AUSGeoid98 v.1.0 data files: Lake Mackay (sf52-11)

AUSGeoid98 data files contain a 2 minute grid of AUSGeoid98 data covering the Australian region, which you can use to interpolate geoid-ellipsoid separations for the positions required.You can use your own interpolation software, or you can use Geoscience Australia's Windows Interpolation software (Winter). The data files are text files in a standard format that cover the same area as standard topographic map areas. Files covering both 1:250,000 (approximately 100 x 150 km) and 1:1,000,000 (approximately 400 x 600 km) map areas are available. There is a 4 minute overlap on all sides of each area. Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places. AUSGeoid98 deflections of the vertical were computed from the geoid-ellipsoid separation surface, while the AUSGeoid93 deflections of the vertical were computed from OSU91A.

GSWA Devils Creek ppm Uranium Grid Geodetic

The radiometric, or gamma-ray spectrometric method, measures the natural variations in the gamma-rays detected near the Earth's surface as the result of the natural radioactive decay of potassium (K), uranium (U) and thorium (Th). 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 radiometric uranium grid has a cell size of 0.00083 degrees (approximately 84m) and shows uranium element concentration of the Devil's Creek, WA, 1999 in units of parts per million (or ppm). The data used to produce this grid was acquired in 1999 by the WA Government, and consisted of 3935 line-kilometres of data at 300m line spacing and 70m terrain clearance.

Users' guide to PETROG: AGSO's petrography database

PETROG, AGSO's Petrography Database, is a relational computer database of petrographic data obtained from microscopic examination of thin sections of rock samples.  The database is designed for petrographic descriptions of crystalline igneous and metamorphic rocks, and also for sedimentary petrography.  A variety of attributes pertaining to thin sections can be recorded, as can the volume proportions of component minerals, clasts and matrix.
PETROG is one of a family of field and laboratory databases that include mineral deposits, regolith, rock chemistry, geochronology, stream-sediment geochemistry, geophysical rock properties and ground spectral properties for remote sensing.  All these databases rely on a central Field Database for information on geographic location, outcrops and rock samples.  PETROG depends, in particular, on the Field Database's SITES and ROCKS tables, as well as a number of lookup tables of standard terms.  ROCKMINSITES, a flat view of PETROG's tables combined with the SITES and ROCKS tables, allows thin-section and mineral data to be accessed from geographic information systems and plotted on maps.
This guide presents an overview of PETROG's infrastructure and describes in detail the menus and screen forms used to input and view the data.  In particular, the definitions of most fields in the database are given in some depth under descriptions of the screen forms - providing, in effect, a comprehensive data dictionary of the database.  The database schema, with all definitions of tables, views and indexes is contained in an appendix to the guide.

Unveiling hidden treasures—Exploring new geological insights into the Delamerian Margin

In outback Australia, beneath a blanket of red earth, lies an ancient part of the continent that formed over 500 million years ago. The Delamerian Orogen.&nbsp;

Through a multi-disciplinary approach to geological and geophysical data collection and integration, we shed new insights into&nbsp;Delamerian Orogen—its evolution and its mineral prospectivity. &nbsp;

As part of Geoscience Australia-led Exploring for the Future Program, this talk will speak to how we sought&nbsp;to unite disjointed geological architecture of the eastern Delamerian Orogen into a cohesive framework to enable us to understand the regional mineral systems and enhance the exploration potential of this under-explored region.&nbsp;

Ecology / Infaunal morphospecies identifications from the Vlaming Sub-basin (GA0334)

