RV Investigator Bathymetry Data for Bass Strait Shipping Route, May-June 2018

372 files totaling 119 GB of raw bathymetry and backscatter data, plus 241 files totaling 269 GB of watercolumn backscatter data, were collected by the RV Investigator voyage IN2018_C01. The Kongsberg EM710 MKII multibeam echosounder acquired seafloor data near Wilson's Promontory and during transit from Hobart between May 28 and June 8, 2018. The Australian Ocean Data Network provides processed data in GeoTIFF and ASCII formats.

Use Cases

• Modeling seafloor bathymetry based on multibeam echosounder data
• Analyzing acoustic backscatter patterns for seabed composition
• Creating navigation safety charts for shipping routes in Bass Strait
• Studying watercolumn backscatter data for marine environmental features

Strengths

• 119 GB of raw bathymetry and backscatter data across 372 files
• 269 GB of raw watercolumn backscatter data across 241 files
• Processed data includes tide corrections and outlier removal
• Data acquisition applied sound velocity profiles and motion corrections

Limitations

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