IN2018_C01: Multibeam Echosounder Bathymetry and Backscatter Data for Bass Strait

Multibeam echosounder data from the RV Investigator voyage IN2018_C01, collected from May 28 to June 8, 2018. The dataset includes 372 files (119 GB) of raw bathymetry and backscatter data and 241 files (269 GB) of raw watercolumn data, focused on the shipping route through Bass Strait near Wilson's Promontory. Data were collected by the Australian Ocean Data Network using a Kongsberg EM710 MKII system and are stored in raw and processed formats.

Use Cases

• Generate high-resolution seafloor maps based on the bathymetry and backscatter information.
• Analyze water column acoustic properties for marine research based on the watercolumn backscatter data.
• Model shipping route safety and navigation hazards based on the surveyed primary shipping route through Bass Strait.
• Calibrate or validate acoustic sensor models using the detailed frequency (40-100 kHz) and angular resolution specifications.

Strengths

• Includes 119 GB of raw bathymetry & backscatter data and 269 GB of raw watercolumn data, indicating substantial volume.
• Data has been processed with motion, position, tide, and sound velocity corrections, and outliers have been removed.
• Provides multiple processed formats (.gsf, ascii, geotiff) for different analysis needs.

Limitations

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