Seabed Character Mapping in the Great Australian Bight

This report presents the results of a regional seafloor mapping study carried out during 2000/2001 as part of Geoscience Australia's South and Southwest Regional Project. The aim was to support future Regional

Marine Planning in the Great Australian Bight (GAB) by underpinning biological, environmental and
economic assessments with basic information on geomorphology and the seabed character.
Four major geomorphological features are present on the margin in the South and Southwest (SSW) region: a continental shelf, marine terraces (including the Eyre and Ceduna Terraces in the GAB), a continental slope and a continental rise. The boundaries of these geomorphological features have been delineated and captured in a Geographical Information System (GIS). The GIS also includes the location of sedimentary basins, plateaus, terraces and canyons previously mapped in the region.
Seabed character mapping was carried out for the GAB area only. Five echo facies have been defined in the GAB area based on the interpretation of available 3.5kHz echo-sounding records and high-resolution seismic profiles in terms of acoustic facies, and their groundtruthing against seafloor samples. The interpretation of these facies has been digitised and captured into a GIS. The GIS includes key attributes for every echo facies. The acoustic facies distribution on the GAB margin and offshore in the South Australian abyssal plain shows the importance of geological inheritance to the geomorphology and sea-bed character of the region.

Facies I, which represents undisturbed, layered sediments is mainly localised on the shelf, the Eyre and Ceduna Terraces, and in the greater part of the abyssal plain. Facies II, which may represent more disturbed sediments, is confined to the Ceduna Terrace and along two elongated E-W trending areas on the abyssal plain near the continent-ocean boundary. Facies III, associated with extreme (IIIA), moderate (IIIC) and low (IIID) topography, underlies scarps, canyons, and depressions on the continental slope and the abyssal plain.

The distribution of acoustic facies from the upper slope down to the abyssal plain indicates that the major sedimentary process in the deep water GAB is deposition of pelagic sediments. Reworking of sediments by both bottom currents and gravity flows is probably limited to submarine canyons.

Suspended-sediment transport and water movement at One Tree Reef, southern Great Barrier Reef

One Tree Reef, in the southern Great Barrier Reef, is roughly triangular, with the southeast corner forming the windward margin, and the northwest side the leeward margin. In March/April 1979, water circulation and sediment flux were monitored over the reef margins. Generally, water moving from the ocean across the perimeters decreases in velocity when it reaches the lagoon. Over the windward margin coral and algal flats, water movement patterns are similar; i.e., in both environments flow reversal characterises the spring tide flood/ebb change, whereas on neaps, flow is continually towards the lagoon. On the southern prograding sand sheet, between the coral flat and the lagoon, flow is continually towards the lagoon. On the leeward margin, the flood/ ebb flow reversal is again a dominant feature. Sediment flux for the different reef zones reflects the water flows. On the windward algal and coral flats, twice as much sediment leaves the reef towards the ocean on spring tides as is transported to the sand sheets, where there is a net loss; on neaps however, suspended sediment movement is continually towards the sand sheets. On the sand sheets, all sediment flux is towards the lagoon, with twice as much arriving in the springs compared with neaps. Spring tide sediment losses over the leeward margin are greater than neap tide gains made by the lagoon over the same margin. The distribution of mud in the lagoon, its concentration at the leeward margin, and its absence on the sand sheets can be explained by the observed energy pattern. Sediment is lost from the system mainly by spring tide flushing of the lagoon, most sediment leaving over the leeward margin.

Depositional framework of petroleum systems, Browse Basin, offshore North West Shelf, Australia

