RV Investigator Sea Carbon Dioxide Measurements from 2014 Onwards

From 2014 onwards, quality-controlled carbon dioxide (CO2) measurements collected from the RV Investigator research vessel. The data is part of the Integrated Marine Observing System (IMOS) Ship of Opportunity Underway Network facility and managed by CSIRO Oceans and Atmosphere. It 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 trends in sea surface CO2 concentrations over time.
• Validating satellite-derived ocean carbon data with in-situ shipboard measurements.
• Assessing the impact of ocean acidification on marine ecosystems based on CO2 levels.

Strengths

• Data is quality controlled, as stated in the description.
• Time series begins in 2014, providing a multi-year record.
• Data collection is part of the established IMOS and CSIRO research infrastructure.

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 the last updated date of 2026-05-12.
