RV Investigator IN2018_V04 Multibeam Sonar Bathymetry and Backscatter

11.1 GB of raw multibeam echosounder data from RV Investigator voyage IN2018_V04, collected between 11 September and 8 October 2018. Kongsberg EM710 MKII equipment acquired seafloor bathymetry, backscatter, and watercolumn backscatter data with a nominal frequency range of 40 to 100 kHz. Processed data grids are available in GeoTIFF format.

Use Cases

• Map seafloor bathymetry based on processed GeoTIFF grids mentioned in the description.
• Analyze sediment properties based on seafloor backscatter information.
• Study watercolumn acoustic features based on watercolumn backscatter data.
• Model oceanographic currents based on bathymetry corrected for motion and position.

Strengths

• 23 raw data files totaling 11.1 GB provide substantial raw data volume.
• Data includes bathymetry, seafloor backscatter, and watercolumn backscatter from a specific scientific voyage.
• Processed data is available in multiple formats including GeoTIFF grids and ASCII.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Tide corrections status is ambiguous, noted as '[were/were not] applied'.
