Geographe Marine Park Bathymetry - 5m Resolution Grid

Australia has established a network of 58 marine parks within Commonwealth waters covering a total of 3.3 million square kilometres, or 40 per cent of our exclusive economic zone (excluding Australian Antarctic Territory). These parks span a range of settings, from near coastal and shelf habitats to abyssal plains. Parks Australia manages the park network through management plans that came into effect for all parks on 1 July 2018. Geoscience Australia is contributing to their management by collating and interpreting existing environmental data, and through the collection of new marine data.  “Eco-narrative” documents are being developed for those parks, where sufficient information is available, delivering collations and interpretations of seafloor geomorphology, oceanography and ecology. Many of these interpretations rely on bathymetric grids and their derived products, including those in this data release.

Bathymetry grids:
The bathymetry of the marine parks was created by compiling and processing Geoscience Australia’s bathymetry data holding gridded at the optimum resolution depending of the vessel’s sonar system.
The bathymetry of the park is illustrated by a panchromatic geotiff image, developed by combining the bathymetric data with a hillshade image.

Morphological Surfaces:
Geoscience Australia has developed a new marine seafloor classification scheme, which uses the two-part seafloor mapping morphology approach of Dove et al (2016). This new scheme is semi-hierarchical and the first step divides the slope of the seafloor into three Morphological Surface categories (Plain, &lt;2°; Slope, 2-10°; Escarpment, &gt;10°).

Predicted seabed gravel, mud and sand content in the Timor Sea region in the Australian continental EEZ 2018

This dataset provides the spatially continuous data of seabed gravel (sediment fraction &gt;2000 µm), mud  (sediment fraction &lt; 63 µm) and sand content (sediment fraction 63-2000 µm) expressed as a weight percentage ranging from 0 to 100%, presented in 10 m resolution raster grids format and ascii text file. 

The dataset covers the eight areas in the Timor Sea region in the Australian continental EEZ.

This dataset supersedes previous predictions of sediment gravel, mud and sand content for the basin with demonstrated improvements in accuracy. Accuracy of predictions varies with sediment types, with a VEcv = 71% for mud, VEcv = 72% sand and VEcv = 42% for gravel. Artefacts occur in this dataset as a result of noises associated predictive variables (e.g., horizontal and vertical lines resulted from predictive variables derived from backscatter data are the most apparent ones). To obtain the most accurate interpretation of sediment distribution in these areas, it is recommended that noises with backscatter data should be reduced and predictions updated.

Seawater microbiome responses to copper across reef environments

This data collection consists of water quality measurements, nutrient data and measured copper concentrations associated with experiments that derived site-specific guidline values (GVs) for tropical seawater microbiomes by integrating 16S rRNA gene amplicon sequencing with quantitative microbiome profiling and concentration-response modelling. Seawater was collected during high tide at three target sites adjacent to the Burdekin region of the Great Barrier Reef, representing varying disturbance histories:  (1) Davies Reef, a high ecological value (HEV) coral reef reference site (S 18&deg;49.826&rsquo; E 147&deg;38.177&rsquo;) situated 50 km offshore with low levels of human impacts and part of the Marine Protected Area; (2) Magnetic Island, a slightly  to moderately disturbed (SD-MD) inshore coral/algal reef site (S 19&deg;09.279&rsquo; E 146&deg;52.108&rsquo;) with some perturbations from shipping traffic, dredging, industry, and agricultural runoff; (3) Townsville Breakwater in close proximity to the Port of Townsville, a highly disturbed (HD) inshore site (S 19&deg;14.629&rsquo; E 146&deg;49.989&rsquo;) with increased influence from shipping traffic, industry, and urban runoff. Seawater from each site was subsequently used in a 48-h copper exposure experiment. Water quality measurements (dissolved oxygen, pH and salinity) and water samples for nutrients (dissolved organic / inorganic carbon and nitrogen) were taken at 0-h and 48-h, following standard AIMS procedures. Representative water samples from the nominal experimental treatments (0, 0.1, 0.3, 1, 3, 10, 30, 60, 100, 300, 1000, 3000, 8000 &mu;g Cu L-1) were sent to Envirolab for dissolved copper quantification. Data was entered into excel.

