RV Investigator Sea Carbon Dioxide Measurements from 2014 Onwards

From 2014 onwards, this dataset contains quality-controlled underway measurements of sea carbon dioxide (CO2) collected 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 and is managed by CSIRO Oceans and Atmosphere. 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.
• Analyzing temporal trends in sea surface CO2 concentrations from 2014 onwards.
• Validating satellite-derived ocean carbon data against in-situ shipboard measurements.
• Assessing regional variability in ocean acidification based on quality-controlled CO2 data.

Strengths

• Data is quality controlled, as stated in the description.
• Collected from 2014 onwards, providing a multi-year time series.
• Gathered using 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 voyages of the RV Investigator.
