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

Quality-controlled carbon dioxide measurements collected from 2014 onwards by the CSIRO CO2 system mounted on the Research Vessel RV Investigator. The data collection is part of the Integrated Marine Observing System (IMOS) Ship of Opportunity Underway Network facility, managed by CSIRO Oceans and Atmosphere. Data are 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 2014 onwards
• Validating satellite-derived ocean carbon data using in-situ measurements from a research vessel
• Studying the relationship between oceanographic conditions and CO2 levels in Australian marine regions

Strengths

• Data collection began in 2014, providing a multi-year time series.
• Data is described as quality-controlled.
• Data is collected via a dedicated CSIRO CO2 system on a national research vessel.

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 RV Investigator voyage routes.
