Ordovician, Silurian, and Devonian bryozoa of Australia

The original aim of this study was to investigate some of the early Palaeozoic Bryozoa of Australia so as to study the development of skeletal structures in the zoaria and the significance of distribution of species in the different stratigraphic successions. It was found that areas with abundant bryozoan faunas were not readily located; in many areas such as the Yass-Taemas and Tamworth districts, New South Wales, where Silurian and Devonian marine faunas are abundant, Bryozoa were poorly represented. Thus the work became an investigation of areas where Bryozoa were located. The Middle and Upper Ordovician exposures in parts of central-western New South Wales and the Middle and Upper Devonian sequence of the Fitzroy Basin (collected by the field parties of the Bureau of Mineral Resources) contained abundant bryozoan faunas at certain horizons; but they were not distributed continuously through any considerable thickness of succession. Many samples from which Bryozoa are described in the text are isolated occurrences from which two, sometimes three, species have been collected.

The Morphology of Barchan-shaped Sand Banks from Western Torres Strait, Northern Australia

Large barchan shaped sand deposits have been observed in the north west of Torres Strait. These deposits share characteristics of both subaerial barchan dunes and subaqueous sand banks. Satellite imagery shows that the deposits migrate in the direction indicated by their horns (10-15 m west per year), and that sediment is shed from their horns, features that are characteristic of subaerial barchan dunes. However the orientation of sandwaves superimposed upon the sand banks indicate the presence of mutually evasive channels and circulation of sediment around the sand bank, a characteristic of subaqueous sand banks. The presence of mutually evasive channels is the criteria used to categorise the deposits as sand banks. 

Barchan forms are known to exist in regions with limited sediment supply and unidirectional current or wind regimes. In the Torres Strait both these criteria are met. Previous work has demonstrated the presence of a net westward current through the Torres Strait that is driven by the southeast trade winds. The relatively high displacement of the wind driven currents during the trade wind season relative to the monsoon appears to provide the necessary "unidirectional" regime to form barchans. The low, and typically eastwards, displacement of the residual monsoon season current appears to have a negligible affect on the barchan form.

The Creation of High Resolution Bathymetry Grids for the Lord Howe Island Region

Detailed seabed bathymetric data are needed to better understand our marine environment because models of seabed morphology derived from these data provide useful insights into physical processes that act on the seabed and the location of different types of seabed habitats. Lord Howe Island lies approximately 450km off the northern coast of New South Wales. It is a volcanic island with a fringing coral reef on its western shore, and a shallow (20 - 120 m) shelf surrounds the island. Bathymetry data are required in this area to help identify major seabed processes and habitats, especially relict reef structures, and to measure how well physical seabed properties act as surrogates of patterns of biodiversity on this mid-ocean carbonate shelf. The data are also required to enable modelling of tsunami as they interact with the shelf around the island and the coast. 

This report describes the methodology employed in creating detailed bathymetry data grids of the Lord Howe Island region. It covers data collection, quality control and gridding. Descriptions are provided of each dataset employed, the methods used to integrate the different datasets and the attributes of the new bathymetry models.

Four new bathymetry grids are presented, including grids that integrate bathymetry with the island's topography.

Davis Coastal Seabed Mapping Survey, Antarctica (GA-4301 / AAS2201 / HI468) - High Resolution Backscatter Grids

The Davis Coastal Seabed Mapping Survey, Antarctica (GA-4301 / AAS2201 / HI468) was acquired by the Australian Antarctic Division workboat Howard Burton during February-March 2010 as a component of Australian Antarctic Science (AAS) Project 2201 - Natural Variability and Human Induced Change on Antarctic Nearshore Marine Benthic Communities.
The survey was undertaken as a collaboration between Geoscience Australia, the Australian Antarctic Division and the Australian Hydrographic Service (Royal Australian Navy). The objectives were to provide multibeam bathymetry and backscatter of the coastal region of the Vestfold Hills around Davis Station, Antarctica, to aid the understanding of sea bed character, benthic habitats, provide a basis for hydrodynamic modeling of water movement around Davis, and to update and extend the navigational charts of the region.

Palynology of Mesozoic dredge samples from the North West Shelf

Palynological examination was carried out on 34 sedimentary rock samples dredged from the offshore Rowley Terrace (Canning Basin), Scott and Exmouth Plateaux, and northern Carnarvon Terrace (Carnarvon Basin). The samples represent (1) an Upper Triassic (Rhaetian) to Middle Jurassic (Bathonian) sequence of paludal to restricted-marine character on the Rowley Terrace, with a sample gap in the Early Jurassic; (2) an Upper Jurassic (Oxfordian- Kimmeridgian) sequence of shallow-marine characler on the Rowley Terrace; and (3) a Lower Cretaceous (Valanginian-Aptian) sequence of open-marine character on the Carnarvon Terrace.  Most samples yielded rich to very rich and varied dinocyst and spore-pollen floras, and were dated with reasonable confidence. Long-term changes are detected in environments of deposition from different areas, and some of the changes are suggested to be of eustatic origin.

