Oceanic Shoals Commonwealth Marine Reserve - Pelagic baited camera surveys (stereo-BRUVS)

This dataset derives from deployments of pelagic baited camera systems (stereo-BRUVS) conducted within the Oceanic Shoals Commonwealth Marine Reserve (CMR) in the Timor Sea during September and October 2012 onboard the RV Solander.

This resource comprises species lists and relative abundance data (measured as MaxN, the maximum number of individuals of a given species captured in any one frame) for 116 sampling sites surveyed across three focal areas.

The Oceanic Shoals Commonwealth Marine Reserve survey was undertaken as an activity within the Australian Government's National Environmental Research Program Marine Biodiversity Hub and was the key component of Research Theme 4 - Regional Biodiversity Discovery to Support Marine Bioregional Plans. Hub partners involved in the survey included the Australian Institute of Marine Science, Geoscience Australia, the University of Western Australia, Museum Victoria and the Museum and Art Gallery of the Northern Territory. Data acquired during the survey included: multibeam sonar bathymetry and acoustic backscatter; sub-bottom acoustic profiles; physical samples of seabed sediments, infauna and epibenthic biota; towed underwater video and still camera observations of seabed habitats; baited video observations of demersal and pelagic fish, and; oceanographic measurements of the water column from CTD (conductivity, temperature, depth) casts and from deployment of sea surface drifters. Further information on the survey is available in the post-survey report published as Geoscience Australia Record 2013/38: Nichol, S.L., Howard, F.J.F., Kool, J., Stowar, M., Bouchet, P., Radke, L.,Siwabessy, J., Przeslawski, R., Picard, K., Alvarez de Glasby, B., Colquhoun, J., Letessier, T. &amp; Heyward, A. 2013.

L076 Timor sea / Joseph Bonaparte Gulf seismic "spark array" survey, WA, 1965

The Bureau of Mineral Resources has again'extended its geophysical programme in the search for oil to the continental shelf area of Australia by carrying out a combined gravity, and seismic survey in the Timor Sea/Joseph Bonaparte Gulf area of northwest Australia. The survey investigated the capabilities of the surface marine gravity meter for reconnaissance gravitywork at sea, and the penetration and quality of seismic reflections obtainable using a spark discharge source consisting of an array of electrodes. The possibility of operating the two methods simultaneously was also investigated.

The seismic reflection sections recorded were much better than expected, with good-quality reflections being recorded to 1.6.sec. the gravity meter and seismic'equiPment were operated simultaneously at boat speeds of 8 to 9 miles per hour.

The-seismic results have shown that a large Permian and Mesozoic sedimentary basin exists in the Joseph Bonaparte Gulf and extends to the north and north-west into the Timor Sea. It is an offshore extension of the
Bonaparte Gulf Basin, and contains at least 10,000 feet of post-Permian sediments. .Although the trends of the gravity anomalies agree with the general shape of the basin as defined by the seismic results, a large positive anomaly occupies the central deep part of the basinand does not seem to be related to basement relief.

Autonomous Underwater Vehicle (AUV) for mapping marine biodiversity in coastal and shelf waters: Implications for Marine Management

Autonomous Underwater Vehicles (AUVs) have only recently become available as a tool to investigate the biological and physical composition of the seabed utilizing a suite of image capture and high-resolution geophysical tools. In this study we trialled the application of an AUV, integrating AUV image capture with ship-based high resolution multibeam bathymetry, to map benthic habitats and biodiversity in coastal and offshore waters of SE Tasmania. The AUV successfully surveyed a plethora of marine habitats and organisms, including high-relief kelp-dominated rocky reefs to deep mid-shelf reef and sediments that are otherwise difficult to access. To determine the spatial extent of these habitats within a broader-scale context, the AUV surveys were integrated with larger scale multibeam mapping surveys. The data collected using the AUV significantly improved our understanding of the distribution of benthic habitats and marine organisms in this region, with direct application to the management and conservation of these environments. For example, preliminary results identified the distributional extent of an introduced invasive marine pest, the screw-shell Maoricolpeus roseus, which was recorded adjacent to rocky reefs but is now known to also extend in high abundance across the SE shelf. Integrating the AUV data with the largescale mapping data provided the opportunity to quantify the relationships between the biological and physical variables, and to use thise data to develop predictive models of biodiversity across the region. The effectiveness of the AUV as a pioneering tool for undertaking spatially repeatable surveys makes it a highly versatile technique for future use in surveying remote environments, particularly with respect to surveying and monitoring biodiversity in newly established Commonwealth MPA's. It also has application in the context of climate change, the study of invasive species, impacts of fishing activities and determining the relative uniqueness and/or representativeness of these marine environments.

