1 second SRTM Derived Hydrological Digital Elevation Model (DEM-H) version 1.0

The 1 second SRTM derived DEM-H Version 1.0 is a 1 arc second (~30 m) gridded digital elevation model (DEM) that has been hydrologically conditioned and drainage enforced. The DEM-H captures flow paths based on SRTM elevations and mapped stream lines, and supports delineation of catchments and related hydrological attributes. The dataset was derived from the 1 second smoothed Digital Elevation Model (DEM-S; ANZCW0703014016) by enforcing hydrological connectivity with the ANUDEM software, using selected AusHydro V1.6 (February 2010) 1:250,000 scale watercourse lines (ANZCW0503900101) and lines derived from DEM-S to define the watercourses. The drainage enforcement has produced a consistent representation of hydrological connectivity with some elevation artefacts resulting from the drainage enforcement. A full description of the methods is in preparation (Dowling et al., in prep).
This product is the last of the Version 1.0 series derived from the 1 second SRTM (DSM, DEM, DEM-S and DEM-H) and provides a DEM suitable for use in hydrological analysis such as catchment definition and flow routing.

Offshore NW Tasmania, Tas, 2008 (P1181), magnetic line data, AWAGS levelled

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.
 These line dataset from the Offshore NW Tasmania, Tas, 2008 survey were acquired in 2008 by the TAS Government, and consisted of 43783 line-kilometres of data at 800m line spacing and 85m terrain clearance. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data. This survey data is essentially levelled to AWAGS.

Devonian and Carboniferous brachiopods from Bonaparte Gulf Basin, northwestern Australia

This Bulletin describes the brachiopod fauna of the Devonian and Carboniferous (Frasnian to early Namurian) platform sediments of the Bonaparte Gulf Basin in northwestern Australia (Fig. 1). It is part of a comprehensive study of the Bonaparte Gulf Basin begun by the Bureau of Mineral Resources in 1963, and follows an earlier study by Thomas (1970), started in the mid-1950's, on brachiopods from the Carnarvon, Canning, and Bonaparte Gulf Basins. Thomas's material from the Bonaparte Gulf Basin, with the exception of that from the Septimus Limestone at Mount Septimus, came largely from samples collected in reconnaissance surveys. Other earlier work on brachiopods from the Bonaparte Gulf Basin includes that of Veevers (1959b) on rhynchonellids and a productacean, and Thomas (1965) on Delepinea. A comprehensive description of the Devonian and Carboniferous geology of the basin is given by Veevers, Roberts (1968).

Tsunami Modelling Validation: The Impact of the 2004 Indian Ocean Tsunami on Geraldton, Western Australia

In response to the devastating Indian Ocean Tsunami (IOT) that occurred on the 26th of December 2004, Geoscience Australia developed a framework for tsunami risk modelling. The outputs from this methodology have been used by emergency managers throughout Australia. For GA to be confident in the information that is being provided to the various stakeholders' validation of the model and methodology is required.
While the huge loss of life from the tsunami was tragic, the IOT did provide a unique opportunity to record the impact of a tsunami on the coast of Western Australia. Eight months after the tsunami a post-disaster survey was conducted at various locations along the coast and maximum run-up was determined from direct observational evidence or anecdotal accounts. In addition tide gauges located in harbours along the coast also recorded the tsunami and provide a timeseries account of the wave heights and frequency of the event. 
This study employs the tsunami hazard modelling methodology used by Geoscience Australia (GA) to simulate a tsunami scenario based on the source parameters obtained from the Boxing Day earthquake of 2004. The model results are compared to observational evidence from satellite altimetry, inundation surveys and tide gauge data for Geraldton, a community on the Western Australian coast. 
Results show that the tsunami model provides good estimates of the wave height in deep water and also run up in inundated areas and it importantly matches the timing of the first wave arrivals. However the model fails to reproduce the timeseries data of wave heights observed by a tide gauge in Geraldton harbour. The model does however replicate the occurrence of a late arriving (16 hrs after first arrival) wave packet of high frequency waves. This observation is encouraging since this particular wave packet has been noted elsewhere in the Indian Ocean and caused havoc in harbours many hours after the initial waves had arrived and dissipated.

