Summary Of Data And Results Carnarvon Basin, Western Australia Exmouth Gulf Marine Seismic Survey Whaleback Seismic Survey Of West Australian Petroleum Pty Limited

A reconnaissance marine reflection seismic survey was conducted in 1961 by Seismograph Service Limited for West Australian Petroleum Pty Limited. The survey took place within the Carnarvon Basin in Western Australia, and covered Exmouth Gulf and the open coastal waters along the west coast of Western Australia from Frazer Island to Bernier Island (see Fig. 1). The project areas fall within Permit to Explore 28H.
The survey was a two-boat operation. In the Exmouth Gulf area the survey was controlled by a Lorac radio navigational system, and along the west coast positioning was determined by sextant angle measurements to shore beacons and landmarks. All shots were recorded on magnetic tapes which were processed into variable-area record sections.
The purpose of the survey was to obtain additional information on the regional geology and to map the extension of known structures in the North-West Cape region of the Carnarvon Basin. Information was also sought on the nature of the pre-Cretaceous to post-Palaeozoic faulting. The survey commenced on 15th July, 1961, and terminated on 20th August, 1961; a total of 753 miles of traverse was shot.
The survey indicated that Exmouth Gulf is essentially synclinal in character in the Cretaceous and Tertiary sediments. Several major pre-Cretaceous fault trends which had already been mapped on land with the seismograph were followed beneath the Gulf. A pre-Cretaceous anticlinal axis underlies the Cape Range Anticline both to the north and to the south of the surface expression of the structure. An anticline was located trending north in the eastern part of the Gulf. A Cretaceous anticline near and parallel to the coast near Cardabia may be the extension of the Rough Range Anticline.
To the south of Point Maud, the survey provided a much-needed tie between the Rough Range-Cape Range area and the structurally complex area round the Salt Marsh. Some structural features were found in this southern area and the trend of major faults was established.
The geophysical operation undertaken in the Exmouth Gulf area, Western Australia, was subsidized under the Petroleum Search Subsidy Act 1959.

Darwin Harbour Habitat Mapping Program: Predicted 13C isotope

This resource contains a predicted 13C isotope grid for the greater Darwin Harbour region as part of a baseline seabed mapping program of Darwin Harbour and Bynoe Harbour. This project was funded through offset funds provided by an INPEX-led Ichthys LNG Project to the Northern Territory Government’s Department of Environment and Natural Resources (NTG-DENR) with co-investment from Geoscience Australia (GA) and the Australian Institute of Marine Science (AIMS). The intent of this program is to improve knowledge of the marine environments in the Darwin and Bynoe Harbour regions by collating and collecting baseline data that enable the creation of thematic habitat maps and information to underpin marine resource management decisions. The predicted 13C isotope grid was derived from a compilation of multiple surveys undertaken by GA, AIMS and NTG-DENR between 2011 and 2017, including GA0333 (Siwabessy et al., 2015), GA0341 (Siwabessy et al., 2015), GA0351/SOL6187 (Siwabessy et al., 2016), GA4452/SOL6432 (Siwabessy et al., 2017), GA0356 (Radke et al., 2017), and GA0358 and GA0359 (Radke et al., 2018), adding to those from previous surveys GA4425 and GA0333 collected by GA, AIMS, NTG-DENR and Darwin Port Authority.

Broken Hill - Euriowie Gravity (P199426), 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 Broken Hill - Euriowie Gravity (P199426) contains a total of 2013 point data values acquired at a spacing between 50 and 500 metres. The data is located in NSW and were acquired in 1994, under project No. 199426 for CRA Exploration Pty Ltd.

Results of Two Dry-season Surveys of Keppel Bay and Casuarina Creek: Biogeochemical Properties of the Water Column and Underlying Sediments

The Fitzoy Estuary is one of several macrotidal estuaries in tropical northern Australia that face ecological change due to agricultural activities in their catchments. The biochemical functioning of such macrotidal estuaries is not well understood in Australia, and there is a pressing need to identify sediment, nutrient and agrochemical pathways, sinks and accumulation rates in these extremely dynamic environments. This is particularly the case in coastal northern Queensland because the impact of water quality changes in rivers resulting from vegetation clearing, changes in land-use and modern agricultural practices are the single greatest threat to the Great Barrier Reef Marine Park.

High-resolution Imagery of Piston Cores - Caswell Sub-basin, Browse Basin Marine Survey (GA0345/GA0346/TAN1411)

Geoscience Australia (GA) conducted a marine survey (GA0345/GA0346/TAN1411) of the north-eastern Browse Basin (Caswell Sub-basin) between 9 October and 9 November 2014 to acquire seabed and shallow geological information to support an assessment of the CO2 storage potential of the basin. The survey, undertaken as part of the Department of Industry and Science's National CO2 Infrastructure Plan (NCIP), aimed to identify and characterise indicators of natural hydrocarbon or fluid seepage that may indicate compromised seal integrity in the region. 
The survey was conducted in three legs aboard the New Zealand research vessel RV Tangaroa, and included scientists and technical staff from GA, the NZ National Institute of Water and Atmospheric Research Ltd. (NIWA) and Fugro Survey Pty Ltd. Shipboard data (survey ID GA0345) collected included multibeam sonar bathymetry and backscatter over 12 areas (A1, A2, A3, A4, A6b, A7, A8, B1, C1, C2b, F1, M1) totalling 455 km2 in water depths ranging from 90 - 430 m, and 611 km of sub-bottom profile lines. Seabed samples were collected from 48 stations and included 99 Smith-McIntyre grabs and 41 piston cores. An Autonomous Underwater Vehicle (AUV) (survey ID GA0346) collected higher-resolution multibeam sonar bathymetry and backscatter data, totalling 7.7 km2, along with 71 line km of side scan sonar, underwater camera and sub-bottom profile data. Twenty two Remotely Operated Vehicle (ROV) missions collected 31 hours of underwater video, 657 still images, eight grabs and one core.
This catalogue entry refers to high-resolution imagery taken of piston cores. A total of 20 piston cores collected in water depths between 154-445 m on the continental shelf, were imaged using the Geotek GEOSCAN IV line scan camera. Each core section was imaged at 200 lines per cm, corresponding to a 50 micron pixel size, to produce a single JPG image for each section. For more information on how the piston cores were collected please refer to the post-survey report (follow link at right), or for more information on the MSCL-S please refer to the manual, (follow link at right).

Logistics report for borehole conductivity logging in the Frome AEM survey area, South Australia, 2010

Borehole induction conductivity data, commonly referred to as conductivity logs, were acquired from 20 boreholes in the Frome region of South Australia, during July-August 2010, in support of the Frome airborne electromagnetic (AEM) survey managed by Geoscience Australia (GA). The conductivity logs were used to assist in generating reference models for geophysical inversions of the AEM data, and to provide an independent dataset for assessing the inversion results.
The Frome AEM survey was acquired using the Fugro Airborne Surveys (FAS) TEMPEST fixed wing time-domain electromagnetic (TEM) AEM system. The acquisition and processing of data were carried out by FAS under contract to GA. The geophysical investigations were designed to deliver reliable, pre-competitive AEM data and scientific analysis of the energy resource potential of the Frome region of South Australia, including the flanks of the Northern Flinders Ranges, the Frome Embayment, the Olary Ranges and the northwestern Murray Basin. The Frome AEM survey covers a total area of 95,000 km2 and was flown between 22 May and 2 November 2010.
