Description
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'.
