Innovative Visualisation for Australia's Marine Zone

Geoscience Australia collects and manages large amounts of data for Australia's marine zone, including bathymetry data and the legal boundaries of petroleum acreage release areas. Communicating this information to non-specialists can be difficult. To overcome this communication problem Geoscience Australia uses innovative visualisation techniques, including 3D flythroughs and video editing, to integrate raster and vector geospatial data into enhanced multimedia products. Geoscience Australia has used these techniques for a number of years and the resulting products are highly regarded by stakeholders interested in marine zone management and petroleum exploration. This paper examines four case studies where these innovative techniques were used to effectively communicate marine zone information with a wide audience.

Ord Basin hydrogeological inventory

This Ord Basin dataset contains descriptive attribute information for the areas bounded by the relevant spatial groundwater feature in the associated Hydrogeology Index map. Descriptive topics are grouped into the following themes: Location and administration; Demographics; Physical geography; Surface water; Geology; Hydrogeology; Groundwater; Groundwater management and use; Environment; Land use and industry types; and Scientific stimulus.

The Ord Basin, an intracratonic sedimentary basin, covers about 8000 square kilometres on the border of Western Australia and the Northern Territory. It was once part of the extensive Centralian Superbasin, which deposited sediments across central and northern Australia from the Proterozoic to early Palaeozoic era. The Ord Basin comprises three synclines with up to 2500 m of Cambrian and Devonian sedimentary rocks, separated by major faults and Proterozoic basement highs.

The basin's northern boundary is defined by the Halls Rewards Fault and Proterozoic basement rocks, separating it from the Bonaparte Basin. The western edge overlies rocks of the Paleoproterozoic Halls Creek Orogen, while the eastern margin is separated from the Wiso Basin by volcanic Kalkarindji Province and Proterozoic Birrindudu and Victoria basins. The southern boundary is formed by the Negri Fault and Proterozoic basement highs.

The depositional history of the Ord Basin can be divided into three phases. The early Cambrian witnessed extensive basaltic volcanism, forming the Antrim Plateau Volcanics. Subsequently, the Cambrian marine transgression deposited carbonates and clastic rocks of the Goose Hole Group, including the Elder and Negri Subgroups. The Late Devonian saw the deposition of continental sandstones and conglomerates of the Mahony Group.

Throughout the basin's evolution, tectonic movements and erosional processes shaped its present configuration. The Alice Springs Orogeny (450 to 300 Ma) caused deformation and landscape changes, resulting in the deposition of the Mahony Group. Periodic reactivation of growth faults in the underlying Birrindudu Basin and subsequent erosion contributed to the basin's current structure.

The Ord Basin's three synclines are the Hardman Syncline (southern and largest), the Rosewood Syncline (central), and the Argyle Syncline (northern). The Hardman Syncline holds the full succession of basin strata.

Digital Earth Australia Intertidal

Intertidal environments contain many important ecological habitats such as sandy beaches, tidal flats, rocky shores, and reefs. These environments also provide many valuable benefits such as storm surge protection, carbon storage, and natural resources.&nbsp;

&nbsp;

Intertidal zones are being increasingly faced with threats including coastal erosion, land reclamation (e.g. port construction), and sea level rise. These regions are often highly dynamic, and accurate, up-to-date elevation data describing the changing topography and extent of these environments is needed. However, this data is expensive and challenging to map across the entire intertidal zone of a continent the size of Australia. &nbsp;

&nbsp;

The intertidal zone also forms a critical habitat and foraging ground for migratory shore birds and other species. An improved characterisation of the exposure patterns of these dynamic environments is important to support conservation efforts and to gain a better understanding of migratory species pathways. &nbsp;

&nbsp;

The DEA Intertidal product suite (https://knowledge.dea.ga.gov.au/data/product/dea-intertidal) provides annual continental -scale elevation and exposure products for Australia’s intertidal zone, mapped at a 10m resolution, from Digital Earth Australia’s archive of open-source Landsat and Sentinel-2 satellite data. These intertidal products enable users to better monitor and understand some of the most dynamic regions of Australia’s coastlines.



