Grab photos from CEAMARC voyage, 2007-2008

Seabed samples were collected from 52 sites across the George V continental shelf and slope during voyage 3 on the Aurora Australis, December 2007 - January 2008. Most samples were collected with a box corer (BC), though more gravelly sediments required a Smith-McIntyre (GRSM) or Van-Veen grab (GRVV) as indicated by the station name. Sediments were photographed on deck immediately following collection. This dataset contains these photos, labelled according to the station number, sample type and  sample number at that site.

Towards spatially distributed quantitative assessment of tsunami inundation models

In this paper a new benchmark for tsunami model validation is pro-
posed. The benchmark is based upon the 2004 Indian Ocean tsunami,
which provides a uniquely large amount of observational data for model
comparison. Unlike the small number of existing benchmarks, the pro-
posed test validates all three stages of tsunami evolution - generation,
propagation and inundation. Specifically we use geodetic measurements
of the Sumatra{Andaman earthquake to validate the tsunami source, al-
timetry data from the jason satellite to test open ocean propagation,
eye-witness accounts to assess near shore propagation and a detailed inundation survey of Patong Bay, Thailand to compare model and observed inundation. Furthermore we utilise this benchmark to further validate the hydrodynamic modelling tool anuga which is used to simulate the tsunami inundation. Important buildings and other structures were incorporated into the underlying computational mesh and shown to have a large inuence of inundation extent. Sensitivity analysis also showed that the model predictions are comparatively insensitive to large changes in friction and small perturbations in wave weight at the 100 m depth contour.

Basins of the Great Australian Bight : Geology and Petroleum Potential

In 1986, the Bureau of Mineral Resources (BMR) set out to rekindle
exploration interest in the Great Australian Bight and to answer some of
the perceived geological problems of the area, by conducting a regional
framework multichannel seismic survey with follow-up sampling and
heatflow work using the RfV Rig Seismic. At about the same time, the
South Australian Department of Mines and Energy (SADME) commenced a
project that involved re-interpreting existing company seismic data in
the Duntroon Basin and other areas in South Australian waters, with a
view to promoting a new round of exploration. In 1987, it was decided
that BMR and SADME should pursue a joint study, with the aim of covering
as much of the Great Australian Bight as possible. Areas of
responsibility were allocated such that SADME concentrated on the
shallow water Duntroon and Denman Basins, while BMR studied the deeper
water Great Australian Bight Basin (including the Eyre Sub-basin), the
Polda Trough, and the Bremer Basin further west. This folio is the
principal product of the joint study.
Since this report is the combined effort of two widely separated
organisations, it is inevitable that there will be some differences in
interpretation and style of presentation. While the editors (Stagg,
Cockshell, and Hill) have endeavoured to produce a final document that
is devoid of internal inconsistencies, no doubt some will still remain.

Australia's Maritime Zones Edition 5

This map supersedes the Australia's Maritime Zones/Boundaries Map Edition 4, published in November 2013. Catalogue Number/GeoCat 69822.  

This map has been derived from Geoscience Australia's Australian Maritime Boundaries (AMB) 2014 data which is a digital representation of Australia's territorial sea baseline and the maritime limits and boundaries as established under the Sea and Submerged Lands Act 1973. 

On the 9 April 2008 the Commission on the Limits of the Continental Shelf confirmed Australia's continental shelf limits. This edition shows those limits together with those areas yet to be resolved and the area off the Australian Antarctic Territory that Australia requested the commission not consider for the time being.

The map describes the different maritime zones, explains how Australia defines and updates its maritime boundaries, and lists the different maritime boundary arrangements with Indonesia, Papua New Guinea, Solomon Islands, France (New Calendonia and Kerguelen) and New Zealand.  It shows the extent of Australia's maritime boundaries, stretching from Heard and McDonald Islands in the west to Norfolk Island in the east, and from the Torres Strait and Arafura Sea in the north to the Australian Antarctic Territory in the south.

Vulcan Sub-Basin, Timor Sea Survey 97 : High Resolution Seismic Reflection Profiling and Direct Hydrocarbon Detection (Vulcan I) : Post-cruise Report : Project 121.19

The objectives of Project 121.19 were: To understand the deep crustal architecture, the structural reactivation processes and the mechanisms of hydrocarbon generation, migration and entrapment within the Vulcan Sub-Basin, Timor Sea. To achieve the aims of the project, two surveys (Vulcan I &amp; II) were conducted between October and December 1990. This report summarises the results of the Vulcan Sub-Basin I Survey (Survey 97), which focussed on the high resolution seismic and geochemical component of Project 121.19 (i.e. the structural reactivation, hydrocarbon generation and migration theme).  The Timor Sea program achieved most of its objectives. The seismic data should, when processed, allow a much better understanding of the nature of the fault reactivation processes in the area. In addition, strike lines run along the Londonderry High show that near-vertical faults appear to correspond with the position of transfer faults which have been inferred from our interpretation of BMR's Timor Sea aeromagnetic data. The geochemical program identified a number of significant hydrocarbon anomalies in the area. The anomalies fell predominantly into two groups. One group was located over, and to the north-east to south-east of the Skua Field, while the other group was associated with transfer faulting, and a major aeromagnetic high, on the edge of the Vulcan Sub-Basin, south-east of Montara 1.

