National Gravity Compilation 2019 DGIR tilt image

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 DGIR tilt image is produced from the 2019 Australian National Gravity Grids A series. These gravity data were acquired under the project No. 202008. The grid has a cell size of 0.00417 degrees (approximately 435m). The %%MV_DATASETS/SURVEY_NAME% are 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. Out of the approximately 1.8 million gravity observations, nearly 1.4 million gravity stations in the ANGD together with marine data were used to generate this grid. The ground gravity data used in the national 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 for ground observations 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. The DGIR was obtained by subtracting 3 quantities (i.e., the near-field isostatic correction, the far-field isostatic correction, and a first order trend correction) from Complete Bouguer Anomaly data (CBA) of the 2019 Australian National Gravity Grids A series. The image shows a tilt of the de-trended global isostatic residual (DGIR) anomalies (A series) over Australia and its continental margins. A tilt filter was calculated by applying a fast Fourier transform (FFT) process to the DGIR grid of the 2019 Australian National Gravity Grids A series. A tilt filter is a ratio of the vertical derivative to the total horizontal derivative and is used for detection of edges of geological units.

Geoscientific investigations from the Scott Plateau off northwest Australia to the Java Trench

In 1977 the R.V. Valdivia carried out a survey between Scott Plateau and the Java Trench, during which 1700 km of 24-channel seismic data, and 2550 km of bathymetric, gravity and magnetic data, were recorded; and 31 bottom samples were obtained, in water depths ranging from 2000 m to 5800 m. The Scott Plateau trends NNE and is bounded to the west by the Argo Abyssal Plain and to the north by the Roti Basin. The plateau is a foundered continental block, and lies at an average depth of 2000-3000 m. On the plateau the dominant fault direction is NW to WNW, an ancient strike direction on the Australian continent. The western margin probably formed as a series of NE-trending rifts and NW-trending transforms during Late Jurassic breakup. Canyons cut the western margin, and some of these appear to be fault-bounded. One such fault forms the northern margin of a major NW-trending feature, the Wilson Spur. This appears to be a transform fault and perhaps extends across the abyssal plain as far as the eastern end of the Java Trench. Valdivia seismic profiles suggest that, at the trench, it separates thrust-faulted continental crust to the east from oceanic crust to the west. This could explain the eastern termination of the deep part of the trench. The bathymetric depression of the Roti Basin, which lies southeast of the Java Trench, links the trench to the Timor Trough. The Argo Abyssal Plain slopes gently southward, with water depths ranging from 5000 m near the Java Trench to 5730 m in the south. Oceanic basement varies from smooth to hummocky and irregular, and is overlain by about 400 m of acoustically semi-transparent Late Jurassic and Cretaceous sediments, that is in turn unconformably overlain by 200 m of layered Tertiary sediment. Bottom samples taken by R.V. Valdivia from the outer Scott Plateau have provided new information about seismic sequences. They show that Callovian breakup was preceded by a period of basic volcanism and shallow marine sedimentation, that restricted shallow marine conditions followed in the Late Jurassic, and that bathyal carbonate sedimentation prevailed by the Late Cretaceous (Campanian). Quaternary marls cored on the northern Scott Plateau straddled the Pleistocene-Holocene boundary, and siliceous oozes cored on the southern slope of the Java Trench contain nannofossils which, below a few decimetres, are older than late Pleistocene. The Java Trench cores indicate that the calcite compensation depth was apparently between 5420 and 5700 m in the early or middle Pleistocene, and is above 4950 m now. The Scott Plateau cores indicate that the present calcite compensation depth in the region lies below 3290 m. On the Scott Plateau Holocene sedimentation rates are about 5 cm/I000 years, but in the Java Trench they are much lower. Manganese oxide crusts and nodules were recovered from the Scott Plateau, but their content of valuable metals was low.

