RV Investigator Voyage IN2018_V04 EM710 MKII Multibeam Echosounder Data

September to October 2018 multibeam echosounder data collected by the RV Investigator voyage IN2018_V04. The dataset contains 11.1 GB of raw data across 23 files, capturing seafloor bathymetry, backscatter, and watercolumn backscatter in the southern extension of the East Australian Current. Data is managed by the Australian Ocean Data Network and includes processed grids in GeoTIFF format.

Use Cases

• Map seafloor topography based on processed bathymetry grids.
• Analyze seafloor composition based on backscatter information.
• Study water column acoustic properties based on watercolumn backscatter data.
• Conduct geospatial analysis of marine environments based on corrected motion and position data.

Strengths

• Data is corrected for motion and position during acquisition.
• Processed data has had outliers removed and is available in multiple formats, including GeoTIFF.
• The dataset totals 11.1 GB across 23 raw data files.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