SSCN SEGMENT 2-B Eastern Recherche Marine Park Bathymetry Acquisition (20240012S)

This dataset is part of a broader survey carried out by EGS onboard the survey vessel RV Bold Explorer (RV BE) during the  SUBCO Subsea Cable Network (SSCN) cable route survey. 

The area is confined to the data within the Eastern Recherche Marine Park. The Survey team and client representative joined the RV Bold Explorer on 17th April 2024 at Fremantle Port,  Australia. Following the embarkation of the survey team, equipment testing and commissioning was carried out. Calibration and verification of the DGPS positioning system and survey gyros onboard RV BE were performed while the vessel was alongside at Fremantle Port, Australia between 17th April and 18th April 2024. 

Prior to departure, tow sensors and hull-mounted sensors were wet tested. All systems were found to be operational. The RV Bold Explorer departed Fremantle Port, Australia and transited to the first site on 19th April 2024. The offshore calibration of shallow water multibeam echosounder (MBES) and USBL were performed on 19th April 2024 while the  calibration of deep water MBES was carried out on 20th April 2024.

The SSCN Segment 2-B survey comprised an investigation of bathymetry, seabed features and shallow geology along the proposed route. A subsequent geotechnical sampling programme was also executed.

This dataset is not to be used for navigational purposes.

Darwin Harbour Habitat Mapping Program: Sediment grain size data

This resource contains sediment grain size data and their summary statistics for the greater Darwin Harbour region. These data were derived from the measurement of sediment grain sizes from seabed samples collected as part of a baseline habitat mapping program for the Darwin Harbour region, including Bynoe Harbour. This project was funded through offset funds provided by INPEX-led Ichthys LNG Project to the Northern Territory Government’s Department of Environment and Natural Resources (NTG-DENR) with co-investment from Geoscience Australia (GA) and the Australian Institute of Marine Science (AIMS). The intent of this program is to improve knowledge of the marine environments in the Darwin and Bynoe Harbour regions by collating and collecting baseline data that enable the creation of thematic habitat maps and information to underpin marine resource management decisions. The sediment samples were collected during multiple surveys undertaken by GA, AIMS and NTG-DENR between 2011 and 2017. A total of 499 samples are reported on from 489 stations with all grain size data published in the Marine Sediments Database (MARS). This dataset is published with the permission of the CEO, Geoscience Australia.

Mesozoic sedimentary and volcaniclastic rocks dredged from the northern Exmouth Plateau and Rowley Terrace, offshore northwest Australia

