NCEI 0157248: Ocean Carbon and Sea Surface Measurements from RV Tangaroa

NCEI Accession 0157248 contains surface underway chemical, meteorological, and physical data collected by the RV Tangaroa research vessel across the Arafura Sea, Coral Sea, South Pacific Ocean, Tasman Sea, and Timor Sea. The dataset includes measurements of the partial pressure of carbon dioxide in air and water, barometric pressure, salinity, and sea surface temperature, collected using a Carbon dioxide (CO2) gas analyzer. Data were gathered during nine distinct research cruises led by Dr. Kim I Currie of the National Institute of Water and Atmospheric Research Limited between February and December 2014.

Use Cases

• Calculating air-sea carbon dioxide flux based on partial pressure measurements.
• Analyzing spatial and temporal patterns of ocean acidification in the South Pacific.
• Correlating sea surface temperature and salinity with carbon dioxide concentrations.
• Validating regional carbon cycle models with in-situ underway data.

Strengths

• Data covers a wide geographic area across five distinct seas and oceans.
• Measurements are temporally specific, collected during nine discrete research cruises over a 10-month period.
• Data collection is attributed to a specific principal investigator and research institution.

Limitations

• Key metadata such as row count, file size, and specific column names are unavailable across all sources.
• Sources conflict on the 'last updated' date, with one listing 2014-12-23 and others listing 2026-03-06.
• The license for data use is not specified.
