RV Investigator Sea Carbon Dioxide Data from 2014 Onwards

Quality controlled CO2 measurements collected from 2014 onwards by the CSIRO CO2 system mounted on the RV Investigator research vessel. The data collection is part of the Integrated Marine Observing System (IMOS) Ship of Opportunity Underway Network facility and is managed by CSIRO Oceans and Atmosphere. These data are available via the Australian Ocean Data Network (AODN) and IMOS ocean portal.

Use Cases

• Modeling oceanic carbon dioxide uptake based on underway ship measurements.
• Analyzing temporal trends in sea-surface CO2 concentrations from 2014 onwards.
• Validating satellite-derived ocean carbon data against in-situ measurements.
• Studying the role of the Southern Ocean in global carbon fluxes based on data from Australian research voyages.

Strengths

• Data collection started in 2014, providing a multi-year time series.
• Data is quality controlled, as stated in the description.
• Collected via a dedicated research vessel (RV Investigator) and a specific CSIRO CO2 system.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified despite a last updated date in 2026.
