Review of the Australian Flood Studies Database

With the average annual cost of floods estimated at $377 million, floods are Australia's most expensive natural hazard. As a result, considerable expenditure is made by government and industry to define flood areas in an effort to reduce the impacts of floods. This work typically involves the creation of reports describing the methodology used, data sources and results of hydrological and hydraulic modelling and damage assessments. While numerous reports are developed each year, there was no centralised record of what studies had been undertaken in Australia at a state/territory or national level until the development of the Australian Flood Studies Database in 2004. 
In 2009 Geoscience Australia reviewed the Australian Floods Studies Database via an online questionnaire. Opinion of the database was sought in three key areas including database functionality and content, and updating the database. The respondents confirmed the usefulness of the existing database content including hydrology and hydraulic scenarios, historical flood events used in the calibration, terrain and floor level surveys, damage assessments, inundation and hazard scenarios, information on what has occurred since a study's completion and related studies. Recurring themes highlighted by the survey respondents include the ability to be able to access the flood study reports and GIS flood layers via the database and be able to input data. Over 170 people completed the survey; 90% of whom were from local government. While only 20% of respondents had used the database, 72% of all respondents to the survey indicated that they would use the database in the future, whether or not they had used the database in the past.
Three main recommendations can be concluded from the survey responses. The first recommendation is that the Australian Flood Studies Database is updated and that the lead agency for floodplain management in each State/Territory be responsible for that update on at least an annual basis. The second recommendation is that the database's existing functionality and content is maintained and further enhanced. The final recommendation is that the database is further publicised.

Maryborough Basin (Pt Clinton,Rockhampton,Heron Is), SE QLD, 1986 (P514), radiometric line data, AWAGS levelled

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 Maryborough Basin (Pt Clinton,Rockhampton,Heron Is), SE QLD, 1986 (P514), radiometric line data, AWAGS levelled were acquired in 1986 by the QLD Government, and consisted of 27866 line-kilometres of data at 1500m line spacing and 150m 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.

Seafloor environments of the eastern Timor Sea, Northern Australia: Total metabolism of seabed sediments.

The Timor Sea and its tropical marine environment support significant and growing economic activity including oil and gas exploration. To reduce uncertainty in decision making regarding the sustainable use and ongoing protection of these marine resources, environmental managers and resource users require sound scientific information on the composition and stability of seabed environments and their biological assemblages. Surveys SOL4934 and SOL5117 to the eastern Joseph Bonaparte Gulf were undertaken in August and September 2009 and July and August 2010 respectively, in collaboration with the Australian Institute of Marine Science, with research collaborations from the RAN Australian Hydrographic Office, the Geological Survey of Canada and the Museum and Art Gallery of the Northern Territory. The purpose of these surveys were to develop biophysical maps, and deliver data and information products pertaining to complex seabed environment of the Van Diemen Rise and identify potential geohazards and unique, sensitive environments that relate to offshore infrastructure. This dataset comprises total metabolism measurements (as dissolved CO2 production) in the upper 2cm of seabed sediments.

Vegetation Type Dataset for Recharge Discharge Project

The source data for this dataset is the draft version of the Dynamic Land Cover Map based on MODIS Data, obtained from Geoscience Australia. 
The Dynamic Land Cover Map presents land cover information for every 250m by 250m area of the country from April 2000 to April 2008. The classification scheme used to describe land cover categories in the Dynamic Land Cover Map conforms to the 2007 International Standards Organisation (ISO) land cover standard (19144-2).  The Dynamic Land Cover Map shows Australian land covers clustered into 34 ISO classes. These reflect the structural character of vegetation, ranging from cultivated and managed land covers (crops and pastures) to natural land covers such as closed forest and sparse, open grasslands. 
This dataset was reclassified into Annuals, Perennials, Water Bodies and Urban Areas.
Annuals - Extraction Sites, Bare Areas, Rainfed Cropping, Irrigated Cropping and Irrigated Pasture and Rainfed Pasture 
Perennials - Wetlands, Forbs (open and closed), Tussock, Alpine and Hummock Grasses (Open, Closed and sparse), Shrubs (open and closed), Rainfed Sugar
Irrigated Sugar and Trees (Open, closed, scattered and sparse)
Water Bodies - Inland Waterbodies and Salt Lakes
To obtain urban areas, the dataset was unioned with the 250k topographic map series obtained from Geoscience Australia.

Performance of national scale smoothed seismicity estimates of earthquake activity rates

Four smoothed seismicity models were submitted for consideration to the 2018 National Seismic Hazard Assessment (NSHA18). Three of the models used fixed smoothing bandwidths, each with slightly different implementations, while the fourth used an adaptive smoothing bandwidth that varies spatially based on earthquake density. In this paper we assess the performance of these models at forecasting activity rates over decadal timescales by using part of the earthquake catalogue used for NSHA18 to develop the models and calculating the log-likelihood of the model activity rates against the remainder of the catalogue. We test the performance of the models at forecasting rates of earthquakes of different magnitudes over different lengths of training and forecast periods, and compare the use of non-declustered and declustered earthquake catalogues. We test for time-dependence by running the comparisons sequentially and using an earthquake catalogue randomised in time. The results are used to evaluate and inform the final implementation of the smoothed seismicity models for calculating 10% in 50 year probability ground motion exceedances for the NSHA18.
This abstract was submitted and presented to the 2017 Australian Earthquake Engineering Society Conference (AEES) ( https://aees.org.au/2017-aees-conference/)

Spencer - 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 Spencer - 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 2018 by the SA Government, and consisted of 49937 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.

An Isotopic Atlas of Australia: a window into the geological evolution of the Australian continent

Australia as it exists today is a product of geological processes that have occurred over its 4.5 billion year history.  Isotopic studies are one approach to understanding the history and evolution of the Australian continent.  Isotope geochronology tells us about the timing of a wide range of geological processes like crystallisation, deformation and cooling of rocks.  Isotope geochemistry informs on the precursor components from which the rocks formed, and can act as 'paleogeophysical' sensors to tell us more about the subsurface.
The Isotopic Atlas of Australia brings together five of the most widely used isotopic systems in geology and delivers publicly available maps and datasets in a consistent format.  This work is unlocking the collective value of decades of investment in data collection, and facilitating qualitative and quantitative comparison and integration with other datasets such as geophysical images. This talk will be an introduction to the world of isotopes as applied to understand geology, and an overview of the Isotopic Atlas recently produced as part of the Exploring for the Future Program.

The geology of the Fitzroy Basin, Western Australia

The Fitzroy Basin in this bulletin refers to that part of the Canning Basin which lies between the Precambrian of the Kimberley Plateau in the north and the Fenton Fault in the south; the bulletin also considers some formations cropping out south of the Fenton Fault. The Canning Basin is the area of Palaeozoic and Mesozoic rocks bounded by the Precambrian of the Kimberley Plateau on the north, and the Pilbara area in the south, and Extending westward on to the continental shelf. Downwarps within the Canning Basin may warrant separate names; the first to be named is the Fitzroy Basin.