Marine fossils from the Upper Jurassic and the Lower Cretaceous of Dampier Peninsula, Western Australia

In several publications which have appeared during the last few years mention was made of Upper Jurassic (Kimmeridgian and Tithonian) and Lower Cretaceous (Neocomian and Aptian) marine fossils from Dampier Land, a peninsula which lies between the townships of Derby and Broome in the north of Western Australia. The fossils were listed in detail or otherwise mentioned in more or less preliminary stratigraphical descriptions of the area in papers by Brunnschweiler (1951a, 1951 b, 1954, 1957), Guppy (1953), Guppy, Lindner, Rattigan, &amp; Casey (1958), and Fairbridge (1953). A great deal of geological work has been carried out since those preliminary exploration activities, chiefly by the staff of the West Australian Petroleum Pty Ltd (WAPET). The currently accepted stratigraphical picture has recently been presented by McWhae, Playford, Lindner, Glenister, &amp; Balme (1958), and the reader is referred to this paper for the overall situation and the relationships of the formations mentioned in the present descriptions of the fossils. The occurrence of Upper Jurassic and Lower Cretaceous formations in this region has been known for many years, but only in recent years have the nature and extent of the sequences become known in reasonable detail. The only description of Upper Jurassic fossils of this area is found in a short paper by Teichert (1940a). Unfortunately several of the fossil specimens described hereafter were lost in the fire in the Canberra offices of the Bureau of Mineral Resources in April, 1953. The illustrations on plates I and II had to be made up from discoloured and singed photographs, the negatives of which did not survive the fire. Mostly," open" nomenclature is applied even where an obviously new form is in evidence; for new species can only be established where satisfactory type material is still available. The main purpose of this paper is to substantiate earlier statements by showing what fossils have been found, even though this can only be done with the help of photographs which luckily escaped destruction by the fire. Much of the work for this paper was done before mid-1954, when the writer was still a member of the staff of the Bureau of Mineral Resources, and engaged in work on the stratigraphy and palaeontology of the Australian Mesozoic.

South-east Australian Fractured Rock Province hydrogeological inventory

This South-east Australian Fractured Rock Province dataset contains descriptive attribute information for the areas bounded by the relevant spatial groundwater feature in the associated Hydrogeology Index map. Descriptive topics are grouped into the following themes: Location and administration; Demographics; Physical geography; Surface water; Geology; Hydrogeology; Groundwater; Groundwater management and use; Environment; Land use and industry types; and Scientific stimulus.

Groundwater in Australia's fractured rock aquifers is stored in fractures, joints, bedding planes, and cavities within the rock mass, comprising about 40% of the country's groundwater. Much of this water can be utilized for irrigation, town water supplies, stock watering, and domestic use, based on state regulations. Fractured systems account for approximately 33% of all bores in Australia but contribute to only 10% of total extraction due to variable groundwater yield.

Quantifying groundwater movement in fractured rock systems is challenging, as it depends on the distribution of major fractures. Groundwater flow direction is more influenced by the orientation of fractures than hydraulic head distribution. Recharge in fractured rock aquifers is typically localized and intermediate.

In Eastern Australia, New South Wales' Lachlan Orogen, which extends from central and eastern New South Wales to Victoria and Tasmania, is a significant region with diverse lithological units, including deep marine turbidites, shallow marine to sub-areal sediments, extensive granite bodies, and volcano-intrusive complexes. This region contains various mineral deposits, such as orogenic gold, volcanic-hosted massive sulphide, sediment-hosted Cu-Au, porphyry Au-Cu, and granite-related Sn.

Note: The study does not include additional Orogens in the east (New England) and west (Thomson and Delamerian). The Delamerian Orogen is present throughout western Tasmania.

Petrel Sub-basin Marine Survey (GA-0335 / SOL5463) (NLECI Program) - interpreted geomorphic map

The Petrel Sub-basin Marine Environmental Survey GA-0335, (SOL5463) was undertaken by the RV Solander during May 2012 as part of the Commonwealth Government's National Low Emission Coal Initiative (NLECI). The survey was undertaken as a collaboration between the Australian Institute of Marine Science (AIMS) and GA. The purpose was to acquire geophysical and biophysical data on shallow (less then 100m water depth) seabed environments within two targeted areas in the Petrel Sub-basin to support investigation for CO2 storage potential in these areas. This dataset comprises an interpreted geomorphic map.

Interpreted local-scale geomorphic maps were produced for each survey area in the Petrel Sub-basin using multibeam bathymetry and backscatter grids at 2 m resolution and bathymetric derivatives (e.g. slope; 1-m contours). Five geomorphic units; bank, plain, ridge, terrace and valley, were identified and mapped using definitions suitable for interpretation at the local scale (nominally 1:10 000). Maps and polygons were manual digitised in ArcGIS using the spatial analyst and 3D analyst toolboxes.

National Gravity Compilation 2019 includes airborne DGIR 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 includes airborne DGIR image is produced from the 2019 Australian National Gravity Grids B series. These gravity data were acquired under the project No. 202008. The grid The grid represented in this image has a cell size of 0.00417 degrees (approximately 435m). The data are given in units of um/s^2, also known as 'gravity units', or gu. 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. 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 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. Airborne surveys have a line spacing ranging from 0.5 km to 2.5 km. The image shows de-trended global isostatic residual anomalies over Australia and its continental margins. This National Gravity Compilation 2019 includes airborne DGIR image (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 B series.
