Stereo-Baited Remote Underwater Video Stations (BRUVS) were deployed and retrieved in targeted shallow seabed environments within the proposed Oceanic Shoals Commonwealth Marine Reserve (CMR) in the Timor Sea. The survey concentrated on shelf habitats (< 200m) of the western part of the Oceanic Shoals CMR and included potential biodiversity hotspots such as pinnacles, banks and shoals. In total, 56 stereo-BRUVS were deployed between 31 and 77 metres for one hour according to a regular random sampling design, with minimum spacing of 400 m to ensure independence among samples.
The dataset depicts the proclamations made under the Seas and Submerged Lands Act (SSLA) 1973. This includes the continental shelf, the Exclusive Economic Zone (EEZ), territorial sea and territorial sea baselines.
Stereo Baited Remote Underwater Video Stations (BRUVS) were deployed and retrieved across two shoals of regional interest, Evans and Tassie Shoals, two of the closest shoals to the Barossa field. The allocation of deployment positions across each shoal was conducted using a regular/random design within the bounds of the 60 m depth contour whilst maintaining a minimum distance of 250 m between each stereo-BRUVS unit. Once the positions were derived, the sequence of deployments, in sets of eight replicate units, was determined by proximity and prevailing sea conditions on the day.
Towed video surveys were carried out in targeted shallow seabed environments within the proposed Oceanic Shoals Commonwealth Marine Reserve (CMR) in the Timor Sea. The survey concentrated on shelf habitats (< 200m) of the western part of the Oceanic Shoals CMR and included potential biodiversity hotspots such as pinnacles, banks and shoals. In total, 52 towed video transects were collected at depths of between 31 and 129 metres.
