Hunter Marine Park Bathymetry Grids from MBES Surveys 2015-2018

Hunter Marine Park in Australia contains gridded multi-beam echo-sounder bathymetry data. Surveys were funded by NSW DPIE and the National Environmental Science Program in 2015 and 2018, focusing on the continental shelf reef Key Ecological Feature. Reports by Davies et al (2016) and Williams et al (2020) detail the surveys and associated habitat characterization work.

Use Cases

• Model seabed topography based on gridded bathymetry data
• Analyze habitat distribution for the Key Ecological Feature 'Continental Shelf Reef'
• Integrate bathymetry with towed video and BRUV data for ecological characterisation
• Map specific survey sites east of Seal Rocks and Broughton Island

Strengths

• Data is gridded, suggesting structured spatial coverage
• Surveys targeted 100% coverage over previously identified reef areas in 2018
• Fieldwork was funded by two government programs (NSW DPIE and NESP)

Limitations

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