Strontium, carbon and oxygen isotope data from NDI Carrara 1

NDI Carrara&nbsp;1 is a 1751 m stratigraphic drill hole completed in 2020 as part of the MinEx CRC National Drilling Initiative (NDI). This campaign was a collaboration between Geoscience Australia under the Exploring for the Future program, together with MinEx CRC and the Northern Territory Geological Survey. It is the first drillhole to intersect Proterozoic rocks of the Carrara Sub-basin, a recently discovered depocentre in the South Nicholson region. The drill hole intersected ~625 m of the Paleozoic Georgina Basin, which overlies ~1120 m of Proterozoic carbonates, black shales and siliciclastic rocks, with hydrocarbon shows encountered in both the Paleozoic and Proterozoic sections. Following the completion of the drillhole, a comprehensive analytical program was carried out by Geoscience Australia to better understand the geology of the Carrara Sub-basin and its resource potential.



Here we present new high-resolution strontium (87Sr/86Sr), carbon (δ13C) and oxygen (δ18O) isotope data from carbonate bearing samples of the Paleozoic Georgina Basin and the Proterozoic Lawn Hill Formation intersected in NDI Carrara&nbsp;1. The aim of this data acquisition was to provide an improved understanding of the paleo-depositional environments and local/global chemostratigraphy trends recorded in the Carrara Sub-basin. 



The majority of samples show significant alteration and thus caution should be exercised when using this data for assessing primary depositional conditions and contemporary sea-water chemistry. Despite the altered nature of most samples, samples belonging to undifferentiated Georgina Basin preserve 87Sr/86Sr ratios close to that of mid-Cambrian seawater, indicating the sampled intervals of Georgina Basin were likely connected to the global Cambrian ocean.&nbsp;Two small positive δ13C excursions (with positive shift in δ18O) within Georgina Basin samples may coincide with reported mid-Cambrian positive δ13C global marine excursions. 



The least altered samples from the Proterozoic Lawn Hill Formation show more radiogenic 87Sr/86Sr values than the expected value of coeval mid-Proterozoic ocean at ~1600 Ma. These radiogenic 87Sr/86Sr values may reflect (i) influx of terrigenous material into a restricted basin with reduced interaction with the global ocean, or (ii) secondary overprinting by more radiogenic diagenetic fluids.

Gravity provinces and their nomenclature

Gravity features have been defined and named by the various authors who have interpreted the results of land and marine reconnaissance gravity surveys in Australia. In general, two classes of feature have been identified - gravity provinces and gravity units. A gravity province is a region where the gravity field is characterized by uniformity of some property, such as contour trend, gravity level, or degree of contour disturbance, which distinguishes it from neighbouring provinces. A gravity unit is a subdivision of a province. Neighbouring units are again distinguished from each other by differences in contour trend, gravity level, or degree of contour disturbance - but on a smaller scale. Many gravity features were originally defined from the results of individual reconnaissance surveys in isolated areas and have been shown to be inconsistent with the regional gravity pattern after more extensive coverage has been obtained. Land and marine gravity coverage is now virtually complete, and an attempt has now been made to rationalize gravity province boundaries and names over the whole of Australia and its continental margins. In all, 125 provinces have been defined and named. It is recommended that authors make use of the names when discussing regional gravity features.

Biogeochemical Zones Within a Macrotidal, Dry-Tropical Fluvial-Marine Transition Area: A Dry-Season Perspective

The Fitzroy River delivers large amounts of nutrients and fine sediments to Keppel Bay (contiguous with the Great Barrier Reef Lagoon) during intermittent flow events. This study explores sources, forms and transformations of nutrients in Keppel Bay, and develops a functional process zonation that integrates seabed geochemistry and water column nutrient characteristics which are controlled by suspended sediment. The water column and seabed properties were investigated over two dry seasons, with supplementary core incubations taken to measure carbon decomposition rates and nutrient fluxes. Keppel Bay can be divided into three zones, the: zone of maximum resuspension (ZMR); coastal transitional zone (CTZ); and blue water zone (BWZ). Mineralisation of predominantly terrestrial organic matter occurs in the ZMR where nutrient uptake by phytoplankton is light limited. The CTZ and BWZ had higher light penetration and phytoplankton growth was likely limited by N and P, respectively. The identified zones conform to the bathymetry and hydrodynamic characteristics of the bay, allowing for the development of an integrated conceptual model accounting for the benthic and pelagic biogeochemical processes. Recognition of these different zones shows that considerable variation in benthic and water column properties is possible within a small system with the bathymetric and hydrodynamic characteristics of the fluidised bed reactor.

