RV Investigator IN2014_E04: Seafloor Bathymetry East of Hobart

RV Investigator voyage IN2014_E04 collected 4.89 GB of multibeam echosounder data east of Hobart between 26 and 28 November 2014. The Kongsberg EM710 system acquired raw seafloor bathymetry and backscatter information, stored in *.all format by CSIRO Oceans and Atmosphere. Processed data are available in XYZ and GSF formats.

Use Cases

• Model seafloor topography based on bathymetry data mentioned in the description
• Analyze seabed composition based on backscatter information
• Calibrate acoustic survey methodologies based on documented sound velocity profiles
• Conduct regional marine habitat mapping based on geospatial seafloor data

Strengths

• 4.89 GB of raw data across 50 files provides substantial coverage for the survey area
• Data acquisition applied sound velocity profiles for accuracy
• Processed data available in multiple standard formats (XYZ, GSF)

Limitations

• Tide corrections were not applied to the processed data, which may affect vertical accuracy
• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
