RV Investigator Voyage IN2018_C01: Multibeam Echosounder Bathymetry and Backscatter Data

Bass Strait and waters near Wilson's Promontory were surveyed by the RV Investigator voyage IN2018_C01 from May 28 to June 8, 2018. The Kongsberg EM710 MKII multibeam echosounder collected seafloor bathymetry, backscatter, and watercolumn backscatter data, totaling 119 GB of raw bathymetry data and 269 GB of raw watercolumn data. The data, stored by CSIRO, includes processed grids and line data with motion, position, and tide corrections applied.

Use Cases

• Creating high-resolution nautical charts based on modern bathymetric survey data.
• Analyzing seafloor composition and texture using backscatter information.
• Modeling underwater acoustic propagation based on watercolumn backscatter data.
• Assessing shipping route safety in Bass Strait based on updated bathymetry.

Strengths

• 372 files of raw bathymetry and backscatter data totaling 119 GB.
• 241 files of raw watercolumn backscatter data totaling 269 GB.
• Data has been processed with motion, position, and tide corrections applied.
• Processed data is available in multiple formats including GeoTIFF and ASCII.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified; last metadata update was 2026-06-27.
