Underwater video and still images from the Browse basin (GA340/SOL5754)

Geoscience Australia undertook a marine survey of the Leveque Shelf (survey number SOL5754/GA0340), a sub-basin of the Browse Basin, in May 2013. This survey provides seabed and shallow geological information to support an assessment of the CO2 storage potential of the Browse sedimentary basin. The basin, located on the Northwest Shelf, Western Australia, was previously identified by the Carbon Storage Taskforce (2009) as potentially suitable for CO2 storage. The survey was undertaken under the Australian Government's National CO2 Infrastructure Plan (NCIP) to help identify sites suitable for the long term storage of CO2 within reasonable distances of major sources of CO2 emissions. The principal aim of the Leveque Shelf marine survey was to look for evidence of any past or current gas or fluid seepage at the seabed, and to determine whether these features are related to structures (e.g. faults) in the Leveque Shelf area that may extend to the seabed. The survey also mapped seabed habitats and biota to provide information on communities and biophysical features that may be associated with seepage. This research, combined with deeper geological studies undertaken concurrently, addresses key questions on the potential for containment of CO2 in the basin's proposed CO2 storage unit, i.e. the basal sedimentary section (Late Jurassic and Early Cretaceous), and the regional integrity of the Heywood Formation (the seal unit overlying the main reservoir).

Underwater footage was collected from 49 stations, although quality varies between sites. Video files are located in folder 'SOL5754_TOWVID_VIDEOS'. Each avi file contains several video transects; the associated stations are noted in the file name. Real-time onboard video characterisations using the AIMS- TowedVid classification system are located in folder 'SOL5754_TOWVID_CSVs'.

Still images are located in folder 'SOL5754_TOWVID_STILLS' with sub-folders named according to station number, followed by gear code (CAM=underwater camera system), then the deployment number. For example, 12CAM02 represents a video transect from station 12 that was the 2nd video transect of the survey.

USBL (Ultra-short baseline) text files are located in folder 'SOL5754_USBL_FILES' and provide continuous navigational information on location, time (UTC) and depth of each video transect line.

Notes on proposed diamond drilling at Coronet Hills, Northern Territory

A plane table survey of the lode system at the abandoned Coronet Hills copper mine in the Northern Territory was carried out together with a theodolite survey of the accessible underground workings. There are several sulphide-bearing lodes in a fracture system on the south-western margin of an arched, north-west striking, anticlinorium. The core of the anticlinorium is occupied by chert beds which are conformably overlain by siltstone end greywacke. The lodes are mineralised with copper, lead, and arsenic minerals. Assays of samples from the dumps and underground workings show sporadic values for copper and lead and the ubiquitous presence of arsenic. The deposits appear to be too small to be of much economic interest. However if it is decided to investigate them further six drill holes have been sited to test the extension of three swells in the lodes below the old workings

Epeiric carbonate sedimentation of the Ninmaroo Formation (Upper Cambrian-Lower Ordovician), Georgina Basin

The Ninmaroo Formation (Upper Cambrian-Lower Ordovician) is one of several epeiric carbonate sequences in the Georgina Basin. It comprises ooid, peloid, flat-pebble conglomerate, skeletal and mixed carbonate lithofacies, terrigenous sandstones, and a late diagenetic crystalline dolostone lithofacies. Ninmaroo sedimentation took place in a broad, shallow epicontinental sea under normal marine, increasingly saline, and evaporitic conditions. A barrier complex of ooid, peloid and skeletal sands formed the seaward limit of these environments. Channels through this barrier extended weak tidal effects to the periphery of an extensive, non-tidal complex of semi-emergent shoals in a patchwork pattern, Here, algal and nonskeletal carbonate sedimentation predominated because higher salinities restricted the fauna. Sedimentation was cyclic, probably due to repeated shoaling from storms. Sabkhas developed locally on emergent areas of shoals and landward where the complex was transitional with an emergent pavement. Where emergence was prolonged, microkarst resulted with both carbonate and sulphate dissolution. Lithofacies patterns indicate two regressive depositional sequences. An initial southeastern progradation of the barrier and epeiric environments was over a stable and extensive flat shelf. Subsequent instability increased shelf slope locally, and depositional environments along margins were condensed. With increased tidal circulation, skeletal carbonate production became dominant, producing a second offlap to the southeast.

National Gravity Compilation 2019 includes airborne - CSCBA 0.5VD grid

Gravity data measure small changes in gravity due to changes in the density of rocks beneath the Earth's surface. The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose. 
This National Gravity Compilation 2019 includes airborne - CSCBA 0.5VD grid is derived from the 2019 Australian National Gravity Grids B series. These gravity data were acquired under the project No. 202008. The grid has a cell size of 0.00417 degrees (approximately 435m). This gravity anomaly grid is derived from ground observations stored in the Australian National Gravity Database (ANGD) as at September 2019, supplemented by offshore data sourced from v28.1 of the Global Gravity grid developed using data from the Scripps Institution of Oceanography, the National Oceanic and Atmospheric Administration (NOAA), and National Geospatial-Intelligence Agency (NGA) at Scripps Institution of Oceanography, University of California San Diego. Airborne gravity and gravity gradiometry data were also included to provide better resolution to areas where ground gravity data was not of a suitable quality. Out of the approximately 1.8 million gravity observations, nearly 1.4 million gravity stations in the ANGD together with Airborne Gravity surveys totaling 345,000 line km and 106,000 line km of Airborne Gravity Gradiometry were used to generate this grid. The ground and airborne gravity data used in this grid has been acquired by the Commonwealth, State and Territory Governments, the mining and exploration industry, universities and research organisations from the 1940's to the present day. Station spacing varies from approximately 11 km down to less than 1 km, with major parts of the continent having station spacing between 2.5 and 7 km. Airborne surveys have a line spacing ranging from 0.5 km to 2.5 km. Terrain corrections to gravity were calculated using both offshore bathymetry and onshore topography data. A first vertical derivative was calculated by applying a fast Fourier transform (FFT) process to the complete spherical cap Bouguer anomaly grid of the 2019 Australian National Gravity Grids B series to produce this grid. The grid shows a half vertical derivative of the complete Bouguer anomalies (B series) over Australia and its continental margins.