Australian Offshore Mineral Locations Map, August 2006

The Australian Offshore Mineral Locations map shows mineral occurrences and deposits within Australia's 200 nautical mile exclusive economic zone and extended continental shelf.

Australia will have one of the largest marine jurisdictions in the world (14.4 million square kilometres) if the United Nations Commission on the Limits of the Continental Shelf agrees to Australia's submission on the outer limit of its extended continental shelf. This is greater than Australia's total land area (13.6 million square kilometres), including Antarctica.

The Offshore Mineral Locations map sheds light on the mineral prospectivity in this exciting, but poorly known frontier. It should serve also to ensure mineral values are considered in marine planning and decision making.

The Australian Offshore Mineral Locations map draws together data from published and unpublished marine research surveys as well as reports from federal and state government records.

Mineral locations shown include manganese nodules and crusts, shellsand, construction aggregate, heavy mineral sand, phosphorites, diamonds, tin, copper, gold and coal.

Types of mineralisation, some interpreted from limited information, provide an insight into the nature of the depositional settings.

Bathymetry shows the variable physiography of the seafloor that surrounds Australia. For the first time it is possible to identify features such as the contextual setting of manganese crusts and nodules on the East Tasman Plateau and South Tasman Rise, and shellsand and cobalt crust on the edge of the Ceduna Terrace where it descends to the South Australian Abyssal Plain.

Insets and images on the map show further detail, mineral specimens and operational aspects associated with exploration and recovery of marine minerals.

The map is the result of a collaborative project between Geoscience Australia, CSIRO's Wealth from Oceans Flagship and Division of Exploration and Mining, and each of the State and Northern Territory Geological Surveys.

The Australian Offshore Mineral Locations data can be viewed online by using Geoscience Australia's Australian Marine Spatial Information System (AMSIS). AMSIS contains more than 80 layers of Australian marine information which can be viewed and integrated with mineral locations data to create maps to meet specific requirements.

Distribution, abundance and trail characteristics of acorn worms at Australian continental margins

Acorn worms (Enteropneusta), which were previously thought to be a missing link in understanding the evolution of chordates, are an unusual and potentially important component of many deep-sea benthic environments, particularly for nutrient cycling. However very little is known about their distribution, abundance, or behaviour in deep-sea environments around the world, and almost nothing is known about their distribution within Australian waters.  In this study, we take advantage of two large-scale deep-sea mapping surveys along the eastern and western continental margins of Australia to quantify the distribution, abundance and trail-forming behaviour of this highly unusual taxon.  This is the first study to quantify the abundance and trail behaviour of acorn worms within Australian waters and provides the first evidence of strong depth-related distributions.

RV Investigator Voyage IN2025_V02 CTD Data

This record describes the CTD data collected on Investigator voyage IN2025_V02, titled: "Multiyear: Integrated Marine Observing System (IMOS) Southern Ocean Time Series (SOTS) Strategic Partnership." The voyage took place between March 26, 2025 and April 14, 2025 (AEST), departing from Hobart and returning to Hobart.

Data for 6 CTD deployments were acquired using the Sea-Bird SBE911 CTD unit #22, fitted with 36 twelve-litre bottles on the rosette sampler. Calibration factors supplied by Sea-Bird and the CSIRO calibration lab were used to compute the pressures, preliminary conductivity values, and temperature data. The data were subjected to automated QC to remove spikes and out-of-range values.

The final conductivity calibration was based on a single deployment grouping. The final calibration from the primary sensor had a standard deviation (SD) of 0.001185 PSU, within our target of ‘better than 0.002 PSU’. The standard product of 1-decibar binned averages were produced using data from the primary sensors.

The dissolved oxygen data calibration fit had a SD of 0.64003 μM. The agreement between the CTD and bottle data was good.

Altimeter, PAR, CDOM, Transmissometer, Chlorophyll-a and Scattering sensors were also installed on the auxiliary A/D channels of the CTD.

The collected data were processed (quality-controlled), and subsequently archived by the CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre (IDC).

Additional information regarding this dataset may be contained in the Voyage Summary and the Data Processing Report.

Summary Of Data And Results Otway Basin, South Australia Mount Salt No. 1 Well Of Oil Development No Liability

Mount Salt No. 1 Well was located approximately twelve miles south-west of Mount Gambier in the South Australian part of the Otway Basin. The well was drilled by Reading and Bates (Australia) Pty Ltd for Oil Development No Liability, to a total depth of 10,044 feet. DrillIng commenced on 9th May, 1962 and was completed on 21st September, 1962. A full programme of logging, testing, and coring was undertaken.

