Jervis Bay Infaunal species level data

Geoscience Australia carried out marine surveys in Jervis Bay (NSW) in 2007, 2008 and 2009 (GA303, GA305, GA309, GA312) to map seabed bathymetry and characterise benthic environments through co-located sampling of surface sediments (for textural and biogeochemical analysis) and infauna, observation of benthic habitats using underwater towed video and stills photography, and measurement of ocean tides and wave-generated currents. Data and samples were acquired using the Defence Science and Technology Organisation (DSTO) Research Vessel Kimbla. Bathymetric mapping, sampling and tide/wave measurement were concentrated in a 3x5 km survey grid (named Darling Road Grid, DRG) within the southern part of the Jervis Bay, incorporating the bay entrance. Additional sampling and stills photography plus bathymetric mapping along transits was undertaken at representative habitat types outside the DRG.

Redmap (Tasmania) - Sightings of Reptilian Species

Redmap is a primarily a website that invites the community to spot, log and map marine species that are uncommon in their region, or along particular parts of their coast. The information collected is mapped and displayed on the site, demonstrating, in time, how species distributions may be changing.

Sightings are divided into two categories – those with a photo that can be ‘verified’ by a marine biologist, and sightings without photos that we call community sightings (anecdotal). All the information collected, with and without photos, is mapped and will be used in the following years to map out a ‘story’ of changes occurring in our marine environment.

The main data collected includes the species sighted (normally selected from a list comprising preselected species of interest), the location, date/time and activity being undertaken.  Other optional information gathered include biological data such as sex, size and weight and environmental data such as water depth and temperature and habitat.

This record is associated with live data (and will subsequently change over time) and spatial elements have reduced accuracy.  It is also subject to a three year embargo (ie. does not contain data less than three years old).  If you wish to discuss obtaining a citable, static dataset, that is current and/or contains accurate spatial elements, please see Point of Contact.

Mapping and classification of Darwin Harbour seabed

This data presents the results of seabed mapping and habitat classification surveys completed in Darwin Harbour during 2011 and 2013 as part of the Northern Territory Government's marine habitat mapping program. This research is a collaboration between Geoscience Australia (GA), the Australian Institute of Marine Science (AIMS), the Department of Land Resource Management (DLRM) and the Darwin Port Corporation. Key objectives are to:
- Produce detailed maps of the bathymetry and derived parameters such as slope and rugosity,
- Classify the seabed into areas of hard and soft substrate, and,
- Produce seabed habitat maps (or seascapes).

Key outcomes from the surveys include:
1. Improved understanding of the seabed of Darwin Harbour. The main seabed geomorphic features identified in Darwin Harbour include banks, ridges, plains and scarps, and a deep central channel that divides into smaller and shallower channels. Acoustically hard substrates are found mostly on banks and are associated with rocky reef and sponge gardens, and are often overlain by a thin veneer of sandy sediment. In contrast, plains and channels are characterised by acoustically soft substrates and are associated with fine sediments (mud and sand).
2. Classification of physical seabed properties to produce a Seascape Map for Darwin Harbour. Six seascape classes (potential habitats) were derived using an Iterative Self Organising (ISO) unsupervised classification scheme. These six classes are related to statistically unique combinations of seabed substrate, relief, bedform and presence of sediment veneer (quite often inferred from presence of epibenthic biota).

IMOS - Coastal Wave Buoys Facility

The national IMOS Coastal Wave Buoys Facility provides data essential for understanding the processes and changes driven by waves and temperature in coastal zones. The moored wave buoys will deliver near-real-time wave and temperature observations around the Australian coast. The data will be used in the development and improvement of models used to predict and forecast hazards which threaten coastal populations, and to understand the impacts of environmental disturbances (such as extreme storm events and marine heat waves) on coastal ecosystems.

The facility platform is the ‘Spotter’, a small format (0.42m diameter) Global Navigation Satellite System (GNSS) wave buoy manufactured by Sofar Ocean Technologies. 