Applications



   - Integration with existing topographic and bathymetric data to seamlessly map the elevation of the coastal zone.&nbsp;

&nbsp;

    - Providing baseline elevation data for predicting the impact of coastal hazards such as storm surges, tsunami inundation, or future sea-level rise.&nbsp;

&nbsp;

    - Investigating coastal erosion and sediment transport processes.&nbsp;

&nbsp;

   - Supporting habitat mapping and modelling for coastal ecosystems extending across the terrestrial to marine boundary.&nbsp;

&nbsp;

    - Characterisation of the spatio-temporal exposure patterns of the intertidal zone to support migratory species studies and applications.&nbsp;

Lord Howe Island feeding guild spreadsheet

Geoscience Australia carried out a marine survey on Lord Howe Island shelf (NSW) in 2008 (SS06_2008) to map seabed bathymetry and characterise benthic environments through colocated sampling of surface sediments and infauna, rock coring, observation of benthic habitats using underwater towed video, and measurement of ocean tides and wave generated currents. Subbottom profile data was also collected to map sediment thickness and shelf stratigraphy. Data and samples were acquired using the National Facility Research Vessel Southern Surveyor. Bathymetric data from this survey was merged with other preexisting bathymetric data (including LADS) to generate a grid covering 1034 sq km. As part of a separate Geoscience Australia survey in 2007 (TAN0713), an oceanographic mooring was deployed on the northern edge of Lord Howe Island shelf. The mooring was recovered during the 2008 survey following a 6 month deployment.

Feeding guild counts per sample.  Aggregated from species level data in LHI_Infauna_species (27Oct10).csv using the information in LHI_taxa_info.xls

A Crustal Transect between Precambrian Australia and the Timor Trough across the Vulcan Sub-basin

Wide-angle seismic data from ocean bottom seismographs, together with gravity and deep marine reflection profiling data along the Vulcan transect in northern Australia, define the crustal-scale features between the Precambrian Australian craton and the Timor Trough. The transect provides an outline of crustal and upper mantle architecture across the major boundary between the Australian and SE Asian plates when linked with earlier deep marine seismic profiling. Near the Australian coast, relatively unaltered Precambrian Kimberley Basin rocks are inferred to extend to the edge of a shallow-water shelf area (Yampi Shelf) with a crustal thickness of 35 km. The crust then thins to 26 km under the outer shelf near the Timor Trough. Over the same distance Palaeozoic/Mesozoic basin sequences are interpreted to thicken to 12-13 km, inferring an attenuation of Precambrian basement rocks from 35 to 13-14 km across the margin (ÃŸ=2.6).

On the outer shelf, the Vulcan Sub-Basin is a trans-tensional rift within Permo-Triassic platform areas (Ashmore Platform, Londonderry High). Within the lower crust under major bounding faults at the sub-basin/platform margins, there are elevated P-wave velocities to 7 km/s, suggesting emplacement of intrusive, more mafic rocks at depth during basin-forming processes. At mid-crustal levels, near the top of the inferred attenuated Precambrian crustal rocks, there are strong near-vertical-incidence reflections at about 13 km depth that are interpreted to be a detachment or further evidence of intrusive rocks. Additionally, seismic energy reflected at wide angles from within the upper mantle at 38-45 km depth indicates that compositional boundaries/heterogeneities continue at depth.