Surface and Sub-surface Geology and the Role of Basement Structure in the Capel-Faust basins, Offshore Eastern Australia

The Capel and Faust basins are part of the northern Lord Howe Rise, offshore eastern Australia. These frontier basins formed during the initial phases of extension leading to the Cretaceous break up of the east Gondwana margin. The basins subsided to their present depths of 1300-2500m in the early Cenozoic. Geoscience Australia is investigating the geology and marine environment of this frontier area as part of the Australian Government's New Oil (2003-2007) and Energy Security (2007-2011) programs. High resolution 2D seismic, gravity, magnetic and multibeam bathymetry data were acquired in 2006-2007 and synthesised to derive 2D and 3D geological information and knowledge of these basins and underlying basement. A clear relationship between surface and sub surface geology was observed. This has contributed to an improved understanding of basin structure, large scale basin architecture, tectonic reactivation along the basin margins, and potential fluid migration pathways. An analysis of seafloor features will also contribute to future marine bioregional
planning in the study area.

Molecular Hydrogen from Organic Sources in Geological Systems

We have recently shown that molecular hydrogen generation from organic matter occurs at high maturity levels (vitrinite reflectance 3–5%) in Lower Cretaceous shales of the Songliao Basin. To evaluate and extend these implications to a wider range of source rock types and organofacies, we report on two Paleozoic maturity suites from Australia, namely the Permian Patchawarra Formation (fluviodeltaic; Type-III; Cooper Basin) and the middle Cambrian Arthur Creek Formation (marine; Type-II; Georgina Basin), and additional mature marine source rocks from Europe and the USA.

It can be inferred from high resolution mass spectrometry that rapid growth of aromatic ring systems is the major pathway for the formation of thermogenic molecular hydrogen from all organic matter types. Extensive open system pyrolysis experiments indicate that the main generation pulse occurs in the vitrinite reflectance range 3.5–5.0%. Kinetic parameters were constructed by subtracting the hydrogen associated with hydrocarbon formation from total hydrogen in the open-system experiments via adjustment factors defined by the relative yields of CH4 and H2. A cumulative H2 potential of 20 mg/g TOC is found with maximum rates of generation that are sufficient for feeding the deep biosphere. Back of the envelope calculations indicate ∼3.5E+10 tonnes of in-place accessible H2 globally, which is an order of magnitude lower than in-place shale gas resource estimates. Regionally, inferred here for the Patchawarra Formation in the Nappamerri Trough (Cooper Basin), yields per unit rock volume resemble those of economic shale gas in the Barnett Shale, Fort Worth Basin, USA.

Organic particles are, at the SEM-scale (&gt;30 nm), barren of secondary porosity in the case of terrigenous samples at all maturity stages, but show sponge-like porosity in the investigated marine source rocks exhibiting vitrinite reflectance &gt;∼2.0%. Presence of such meso- and macropores is crucial for H2 storage in marine shales, as microporosity (&lt;2 nm) yielding sorptive storage space for H2, is usually much higher in mature terrigenous kerogens.

Dynamics and connectivity of the Bonney Coast Upwelling on a daily scale using the Himawari-8 dataset

The Bonney Coast Upwelling (BCU) is a key ecological feature in the Australian marine regime; it helps contribute to the largest fin fish based fishery in Australian waters and is a feeding ground for the endangered blue whales. The BCU is a seasonal wind driven feature that operates intermittently (on the time scale of between a few days to a couple of weeks) throughout the Austral summer. Since its discovery in the late seventies, the region has been investigated using a range of physical oceanographic techniques, from shipboard sampling to modelling and remote sensing. The latter of which has, until recently, been limited by the temporal frequency of the MODIS and AVHRR passes over the Australasian region, (twice a day) making the data susceptible to cloud contamination. The geostationary Himawari-8 satellite, which became operational in late 2015, is an ideal platform to provide adequate temporal resolution to overcome the cloud contamination problem. This study generates sea surface temperature (SST) daily composites from hourly Himawari-8 images, during the period from November 2016 - March 2017. A topographical position index method is used to isolate the upwelling signatures in the Bonney Coast region from these daily images. With the BCU mapped on a daily basis, we are able to, for the first time, quantitatively investigate the spatial and temporal development of the BCU from onset to termination during an entire upwelling season. In addition, the study will also be able to investigate the connectivity between the BCU and other local upwelling features off Kangaroo Island and the Eyre Peninsula.

