Coral Sea Marine Park Voyage Instrument and Biological Survey Archive

An archive from the RV Investigator voyage IN2025_V06, collecting oceanographic, atmospheric, and biological data in the Coral Sea Marine Park. The voyage was conducted by the CSIRO Marine National Facility between October 10 and November 14, 2025. Data includes regular instrument measurements and voyage-specific biological sampling.

Use Cases

• Map seafloor bathymetry and sub-bottom layers using Multibeam Echosounder (EM712, EM2040) and Sub-bottom Profiler (SBP29) data.
• Analyze water column properties and ocean currents from CTD, LADCP, and Thermosalinograph (TSG) time-series measurements.
• Assess deep-sea biodiversity by correlating Environmental DNA (eDNA) samples with imagery from the Deep Towed Camera (DTC) and trawl catches.
• Study air-sea interaction and greenhouse gas fluxes using Picarro analyzers for pCO2, radon sensors, and meteorological data.
• Characterize atmospheric aerosol and cloud properties with Cloud Condensation Nuclei (CCN), Condensation Particle Counters (CPC), and Cloud Radar (BASTA) observations.

Strengths

• Multidisciplinary data collection from over 30 instrument systems during a 36-day research voyage.
• Includes both continuous ocean-atmosphere measurements and targeted biological survey data (eDNA, trawls, camera).
• Curated and permanently archived by the CSIRO National Collections and Marine Infrastructure Information and Data Centre.

Limitations

• Specific row counts, file sizes, and data resolution for individual instruments are not provided in the description.
• Raw data access may be restricted initially to voyage participants, with processed data released publicly later.
• Geographic coverage is limited to the track of the RV Investigator within the Coral Sea Marine Park during the voyage period.