National ASTER geoscience map - flyer

National ASTER geoscience map 
The ASTER Geoscience Maps is the first public, web-accessible, continent-scale product release from the ASTER Global Mapping data archive. 
It represents a successful collaborative Australian ASTER Initiative, led by the Western Australian Centre of Excellence for 3D Mineral Mapping,  and many  State, Territory and Commonwealth agencies along with international partners. ASTER is the first geoscience-tuned Earth observation system that has acquired three near-complete coverages of the Earth's land surfaces.  
These geoscience maps are released in GIS format as 1:1M map-sheet tiles, from 3000 ASTER scenes of 60x60km. Each scene was cross-calibrated and validated using independent Hyperion satellite imagery.
The new ASTER geoscience products range in their application from local to continental scales, and their uses include mapping of soils for agricultural and environmental management, such as estimating soil loss, dust management and water catchment modelling. They will also be useful for resource exploration, showing host rock, alteration and regolith mineralogy and providing new mineral information at high spatial resolution (30m pixel). This information is not currently available from other pre-competitive geoscience data.

A Framework for Modelling Shoreline Response to Clustered Storm Events: Case Studies from Southeast Australia

Coastal communities in Australia are particularly exposed to coincident natural hazards, whereby tropical cyclones and extra-tropical storms cause damage to infrastructure and shorelines from severe wind, flood and storm surge. Because the climatic drivers of severe storms are stronger under certain conditions (e.g. during La Ni±a periods for tropical cyclones), these events can repeatedly impact the coast over periods of weeks to months. Historically, major episodes of beach erosion along southeast Australia have occurred during every decade over the last century, with the most severe in 1974 resulting from two extra-tropical storms in two months. 
While the process of beach erosion is well understood in general terms, the response of a specific sector of coast to clustered storms may not be. For effective coastal management, this site specific knowledge becomes essential. Here we present a framework for integrating coastal geomorphology and coastal engineering approaches to model shoreline response to clustered storms at a spatial scale that can directly inform management agencies. We focus on two case study areas in southeast Australia, the beaches of the Adelaide metropolitan coast (South Australia) and Old Bar beach (central New South Wales) where erosion is a management priority. 
For each site we adopt the coastal sediment compartment as the functional management unit, mapped for the Australian continent at multiple spatial scales, and use sub-surface information (boreholes, ground penetrating radar profiles) to estimate sediment volumes in the upper beach to foredune. These data are then used to inform shoreline response modelling linked to an event time series (observed and hind cast) as a separate project component. Future work includes assessment of `at-risk infrastructure at each site. This paper is a contribution to the Bushfire and Natural Hazard Cooperative Research Centre project Storm surge: Resilience to clustered disaster events on the coast.

History of geoscientific investigations in West Kalimantan, Indonesia

The first reliable geological data from journeys by Europeans into the interior of Kalimantan between 1816 and 1850 came from Schwaner. Dedicated geological investigations started in 1850 with the establishment of a Mines Department (Mijnwezen), which sent the geologist Everwijn on eight trips (1853-1857) to check reported mineral occurrences and prepare geological maps and reports. Results were discouraging. In 1879, a 20 year period of mineral investigations and geological mapping was initiated by van Schelle and continued by Wing Easton. It covered the south Sambas, Singkawang, and western Sanggau Quadrangles. Posewitz in 1892 published an English translation of his review of work done since 1826. In 1883-1884, the eastern region of West Kalimantan was for the first time geologically reconnoitred by a private expedition led by Molengraaff. After Wing Eastons departure in about 1900, there was a hiatus in field work, though several consolidating reviews were published. From 1923 to 1932, another systematic mapping project covered most of West Kalimantan, resulting in reports on the eastern and western regions.  Geological and mining activities were reduced during and after World War II. New legislation in 1967 promoted foreign investment, leading to regional searches fur various minerals and increased geological research. Since 1972 several countries including Australia have undertaken mapping projects jointly with Indonesian government departments, using a wide range of survey methods.
