RV Investigator Sea CO2 Measurements from Australian Voyages (2014 Onwards)

CSIRO Oceans and Atmosphere collects quality-controlled carbon dioxide (CO2) measurements from the RV Investigator research vessel. The dataset includes data from voyages starting in 2014, managed through the Integrated Marine Observing System (IMOS) Ship of Opportunity Underway Network. Data is available via the Australian Ocean Data Network (AODN) and IMOS ocean portal.

Use Cases

• Modeling oceanic carbon uptake based on underway CO2 measurements mentioned in the description
• Analyzing temporal trends in sea surface CO2 concentrations from the 2014 start date
• Validating satellite-derived ocean carbon data using in-situ measurements from the RV Investigator
• Studying the impact of specific voyages on regional carbon flux estimates

Strengths

• Quality-controlled data as stated in the description
• Data collection started in 2014, providing a multi-year time series
• Managed by the authoritative CSIRO Oceans and Atmosphere organization

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect geographic bias inherent to data_gov_au, focusing on Australian voyages
