Survey of the extent of Macrocystis pyrifera beds in the vicinity of the Mercury Passage, east coast of Tasmania, 1965

A research program jointly conducted by Alginates (Australia) P/L and C.S.I.R.O. Division of Fisheries and Oceanography was set up to investigate the relationship between kelp: Macrocystis pyrifera (Linnaeus) C. Agardh 1820 and crayfish larvae. Alginates (Australia) P/L, based at Louisville in the Mercury Passage, were harvesting kelp at this time. This study was initiated to address concerns regarding the effect of harvesting on crayfish stocks.

The survey results are taken from an unpublished interim report presenting the results of the work at that stage (1965).

Apparently an aerial survey was used to determine stock distributions although this is not specified in the report.

National Gravity Compilation 2019 Ausdrape elevation geoid image (hillshade HSI)

Digital Elevation data record the terrain height variations from the processed SRTM surface elevation 3 second grid data with a drape surface overlain. This National Gravity Compilation 2019 Ausdrape elevation geoid image (hillshade HSI) is elevation data for the 2019 Australian National Gravity Grids B series. These data are used in the project No. 202008. The grid used to produce this image has a cell size of 0.00417 degrees (approximately 435m). All data (i.e., ground, airborne and marine derived from satellite altimetry) were vertically continued to this surface during processing. The surface was generated to mimic a smooth airborne survey drape surface with a minimum surface clearance of 250 m and an isotropic maximum climb and descent rates of 25 m per km. The ground surface data were derived from SRTM data with 3 second grid cell size. The data are given in units of meters. The data are given in units of meters.

Effect of nutrient loading on biogeochemical processes in tropical tidal creeks

The effect of increased nutrient loads on biogeochemical processes in macrotidal, mangrove-lined creeks was studied in tropical Darwin Harbour, Australia. Water quality and sediment composition, benthic and pelagic metabolism and benthic nutrient and gas fluxes were studied during three field surveys to compare nutrient transformation and retention processes in three tidal creeks receiving different loads of sewage discharge. There were marked differences in process rates between Buffalo Creek (hypertrophic), which receives the largest sewage loads; Myrmidon Creek (oligotrophic-mesotrophic) which receives smaller sewage inputs; and Reference Creek (oligotrophic) which is comparatively pristine. Net benthic nutrient fluxes in Buffalo Creek were more than an order of magnitude higher than in Myrmidon and Reference Creeks, which have similar and low benthic fluxes during the wet and dry seasons. Similarly, net pelagic primary production rates were much higher in Buffalo Creek and respiration exceeded primary production resulting in severe drawdown of O2 concentrations at night. In Buffalo Creek, anoxic sediments released oxide-bound phosphorus and inhibited coupled nitrification-denitrification, enhancing benthic nitrogen and phosphorus fluxes. Light limitation of primary production resulted in build-up of excess nutrients in the water column, further stimulating primary production. Poor water quality in Buffalo Creek was exacerbated by poor tidal flushing imposed by a narrow meandering channel and sandbar across the mouth. In contrast to Buffalo Creek, the effect of the sewage load in Myrmidon Creek was confined to the water column, and the impact was temporary and highly localized. This study has identified pelagic primary production, benthic nutrient fluxes and denitrification efficiency as the biogeochemical processes most affected by nutrient loading in tidal creek systems. The serious deterioration of water quality impacts on the functioning of the whole ecosystem, with potential for detrimental effects on higher trophic levels.

McArthur Basin hydrogeological inventory

This McArthur 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 McArthur Basin, located in the north-east of the Northern Territory, is a Paleoproterozoic to Mesoproterozoic geological formation containing relatively undisturbed siliclastic and carbonate rocks, as well as minor volcanic and intrusive rocks. These sediments were primarily deposited in shallow marine environments, with some lacustrine and fluvial influences.

The basin's thickness is estimated to be around 10,000 m to 12,000 m, potentially reaching 15,000 m in certain areas. It is known for hosting elements of at least two Proterozoic petroleum systems, making it a target for petroleum exploration, especially in the Beetaloo Sub-basin.