The Mesozoic Carpentaria Basin and the Cainozoic Karumba Basin, north Queensland

The Jurassic - Cretaceous Carpentaria Basin of northern Queensland and eastern Northern Territory and adjacent marine areas approximates to the Gulf of Carpentaria and its eastern and southern hinterland (Fig. 1). The Cainozoic Karumba Basin overlies the Carpentaria Basin; its boundaries are the watersheds of the Gulf of Carpentaria drainage basin (Fig. 18). This Bulletin and its maps are a summary and a synthesis of geological information collected during field surveys which began in 1969 by combined parties of the Bureau of Mineral Resources (BMR) and the Geological Survey of Queensland (GSQ), and of all other geological investigations in the area. It also includes a review of geophysical surveys of both Basins. Local detail can be found in the Progress Reports. Explanatory Notes, and papers listed in Tables 1 and 2. Geological mapping was based on the use of aerial photographs of the RC9 Series (1:80 000) except in the northeast of Cape York Peninsula where the older K17 series (1:48 000) and other aerial photographs were used to obtain complete coverage. Landsat imagery was used to supplement aerial photographs. Mapping was supplemented by shallow stratigraphic drilling and augering (see Table 1) and by wire-line logging of water and other bores under contract (Down Under Well Services Pty Ltd) and by personnel from Geophysical Branch, BMR. Smart &amp; others (1974) list details of holes logged; copies of logs are held by BMR, GSQ. and the Irrigation and Water Supply Commission (IWSC), Brisbane.

Vlaming Sub-basin and Mentelle Basin: Environmental Summary

This report is one of a series of environmental summaries of frontier basins, which are scheduled for acreage release during the timeframe of the 'Energy Security Initiative' (2007-2011). The aim of these reports is to synthesise the available environmental information to adequately equip the exploration industry to anticipate as many as possible of the environment-related issues that may impact on exploration and potential future production activities.

The environmental information for the Vlaming Sub-basin and Mentelle Basin has been compiled and presented in a manner consistent with the Geographic Information System (GIS) provided with this report. The GIS includes the results of an analysis to obtain representative seascapes. Seascapes are the principal environmental output and in recent years assisted Department of Environment, Water, Heritage and the Arts with the design and implementation of a National Representative System of Marine Protected Areas for Australia (Section 1.1). The following section summarises the geological history of the Vlaming Sub-basin and Mentelle Basin and provides a tectonic and depositional context for the geophysical data and geomorphology of the sub-basin, which are discussed in Sections 3 and 4, respectively. The surface sediment properties are described in Section 5. These sections provide all of the information necessary to characterise benthic habitats. Section 6 discusses the oceanographic processes operating in the sub-basin, which influence both the benthic and pelagic ecology described in Section 7. Section 8 synthesises the information contained in the first seven sections into a seascape map of the Vlaming Sub-basin and Mentelle Basin.

Review of Ten Key Ecological Features (KEFs) in the Northwest Marine Region

The Department of the Environment, Water, Heritage and the Arts (DEWHA) has identified as key ecological features (KEFs) numerous geomorphic features or regionally important species or habitats in the northwest marine region. This process supports the department's establishment of the development of Marine Bioregional Plans and a National Representative System of Marine Protected Areas (NRSMPA). A total of ten KEFs are included in this study of which seven lie in the deep-sea where information on biodiversity and ecosystems is scarce. The ten KEFs are: Wallaby Saddle, Cuvier Abyssal Plain, Cape Range Canyons, Exmouth Plateau, Argo Abyssal Plain, Bowers and Oates Canyons, Scott Plateau, Scott Reef, the Holocene Coastline, and Glomar Shoals. Geoscience Australia was engaged to investigate habitat heterogeneity of these KEFs utilising its existing expertise in habitat mapping and surrogacy.

