NT Road Surveys 1987-1997 Musgrave Block (P198858), gravity point data

Gravity data measures small changes in gravity due to changes in the density of rocks beneath the Earth's surface. 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 NT Road Surveys 1987-1997 Musgrave Block (P198858) contains a total of 193 point data values acquired at a spacing of 800 metres. The data is located in NT and were acquired in 1988, under project No. 198858 for None.

Molecular profiles of the middle Cambrian Arthur Creek Formation and Thorntonia Limestone, southern Georgina Basin: A case study from CKAD0001

The Georgina Basin is a Neoproterozoic to Lower Devonian sedimentary basin covering 325 000 km2 of western Queensland and the Northern Territory. It is a northwest-southeast-trending extensional basin, with conventional and unconventional hydrocarbon exploration targets in the southern depocentres within the middle Cambrian Arthur Creek Formation (AC Fm). Recent biostratigraphic work using agnostid trilobites [1] has determined that the prospective hot shale (so called due to high gamma-ray log values) at the base of the AC Fm in the Dulcie Syncline is older (Templetonian) than thehot shale in the Toko Syncline, which is of Floran age. To complicate the stratigraphy further, the Thorntonia Limestone (Th Lst) in the Undilla Sub-basin is also Templetonian in age, the same age as the AC Fm in the Dulcie Syncline and younger than the Th Lst in the Dulcie Syncline (Ordian). In this study molecular analyses of the AC Fm and the Th Lst from the CKAD0001 well were undertaken in order to distinguish between the two formations and assist with future correlations.

MRTAS SW Tasmania 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 MRTAS SW Tasmania doserate grid geodetic has a cell size of 0.00042 degrees (approximately 40m) and shows the terrestrial dose rate of the South West Tasmania, Tas, 2001 (WTRMP Area D). The data used to produce this grid was acquired in 2000 by the TAS Government, and consisted of 13701 line-kilometres of data at 200m line spacing and 80m terrain clearance.

Seeing the floods through the trees, Using adaptive SWIR thresholds to map inundation under persistent vegetation

Accurate information about the extent, frequency and duration of forest inundation is required to inform ecological, biophysical and hydrological models and enables floodplain managers to quantify the efficacy of flood mitigation/modification activities. Open water classifiers derived from optical remote sensing typically underestimate or fail to detect floodplain forest inundation. This paper presents a new method for detecting forest inundation dynamics using freely available Landsat and Sentinel 2 data, referred to as short-wave infrared mapping under vegetation. The method uses a dynamic threshold that accounts for the additional shortwave infrared reflectance caused by the presence of tree canopies over floodwater. The method is demonstrated at five Ramsar listed River Red Gum floodplain forest wetlands in southeastern Australia. Accuracy assessment based on independent drone imagery from a wide range of vegetated wetlands showed an absolute accuracy of 67%–70% and a fuzzy accuracy of 81%–83%. We found the method is conservative, and underestimates inundation (16%–18%) but very rarely misclassifies dry pixels as inundated (0.3%–0.6%). When compared to river gauge data, the method shows similar trends to an open water classifier (i.e., the area of inundated vegetation increases with increasing river height). The method is conservative compared to lidar-based floodplain inundation models but can be applied wherever cloud-free scenes of Landsat or Sentinel 2 have been acquired, thereby enabling floodplain managers with the ability to quantify changes in inundation dynamics in places/time-periods where lidar is unavailable.

Central Bowen Basin, Qld, 2003 (P929), 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 Central Bowen Basin, Qld, 2003 survey were acquired in 2003 by the QLD Government, and consisted of 65476 line-kilometres of data at 400m line spacing and 80m 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.

