RV Investigator Voyage IN2014_E04: Seafloor Bathymetry East of Hobart

RV Investigator voyage IN2014_E04 collected multibeam echosounder data east of Hobart between 26 and 28 November 2014. The Kongsberg EM710 instrument acquired seafloor bathymetry and backscatter information, stored as 50 files totaling 4.89 GB of raw data. Processed data in XYZ and GSF formats are available from CSIRO Oceans and Atmosphere.

Use Cases

• Create high-resolution seafloor bathymetric maps based on multibeam echosounder data.
• Analyze seafloor backscatter intensity for substrate classification.
• Model underwater terrain for habitat mapping or geological studies.
• Validate or calibrate other marine geospatial datasets using the processed XYZ and GSF data.

Strengths

• Data volume is precisely quantified at 4.89 GB across 50 files.
• Sound velocity profiles were applied during acquisition, likely improving data accuracy.
• Processed data are available in multiple standard formats (XYZ and GSF).

Limitations

• Tide corrections were not applied to the processed data, which may affect vertical accuracy.
• Description metadata is limited; actual data quality requires manual inspection after download.
• Row count is unknown, which may limit suitability assessment.
