IN2025_V06: RV Investigator Coral Sea Marine Park Voyage Data Archive

One voyage, IN2025_V06, conducted by the Marine National Facility RV Investigator between October 10 and November 14, 2025, focused on the Coral Sea Marine Park. The archive contains raw data from over 40 instruments, including multibeam echosounders, CTDs, environmental DNA samplers, and atmospheric sensors. Data is curated by CSIRO's National Collections and Marine Infrastructure Information and Data Centre and archived at the CSIRO Data Access Portal.

Use Cases

• Map seafloor bathymetry and sub-bottom features based on multibeam echosounder and sub-bottom profiler data.
• Assess deep-sea biodiversity and species distribution based on beam trawl, demersal trawl, and environmental DNA (eDNA) samples.
• Analyze ocean current profiles and water column properties based on Acoustic Doppler Current Profiler (ADCP) and CTD data.
• Study air-sea interactions and atmospheric composition based on greenhouse gas analyzers, radon sensors, and meteorological instruments.
• Conduct wildlife population surveys based on observations of seabirds, cetaceans, and seals.

Strengths

• Data collected during a dedicated 36-day research voyage with a clear scientific objective.
• Archive integrates measurements from over 40 distinct instruments, covering oceanographic, atmospheric, and biological parameters.
• Permanently archived by a recognized national research organization (CSIRO) with a public access pathway 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 for large-scale ML tasks.
• Description metadata is limited; actual data quality and completeness require manual inspection after download.