The Browse Basin is a proven hydrocarbon province hosting gas with associated condensate on Australia’s North West Shelf. Geoscience Australia has undertaken a multi-disciplinary study to identify the various hydrocarbon sources and high-graded areas of increased liquids prospectivity within a primarily gas-prone province. Updated biostratigraphy, well correlations, seismic and paleogeographic and play fairway interpretations were completed for ten Hettangian to Maastrichtian supersequences. These data together with geochemical analyses were integrated into a regional petroleum systems model to better understand source rock distribution, character, generation potential and play prospectivity.
Isochore maps and depositional environmental models suggest multiple source rock units in compartmentalised Jurassic–Cretaceous source pods resulting in four geochemically distinct petroleum systems. Source pod location is influenced by regional basin architecture and entrenched fluvial systems forming a complex network of sedimentary inputs to the basin.
Gas generated by the Lower–Middle Jurassic source rocks within the J10–J20 supersequences (Plover Formation) have migrated through the basin and accumulated at multiple stratigraphic levels. The Jurassic J10–J50 supersequences (Plover and lower Vulcan formations) in the Heywood Graben have generated fluids of a different composition to those elsewhere in the basin, and are most similar to a petroleum system in the neighbouring Bonaparte Basin. Gases with the highest liquid content are reservoired within the K10 supersequence (Brewster Member, Vulcan Formation) in the Ichthys/Prelude and Burnside accumulations. These fluids are probably sourced by shales of the Upper Jurassic–Lower Cretaceous J40–K10 supersequences (Vulcan Formation) encasing the K10 sandstone reservoir. Marine Lower Cretaceous source rocks in the K20–K30 supersequences (Echuca Shoals Formation) have sourced oil and gas in Cretaceous reservoirs of the Caswell Sub-basin and on the Yampi Shelf. The latter accumulations contain a mixture of Cretaceous oil mixed with gas generated by higher maturity Jurassic source rocks. A proposed scenario is that these Cretaceous-sourced liquids were mobilised and carried to the shelf edge by co-migrating Plover-derived gas with subsequent biodegradation and leakage. These results open up shallow liquid-prone plays, in the southern Caswell Sub-basin and on the basin margins.

Life at Cold Seeps: A Synthesis of Biogeochemical and Ecological Data from Kazan Mud Volcano, Eastern Mediterranean Sea

Recent field observations have identified the widespread occurrence of fluid seepage through the eastern Mediterranean Sea floor in association with mud volcanism or along deep faults. Gas hydrates and methane seeps are frequently found in cold seep areas and were anticipated targets of the MEDINAUT/MEDINETH initiatives. The study presented herein has utilized a multi-disciplinary approach incorporating observations and sampling of visually selected sites by the manned submersible Nautile and by ship-based sediment coring and geophysical surveys. The study focuses on the biogeochemical and ecological processes and conditions related to methane seepage, especially the anaerobic oxidation of methane (AOM), associated with ascending fluids on Kazan mud volcano in the eastern Mediterranean. Sampling of adjacent box cores for studies on the microbiology, biomarkers, pore water and solid phase geochemistry allowed us to integrate different biogeochemical data within a spatially highly heterogeneous system. Geophysical results clearly indicate the spatial heterogeneity of mud volcano environments. Results from pore water geochemistry and modeling efforts indicate that the rate of AOM is 6 mol m-2 year-1, which is lower than at active seep sites associated with conditions of focused flow, but greater than diffusion-dominated sites. Furthermore, under the non-focused flow conditions at Kazan mud volcano advective flow velocities are of the order of a few centimeters per year and gas hydrate formation is predicted to occur at a sediment depth of about 2 m and below. The methane flux through these sediments supports a large and diverse community of micro- and macrobiota, as demonstrated by carbon isotopic measurements on bulk organic matter, authigenic carbonates, specific biomarker compounds, and macrofaunal tissues...

Open Space

The Victorian Planning Authority has developed a comprehensive GIS dataset to represent the existing open space network throughout the metropolitan Melbourne area. 

This data builds upon the work completed through the Victorian Environmental Assessment Council’s (VEAC) Metropolitan Melbourne Investigation (2011), as well as GIS data provided by Melbourne’s 32 metropolitan councils and a variety of other agencies.

The data includes public open space, restricted public land and some private open space - suitable for a range of spatial mapping and analysis purposes. 

In order to truly reflect the range of land types as well as the diversity of functions and roles open space plays, a multi-tiered definition of open space was developed. This updated definition builds upon previous work done by VEAC, as well as a number of local government open space strategies. This updated definition is supported by a hierarchy and categorisation system that can be applied to the entire network.  

The resultant data show an open space network that includes a significant range of land uses, from the obvious local parks, sports fields and waterways, through to schools and utility easements. It is recognised however, that not all land shown has the same open space function, value or access level and the primary function of the land (restricted public land and private open space) will often impact on its existing or future potential community use.

The Open Space data is NOT currently being maintained.

Unplanned Disruptions - Road

This API contains details of unplanned disruptions in near real-time on roads managed by the Victorian Department of Transport and Planning as well as roads managed by local councils. The data includes the location and reason for the disruption along the road it has occurred on, number of lanes closed, enhanced public advice for consumers, and improved accuracy for an incident’s location.

