RV Investigator Antarctic Seafloor Bathymetry and Backscatter Data, Jan-Feb 2026

January 02, 2026 to February 25, 2026 (AEST) multibeam echosounder data from the RV Investigator voyage IN2026_V01 around Antarctica. The Kongsberg EM712 system collected 15.7 GB of raw bathymetry and backscatter data and 30.1 GB of watercolumn backscatter data, stored by CSIRO. Data are corrected for motion, position, and tide using the EGM2008 model.

Use Cases

• Map seafloor topography based on processed bathymetry data.
• Analyze seafloor composition based on backscatter intensity information.
• Study water column features based on watercolumn backscatter data.
• Conduct geospatial analysis of Antarctic marine ecosystems based on the defined survey area.

Strengths

• 158 files totaling 15.7 GB of raw bathymetry/backscatter data and 30.1 GB of watercolumn data.
• Data are corrected for motion, position, and GPS tide using the EGM2008 model.
• Sound velocity profiles were applied during acquisition and outliers have been removed from processed data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
