Brief description
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. Digital data collected: Navigation (AIMS) Navigation (Geoscience Australia) Multibeam bathymetry and backscatter (Geoscience Australia) Single-channel sub-bottom profiler along representative lines (Geoscience Australia) CTD fluorometer, transmissometer, altimeter, PAR/Irradiance, SPAR/Surface irradiance, (AIMS) Thermo-salinograph data (AIMS) Towed video and stills with USBL positioning (AIMS) Baited Remote Underwater Video Station video from BRUVS and SISSTAS deployments (AIMS and UWA) Biological sample stills (Geoscience Australia) Physical samples collected: Water samples (Geoscience Australia) Smith-McIntyre Grab sediment samples (Geoscience Australia) Shipek Grab sediment samples (Geoscience Australia) Benthic sled biological samples (AIMS and MGNT) Plankton samples using CPR (Geoscience Australia)Notes
This research was undertaken to:1. collect physical and biological samples and data to fill major knowledge gaps for the proposed Oceanic Shoals Commonwealth Marine Reserve (CMR) in the Timor Sea
2. analyse these data to gain an understanding of patterns of community assembly and associated physical drivers of marine biodiversity including connectivity in this region
3. use national mapping and survey capacity to support further understanding of biodiversity in this region