Also included are Tow Truck allocations within the Melbourne Controlled Area (including Mornington Peninsula) which is done by the Accident Allocation Centre, managed under contract to the DTP. The records either represent a road disruption affecting either a point on a road or a length of road or tow trucks in the Melbourne Controlled Area attending an accident scene for vehicles with a gross vehicle mass less than 4 tonnes only after receiving an allocation number.

Data is collected from the Road Incident Database (RID) system managed by the Victorian Transport Operations Centre (TOC) as well as Probe, a 3rd party organisation that helps to manage tow allocations data for the Department.

This API uses a Parent-Child relationship within its records. See example below.

Comment on Dye (2006) - "Is Geomorphic Zonation a Useful Predictor of Patterns of Benthic Infauna in Intermittent Estuaries in New South Wales, Australia?"

In a recent paper, Dye (2006) analyzed the distribution of species of macrobenthos and meiobenthos
within two geomorphic facies of four small intermittently closed and open estuaries in New South Wales, Australia (colloquially known as ICOLLs). We believe that Dye's (2006) study is not an appropriate test of the Roy et al. (2001) habitat classification, and consequently several of the
hypotheses posed by Dye do not follow logically from their model.

Shellharbour seabed landforms derived from multibeam echosounder data 2022

Mulitbeam echosounder (MBES) bathymetry data were collected offshore of Shellharbour, NSW in 2017. Bathymetry data coverage extends from Port Kembla to Bass Point, and ranges from 10 to 64 m water depth. This dataset represents a classification of seabed landforms derived from this MBES, which delineates the prominent seabed features observed. This classification defines areas of reefs, peaks, plains, scarps, depressions and channels. Features were classified using the Seabed Landforms Classification Toolset developed for ArcGIS by the Coastal and Marine Unit, DPE (Linklater et al. 2023) which are publicly available on SEED (https://datasets.seed.nsw.gov.au/dataset/seabed-landforms-classification-toolset) and GitHub (https://github.com/LinklaterM/Seabed-Landforms-Classification-Toolset/).

A preliminary classification of this Shellharbour survey was presented in Kinsela et al. (2020), and this classification represents the final interpreted product for this survey. This dataset contributes toward an understanding of the distribution of submerged reefs along the NSW coast, which provides fundamental baseline information for managers, users and custodians of the marine environment. 

The source MBES dataset for this classification is available on the Australian Ocean Data Network portal: https://portal.aodn.org.au/

FireTools Cloud Results - NPWS Greater Sydney Branch

FireTools Cloud is a web-based GIS processing environment developed by the NSW Bushfire Risk Management Research Hub, a NSW focused research partnership between the NSW Department of Planning, Industry and Environment, the University of Wollongong, Western Sydney University, the University of NSW, the University of Tasmania, the University of Melbourne and the NSW Rural Fire Service. It is designed to replicate and replace the functionality of the FireTools II ArcGIS processing plugin to assist in fire management planning. Users upload a datapack containing the GIS files used to run a standard FireTools II analysis, configure the layers and fields that define the analysis, and submit the analysis for processing. After processing is complete, users can download a results pack containing GIS files with analysis results. Selected results are distributed for use as described below.

Results are true and correct only for the reserves within the NPWS Greater Sydney Branch. Fire history outside the reserves is incomplete so results should not be relied upon.

Layers in this data package:
Heritage threshold status: Input vegetation classified into LongUnburnt, WithinThreshold, Vulnerable, TooFrequentlyBurnt, Unknown and NoFireRegime (raster and vector). This layer is used to monitor the status of vegetation across the study area with respect to its biodiversity-related impacts of fire.

Number of times burnt: The number of times any given point within the study area has been intersected by a burnt area polygon in the fire history (raster and vector)

Time Since Last Fire: The number of years since any given point within the study area has been intersected by a burnt area polygon in the fire history (raster and vector)

Time Since Last Fire SFAZ: The number of years since any given Strategic Fire Advantage Zone (SFAZ) within the study area has been intersected by a burnt area polygon in the fire history. This is then classified into 3 time slices whereby 0-6 years = Recently Treated, 7-10 years = Monitor OFH in the field and &gt;10 years = Priority for Assessment and Treatment. (raster and vector). This layer is used to find candidate burn blocks to assess for addition into a hazard reduction program of works.

Vegcode: A simple display layer showing the input vegetation groups over the study area. This is not a fully attributed vegetation layer – it is designed as a simple visual (raster only).

VegBase: This is a copy of the input veg used, showing just the VEG code, MIN, MAX. Can be used to analyse what is driving results in a given location.

Data is updated up to 4 times per year.
