SSCN Segment 2-B: Marine Park Bathymetry and Seabed Survey, April 2024

A bathymetry dataset from a survey conducted onboard the RV Bold Explorer from 17th to 20th April 2024. The survey investigated bathymetry, seabed features, and shallow geology along a proposed subsea cable route within the South-west Corner Marine Park near Fremantle, Australia. The dataset is provided by Geoscience Australia Data and is not for navigational purposes.

Use Cases

• Modeling seabed topography based on multibeam echosounder (MBES) data mentioned in the description
• Identifying potential seabed hazards for infrastructure projects based on the survey of seabed features and shallow geology
• Analyzing bathymetric variation within a marine protected area based on the confined survey area
• Calibrating or validating other marine geospatial datasets based on the described calibration procedures for positioning and sensor systems

Strengths

• Describes a specific, time-bound survey conducted from 17th to 20th April 2024
• Details a multi-faceted survey covering bathymetry, seabed features, and shallow geology
• Documents specific calibration procedures for DGPS, gyros, and multibeam echosounders

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count and file size are unknown, which may limit suitability assessment
• Data may reflect geographic and temporal bias inherent to the single survey location and period