After passing through about 3260 feet of Oligocene and Eocene-Palaeocene sediments, the well entered a thick sequence of Upper Cretaceous sands, siltstones and clays that persisted to total depth. The upper part of this section has been correlated with the (?) Paaratte Formation, and the well bottomed in either basal Upper Cretaceous or uppermost Lower Cretaceous marine or brackish strata that probably correlate with either the top of the Waarre Formation or the Flaxmans Beds of Flaxmans No. 1 Well. The base of the Upper Cretaceous is not clearly defined, and no definite conclusions as to the correlation of the section below the Knight Group (? 590 to? 3260 feet) have been advanced.

Mount Salt No. 1 Well was drilled to test the petroleum potential of Cretaceous sediments in a closed structure detected by photogeology and proved by a structure drilling programme. Traces of crude oil were detected by core analysis and a show of gas was recorded from the interval 9830 to 9848 feet. Five drillstem tests were attempted but only one, over the interval 9813 to 9892 feet, was successful, obtaining 4070 feet of highly saline water.

The stratigraphic drilling operation at Mount Salt No. 1 was subsidized under the Petroleum Search Subsidy Act 1959-1961, from 980 feet to total depth.

Physical Surrogates for Macrofaunal Distributions and Abundance in a Tropical Gulf

The characterisation of benthic habitats based on their abiotic (physical and chemical) attributes remains poorly defined in the marine environment, but is becoming increasingly central in the development of marine management plans in Australia and elsewhere in the world. The current study tested this link between physical and biological datasets for the southern Gulf of Carpentaria, Australia. The results presented were based on a range of physical factors, including the sediment composition (grain size and carbonate content), sediment mobility, water depth and organic carbon flux, and their relationship to the distribution and diversity of benthic macrofauna was tested. The results reveal the importance of process-based indices, such as sediment mobility, in addition to other environmental factors in defining the distribution of the benthic macrofauna. The distribution of the benthic macrofauna changes gradationally across the south-eastern Gulf, associated with changes in the per cent mud and gravel, the seabed exposure and the water depth. Patterns of diversity also reveal the importance of physical processes such as sediment mobility in defining benthic habitats. The species' environment relationships observed at the small scale of the current study are consistent with broader associations observed for other organisms within the Gulf.

Processes controlling the formation of the Mertz Drift, George Vth continental shelf, East Antarctica: evidence from 35 Khz sub-bottom profiling and sediment cores

Recently discovered drift deposits on the Antarctic continental shelf provide access to information on the Holocene palaeoceanography of the bottom current regime within deep shelf basins that were previously inaccessible. The George Vth Basin on the East Antarctic margin has been identified by oceanographers as an important source of Antarctic Bottom Water, hence the Holocene history of bottom current activity here may be relevant to variations in bottom water export.

Mapping the ocean floor

Have you ever wondered how we know the depth of the ocean? Sonar is the main technology used investigate the location of submarine canyons, seamounts, abyssal plains and if the seafloor is sand or rock. This activity builds understanding of sonar technique and applications through a) processing and plotting provided data to discover a seafloor feature or shipwreck, and b) bouncing balls on different surfaces and analysing rebound, relating this to ground hardness then extend understanding to ‘backscatter’ in bathymetry surveys. It is suitable for middle secondary students, but could be extended for senior students of Earth science, marine science/oceanography, and physics.

BRUVS (TM) - Fish and Benthic survey of Ashmore Reef and Rowleys Shoals 2004-10-18 to 2004-10-31

The dataset comprises 15643 individuals from 416 species of fishes, sharks, rays and sea snakes observed at around Ashmore Reef and Rowleys Shoals using 125 baited remote underwater video stations (BRUVS(TM)). 4533 images were captured from these cameras.

Approximately 3500 of the best images from all BRUVS (TM) projects are stored in a reference library.

Data recorded concern:
- classification of the habitat in the field of view (topography, sediments, benthos)
- the identity of fish and CAABCODES
- their time of arrival
- their behaviour (8 categories, including feeding on the bait)
- their maturity (adult or juvenile)
- their relative abundance (as MaxN = the maximum number visible at one time, or distinguishable at different times as separate individuals e.g. much larger/smaller, male/female)
- the time elapsed before MaxN and feeding occurs.

A custom interface has been developed by AIMS staff, using Microsoft Access, for reading and analysis of BRUVS(TM) tapes.
