RV Investigator IN2026_T02: Marine and Atmospheric Data from Fremantle to Hobart

CSIRO's Marine National Facility collected this End of Voyage archive from the RV Investigator voyage IN2026_T02 between April 23 and May 05, 2026. The archive includes raw data from over 40 instruments measuring ocean currents, water chemistry, atmospheric gases, plankton, wildlife, and seafloor topography. Processed data from the voyage is made publicly available through the MNF Data Trawler.

Use Cases

• Modeling ocean currents and water column properties based on LADCP and CTD data.
• Analyzing greenhouse gas fluxes and atmospheric composition based on Picarro and ozone sensor data.
• Studying marine biodiversity and species distribution based on eDNA samples and wildlife observations.
• Mapping seafloor bathymetry and sub-bottom geology based on multibeam echosounder and sub-bottom profiler data.
• Investigating plankton community dynamics based on Continuous Plankton Recorder (CPR) data.

Strengths

• Data collected during a defined voyage period from April 23 to May 05, 2026.
• Archive includes raw data from over 40 distinct scientific instruments and sampling methods.
• Voyage documentation is available, and processed data is publicly accessible via the MNF Data Trawler.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The raw data archive is curated for voyage participants and processors; public access may require an application.