An extensive program of dredging was undertaken by AGSO in 1990 on the northern Exmouth Plateau and Rowley Terrace margin, mainly to provide geological control for seismic interpretations. Forty-two major Mesozoic lithofacies types were recovered. The rocks indicate that: 1. During the Late Triassic (Norian-Rhaetian), the Rowley Terrace margin was, like the adjacent northern Exmouth Plateau, host to shelf carbonates, including reef and peri-reefal deposits. Volcanics were emplaced along the margin (particularly in the north) during the Late Triassic-Mid Jurassic, probably as a result of the commencement of rifting between Australia and Greater India.  The volcanics were laid down partly or reworked into shallow water , producing hyaloclastites and tuffaceous mudstones with marine microfossils.  By the Early Jurassic, carbonate deposition was restricted to relatively small areas with most of the outer Rowley Terrace being covered by thick, fluvial - paralic siliciclastics with marine interbeds. These deposits continued to be deposited until the early Late Jurassic. They were subjected in the ?Late Jurassic to subaerial exposure under arid conditions resulting in cementation by Fe-oxides. With the early Late Jurassic (Oxfordian- Callovian) breakup and formation of the Argo Abyssal Plain, the margin started to subside and thin, shallow-marine, Late Jurassic-Early Cretaceous sediments were deposited.  These were followed, with continuing margin subsidence, by progressively deeper-water deposits, including Cretaceous and younger hemipclagic-eupelagic claystones, chalks, and marls.  2. Reefs grew in the area of the outer part of the Rowley Terrace during the Late Triassic. The potential therefore exists for Upper Triassic, reefal petroleum reservoirs to be present within the main part of the Rowley Sub-basin to the east, if reefs in that area were not prevented from growing by sand influx from rivers.  Similarly, Lower Jurassic shallow-water platform carbonates, which are present on Triassic horst blocks beneath the central northern part of the Exmouth Plateau, could act as petroleum reservoirs if porosity is preserved.  3. During the Late Triassic and Early Jurassic there is a clear similarity between the facies and associated foraminiferal and ostracod microfaunas of the northern Exmouth Plateau/ Rowley Terrace area and thos e of other southern Tethyan margins, including the Northern Calcareous Alps. This indicates that broadly similar depositional conditions existed along much of Neo-Tethys at that time.

Youngest Permian marine macrofossil fauna from the Bowen and Sydney Basins, eastern Australia

The marine invertebrate macrofauna from the upper part of the Blenheim Subgroup of the Bowen Basin and the Kulnura Marine Tongue of the Sydney Basin is described. The fauna is assigned to 12 genera, one of which - Pseudonucula - is newly recognised, and to 13 species, of which one is new. On the basis of these descriptions and existing published information, three zones are recognised in the Blenheim subgroup, in ascending order, the Martiniopsis magna, the Martiniopsis pelicanensis and the Martiniopsis havilensis zones. An explanation is given of the conclusions of Waterhouse and Jell (1983) about the lower part of the subgroup. From the fauna, particularly the occurrence of Martiniopsis havilensis, it is concluded that a hiatus occurs in the Blenheim Subgroup between the Black Alley Shale and the Peawaddy Formation in the southwestern part of the Bowen Basin, and that the Black Alley Shale is equivalent to the MacMillan Formation in the central part of the basin and the Exmoor Formation in the northeastern part. The upper part of the Blenheim Subgroup (zone of Martiniopsis havilensis) seems to be younger than the Mulbring Shale of the Sydney Basin, and the Kulnura Tongue is not likely to be significantly younger than the Blenheim Subgroup. The faunas described appear to be younger than Kungurian, but are not likely to be younger than the Kazanian. They are rather low in diversity relative to older Permian faunas in the two basins, and this probably reflects the rather restricted marine conditions at the end of the open sea in the two basins.

SUPERSEDED: eReefs GBR4 hydrodynamics v1.85

SUPERSEDED: This dataset has been superseded by GBR4_H2p0 (2010-09 to present) and it was removed from the NCI fx3 project and THREDDS server in April 2024.  An archive copy has been retained by the custodians, and access can be arranged on request.

Results from version 1.85 of the 4 km resolution regional-scale hydrodynamic model of the great Barrier Reef (GBR4). It was forced with BlueLink OceanMAPS data on the open boundaries and Bureau of Meteorology model ACCESS-R for surface atmospheric data. The tide was introduced through 22 constituents derived from the global CSR tide model, and 22 river boundaries incorporated measured stream flow and temperature data from QLD DNRM's gauging stations.

This model version was published for reference in the SIEF report from January 2016, but was later discovered to have been forced with incorrect (multiplicative error) rainfall levels, and the 2015 results contain salinity errors.

This model configuration and associated results dataset may be referred to as "GBR4_H1p85" according to the eReefs simulation naming protocol.

