SSCN Segment 2-C: Nelson Marine Park Bathymetry and Seabed Survey (2024)

Nelson Marine Park bathymetry and seabed data were collected by EGS onboard the RV Bold Explorer in April 2024. The survey investigated seabed features and shallow geology along a proposed subsea cable route and included a subsequent geotechnical sampling program. The dataset is part of the SUBCO Subsea Cable Network (SSCN) cable route survey and is not for navigational use.

Use Cases

• Modeling seabed terrain for subsea infrastructure planning based on bathymetry data.
• Analyzing seabed composition and features for marine habitat studies based on the shallow geology investigation.
• Calibrating marine survey equipment and methods based on the described DGPS and MBES calibration procedures.

Strengths

• Data collection followed a documented calibration protocol for positioning and multibeam echosounder systems.
• Survey scope includes both bathymetry and subsequent geotechnical sampling, suggesting complementary data layers.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and spatial resolution are unknown, which may limit suitability assessment.