A Survey of the Macrocystis pyrifera (L.) C. Agardh Stocks on the East Coast of Tasmania, 1988.

The results of this survey are based primarily on the first hand experience of Craig Sanderson who was doing his masters thesis at the time on aspects of the biology of Macrocystis pyrifera (Linnaeus) C. Agardh 1820. In need of significant beds of M. pyrifera for research much of the east coast was searched by boat. Significant stands (&gt;1/2 acre) were found at Darlington, Southerly Bottom (East North Bay), Fortesque Bay and George III Rock, (near Actaeon Island). The status of the few areas not visited was determined from anecdotal reports.

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.

A Survey of the Macrocystis pyrifera (L.) C. Agardh Stocks on the East Coast of Tasmania, 1999.

A survey was conducted for Macrocystis pyrifera (Linnaeus) C. Agardh 1820 from Eddystone Point to South East Cape

The survey was conducted from light aeroplane. Areas of Macrocystis pyrifera beds were marked on 1:100,000 topographical land tenure maps using landmarks as references. A Trimble GPS unit was used to track position in the aeroplane. As boundaries of the beds were flown over, these were marked on the GPS. When plotted up, these information assisted in determining Macrocystis bed boundaries where these were not close to the coast.

Stock assessment of Macrocystis pyrifera beds at varying locations on Tasmania's south and east coasts 1950-1953, published 1954.

Surveys were conducted as part of an assessment of the Macrocystis pyrifera (Linnaeus) C. Agardh 1820 beds on the east coast of Tasmania by the Commonwealth Scientific and Industry Research Organization (CSIRO) Division of Fisheries seaweed program in the early 1950's. Surveys were conducted because of interest in the Macrocystis beds as a source of alginates. Surveys were done between 1950 and mid 1953. The paper was published in 1954.

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.

A Survey of the Macrocystis pyrifera (L.) C. Agardh Stocks on the East Coast of Tasmania, 1986.

A survey of the east Tasmanian coastline from Musselroe Bay to South East Cape revealed a total of 10 km2 of Macrocystis pyrifera (Linnaeus) C. Agardh 1820 kelp forest. Average harvestable quantities based on Alginates (Australia) Company records (1965-72) show that cropping can expect to yield 5 ton/acre or 1.23 kg/m2. This realizes a total of 12,300 tonne available on the East Coast of Tasmania in 1986. Review of past records show fluctuations in total amounts harvested, due possibly to factors such as high oceanic water temperatures with subsequent low nutrient concentrations and storm damage.
The survey was conducted from a light aeroplane. Areas of Macrocystis pyrifera beds were marked on 1:100,000 topographical land tenure maps using landmarks as references. Digitising of bed outlines on maps was done using Mapinfo.
Weight of Macrocystis per unit area is also estimated from quadrats harvested at a number of sites along the coast.

RV Investigator Voyage IN2022_V09 eDNA Data

This record describes the environmental DNA (eDNA) data collected on Investigator voyage IN2022_V09, titled "Valuing Australia’s new Gascoyne Marine Park." The voyage took place between November 19, 2022 and December 19, 2022 (AEST), departing from Fremantle and returning to Fremantle.

The goal of this study was to leverage existing survey technology to design and test an eDNA sampler that captures an integrated eDNA sample over the length of a deep-water transect. Three different methods were compared for processing the captured eDNA from the sampler: filtering OCD water, extracting eDNA from sponge pieces, and filtering sponge rinse water. Using fish as our example organism, the identities of fishes from eDNA detections were also compared with bottom trawl survey data collected during the same survey, and the known regional species pool, to confirm the eDNA identifications were plausible.