Formation, Morphology and Preservation of High-energy Carbonate Lithofacies: Evolution of the Cool-water Recherche Archipelago Inner Shelf, South-western Australia

Cool-water carbonate environments may be responsible for up to one third of the carbonate sediment produced on continental shelves, and are useful modern analogues for many geologically ancient deposits. The extensive southern margin of the Australian continent is recognised as the world's largest modern example of a high energy, cool-water carbonate depositional realm. A number of studies have suggested that Quaternary sediment production here is largely influenced by oceanography, and that wave abrasion strongly limits sediment accumulation. Therefore, in this region the outer-shelf, below the storm wave base, is thought to be the focus of sediment accumulation. The inner shelf is considered a zone of active sediment production due to the proliferation of carbonate secreting organisms, although few studies have investigated sediment production or accumulation in this energetic and dynamic environment. The Recherche Archipelago, which sits at the western margin of the Great Australian Bight (GAB), was examined to better understand Quaternary shelf evolution and the importance of this type of inner shelf as a carbonate 'factory'. Surficial sediments, video, multibeam sonar data, cores and shallow seismics were collected. The present seabed of the archipelago features extensive areas where flat-lying limestones sit over the often irregular granite basement. The Pleistocene erosional surface is overlain by a coarse bivalve and rhodolith dominated gravel lag. Significantly, there are extensive Holocene deposits, up to 7 m thick, throughout the archipelago, particularly in association with granite islands. These deposits comprise cross-bedded gravelly carbonate sands dominated by fragments of calcareous algae (rhodoliths), molluscs and bryozoans. In contrast, the inshore and coast is dominated by terrigenous sediment. Seismic profiles and preserved palaeo-shoreline features suggest that slow but episodic aggradation of marine sediment has occurred on the inner shelf over successive Quaternary sea level cycles, although there are also extensive areas of non-deposition. This accumulation is partly attributable to the sheltering effect of high-relief granitic outcrops and cementation of subaerially exposed carbonate sediments.

Bowen Basin hydrogeological inventory

This Bowen Basin dataset contains descriptive attribute information for the areas bounded by the relevant spatial groundwater feature in the associated Hydrogeology Index map. Descriptive topics are grouped into the following themes: Location and administration; Demographics; Physical geography; Surface water; Geology; Hydrogeology; Groundwater; Groundwater management and use; Environment; Land use and industry types; and Scientific stimulus.

The Bowen Basin is part of the Sydney–Gunnedah–Bowen basin system and contains up to 10,000 m of continental and shallow marine sedimentary rocks, including substantial deposits of black coal. The basin's evolution has been influenced by tectonic processes initiated by the New England Orogen, commencing with a phase of mechanical extension, and later evolving to a back-arc setting associated with a convergent plate margin. 

Three main phases of basin development have been identified; 1) Early Permian: Characterized by mechanical extension, half-graben development, thick volcanic units and fluvio-lacustrine sediments and coal deposits. 2) Mid Permian: A thermal relaxation event led to the deposition of marine and fluvio-deltaic sediments, ending with a regional unconformity. 3) Late Permian and Triassic: Foreland loading created a foreland basin setting with various depositional environments and sediment types, including included fluvial, marginal marine, deltaic and marine sediments along with some coal deposits in the late Permian, and fluvial and lacustrine sediments in the Triassic. Late Permian peat swamps led to the formation of extensive coal seams dominating the Blackwater Group. In the Triassic, fluvial and lacustrine deposition associated with foreland loading formed the Rewan Formation, Clematis Sandstone Group, and Moolayember Formation. The basin is a significant coal-bearing region with over 100 hydrocarbon accumulations, of which about one third are producing fields. The Surat Basin overlies the southern Bowen Basin and contains varied sedimentary assemblages hosting regional-scale aquifer systems. 

Cenozoic cover to the Bowen Basin includes a variety of sedimentary and volcanic rock units. Palaeogene and Neogene sediments mainly form discontinuous units across the basin. Three of these units are associated with small eponymous Cenozoic basins (the Duaringa, Emerald and Biloela basins). Unnamed sedimentary cover includes Quaternary alluvium, colluvium, lacustrine and estuarine deposits; Palaeogene-Neogene alluvium, sand plains, and duricrusts. There are also various Cenozoic intraplate volcanics across the Bowen Basin, including central volcanic- and lava-field provinces.

