SSCN-SEGMENT-2-C: Shallow Waters Bathymetry in Apollo Marine Park, 2024

EGS Survey Pty Ltd collected this bathymetry data onboard the RV Bold Explorer between 24th February 2024 and 5th March 2024. The survey was conducted for the SUBCO Subsea Cable Network (SSCN) Segment 2-C route within the Apollo Marine Park. It was commissioned to identify a viable cable route by assessing seabed features, slopes, and obstacles.

Use Cases

• Identify seabed slopes exceeding 6 degrees for cable route planning based on the survey's primary purpose.
• Map obstacles like rock outcrops and existing infrastructure for cable burial feasibility assessment.
• Analyze shallow geology and seabed features for engineering and construction planning of the SSCN cable.
• Support environmental and regulatory assessments for cable laying within the Apollo Marine Park boundary.

Strengths

• Data was acquired during a dedicated hydrographic survey between specific dates in 2024.
• Survey purpose is clearly defined for engineering a subsea cable route, suggesting focused data collection.
• The dataset is confined to a specific geographic area: the Apollo Marine Park.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and data scale are unknown, which may limit suitability assessment.
• The description explicitly states the data is not to be used for navigational purposes, limiting its application.
