NESP D3 Hunter Marine Park Bathymetry 2019

Gridded multi-beam echosounder bathymetry data for the Hunter Marine Park, acquired during surveys in 2015 and 2018. The data was funded by NSW DPIE and the National Environmental Science Program to map seabed habitats and support biodiversity monitoring. Survey sites included areas east of Seal Rocks and the Broughton Islands, focusing on the Key Ecological Feature 'Continental Shelf Reef'.

Use Cases

• Modeling seabed topography based on multi-beam echosounder bathymetry data.
• Analyzing the distribution of the 'Continental Shelf Reef' Key Ecological Feature based on mapped survey areas.
• Characterizing fish and sessile invertebrate assemblages in relation to mapped bathymetry and habitat data.
• Monitoring changes in marine biodiversity assets on the continental shelf over time.

Strengths

• Data includes 100% coverage surveys over previously identified key ecological areas from 2018.
• Surveys were conducted across multiple years (2015 and 2018) for exploratory and focused mapping.

Limitations

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