IN2025_V06: Marine Biodiversity and Oceanographic Data from the Coral Sea Voyage

An end-of-voyage archive from the RV Investigator's IN2025_V06 expedition, titled 'The Coral Sea frontier: Deep-sea biodiversity assessment of the Coral Sea Marine Park.' The voyage was conducted by the Marine National Facility between October 10 and November 14, 2025, departing from and returning to Brisbane. Data were curated by the CSIRO National Collections and Marine Infrastructure Information and Data Centre.

Use Cases

• Modeling deep-sea biodiversity and habitat based on data from beam trawls, demersal trawls, and environmental DNA (eDNA) sampling.
• Analyzing ocean current profiles and water column properties based on Acoustic Doppler Current Profiler (ADCP) and CTD data.
• Studying air-sea gas exchange and atmospheric composition based on Greenhouse Gas Analysers, Radon sensors, and ozone sensors.
• Mapping seafloor topography and sub-bottom structure based on Multibeam Echosounder and Sub-bottom Profiler data.
• Assessing marine wildlife populations based on observations of seabirds, cetaceans, and seals.

Strengths

• Data collection spans a defined voyage period from October 10 to November 14, 2025.
• Archive includes a wide array of over 30 instrument types for regular and voyage-specific measurements.
• Data are permanently archived and made publicly available through the CSIRO Data Access Portal and MNF Data Trawler.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
