May 28 to June 8, 2018 survey data collected by the RV Investigator during voyage IN2018_C01, focusing on shipping routes in Bass Strait. The Kongsberg EM710 MKII multibeam echosounder acquired seafloor bathymetry, backscatter, and watercolumn data near Wilson's Promontory and during transit. The dataset includes 372 files (119 GB) of raw bathymetry/backscatter and 241 files (269 GB) of raw watercolumn data, with processed grids available in GeoTIFF format.
Use Cases
- Update nautical charts for safe shipping navigation based on modern bathymetric survey data.
- Analyze seafloor composition and texture based on acoustic backscatter information.
- Model underwater topography and habitat based on high-resolution bathymetry grids.
- Study watercolumn acoustic properties based on the available watercolumn backscatter data.
Strengths
- Data includes 119 GB of raw bathymetry and backscatter files and 269 GB of raw watercolumn files.
- Processed data has been corrected for motion, position, tide, and outliers.
- Data acquisition utilized a Kongsberg EM710 MKII multibeam echosounder with a nominal frequency range of 40-100 kHz.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