A global probabilistic tsunami hazard assessment

Large tsunami occur infrequently but have the capacity to cause enormous numbers of
casualties, damages to the built environment, critical infrastructure, and economic losses. A
sound understanding of tsunami hazard is required to underpin management of these risks,
and while tsunami hazard assessments are typically conducted at regional or local scales,
globally consistent assessments are required to support international disaster risk reduction
eorts. This study presents a global scale probabilistic tsunami hazard assessment (PTHA),
extending previous global scale assessments based largely on scenario analysis. Only earth-
quake sources are considered, representing about 80% of damaging tsunami events. Globally
extensive estimates of tsunami runup height are derived at various exceedance rates, and
the associated uncertainties are quantied. Epistemic uncertainties in the exceedance rates
of large earthquakes often lead to large uncertainties in the tsunami runup. Deviations be-
tween the modelled tsunami runup and event observations are quantied, and found to be
larger than suggested in previous studies. Accounting for these deviations in the PTHA is
important, as it leads to a strong increase in predicted tsunami runup for a given exceedance
rate.

Late Cambrian trilobites from the Chatsworth Limestone, western Queensland

The trilobite faunas described in this Bulletin are exclusively from the Chatsworth Limestone sensu stricto, as it occurs in the immediate neighbourhood of Chatsworth Homestead, 80 km south-southeast of Duchess, in western Queensland (Fig. 1). The outcrops straddle the Duchess and Boulia 1:250000 Sheet areas, and form the central portion of the Burke River Structural Belt (Shergold, 1975, pp. 4-7; in Shergold, Druce et al., 1976, pp. 4-5). "Although trilobites have been described (Opik, 1963, 1967) from the underlying Pomegranate Limestone, at Pomegranate Creek, 19 km north of 'Chatsworth', no material from the Chatsworth Limestone s.s. has been illustrated previously. Those trilobites presently described are from collections made during initial field mapping of the Boulia Sheet area in 1957-60 (Casey, 1968; Casey et al., 1960), and the Duchess area in 1958 (Carter &amp; Opik, 1963; 6pik, 1963). Frome-Broken Hill Pty Ltd collected two samples from the basal Chatsworth Limestone near 'Chatsworth' in 1958 (Taylor, 1959). Subsequently, collections were assembled by the BMR Northwest Queensland Phosphate Group in 1967 (de Keyser et al., in de Keyser, 1968), by the author in 1969, and by B.M. Radke during the course of 1:100 000 scale mapping. by the BMR Georgina Basin Project in 1974-75. Material is also currently. Available from two BMR stratigraphic boreholes, Boulia No. 6 and Duchess No. 13 (Fig. 2 and Appendix 3), drilled for the Georgina Basin Project in 1974.

New Insights into the Post-rift Depositional History of the Mentelle Basin Based on Seismic Facies Mapping

New 2D seismic data acquired in the Mentelle Basin by Geoscience Australia in 2008-09 has been used for a seismic facies study of the post-rift succession. The Mentelle Basin is a large deep to ultra deep-water, frontier basin located on Australia's southwestern margin about 200 km southwest of Perth. The study focused on the post-rift sequences deposited following the breakup between Australia and Greater India. Stratigraphic wells DSDP 258 and DSDP 264 provide age and lithological constraints on the upper portion of the post-rift succession down to mid-Albian strata. The depositional environment and lithology of the older sequences are based on analysis of the seismic facies, stratal geometries and comparisons to the age equivalent units in the south Perth Basin. Fourteen seismic facies were identified based on reflection continuity, amplitude and frequency, internal reflection configuration and external geometries. They range from high continuity, high amplitude, parallel sheet facies to low continuity, low amplitude, parallel, subparallel and chaotic sheet, wedge and basin-fill facies. Channel and channel-fill features are common in several facies as well as a mounded facies (probably contourite) and its associated ponded turbidite fill. A progradational sigmoidal to oblique wedge facies occurs at several stratigraphic levels in the section. A chaotic mound facies, probably comprising debrite deposits, has a localised distribution. Seismic facies analysis of the post-rift sequences in the Mentelle Basin has contributed to a better understanding of the depositional history and sedimentation processes in the region, as well as provided additional constraints on regional and local tectonic events.
