Darwin Harbour Middle Arm Benthic Habitat Mapping

This project updates the 2019 predictive benthic habitat map for this region, 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.

Resource lineage

Statement
Trip ID 7503 The layers are a product of the benthic habitat mapping activities and a direct outcome of the previous collaborative work between the Department of Environment and Natural Resources, Northern Territory Government (DENR), Geoscience Australia (GA) and the Australian Institute of Marine Science (AIMS). The Lidar survey was conducted using one of Airborne Research Australia's purpose-built research motorgliders, a Diamond Aircraft HK36TTC-ECO Dimona. ARA flew a collection of parallel flight paths in the Darwin Harbour intertidal area and Middle Arm between the 16th-19th November. Full data processing descriptions are found in the report, (2021) Revised predictive benthic habitat map for Darwin Harbour. Report prepared for Department of Environment, Parks and Water Security.
