Bathymetry Grids of Jervis Bay from 2007-2009 Marine Surveys

11 bathymetry grids of the Jervis Bay seabed produced from processed EM3002 data. Geoscience Australia acquired the data during marine surveys in 2007, 2008, and 2009 using the RV Kimbla, focusing on a 3x5 km grid and additional representative habitats. The dataset includes colocated sampling for sediment and infauna analysis, underwater video, photography, and tide/current measurements.

Use Cases

• Modeling seabed topography and slope based on bathymetry grids.
• Characterizing benthic habitats by correlating bathymetry with colocated sediment and infauna samples.
• Analyzing oceanographic influences by integrating bathymetry with tide and wave-generated current measurements.
• Creating base maps for marine spatial planning using the detailed 3x5 km survey grid.

Strengths

• 11 distinct bathymetry grids provide multiple data layers for analysis.
• Data collection spanned three years (2007-2009) across multiple survey missions (GA303, GA305, GA309, GA312).
• Integrated multiple data types: bathymetry, sediment samples, infauna, video, photography, and physical ocean measurements.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is explicitly not to be used for navigational purposes, restricting its application scope.
