Survey FK200308 on the R/V Falkor undertook detailed mapping within two significant and biologically unexplored submarine canyons (Cape Range and Cloates Canyon) in the Gascoyne Marine Park. The Gascoyne Marine Park covers 81, 766 km2 adjacent to the Ningaloo Marine Park. The canyons form part of the habitat protection and multiple use zones of the marine park and are identified as Key Ecological Features. The canyons provide an important connection between the abyssal plain environments and the Commonwealth waters adjacent to Ningaloo Reef on the continental shelf. High productivity aided by upwelling through the canyons has been related to aggregations of whale sharks, manta rays, humpback whales, sea snakes, sharks, large predatory fish and seabirds. In addition, the hard canyon walls provide habitat for a range of sessile invertebrates, while the soft sediments on the canyon floor support a range of mobile invertebrates. The data from this survey will provide a comprehensive taxonomic survey to characterise the marine biodiversity of the canyons or to understand the distribution of canyon habitats in relation to the seabed morphology. Bathymetry and acoustic reflectance (backscatter) data were acquired in the survey region using a Kongsberg 30 kHz EM 302 deep water multi-beam echo sounder with a 1° array. An area of 11,250 km2 was surveyed along 4100 line kilometres within the Gascoyne Marine Park. In addition, 2495 line kilometres was surveyed along transits between Fremantle, Exmouth and Broome. Navigation and motion were recorded with an Applanix POSMV V5, while sound speed profiles were processed with the software Sound Speed Manager to correct acoustic data.

Survey INV2019T02 was conducted under the National Marine Facility’s supplementary voyage opportunities on the RV Investigator between the 4th to 14th October 2019, with multiple discrete projects and principal investigators. One of these projects aimed to characterise habitats of targeted areas within Wessel Marine Park, providing crucial baseline information to better understand and manage this marine park, including those sites sacred to local indigenous communities. As part of this project, four 1500 m video transects were undertaken across a range of geomorphic features and depth gradients focussed on a deep hole feature within and adjacent to the Wessel Marine Park. Raw video files are located in folder 'INV2019T02_TOWVID_VIDEOS', named by station number and camera tow. These do not have georeferencing. The benthic environment in the study area was highly turbid with strong currents, and associated imagery can therefore only be used for habitat classification, coarse morphospecies identification, or defining broad biological communities. Onboard habitat annotations are included as an excel file, with camera positioning included.

This resource includes bathymetry data acquired during the Submarine Cape Range Canyons bathymetry survey using Kongsberg EM302 and EM710 multibeam sonar systems. The Seamounts, Canyons and Reefs of the Coral Sea bathymetry survey was led by Dr. Rachel Przeslawski (Geoscience Australia) with a team of scientists from Geoscience Australia, Curtin University, Western Australian Museum and Scripps Institution of Oceanography aboard the Schmidt Ocean Institute (SOI) RV Falkor from the 8th of March to the 8th of April 2020. The primary objective of this survey was to map unexplored submarine canyons in the Gascoyne Marine Park. Submarine canyons are crucial habitats for a variety of biota and understanding their geometry, depth and species diversity is underpinned by high resolution bathymetry data. The bathymetry data collected in this survey can assist with scientific research, marine park management and understanding Australia’s marine estate. This dataset contains a 64m and a 16m, for water depths shallower than 2560m resolution 32-bit geotiff of the Cape Range and Cloates Canyons area produced from the processed EM302 and EM710 bathymetry data combined. This dataset is not to be used for navigational purposes. This dataset is published with the permission of the CEO, Geoscience Australia.

The Vlaming Basin survey (GA survey # 334) was conducted under the Nation CO2 Infrastructure Plan (NCIP) on the MV Southern Supporter between the 12th to the 21st April 2012, with technical support provided from Fugro. The survey obtained geological (sedimentological, geochemical, geophysical) and biological data to support assessments of offshore acerage release areas for potential CO2 storage, and investigate the relationships between the physical environment and associated biota for biodiversity prediction. The purpose of the survey was to contribute to the assessment of the Vlaming Sub-basin for containment risk, as well as complement and validate interpretation of seismic data in the same area. Underwater footage was collected from 12 stations, although quality varies between sites and among transect lines. Video folders are named according to station number, followed by gear code (CAM=Ray Tech Underwater system), then the deployment number, and followed by region. For example, 12CAM02_D1 represents a video transect from station 12 that was the 2nd video transect of the survey and located in area region D1. Multiple files within transect folders indicate location metadata (Start of line location). In addition, USBL (Ultra-short baseline) text files located in the same folder provide continuous navigational information on location, time (UTC) and depth of each video transect line.

Geoscience Australia undertook a marine survey of the Leveque Shelf (survey number SOL5754/GA0340), a sub-basin of the Browse Basin, in May 2013. This survey provides seabed and shallow geological information to support an assessment of the CO2 storage potential of the Browse sedimentary basin. The basin, located on the Northwest Shelf, Western Australia, was previously identified by the Carbon Storage Taskforce (2009) as potentially suitable for CO2 storage. The survey was undertaken under the Australian Government's National CO2 Infrastructure Plan (NCIP) to help identify sites suitable for the long term storage of CO2 within reasonable distances of major sources of CO2 emissions. The principal aim of the Leveque Shelf marine survey was to look for evidence of any past or current gas or fluid seepage at the seabed, and to determine whether these features are related to structures (e.g. faults) in the Leveque Shelf area that may extend to the seabed. The survey also mapped seabed habitats and biota to provide information on communities and biophysical features that may be associated with seepage. This research, combined with deeper geological studies undertaken concurrently, addresses key questions on the potential for containment of CO2 in the basin's proposed CO2 storage unit, i.e. the basal sedimentary section (Late Jurassic and Early Cretaceous), and the regional integrity of the Heywood Formation (the seal unit overlying the main reservoir). Underwater footage was collected from 49 stations, although quality varies between sites. Video files are located in folder 'SOL5754_TOWVID_VIDEOS'. Each avi file contains several video transects; the associated stations are noted in the file name. Real-time onboard video characterisations using the AIMS- TowedVid classification system are located in folder 'SOL5754_TOWVID_CSVs'. Still images are located in folder 'SOL5754_TOWVID_STILLS' with sub-folders named according to station number, followed by gear code (CAM=underwater camera system), then the deployment number. For example, 12CAM02 represents a video transect from station 12 that was the 2nd video transect of the survey. USBL (Ultra-short baseline) text files are located in folder 'SOL5754_USBL_FILES' and provide continuous navigational information on location, time (UTC) and depth of each video transect line.
