National Gravity Compilation 2019 includes airborne (CSCBA 1VD)

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 1VD) is the first vertical derivative of the complete spherical cap Bouguer anomaly grid for the 2019 Australian National Gravity Grids B series. This gravity survey was acquired under the project No. 202008. The grid has a cell size of 0.00417 degrees (approximately 435m). A Fast Fourier Transform (FFT) process was applied to the original grid to calculate the first vertical derivative grid.

Apparent conflicting Roadian–Wordian (middle Permian) CA-IDTIMS and palynology ages from the Canning Basin, Western Australia

U–Pb dating of zircons from thin middle Permian tuffs in the Canning Basin of Western Australia by chemical abrasion-isotope dilution thermal ionisation mass spectrometry reveals a conflict with the established spore-pollen zonation. Normally, the first appearance datum of Dulhuntyispora granulata across the continent lies stratigraphically above assemblages assigned to the Microbaculispora villosa Zone. However, the youngest tuffs within non-marine facies from the M. villosa Zone in Pittston SD-1, drilled in the southwest of the Canning Basin, yielded an age of 267.04 ± 0.14 Ma, which is 1.7 million years younger than tuffs associated with the D. granulata Zone in marginal-marine facies from core holes 350–400 km to the northeast. The apparent conflict in ages is possibly due to the non-marine depositional environment having wielded a strong local influence on the palynoflora along the edge of this basin. Although the present information indicates an age 2.5 million years younger than the 266.6 Ma age previously suggested for the top of the M. villosa Zone, revisions to the ages of Roadian–Wordian spore-pollen zones are not considered justifiable without further supporting evidence. Furthermore, considerable care is needed when comparing palynological assemblages from significantly differing facies. Two basaltic sills (43.5 m and 20 m thick) immediately below the tuffaceous beds in Pittston SD-1 are coincidental, as Ar–Ar dating indicates a Late Triassic age for the intrusions.

Summary Of Data And Results Gippsland Basin, Victoria Wellington Park No 1 Well Of Woodside (Lakes Entrance) Oil Company NL

Wellington Park No. 1 Well was located in the Gippsland Basin, Victoria, on the south-eastern shore of Lake Wellington. about 25 1/2 miles south-west of Bairnsdale. The well was drilled by Oil Drilling and Exploration Limited for Woodside (Lakes Entrance) Oil Company No Liability. to a total depth of 12,011 feet. Drilling commenced on 6th December. 1961 and was completed on 3rd April. 1962. A comprehensive programme of drilling engineering, mud logging, coring. cuttings examination. and electric logging was conducted, but no significant shows of oil or gas were encountered.

The well penetrated Quaternary sediments from surface to 120 feet. Tertiary sediments from 120 to 3370 feet. and Mesozoic non-marine sediments from 3370 feet. and bottomed in the Lower Cretaceous - (?)Jurassic Strzelecki Group at 12,011 feet. Palaeozoic rocks. one of the main objectives. were not reached because of the extreme thickness of the Mesozoic section.

Five open hole formation tests over various intervals between 7348 and 9930 feet were undertaken, but only three were successful. These tests produced mud filtrate, mud, and formation water. The well was plugged and abandoned as a dry hole on 7th April, 1962.

The stratigraphic drilling operation at Wellington Park No. 1 was subsidized under the Petroleum Search Subsidy Act 1959. from 3391 feet to total depth.

The Kenn Plateau Off Northeast Australia: an Important Continental Fragment in the Southwest Pacific Jigsaw

