroa, 2013

From February 2 to December 2, 2013, this dataset contains surface underway measurements from the RV Tangaroa across the Indian Ocean, South Pacific Ocean, Southern Oceans, and Tasman Sea. It includes the partial pressure of carbon dioxide in both the atmosphere and seawater, salinity, sea surface temperature, and barometric pressure, collected using a CO2 gas analyzer. The data were gathered by Dr. Kim I Currie of NIWA as part of nine distinct research cruises.

Use Cases

• Calculating air-sea CO2 flux based on the difference in partial pressure between the atmosphere and water.
• Analyzing regional ocean acidification trends using in-situ pCO2 water measurements.
• Correlating sea surface temperature and salinity with carbon dioxide concentrations.
• Validating and calibrating satellite-derived ocean carbon models with ship-based underway data.

Strengths

• Provides a continuous ten-month time series of surface ocean carbon measurements from 2013.
• Covers a wide geographic range across multiple Southern Hemisphere ocean basins.
• Data is associated with nine specific, documented research cruise identifiers.

Limitations

• Column names and exact data structure are not provided in the available metadata.
• Conflicting 'last updated' dates (2013-12-02 vs. 2026-03-06) create uncertainty about metadata maintenance.
• No information on data volume (rows, size) or licensing terms is available.