Cenozoic Volcanism of the Capel-Faust Basins, Northern Lord Howe Rise

A recent survey by Geoscience Australia acquired new exploration data and samples in the frontier offshore Lord Hose Rise (LHR) Capel-Faust region. This survey identified a number of volcanic features including cones, flows and sill-related features on the seafloor. Based on analysis of seismic data in the region (s302) and swath bathymetry, there are at least two distinct ages of volcanism exposed on the seafloor; Miocene-Pliocene (approximately 4-7 Ma) cones with a largely unmodified conical shape and Eocene-Oligocene volcanic features. The Eocene-Oligocene edifices can be seen on seismic profiles to extend from Palaeocene-Eocene and Eocene-Oligocene unconformities, in many cases overlying basement highs, through a blanket of marine ooze, to be exposed on the seafloor. Each cone is surrounded by a moat where the currents have eroded sediment. The Gifford Guyot (approximately 18 Ma), part of the Lord Howe Seamount chain was included in the survey area. Volcanic features are common on the seafloor of the Lord Howe Rise and in the neighbouring Tasman Basin, with two identified north-south seamount hotspot chains to the west of the Capel-Faust region that have been active from the Miocene to recent. The ZoNÃ©Co 5 survey also identified a few small conical seamounts on the northern LHR, along a roughly north-northwest trend, dated as Early Miocene.  The younger Capel-Faust seamounts are aligned with these and the age relationships suggest they could be part of a single seamount chain.  The older Eocene-Oligocene cones do not show any preferred alignment within the survey area and are too old to be related to the current hotspot activity identified in the region.

Geology of the Drummond Basin, Queensland

The Upper Devonian to Lower Carboniferous Drummond Basin sequence crops out over an area of approximately 25 000 km2 , mainly west but also east of the Anakie Inlier in east-central Queensland. The Drummond Basin is a structural remnant of a large intermontane depositional basin that developed in the Tasman Geosynclinal zone after the Tabberabberan Orogeny. It received up to 12 000 m of predominantly fluviatile sediments which were transported into the basin by a northerly flowing river system. There may have been some marine incursions. Basement to the basin consists of early Palaeozoic slightly metamorphosed sediments and granite. Sedimentation in the Drummond Basin ceased at the onset of the Kanimblan orogenic event, during which the sequence was folded and uplifted to form a structural high shedding detrital material into the Bowen and Galilee Basins.

Establishing hydrocarbon charge to the Ashmore Platform, Bonaparte Basin, Australia: A natural seep study

To date there is one proven hydrocarbon accumulation on the Ashmore Platform, Bonaparte Basin, Australia, with hydrocarbon charge remaining a key exploration risk. To the south, the neighbouring Browse Basin has proven lateral migration of generated hydrocarbons to the basin bounding highs, as evidenced by seeps located on the Yampi Shelf. This paper describes the findings of a natural seeps study carried out to establish if migrating subsurface hydrocarbons reach the southern flanks of the Ashmore Platform basement high. The integrated study combined remote sensing, geophysical, acoustic, photographic and geochemical techniques and has identified three areas of seepage; one area characteristic of persistent seepage and two areas of interpreted episodic leakage. Geochemical data collected from samples at one of these sites demonstrates the presence of thermogenic liquid hydrocarbons, with isotopic compositions falling within the range of values exhibited by oils sourced by the Lower Cretaceous Echuca Shoals Formation. The identification of active natural seepage along the southern flank of the Ashmore Platform provides evidence that hydrocarbons generated within the Caswell Sub-basin are able to laterally migrate onto the flanks of the Ashmore Platform structural high. As such, these findings reduce charge risk for the Ashmore Platform and regional exploration risks in the northern Browse Basin.

Harvest tonnages by Alginates (Australia) P/L for Macrocystis pyrifera on the east coast of Tasmania 1970-71

As a condition of licence for harvesting Macrocystis pyrifera (Linnaeus) C. Agardh 1820, Alginates (Australia) P/L lodged harvest returns to the Tasmanian Lands Department. The harvest returns consisted of what tonnage was harvested from where, when and the length of trip. While Alginates (Australia) P/L harvested from 1964-1973, harvest data for individual sites is only available for the years 1970-71. Here the data is summed for individual sites for the two years 1970-71.
