Nelson Marine Park Bathymetry Survey Data from April 2024

Bathymetry data from the SSCN Segment 2-C survey within Nelson Marine Park, acquired by EGS onboard the RV Bold Explorer in April 2024. The dataset contains seabed depth and feature information collected using multibeam echosounder systems. It is published by Geoscience Australia.

Use Cases

• Analyze seabed features and shallow geology along the proposed cable route using bathymetry data.
• Process multibeam echosounder (MBES) data for marine habitat mapping within Nelson Marine Park.
• Integrate bathymetry data with geotechnical sampling results for seabed engineering assessments.

Strengths

• Data collected using calibrated DGPS positioning and survey gyros onboard a dedicated survey vessel.
• Survey includes both shallow water and deep water multibeam echosounder (MBES) calibration.
• Dataset is part of a broader survey investigating bathymetry, seabed features, and shallow geology.

Limitations

• Dataset is not to be used for navigational purposes, limiting its application.
• Specific data format, resolution, and coverage extent within the park are not detailed.
• No sample data or column structure is provided, complicating initial assessment.