Researchers have divided the McArthur Basin into five depositional packages based on similarities in age, lithofacies composition, stratigraphic position, and basin-fill geometry. These packages, listed from oldest to youngest, are the Wilton, Favenc, Glyde, Goyder, and Redback packages.

The McArthur Basin is part of the broader Proterozoic basin system on the North Australian Craton, bounded by various inliers and extending under sedimentary cover in areas like the Arafura, Georgina, and Carpentaria basins. It is divided into northern and southern sections by the Urapunga Fault Zone, with significant structural features being the Walker Fault Zone in the north and the Batten Fault Zone in the south.

The basin's southeastern extension connects with the Isa Superbasin in Queensland, forming the world's largest lead-zinc province.

Overall, the McArthur Basin is an essential geological formation with potential petroleum resources, and its division into distinct packages helps in understanding its complex stratigraphy and geological history. Additionally, its connection with other basins contributes to a broader understanding of the region's geological evolution and resource potential.

Four-dimensional connectivity modelling with application to Australia's north and northwest marine environments

A fully four-dimensional (3D × time) object-oriented biophysical dispersal model was developed to simulate the movement of marine larvae over semi-continuous surfaces. The model is capable of handling massive numbers of simulated larvae, can accommodate diverse life history patterns and distributions of characteristics, and saves point-level information to a relational database management system. The model was used to study Australia's northwest marine region, with attention given to connectivity patterns among Australia's north-western Commonwealth Marine Reserves (CMRs). Animations of larval movement near the Gascoyne canyon CMR, dispersal surfaces over depth and time for CMRs and Key Ecological Features in the northwest, as well as matrices of connectivity values among CMRs are shown. The matrices are further analysed to identify the sensitivity and elasticity of their values. The results generated by this model can aid in designing and managing marine protected area networks that incorporate extensive and complex benthic terrain (including the identification of marine ‘corridors’), and for developing targeted field sampling strategies.

Seabed geomorphology and habitat mapping to support the sustainable development of offshore renewable energy in Australia

Australia’s vast marine estate offers high-quality offshore wind resources that have the potential to help produce the renewable energy that Australia will need to achieve its net zero emissions targets. Mature offshore renewable industries in Europe have demonstrated that marine geoscience is critical for supporting the sustainable development, installation, operation and decommissioning of offshore wind farms. Geoscience information is used to design targeted seabed surveys and identify areas suitable for offshore infrastructure, thereby reducing uncertainty and investment risk. These data also provide important regional context for environmental impact assessments and informs evidence-based decisions consistent with government policies and regulations. Effective geomorphic characterisation of the seabed requires a standardised, multi-scalar and collaborative approach to produce definitive geomorphology maps that can support these applications. These maps synthesise interpretations of bathymetry, shallow geology, sedimentology and ecology data, to illustrate the distribution and diversity of seabed features, compositions and processes, including sediment dynamics and seabed stability. We present mapped examples demonstrating the utility of a nationally consistent seabed geomorphology mapping scheme (developed in collaboration with European agencies), for application to a broad range of geographic settings and policy-needs, including the sustainable development of offshore renewable energy in Australia.

A field guide to basin architecture and crustal evolution in the Paleoproterozoic-earliest Mesoproterozoic sequences of Mount Isa, northern Australia: a record of (Nuna) supercontinent breakup

Paleoproterozoic-earliest Mesoproterozoic sequences in the Mount Isa region of northern Australia preserve a 200 Myr record (1800-1600 Ma) of intracontinental rifting, culminating in crustal thinning, elevated heat flow and establishment of a North American Basin and Range-style crustal architecture in which basin evolution was linked at depth to bimodal magmatism, high temperature-low pressure metamorphism and the formation of extensional shear zones. This geological evolution and record is amenable to investigation through a combination of mine visits and outcrop geology, and is the principal purpose of this field guide.

