Bass Strait Seafloor Bathymetry and Backscatter from RV Investigator Voyage IN2018_C01

May 28 to June 8, 2018, the RV Investigator collected multibeam echosounder data in Bass Strait and near Wilson's Promontory. The dataset includes 372 files (119 GB) of raw bathymetry and backscatter data and 241 files (269 GB) of raw watercolumn backscatter data, processed with motion, position, and tide corrections. Data is managed by the Australian Ocean Data Network and stored at CSIRO.

Use Cases

• Modeling seafloor topography for safe shipping route planning based on bathymetry data.
• Analyzing seafloor composition and texture based on backscatter information.
• Studying water column acoustic properties based on watercolumn backscatter data.
• Creating high-resolution nautical charts based on processed bathymetry grids.

Strengths

• Data is corrected for motion, position, and tides, indicating a processed quality level.
• The dataset contains 610 GB of raw data across two formats, suggesting significant spatial coverage.
• The echosounder's nominal frequency range of 40 to 100 kHz provides high-resolution detail.

Limitations

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