Report on the Interpretation and Mapping of Natural Hydrocarbon Seeps and Other Features on the South West Margins Off the Western Australian Coast using Satellite Radar Data

The processing, interpretation and mapping of slicks offshore of the South West Margins using ten ERS satellite radar scenes and four Radarsat scenes has been completed successfully.
All slick interpretations have been attributed with a hydrocarbon likelihood Level ranging from Level 2 to Level 4 with Level 2 being the most likely.  Given the absence of actual field data, no Level 1 slicks have been mapped (see Glossary of Slick and Other Interpretations, p3 below). 
For all the fourteen scenes interpreted and mapped, there is only one Level 2 slick.  This significant slick is located on the western edge of scene ERS 2 WO 01907-01 Orbit 5883.
No locations have been provided of the sources of mapped slicks.  Although an approximate point source would normally be provided for Level 2 slicks, the only Level 2 slick mapped (as above) is not complete as it is on the edge of the image (and presumably would continue on to an adjacent image acquired at the same time if it were available) and given the depth to sea floor of between 2,500m to 3,000m, it is not possible to provide a point source. 
Likewise, while an approximate point source would normally be provided for Level 3 slicks, given the depth to sea floor in the locations of the two Level 3 slicks mapped (same scene as for the Level 2 slick) of between 2,500m to 5,500m, it is not possible to provide a point sources.  As per normal, Level 4 slicks are not provided with a source point.
Many of the Level 4 slicks are located along the coastline in or near to the surf break zone (some possibly adjacent to rocky outcrops) and as such are regarded as false slicks as they most likely relate to differences in sea surface conditions and not to the formation of hydrocarbons.

Childara - TMI grid (AWAGS)

Total magnetic intensity (TMI) data measures variations in the intensity of the Earth's magnetic field caused by the contrasting content of rock-forming minerals in the Earth crust. Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock. The data 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 Childara - TMI grid (AWAGS) has a cell size of 0.0004 degrees (approximately 41m). The units are in nanoTesla (or nT). The data used to produce this grid was acquired in 2017 by the SA Government, and consisted of 135047 line-kilometres of data at 200m line spacing and 60m terrain clearance. To constrain long wavelengths in the grid, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey grid.

GSWA East Canning 3 Doserate 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. The terrestrial dose rate grid is derived as a linear combination of the filtered K, U and Th grids. A low pass filter is applied to this grid to generate the filtered terrestrial dose rate grid.
This GSWA East Canning 3 Doserate Grid Geodetic has a cell size of 0.00083 degrees (approximately 89m) and shows the terrestrial dose rate of the Stansmore, WA, 2010 (East Canning 3). The data used to produce this grid was acquired in 2010 by the WA Government, and consisted of 122578 line-kilometres of data at a line spacing between 200m and 400m, and 50m terrain clearance.

AGSO's Catalog of Everything In: Proceedings of the 4th National Forum on Information Management and GIS in the Geosciences

With the increasing emphasis on electronic rather that paper products, the need for adequate metadata is becoming more and more pressing.  The new AGSO Catalog is designed to address this problem at the corporate level.  Developed from the AGSO Products Database, the AGSO Catalog is designed to encompass most of AGSOs outputs, datasets and resources.  It does this with the help of various intranet and Web interfaces.  Projects or authors must initiate Catalog entries, for without an acceptable metadata a product cannot be sold by the Sales Centre, or permission to publish will not be granted.  The Catalog is the key to future systems of information distribution and sales.  It will permit us to go directly from the metadata to the electronically stored objects, thus enabling automated information distribution and electronic commerce.

AUSGeoid98 v.1.0 data files: Deniliquin (si55-13)

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.

Floods: Hazards, modelling and risk assessment

Floods are estimated to be the most costly natural disaster in Australia. The average direct annual cost of flooding between 1967 and 1999 has been estimated at A$314 million (BTE 2001). Economic loss due to flooding varies widely from year to year and is dependent on a number of factors for example, flood severity and location. The most costly year for floods was 1974, with a total cost of A$2.9 billion (BTE 2001). Some major floods and their estimated cost in 1998 values (Agriculture and Resource Management Council of Australia and New Zealand, ARMCANZ 2000) include:
Brisbane floods, Summer 1974, A$700 million damage
Victoria floods, Spring 1993, A$320 million damage
Hunter River floods, 1955, A$500 million damage.

Flooding has a major impact on our communities. There have been ninety-nine recorded deaths from floods between 1967 and 1999 and 1019 recorded injuries (Bureau of Transport Economics, 2001). The impact of flooding be devastating, with the affects often extending beyond the zone of inundation, as can be seen in Figure 1. The floods in regional Queensland and NSW in 2001, for example, resulted in an increase in the cost of fruit and vegetables in Australia

Arafura Marine Park Bathymetry Flythrough

This flythrough highlights seabed environments within two areas of Arafura Marine Park offshore northern Australia; Money Shoal and Pillar Bank. Located 250 km to the northeast of Darwin within the Arafura Sea, the marine park extends to the limit of Australia’s exclusive economic zone, covering an area of 22,924 km2. Money Shoal is an isolated carbonate reef platform on the continental shelf that rises from 70 m to shallow subtidal depths and supports a diverse coral and demersal fish community. The surrounding seabed comprises muddy substrate characterized by extensive fields of pockmark, interpreted as evidence for fluid escape from organic-rich sediment. Pillar Bank, in contrast, is representative of the deeper (150 – 200 m depths) outer shelf area of the marine park that supports sparse benthic communities of filter feeders on local outcrops of hard substrate, surrounded by expanses of muddy substrate. Demersal fish are also present, as observed using baited underwater cameras. Bathymetry data and seafloor imagery for this flythrough was collected in November 2020 by Geoscience Australia (GA) and the Australian Institute of Marine Science (AIMS) on board RV Solander during survey SOL7491/GA0366. Funding was provided by the Australian Government’s National Environmental Science Program (NESP) Marine Biodiversity Hub, with co-investment by GA and AIMS.

Community Vulnerability to Natural Hazards: Contributing to total risk assessment

The impact of natural hazards on Australian communities can be devastating. After such events, the devastation is commonly measured in terms of costs to property, businesses and infrastructure. The challenge is to better understand our communities so that a more comprehensive management of total risk can be taken. Such a task requires a multi-disciplinary approach, and Geoscience Australia is collaborating with the Bureau of Meteorology, Emergency Management Australia, Local Government Agencies and Universities to develop a better understanding of how natural hazards affect communities.