The Vlaming Sub-basin Marine Survey GA-0334 was undertaken in March and April 2012 as part of the Commonwealth Government's National CO2 Infrastructure Plan (NCIP). The purpose was to acquire geophysical and biophysical data to help identify sites suitable for the long term storage of CO2 within reasonable distances of major sources of CO2 emissions.
This dataset contains identifications of animals collected from 32 Van Veen grabs deployed during GA-0334. Sediment was elutriated for ~ 5 minutes over a 500um sieve. Retained sediments and animals were then preserved in 70% ethanol for later laboratory sorting and identification (see `lineage'). During sorting, all worms were separated and sent to Infaunal Data Pty Ltd (Lynda Avery) for identification to species or operational taxonomic unit (OTU). Lynda Avery completed identifications on 17 April 2013, and specimens were lodged at the Museum of Victoria. All other taxa were identified to morphospecies at GA by an ecologist.
Gray shading indicates taxa identified to species level  by Lynda Avery (Refer to GeoCat # 76463 for raw data of species identifications by taxonomist); all other taxa were identified to morphospecies. Data is presented here exactly as delivered by the taxonomist/ecologist, and Geoscience Australia is unable to verify the accuracy of the taxonomic identifications. Stations are named XXGRYY where XX indicates the station number, GR indicates Van Veen grabs, and YY indicates the sequence of grabs deployed (i.e. the YYth grab on the entire survey). H indicates heavy fraction animals and HS indicates animals found on a sponge. The dataset is current as of November 2014, but will be updated as taxonomic experts contribute.
See GA Record 2013/09 for further details on survey methods and specimen acquisition.

Petroleum Systems Analysis of the Northern Houtman Sub-basin - APPEA Conference 2017

Interpretation of newly acquired seismic data in the northern Houtman Sub-basin (Perth Basin) suggests the region contains potential source rocks similar to those in the producing Abrolhos Sub-basin. The regionally extensive late Permian–Early Triassic Kockatea Shale has the potential to contain the oil-prone Hovea Member source interval.  Large Permian syn-rift half-graben, up to 10 km thick, are likely to contain a range of gas prone source rocks. Further potential source rocks may be found in the Jurassic-Early Cretaceous succession, including the Cattamarra Coal Measures, Cadda shales and mixed sources within the Yarragadee Formation. 
This study investigates the possible maturity and charge history of these different source rocks. A regional pseudo-3D petroleum systems model is constructed using new seismic interpretations. Heat flow is modelled using crustal structure and possible basement composition determined from potential field modelling, and subsidence analysis is used to investigate lithospheric extension through time. The model is calibrated using temperature and maturity data from 9 wells in the Houtman and Abrolhos sub-basins. Source rock properties are assigned based on an extensive review of TOC, Rock Eval and kinetic data for the offshore northern Perth Basin. 
Petroleum systems analysis results show that Permian, Triassic and Early Jurassic source rocks may have generated large cumulative volumes of hydrocarbons across the northern Houtman Sub-basin, whilst Middle Jurassic‒Cretaceous sources remain largely immature. However the timing of hydrocarbon generation and expulsion with respect to trap formation and structural reactivation is critical for the successful development and preservation of hydrocarbon accumulations.

Evolving and Sustaining Ocean Best Practices to Enable Interoperability in the UN Decade of Ocean Science for Sustainable Development

The UN Decade of Ocean Science for Sustainable Development (Ocean Decade) challenges the ocean research community to map and understand the changing ocean to inform and stimulate social and economic development, while conserving marine ecosystems. To achieve these objectives, the methodologies that generate data and information about the ocean need to interoperate with unprecedented depth and scale. For this, we must expand global participation in ocean science through a new and coherent approach to best practice development, supporting capacity development and sharing across a dramatically expanded range of communities. Here, we present perspectives on this issue gleaned from the ongoing development of the UNESCO Intergovernmental Oceanographic Commission (IOC) Ocean Best Practices System (OBPS). The OBPS is collaborating with individuals and programs around the world to transform the way ocean methodologies are managed, in strong alignment with the Outcomes envisioned by the Ocean Decade. However, significant challenges remain. These include the haphazard management of methodologies across their life cycle, the ambiguous endorsement of what is “best” and when/where, and the inconsistent access to best practices across disciplines and cultures. To help address these challenges, this Perspective recommends how we - as a global marine science community - can ensure our methodological know-how supports the Ocean Decade outcomes through: promoting convergence of methodologies into context-dependent best practices; incorporating contextualized best practices into Ocean Decade Actions; clarifying who endorses which method and why; creating a global network of complementary ocean practices systems; and ensuring broader consistency and flexibility in international capacity development.
