SA Detailed Gravity Survey 96A2 (P199656), 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 SA Detailed Gravity Survey 96A2 (P199656) contains a total of 7023 point data values acquired at a spacing between 100 and 2000 metres. The data is located in SA and were acquired in 1996, under project No. 199656 for South Australian Steel and Energy Pty Ltd.

Curnamona 20m cell total count 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 Curnamona 20m cell total count grid geodetic has a cell size of 0.00021 degrees (approximately 21m) and shows the terrestrial dose rate of the Curnamona, SA, Broken Hill Exploration Initiative, 1995. The data used to produce this grid was acquired in 1995 by the SA Government, and consisted of 62542 line-kilometres of data at a line spacing between 100m and 400m, and 60m terrain clearance.

Conodonts from the Lower Ordovician Coolibah Formation, Georgina Basin, central Australia

The Coolibah Formation outcropping around the Toko Syncline, southeastern Georgina Basin, was sampled for conodonts during a multidisciplinary study of Georgina Basin geology by the Australian Geological Survey  organisation. Twenty-two species of conodonts belonging to 17 genera recovered from acid insoluble residues are described. Alcoorina and Tokoconus are new genera; Alcoorina nadala, Bergstroemognathus kirki and Tokoconus wheelamanensis are previously undescribed species. Four species remain in open nomenclature awaiting more material. The conodont faunas are grouped into three broad biostratigraphic associations, although few sections record all three. Faunas low in the Coolibah Formation are dominated by Drepanoistodus costatus (Abaimova) and Scolopodus multicostatus Barnes and Tuke, with Diaphorodus tortus (McTavish), Scandodus sp. nov. A and hyaline conical elements. The succeeding conodont association records first appearances of Ansella fengxiangensis (An and others).  Aurilobodus? leptosomatus An. Paroistodus originalis (Sergeeva). Protoprioniodus nyinti Cooper. and Triangulodus larapintinensis (Crespin).  Specimens of younger species are found in the uppermost Coolibah Formation.  Examination of these associations within different sections indicates that both upper and lower contacts of the Coolibah Formation are probably diachronous.  Recovered conodonts are closest in affinity to those of North China, and North and South Korea.  They range in age from middle to late Arenig.

AUSGeoid98 v.1.0 data files:  (sc56-16)

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.

Post-survey report: CANYONS - Cape Darnley paleoceanography from sediment cores IN2023_V01

The CANYONS voyage on R/V Investigator aimed to investigate past and present processes governing the flow pathways, formation and geochemical signatures of Antarctic Bottom Water (AABW) off Cape Darnley, East Antarctica. The proposed survey area was focussed on the Wild and Daly canyons and the adjacent sediment drifts - the Daly and ‘Armand’ drifts. The survey aimed to collect systematic multibeam bathymetry and sub-bottom profiles across the region to support collection of long sediment cores (up to 24 m), kasten cores and multicores, CTDs and deep towed camera transects.
Due to a medical evacuation 5 days after arriving in the survey area we were only able to partially map the northern part of Wild Canyon and the ‘Armand’ Drift, collect 1 piston core (15.2 m), 2 kasten cores and 2 CTDs. Some seafloor images were also obtained from a camera system mounted to the CTD frame. Sediment cores were sampled for physical properties, microfossil content, biostratigraphic markers, ancient DNA and various geochemical signatures. Water samples from the CTDs were collected for hydrochemistry, biogeochemistry and environmental DNA. Analysis of these datasets is currently underway and forms part of several PhD projects.
Underway water samples were collected during transit and within the survey area for hydrochemistry, biogeochemistry and environmental DNA (eDNA). In addition, a magnetometer was towed on the southward transit and a continuous plankton recorder on the northward transit. Aerosols were sampled throughout the survey for trace elements and bio-aerosols. Several Argo floats, including 2 biogeochemical Argo floats were deployed during the transit and in the survey area.
We undertook two days of opportunistic science within Two Peoples Canyon offshore Albany following the medical evacuation. This work focussed on characterising the seafloor biota of this poorly known region by undertaking 2 deep tow camera transects and 1 biological dredge. We also collected 3 CTDs and 1 kasten core to understand the modern and past oceanography in the context of previous work in the region.
Outreach was conducted throughout the voyage by our Sea2School program to Primary and High school students across Australia and internationally. We undertook public outreach via regular blogs, podcasts, posts to our CANYONS Twitter, Facebook and Instagram accounts and through media interviews.
Many of the science team were early career researchers and post-graduate students. They gained not only first-hand experience and skills in undertaking marine science at sea, but also in responding and adapting to rapidly changing situations with grace and resilience.

Geological Framework of the Southern Lord Howe Rise/West Norfolk Ridge Region : Project 121.30 : Post Cruise Report

Project 121.30 - "Lord Howe Rise and Norfolk Ridge 'Law of Sea' Study" -was initiatedto improve our understanding of the geological framework of the southern part of theLord Howe Rise region, in the vicinity of the Australia/New Zealand seabed boundary zone.
The major objectives of the project are:
To investigate the structure, stratigraphy and basin development of the southern LordHowe Rise, southern New Caledonia Basin and the West Norfolk Ridge.
To assess the resource potential of the major structural features within the region.
To determine the tectonic framework, crustal characteristics and evolution of the region, and attempt to understand the processes that have produced narrow strips of thinned and extended continental lithosphere ("ribbon continents") separated bynarrow ocean basins.
To acquire data to assist with the definition of Australia's 'legal' Continental Shelf on the southwestern margin of the Lord Howe Rise.
Because of the presence of Lord Howe Island and Norfolk Island, Australia has laid claim to a large part of the seabed in the region, enveloped by a 200 nautical mile Exclusive Economic Zone (EEZ) around each island, plus areas of 'legal' ContinentalShelf beyond the EEZ. The total area of Australia's 'legal' Continental Shelf in the Lord Howe Rise region would be about 1.65 million km2. While the seabed boundary in the northern part of the region has been negotiated between Australia and France, there is not, as yet, a negotiated boundary between Australia and New Zealand in the southernLord Howe Rise/West Norfolk Ridge region.
The proposal for Survey 114 was to acquire approximately 3250 km of multichannelseismic and associated geophysical data. The data was acquired mainly on longregional lines, two of which extended from the Tasman Basin to the Norfolk Basin, using a 3000 m streamer (120 x 25 m groups), 49 litre sleeve gun arrays, 16 secondrecords, and 30-fold coverage.
The ship departed Sydney at 2000 hrs on Friday, 6 November 1992, and, after transitingthrough rough seas, arrived in the study area on the evening of 9 November. The cablewas deployed and balanced by midnight, 10 November. The next twenty one days wasspent shooting deep crustal (16 sec.) seismic . During this period a total of 3191 km ofseismic was shot, over 70% with two gun arrays operating. This was achieved in spiteof 3.5 days loss as a result of bad weather and 20 hours loss for cable repairs as a resultof fish bites. Seismic acquisition ceased on the afternoon of 1 December. The shipreturned to Sydney at 1730 hrs on Thursday, 3 December.
Overall, the quality of the seismic data was very good. When shooting the two verylong lines, the weather remained reasonably calm, and so noise levels were withinspecifications.