Marine Futures Project - Mount Gardner - biota

The Marine Futures Project was designed to benchmark the current status of key Western Australian marine ecosystems, based on an improved understanding of the relationship between marine habitats, biodiversity and our use of these values. Approximately 1,500 km2 of seafloor were mapped using hydroacoustics (Reson 8101 Multibeam), and expected benthic habitats "ground-truthed" using towed video transects and baited remote underwater video systems. Both sources of information were then combined in a spatial predictive modelling framework to produce fine-scale habitat maps showing the extent of substrate types, biotic formations, etc.

Surveys took place across 9 study areas, including Mount Gardner, a site located just off Two People’s Bay, 30km east of the town of Albany. The area is host to a number of human uses, including recreational and commercial fishing, diving, surfing, recreational boat use and shipping and mining. The marine environment at this location is different to the other three study locations on the south coast, in that it encompasses the protected Two Peoples Bay with seagrass and invertebrate communities and the more exposed rocky and macroalgal reefs around the Mt Gardner peninsula itself.

Ecosystem characterisation of Australia's North West Shelf

Habitats serve a variety of functions on the North West Shelf (NWS). They support the life history stages of a diverse suite of tropical species including commercially harvested ones. In addition to natural disturbance regimes, habitats are altered in response to the sectoral uses, which in turn affects the distribution and life histories of species. Habitats thus serve as the nexus linking species with uses and natural disturbance, and different habitats serve different purposes at various stages of the life history of a species. A detailed understanding of habitats, at least at the structural level, is thus a prerequisite for a more comprehensive understanding of ecological structure and functions on the North West Shelf.

This component of the North West Shelf Joint Environmental Management Study (NWSJEMS) aimed to collate and integrate data on habitats for the region of the North West Shelf extending from North West Cape to Port Hedland and from the coast to the 200 m isobath. The three main activities of the study were:  Development of an integrated collection of information on habitats of the North West Shelf, including expert information;  Application of the CSIRO Habitat Classification Framework to the data to determine the spatial nesting and structuring of habitat units on the North West Shelf; and  Provision of the habitat structure classification for input into other models developed within NWSJEMS.

This record describes data of key benthic marine ecosystems and habitats. These maps and descriptions of their component attributes were designed to assist the process modelling of the ecosystem and impacts of uses, as well as directly supporting planning and management by Western Australian agencies and industries.

Elizabeth and Middleton Reef multibeam sonar backscatter survey (GA4848)

This resource includes multibeam sonar backscatter data for Middleton Reef and Elizabeth Reef within Lord Howe Marine Park collected by Geoscience Australia during the period 31 January to 6 February 2020 on the Australian Maritime College vessel, TV Bluefin. The survey was undertaken as a collaborative project funded through the National Environmental Science Program Marine Biodiversity Hub, with the Institute for Marine &amp; Antarctic Studies (University of Tasmania), NSW Department of Primary Industries, University of Sydney (Australian Centre for Field Robotics) and Parks Australia (Marine Park managers, Commonwealth Government). The purpose of the survey was to collect baseline information for benthic habitats within the National Park Zone (Middleton Reef) and Recreational Use Zone (Elizabeth Reef) of the marine park. These data will support ongoing environmental monitoring within the Temperate East Marine Park Network as part of its 10-year management plan (2018-2028). Data acquisition for the project included seabed mapping using multibeam sonar (Kongsberg EM 2040C HD, 300 kHz), seabed imagery acquisition by Autonomous Underwater Vehicles (AUV Sirius and AUV Nimbus), sediment samples (grab) and imagery of demersal fish communities by baited remote underwater videos (BRUVs). This dataset comprises two bathymetry grids derived from multibeam sonar data gridded at 4 mspatial resolution. A detailed report on the survey is available on the Marine Biodiversity Hub’s website (https://www.nespmarine.edu.au/reports;  Carroll, A et al., 2020,.