Effects of a major earthquake near Bougainville, 20 July 1975

On 20 July 1975 a major earthquake (MS7.9) shook the northern islands of the Solomon Islands chain. Damage amounting to at least $300,000 (Australian) occurred in the southern Bougainville/Shortland Islands region, where earthquake intensities were estimated to be MMVII-VIII. A tsunami with maximum amplitude of about two metres followed the earthquake and caused further damage. The earthquake caused landsliding, liquefaction, subsidence, slumping of roads and wharfs, and damage to villages, small government and mission buildings, and to the mining installations at Panguna. Aftershock epicentres were in a roughly elliptical area of 12 500 square kilometres off the southwestern coast of Bougainville. Focal depths were in the range 30-70 km. A fault-plane solution and the pattern of aftershocks indicate that the principal earthquake was associated with underthrusting of the Solomon Sea crust beneath Bougainville, in a northeasterly direction and with a dip of about 37Â°. The faulting associated with the 20 July 1975 earthquake appears to be the extension of faulting associated with a 1974 earthquake series. An aseismic zone, centred at 6Â°S, 154Â°E, exists immediately northwest of the 1975 earthquake fault zone, between zones where major earthquakes have occurred since 1970. It is considered to be a likely place for a major earthquake in future.

Enhancing Marine Spatial Planning through Integrated Seabed Mapping and Science Communication

Pre-competitive geoscience information, including bathymetry compilations, seabed geomorphology and sediment stability maps and other spatial information is essential to support planning and investment decisions. Integrated, multidisciplinary datasets enhance our understanding of Australia's seabed and have wide-ranging applications across multiple ocean sectors. Bathymetric and geoscience maps are used to design surveys, identify areas suitable for offshore infrastructure, and provide important regional context for environmental impact assessments, thereby reducing investment risk and supporting evidence-based decisions consistent with government policies and regulations.&nbsp;

Geoscience Australia’s integration and digital delivery of marine data provides valuable insights into the distribution and evolution of seabed features and their associated characteristics, processes and regulatory designations. Our Australian Marine Spatial Information System (AMSIS) provides a web-based interactive mapping and decision support system that improves access to integrated government and non-government spatial layers, tools, visualizations, and data for the management of Australia’s marine jurisdiction. This robust scientific information ecosystem drives the translation of data into information and knowledge to support decision-makers

Cyclone-induced Net Sediment Transport Pathway on the Continental Shelf of Tropical Australia Inferred from Reef Talus Deposits

Tropical cyclones affect storm-dominated sediment transport processes that characterise Holocene shelf deposits in many shelf environments. In this paper, we describe the geomorphology of reef talus deposits found in the Gulf of Carpentaria and Arafura Sea, Australia,that we attribute to tropical cyclones. The orientation of these deposits is also indicative of a consistent, along-coast transport pathway.

Miocene volcanic seamounts on northern Lord Howe Rise: lithology, age, ferromanganese crusts, and origin

Multibeam sonar swath-mapping has revealed small submarine volcanic cones on the northeastern Lord Howe Rise (LHR), a submerged ribbon continent. Two such cones, aligned NNW and 120 km apart, were dredged at 23-24Degrees S. Water depth is about 1150 m nearby: the southern cone rises to 750 m and the northern to 900 m. Volcanic rocks dredged from the cones are predominantly highly altered hyaloclastites with minor basalt. The clasts are mostly intensely altered vesicular brownish glass with lesser basalt, in zeolitic, clayey, micritic or ferruginous cement. Lavas and hyaloclastites contain altered phenocrysts of olivine and plagioclase, and fresh clinopyroxene. The latter have compositions between acmite and Ti-augite, and match well clinopyroxene phenocrysts in undersaturated intraplate basanitic mafic lavas. 

Interbedded micrites in the volcaniclastics represent calcareous ooze that was deposited with (or later than) the volcanic pile. Foraminifera indicate that the oldest micrite is late Early Miocene (~16 Ma), and that the original ooze was deposited in cool water. Late Miocene to Pliocene micrites, presumed to be later infillings, all contain warm water forms. This evidence strongly suggests that both cones formed in pelagic depths in the Early Miocene. Ferromanganese crusts from the two cones are up to 7 cm thick and similar physically, but different chemically. The average growth rate is 3 mm/m.y.. Copper, nickel and cobalt content are relatively high in the north, but copper does not exceed 0.08 wt %, nickel 0.65% and cobalt 0.25%. The Mn:Fe ratio is high in the south (average 13.7) suggesting strong hydrothermal influence.

Such small volcanic cones related to intraplate hotspot-type magmatism may occur in extensive fields like those off southern Tasmania. On Lord Howe Rise, the known small volcanic cones coincide with broad gravity highs in areas of shallow continental basement. The highs probably represent Neogene plume-related magmatism. The thick continental crust may dissipate and spread the magma widely, whereas plumes may penetrate thin oceanic crust more readily and build larger edifices. The correspondence of the ages derived from micropalaeontology and from extrapolating from nearby dated hotspot traces support such a genesis. Accordingly, gravity highs in the right setting may help predict fields of small volcanic seamounts.
