Marine Research Data from RV Investigator Voyage IN2026_V01

This archive contains raw data from the RV Investigator voyage IN2026_V01, which took place from January 02 to February 25, 2026, departing from and returning to Hobart. The data was collected using over 40 instruments, including Acoustic Doppler Current Profilers, CTD sensors, echosounders, and coring systems. The archive is curated by CSIRO's National Collections and Marine Infrastructure Information and Data Centre.

Use Cases

• Analyze current profiles and water column structure using data from the Lowered ADCP (LADCP) and CTD instruments.
• Study ocean-atmosphere gas exchange by correlating Greenhouse Gas Analyser (Picarro) and pCO2 sensor measurements.
• Map seafloor bathymetry and sub-bottom layers using data from the Multibeam Echosounder (EM712, EM124, EM2040) and Sub-bottom Profiler (SBP29).
• Investigate marine biological communities through Environmental DNA (eDNA) samples and Wildlife Observations of seabirds and cetaceans.
• Examine sediment composition and history using cores from the Multi-corer, Kasten corer, and Giant Piston Corer (GPC).

Strengths

• Data collected from a dedicated 55-day research voyage using over 40 specialized oceanographic instruments.
• Includes both regular atmospheric and oceanographic measurements alongside voyage-specific biological and geological sampling.
• Permanently archived and managed by CSIRO's National Collections and Marine Infrastructure Information and Data Centre.

Limitations

• The exact volume of data, number of rows, and specific file sizes are not provided in the input description.
• Raw data format specifics and required preprocessing steps for analysis are not detailed.
• Direct public access to raw data may require an application process via CSIRO.
