Streaky Bay - ground elevation geoid grid

Digital Elevation data record the terrain height variations from the processed point- or line-located data recorded during a geophysical survey. This Streaky Bay - ground elevation geoid grid is elevation data for the Streaky Bay Airborne Magnetic Radiometric and DEM survey, SA, 2018. This survey was acquired under the project No. 1308 for the geological survey of SA. The grid has a cell size of 0.0004 degrees (approximately 41m).  This grid contains the ground elevation relative to the geoid for the Streaky Bay Airborne Magnetic Radiometric and DEM survey, SA, 2018. It represents the vertical distance from a location on the Earth's surface to the geoid. The data are given in units of meters. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.

Earth science abstracts, Papua New Guinea, to 1971

Since the first visits by European explorers nearly five hundred years ago, the islands of New Guinea have been visited by explorers and scientists from many nations, including England, Portugal, Netherlands, Germany, Spain, France, Italy, Russia, America, Japan, and Australia. Early contacts ranged from brief watering and careening stays to exploratory cruises charting shorelines. During the 19th century, when German and British colonial administrations were being established, exploration was carried out during border-demarcation surveys, by expeditions mounted specifically to explore the interior of the island, and by mission and administration patrols. Since late in the 19th century a considerable volume of information has been collected by scientific expeditions organized by overseas institutions or governments, by petroleum exploration groups, and by mineral prospecting and mining groups and individuals. In recent years many overseas mining and prospecting companies have been active. All these ventures have contributed to our knowledge of the geology and geomorphology of the island. At times the published written record of investigations has been fragmentary and obscure, at others comprehensive and readily available. It is the aim of this bibliography to bring together as much as possible of the published data in the fields of geology, geomorphology, and pedology. For practical reasons the scope of its coverage has been limited to that part of the island system east of meridian 141 Â°E. West of this meridian is Irian Jaya; east of it are New Guinea and the neighbouring islands. Current official place names have been used throughout the text.

GSWA Trayning potassium grid geodetic

This GSWA Trayning potassium grid geodetic is an airborne-derived radiometric potassium window countrate grid for the Trayning, WA, 1997 survey. 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 GSWA Trayning potassium grid geodetic radiometric potassium window countrate grid has a cell size of 0.00035 degrees (approximately 36m). The data are in units of counts per second (cps). The data used to produce this grid was acquired in 1997 by the WA Government, and consisted of 12657 line-kilometres of data at 150m line spacing and 50m terrain clearance.

Deep Structure of the Joint Development Zone and Adjacent Areas, Timor Sea : Cruise Proposal :Project 121.36

The Joint Development Zone (JDZ) and adjacent areas cruise is part of a program beingundertaken by AGSO, to determine the structural architecture of the northwestern margin ofAustralia and the influence of structuring on the location, migration and trapping ofhydrocarbons in the region. The major objectives of the cruise are:
1) to determine the regional structural framework of the eastern Timor Sea region by examiningthe boundaries between the major structural elements along a series of transects;
2) to provide modern regional seismic tie lines through key wells in the region to facilitateprovince-wide correlations;
3) to determine the deep crustal structure of the Sahul Syncline, Sahul Platform, Timor Troughand Malita Graben;
4) to examine the effects of the deep crustal structure and their various phases of reactivationon the stnitural development of the region.
To meet these objectives it is proposed that the R V Rig Seismic collect approximately 2600km of deep crustal (16 sec record length) multichannel seismic and other geophysical data along13 lines in and around the JDZ. The proposed lines tie major wells in the region. Wherepossible the lines are orthogonal to the principal trends in the region. Some strike lines areincluded to assist the regional ties between wells and existing data sets.

AusSeabed Bathymetry Holdings

This record was superseded on 30/08/2024 with approval from the Director, National Seabed Mapping as it has been superseded by eCat 140124. 
This dataset represents the current extent of bathymetry datasets held by AusSeabed as of January 2019. This dataset is live and will continue to be augmented as coverage is supplied from respective AusSeabed partners. Surveys have been conducted by a wide range of organisations and countries, both inside and outside of Australia's EEZ and for various purposes. Each polygon contains metadata describing the nature of data collection, including details of the survey, as well as the principle investigator of the project. Not all surveys are currently available for download; if available, the Data Access URL attribute will indicate how to access the survey data. Polygons are based on a 500m gridding of the survey data, so may not be representative of the true survey extent when viewed at large scale.

Standard curves for the magnetic anomalies due to spheres

Standard curves for interpretation of the magnetic anomalies due to spheres have been derived. The anomalies in the vertical component, and the horizontal component in the direction of the traverse, are each found to be represented by a single family of curves. The horizontal component is found to be not represented by a single family, and separate curves for each field inclination and traverse azimuth are presented. Curves for the anomaly in the total intensity were not computed.

Onshore Basin Inventory Volume 2: The Canning, Perth and Officer basins

A large proportion of Australia’s onshore sedimentary basins remain exploration frontiers. Industry interest in these basins has recently increased due to the global and domestic energy demand, and the growth in unconventional hydrocarbon exploration. In 2016, Geoscience Australia released an assessment of eight central Australian basins that summarised the current status of geoscientific knowledge and petroleum exploration, and the key questions, for each basin. This publication provides a comprehensive assessment of the geology, petroleum systems, exploration status and data coverage for additional three basins in western and central Australia: the Canning, Perth and Officer basins.  The Perth and Canning basins are producing petroleum basins, however, they may be regarded as frontier basins for unconventional hydrocarbon resources. The Officer Basin is a large, unproven frontier basin which has seen little exploration to date.
