Tangaroa Underway Carbon Dioxide and Oceanographic Measurements, 2015

Fourteen research cruises aboard the R/V Tangaroa collected surface underway data from January 5 to December 23, 2015. The dataset includes measurements of the partial pressure of carbon dioxide in air and water, sea surface temperature, salinity, and barometric pressure from the South Pacific Ocean, Southern Ocean, and Tasman Sea. Data were collected using a carbon dioxide gas analyzer and a shower head chamber equilibrator.

Use Cases

• Calculating air-sea CO2 flux based on partial pressure differences.
• Analyzing seasonal variability of surface ocean pCO2 in the Southern Ocean.
• Validating ocean carbon cycle models with in-situ underway measurements.
• Correlating sea surface temperature and salinity with carbon dioxide concentrations.

Strengths

• Covers a full annual cycle of measurements from 2015-01-05 to 2015-12-23.
• Includes data from fourteen distinct research cruises, suggesting repeated transects.
• Specific instruments are named: Carbon dioxide (CO2) gas analyzer and Shower head chamber equilibrator.

Limitations

• Column names and exact data structure are not provided by any source.
• Exact row count and file size are unknown.
• License information is not specified on any platform.