The submarine Kenn Plateau has an area of about 140,000 kmÂ² and lies 500 km east of central Queensland beyond the Marion Plateau. It is one of several thinned continental fragments lying east of Australia that were once part of Australia, and it originally fitted south of the Marion Plateau as far south as Brisbane. It is cut into smaller blocks by east and northeast trending faults, with thinly sedimented basement highs separated by basins containing several kilometres of sediment. In the Cretaceous, it was probably underlain by rocks of the New England Fold Belt on which were stacked Late Triassic to Late Cretaceous basins. Late Cretaceous stretching and breakup was followed by Paleocene drifting, and the Kenn Plateau moved away to the northeast, rotating 45 degrees clockwise and leaving the Tasman Basin oceanic basalts behind. During these processes, siliciclastic sediments poured into the basins from the mainland and from locally eroding highs, but this sequence was terminated by a regional Late Paleocene to Early Eocene unconformity. Rift volcanics are common on the northern plateau. Radiolarian chalks were widely deposited until biosiliceous sedimentation ended with the regional Late Eocene to Early Oligocene unconformity, and warming surface waters led to younger chalk deposition. Some seismic profiles show the Middle to Late Eocene compression so well exemplified in the New Caledonian obduction to the east. Hotspots formed two volcanic chains as the plateau moved northward: the Oligocene Tasmantid chain in the west, and the Neogene Lord Howe chain in the east. As the volcanoes subsided they were fringed by reefs, some of which have persisted until the present day, whereas other reefs have not kept up with subsidence so guyots formed. The plateau has subsided 2000 m or more since breakup and is now subject solely to pelagic carbonate sedimentation.

Novel method to concurrently sample the planktobenthos and benthos

The planktobenthos is an important area with unique environmental conditions and represents the immediate link between the benthos and the water column. Despite its close links with the seafloor, the planktobenthos has never been deliberately sampled concurrently with the benthos. We have developed a new method for planktobenthic sampling which allows concurrent collection of benthic and suprabenthic specimens. The Mounted Assembly for Planktobenthic Sampling (MAPS) uses a novel tri-layered net with a seafloor-triggered opening and closing mechanism attached to an epibenthic sled. The MAPS was deployed on the Carnarvon Shelf in Western Australia and was successful at separately sampling both benthic and planktobenthic fauna. A wide variety of epibenthic and infaunal animals were collected from the sled while planktobenthic animals such as mysids were identified from all three nets. The tri-layered net was particularly effective at collecting a broad range of planktobenthic organisms, including smaller fragile larvae and adults which may have otherwise been destroyed during collection in a single net. The number of species in planktobenthic and benthic samples was correlated, although the strength and significance of this relationship varied among taxonomic groups. Importantly, the MAPS can be modified for use on a wide variety of benthic sleds to target a range of organisms. The concurrent collection of planktobenthic and benthic biota will contribute to a range of research areas, including larval ecology, nutrient cycling, biogeography and surrogacy research.

Roebuck and Offshore Canning Basin Biozonation and Stratigraphy Chart No.14

Biostratigraphy is the branch of stratigraphy that uses fossils to establish relative ages of rock and correlate successions of sedimentary rocks within and between depositional basins. A biozone is an interval of geologic strata characterised by certain fossil taxa. Such intervals are often defined by the first appearances (range bases), apparent extinctions (range tops/last appearances), or abundances of fossil index species. These key index species should be relatively abundant, short-lived taxa that are easy to recognise and as geographically widespread as possible. Widely used fossil groups include brachiopods, conodonts, dinoflagellate cysts, foraminifera, graptolites, nannofossil, spores and pollen and trilobites. Zonal schemes based on several different fossil groups can be used in parallel, and the zones can be calibrated to the absolute geological timescale using tie points to rocks which have been radio-isotopically dated.

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.

This research is supported by the National Environmental Science Program (NESP) Marine Biodiversity Hub through Project D1.

Macrobenthic Activity and its Effects on Biogeochemical Reactions and Fluxes

Ocean margins are the transitional zones between the oceans and continents. They represent dynamic systems in which numerous processes shape the environment and result in impacting the utilization and hazard potentials for humans. These processes are influenced by a variety of steering mechanisms, from mountain building and climate on the land to tectonics and sea-level fluctuations in ocean margins. This book examines various aspects of regulation for the long-term development of ocean margins, of the impact of fluids and of the dynamics of benthic life at and below the seafloor in ocean margin systems.
