RV Investigator Voyage IN2026_V01: Antarctic Marine and Atmospheric Data

The RV Investigator voyage IN2026_V01 collected data from January 02, 2026 to February 25, 2026, departing from and returning to Hobart. The archive contains raw data from over 40 instruments, including acoustic profilers, greenhouse gas analyzers, echosounders, corers, and atmospheric sensors, curated by the CSIRO National Collections and Marine Infrastructure. Processed data from the 'Cook Ice Ecosystems and Sediments' voyage is made publicly available through the MNF Data Trawler.

Use Cases

• Modeling ocean currents and water column structure based on Acoustic Doppler Current Profiler (ADCP) and CTD data
• Analyzing marine sediment composition and history based on core samples from the Multi-corer, Kasten corer, and Giant Piston Corer
• Studying atmospheric aerosols and cloud formation based on Cloud Condensation Nuclei (CCN) and Mobility Particle Size Spectrometer (MPSS) measurements
• Investigating marine biodiversity and species distribution based on Environmental DNA (eDNA) samples and wildlife observations
• Mapping seafloor topography and sub-bottom layers based on Multibeam Echosounder and Sub-bottom Profiler data

Strengths

• Data collected over a 55-day voyage in the Antarctic region during January and February 2026
• Includes measurements from over 40 specialized instruments covering oceanographic, atmospheric, and geophysical domains
• Archive is curated and permanently hosted by the CSIRO Data Access Portal, indicating institutional stewardship

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• The description provides instrument lists but not specifics on data volume, resolution, or processing level
