Description
NESP D3 Project gridded multi-beam echo-sounder bathymetry data for Hunter Marine Park, acquired by NSW DPIE aboard RV Bombora. Surveys were conducted in 2015 and 2018-2019, funded by NSW DPIE and the National Environmental Science Program. The data supports reports by Davies et al (2016) and Williams et al (2020) on mapping shelf rocky reef habitats and characterising seabed habitats, fish, and sessile invertebrate assemblages.
Use Cases
Map seabed topography and depth based on multi-beam echo-sounder surveys.
Identify and analyze Key Ecological Features like 'Continental Shelf Reef' based on focused mapping areas.
Characterize seabed habitats for fish and sessile invertebrate assemblages based on integrated survey data.
Support marine park management and monitoring based on detailed bathymetric coverage.
Strengths
Data is sourced from focused mapping surveys in 2018-19 providing 100% coverage over identified reef areas.
Fieldwork was funded and conducted across multiple years (2015 and 2018) by NSW DPIE and NESP.
Data is linked to specific published scientific reports detailing methodology and findings.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
Row count is unknown, which may limit suitability assessment.
Data is explicitly not to be used for navigational purposes.