Summary of Analyses undertaken on debris recovered during the search for flight MH370

On 8 March 2014, the Boeing 777-200ER aircraft registered as Malaysia Airlines 9M-MRO and operating as flight MH370 (MH370) disappeared from air traffic control radar after taking off from Kuala Lumpur, Malaysia on a scheduled passenger service to Beijing, China with 227 passengers and 12 crew on board.

After analysis of satellite data it was discovered that MH370 continued to fly for over six hours after contact was lost. All the available data indicates the aircraft entered the sea close to a long but narrow arc of the southern Indian Ocean.

On 31 March 2014, following an extensive sea and air search, the Malaysian Government accepted the Australian Government’s offer to take the lead in the search and recovery operation in the southern Indian Ocean in support of the Malaysian accident investigation.

On behalf of Australia, the Australian Transport Safety Bureau (ATSB) coordinated and led the search operations for MH370 in the southern Indian Ocean. Geoscience Australia provided advice, expertise and support to the ATSB in sea floor mapping (bathymetric survey) and the underwater search. GA has also provided quarantine facilities for receipt of possible debris, and has undertaken laboratory analyses for a number of these pieces. This record is a collation of reports describing quarantine procedures and parts analysis undertaken by Geoscience Australia for some of the debris recovered and processed through Geoscience Australia laboratories during the search for flight MH370.

Exmouth Gulf Marine Seismic Survey Western Australia, 1961 By West Australian Petroleum Pty Limited

A reconnaissance marine reflection seismic survey was conducted hi Exmouth Gulf and the open coastal waters along the west coast of Western Australia from Frazer Island to Bernier Island (see Fig. 1).

The survey was a two-boat operation. The survey in the Exmouth Gulf area was controlled by a Lorac radio navigational system, and along the west coast positioning was determined by sextant angle measurements to shore beacons and landmarks. All shots were recorded on magnetic tapes which were processed into variable area record sections.

The following maps were constructed:
(i) On a Horizon "A" within the Upper Cretaceous Korojon Calcarenite (Exmouth Gulf area only);
(ii) On a Horizon "B" near the Basal Cretaceous unconformity; 
(iii) On pre-Cretaceous structure;
(iv) Time interval between Horizons "A" and "B" (Exmouth Gulf area only);
(v) Depth of water.

The Exmouth marine survey indicated that Exmouth Gulf is essentially synclinal in character in the Cretaceous and Tertiary sediments. Several major pra-Cretaceous fault trends which had already been mapped on land with the seismograph were followed beneath the Gulf. The pre-Cretaceous axis of the Cape Range Anticline was located both to the north and to the south of the surface expression of the structure. The chain of islands to the north-east of the Ca.pe Range are aligned on a structural trend.

To the south of-Point Maud, the Cuvier marine survey provided a much-needed tie between the Rough Range-Cape Range area and the structurally complex area around the Salt Marsh. Some structural leads were found in this southern area and the trend of major faults was established.

The application of physical surrogates as tools for benthic habitat mapping: An evaulation of techniques

The identification of marine habitats based on physical parameters is increasingly important for marine reserve design, allowing characterisation of habitat types over much wider areas than is possible from often patchy biological data. Marine management zones often contain a wide array of physical environments, which may not be captured in the biological sampling effort. The mismatch between biological and physical information leads to uncertainty in the application of bio-physical relationships at the broader management scale. In this study, a case study from northern Australia is used to demonstrate a methodology for defining uncertainties which result from the extrapolation of bio-physical associations across areas where detailed biological data is absent. In addition, uncertainties relating to the interpolation of physical data sets and that resulting from the cluster analysis applied to the physical data are calculated and mapped, providing marine managers with greater robustness in their analysis of habitat distributions.