Halls Creek area airborne radiometric survey, Western Australia 1960

In June and July 1960 a Cessna aircraft of the Bureau of Mineral Resources carried out a low-level airborne radiometric survey over Lower Proterozoic rocks known as the Halls Creek Metamorphics, in the Halls Creek area of Western Australia. This survey was the continuation of a survey carried out in 1959 using an Auster aircraft. An area of 818 square miles was surveyed and 9 anomalies were located. The positions of these anomalies are plotted on the map attached to this report. There appears to be little hope of finding a uranium deposit of economic importance in the Halls Creek Metamorphics.

The geological evolution of the southern Taroom Trough and the overlying Surat Basin

Isopach, structure contour, and palaeo-geological maps illustrate the geological development of the southern Taroom Trough and the lower part of the Surat Basin sequence.
The meridional southern Taroom Trough, 50,000 km2 in area, is a southerly subsurface extension of the outcropping Bowen Basin. It is fault-bounded to the east and plunges northward. The maximum thickness of sedimentary fill increases northward from less than 400 m to 10,000 m, and consists of Lower Permian marine sediments, Upper Permian coal measures, Lower Triassic redbeds, and Middle Triassic stream sediments. The trough's present western margin is depositional, but the faulted eastern margin started to form in the Late Permian in the south and in the Early Triassic in the north; movement ceased in the Early Triassic in the south and in the Late Triassic in the north. Tectonic movements did not recur until Late Jurassic time.

Late Triassic erosion preceded deposition of Surat Basin sediments. These sediments extended over ever wider areas, even the basal sands spreading far beyond the Taroom Trough. The fully-developed Surat Basin is 300,000 km2 in area, and contains up to 2500 m of dominantly continental Jurassic sediments and dominantly marine Lower Cretaceous sediments. Lower Jurassic stream sediments (the main petroleum producers of the basin) are thickest and coarsest above the Taroom Trough, suggesting steady subsidence and compaction of the trough sediments.

By the Late Jurassic this compaction had virtually ceased, and epeirogenic uplift had given the basin its present shape, with the Mimosa Syncline (above the Taroom Trough) and the south-westerly-trending Dirranbandi Syncline (above a basement depression) being major structural features.

Petroleum, which is probably derived from both Permian and Jurassic sources, is most abundant in the Lower Jurassic sandstone on either side of the Mimosa Syncline. Some aspects of the migration and trapping of Permian petroleum are discussed, and it is suggested that the Lower Jurassic Hutton Sandstone in the virtually unexplored Bollon area could be prospective.

Classification of Australian clastic coastal depositional environments based upon a quantitative analysis of wave, tidal and river power

A statistical assessment of wave, tide, and river power was carried out using a database of 721 Australian clastic coastal depositional environments to test whether their geomorphology could be predicted from numerical values. The geomorphic classification of each environment (wave- and tide-dominated deltas, wave- and tide-dominated estuaries, lagoons, strand plains, and tidal flats) was established independently from remotely sensed imagery. To our knowledge, such a systematic numerical analysis has not been previously attempted for any region on earth.

Nutrient dynamics and pelagic primary production in coastal creeks delivering into Keppel Bay

This report describes the investigations into the coastal creek system conducted within the Fitzroy agricultural contaminants project. Before this work started there had been only a limited data acquisition on the water quality parameters in several of the coastal creeks carried out by the Queensland Environmental Protection Agency (EPA). These data are a valuable augmentation to the data collected under Coastal CRC auspices. We briefly outline the consolidated dataset, draw qualitative conclusions from it, and develop a conceptual model reflecting the interacting processes. These analyses are then the starting point for the development of a quantitative characterisation of the role of the coastal creeks in the biogeochemistry of Keppel Bay.

Submerged banks in the Great Barrier Reef, Australia, greatly increase available coral reef habitat

Anthropogenic global ocean warming is predicted to cause bleaching of many near-sea-surface (NSS) coral reefs, placing increased importance on deeper reef habitats to maintain coral reef biodiversity and ecosystem function. However, the location and spatial extent of many deep reef habitats is poorly known. The question arises: how common are deep reef habitats in comparison with NSS reefs? We used a dataset from the Great Barrier Reef (GBR) to show that only about 39% of available seabed on submerged banks is capped by NSS coral reefs (16 110 km2); the other 61% of bank area (25 600 km2) is submerged at a mean depth of around 27 m and represents potential deep reef habitat that is spatially distributed along the GBR continental shelf in the same latitudinal distribution as NSS reefs. Out of 25 600 km2 of submerged bank area, predictive habitat modelling indicates that more than half (around 14 000 km2) is suitable habitat for coral communities.