Rifting initiated in crystalline basement -1840 Ma old and produced three stacked sedimentary basins (1800-1750 Ma Leichhardt, 1730-1670 Ma Calvert and 1670-1575 Ma Isa superbasins) separated by major unconformities and in which depositional conditions progressively changed from fluviatile-lacustrine to fully marine. By 1685 Ma, a deep marine, turbidite-dominated basin existed in the east and basaltic magmas had evolved in composition from continental to oceanic tholeiites as the crust became increasingly thinned and attenuated. Except for an episode of minor deformation and basin inversion at c. 1640 Ma, sedimentation continued across the region until onset of the Isan Orogeny at 1600 Ma.

Report on a geological survey of Commonwealth Territory, Jervis Bay

This report is based on field work at Jervis Bay and in the surrounding area during the period 4th to 30th June, 1952. The purpose of the investigation was primarily economic, though no further attention was given to the deposit of firebrick clay previously described (Smith et al., 1948). Outcrops in the Commonwealth Territory at Jervis Bay consist almost entirely of sandstone of Permian age. The name Jervis Bay Sandstone is proposed for these rocks, which have been found to underlie the Wandrawandian Siltstone, and are tentatively correlated with the Conjola beds - all units of the Shoalhaven Group, which includes part of the former Upper Marine Series. Marine fossils having affinity with those found in the former Upper Marine Series have been found in the Jervis Bay rocks. The sandstones have been invaded in a few places by basic intrusive rocks, probably during the Tertiary Period. The only materials of economic significance found in the Territory are firebrick clay, and ferruginous gravel useful for surfacing roads. Additional supplies of the ferruginous gravel may occur in the areas delineated on the map as suitable for further prospecting.

Lower Carboniferous spores from the Bonaparte Gulf Basin, Western Australia and Northern Territory

Well preserved assemblages of plant microfossils have been recovered from Lower Carboniferous sediments - principally or entirely marine in origin and Visean in age encountered in four boreholes in the landward Bonaparte Gulf Basin of Western Australia and Northern Territory. The sediments are representative of the following lithostratigraphic units: Bonaparte Beds (upper portion) and overlying Tanmurra Formation (intersected by Bonaparte Nos 1 and 2 Wells, central basinal province of Bonaparte Gulf Basin, Western Australia); Milligans Beds (Spirit Hill No. 1 Well; Spirit Hill and Milligans No. 1 Bores, all located in the southeastern platform region of the basin, Northern Territory) and overlying Burvill Beds (basal portion) of Milligans No. 1 only. The 55 species of plant microfossils recognized are distributed among 32 genera of trilete sporae dispersae, including one new genus, Exallospora, which is instituted for the reception of distally annulate cingulate forms having typically verrucate sculptural elevations. Twenty-two species are referable (six tentatively so) to previously established taxa. The palynological flora is dominated by the pan-Australian, Famennian to ?mid-Carboniferous species Granulatisporites frustulentus Balme, Hassell (emended herein), which accounts for 44-83 percent of the spore populations. Certain (inevitably subordinate) spore forms, either the same as or closely similar to species known from northern hemisphere Lower Carboniferous sediments, lend confirmation to the Visean age previously adduced from the contained fauna.

Perth Canyon Marine Park Bathymetry - 40m 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°).

The palaeogeography of the Bass Strait land-bridge, a vital zone of human and biological connectivity across southeastern Australia

Land-bridges are key regions of human connectivity, yet how geography affected peoples' movement during flooding is poorly understood. Bass Strait is one of the most important land-bridges in Australasia, separating Lutruwita/Tasmania from the mainland of Australia. The land-bridge forms a key part of Country among the region's First Peoples, with people able to move across the clan estates and residential places of the exposed Bass Strait by foot until its flooding after the Last Ice Age. In this study, we utilise high-resolution bathymetry to understand landscape change during sea-level rise. We find that rates of shoreline transgression can exceed 30&nbsp;m/yr, signalling that 15 km of land would have been drowned in a persons lifetime. This rapid rate of change is within a person's life-span and would have profoundly affected individuals as they resided in and travelled across Country. We also find that people first crossed the land-bridge very soon after its exposure during climate cooling events. The analysis provides a benchmark for understanding land-bridge flooding and in turn its impact on human migrations.
