This project updates the 2019 predictive benthic habitat map, extending past the subtidal zone of the harbour to include intertidal habitats. The project worked with collaborators to synthesise existing data sets for inclusion in benthic habitat mapping process. Hydrodynamic model variables were updated and new digital elevation data included to provide a more accurate representation of the bed shear stress, waves and current. LiDAR surveys were conducted to fill in the gap between the IX bathymetric survey and the high tide water mark. The LiDAR survey data extended the existing bathymetry data. A total of 30 Towed video transects were conducted in areas predicted to have a high probability of benthic fauna occurrence based on the existing predictive model.
The benthic habitat model was updated to include NTG historical data, new towed video data, hydrodynamic and light data.