The facility is based at the University of Western Australia (UWA) and the regional buoy management are led by: Deakin University (VIC); the South Australian Research and Development Institute (SARDI) and Flinders University in South Australia (SA); the New South Wales Department of Climate Change, Energy, the Environment and Water (DCEEW) - Water Wetlands and Coastal Science Branch, the University of Newcastle and the Sydney Institute of Marine Science, in New South Wales (NSW); the Australian Institute of Marine Science (AIMS) in the Northern Territory (NT); AIMS and the Queensland Department of Science and Innovation in Queensland (QLD); and UWA in Western Australia (WA).

The facility currently consists of 60 sites – 23 National (IMOS-supported) and 37 regional co-invest. Sites span 10m-70m depth around Australia. 

Core variables measured by the facility include integrated (e.g., wave height, wave period, wave direction) and spectral (e.g., 1D energy density) wave parameters as well as sea surface temperature.

The data from these buoys will be available in in real time (https://imos.aodn.org.au/imos123/home?uuid=b299cdcd-3dee-48aa-abdd-e0fcdbb9cadc) and delayed mode as part of the National Wave Archive (https://portal.aodn.org.au/search?uuid=2807f3aa-4db0-4924-b64b-354ae8c10b58), as well as via AusWaves.

Explanatory notes, Brighton Downs Sheet, Queensland (BMR Explan Notes and map)

A reconnaissance survey of the Brighton Downs 4-mile Sheet area was conducted by geologists R. R. Vine and W. Jauncey of the Bureau of Mineral Resources between June and August, 1961. Cretaceous rocks crop out over nearly the whole of the Brighton Downs Sheet area. Lower Cretaceous marine sediments appear in the north-west and dip gently eastwards below freshwater deposits of Lower to Upper Cretaceous age. In two main areas of Tertiary sedimentation, one in the north and the other in the south-west, sandstone, clay and limestone have been deposited. Lateritisation is widespread over the area.

The Arrinthrunga Formation: Upper Cambrian epeiric carbonates in the Georgina Basin, central Australia

The Arrinthrunga Formation (Upper Cambrian) in the Georgina Basin, central Australia, is a complex carbonate and mixed carbonate-siliciclastic sequence deposited in an extensive and intermittently emergent epeiric sea. It accumulated on a low-relief substratum in very shallow water with restricted tidal movements; these factors and a warm arid climate contributed to high salinities and the local precipitation of evaporites. Filamentous algae proliferated in the warm hypersaline shallow waters, in which grazing organisms were virtually absent, and exerted a major control on the type and distribution of carbonate lithologies. At the close of the Middle Cambrian a peloid shoal or barrier bar prograded across a broad region of shallow-marine tidal carbonates, bordered in the west by intermittently emergent algal flats. A hypersaline lagoon developed in the lee of the shoal, and a thick sequence of algal-derived peloid lime-muds was deposited. Shoaling sedimentation and intermittent emergence favoured the establishment of gypsiferous algal mats in the northwest, and, with increasing emergence, laminated algal mats colonised much of the area. A transgression of the sea then flushed the stagnant waters, and a reticulate maze of algal bioherms and interbiohermal peloid-ooid sands was established across the whole of the depositional area. Under the influence of shoaling sedimentation and a stable sea level, nearshore environments migrated laterally, and quartz-ooid shoals, intermittently emergent algal mats, and terrigenous sands prograded across the western and central portion of the sea. The progressive shallowing led to local emergence, reduced circulation, and stagnation, so that sections of the sea became isolated and halite evaporite pans were formed. A second transgression of the sea again favoured the widespread growth of algal bioherms, and prograding ooid shoals then spread out across all but the eastern portion of the depositional area. Sedimentation ended as the sea regressed, and a karst erosion surface formed on the emergent landmass.

Seafloor imagery from the Totten seafloor, East Antarctica from NPB14-02

Research was conducted aboard the RVIB Nathaniel B Palmer during NBP14-02 (29 January – 16 March 2014) across a &gt;3000 km2 area. A ‘yoyo’ camera, with downward facing digital still and video cameras mounted within a tubular steel frame, was deployed on a coaxial cable to image the seafloor. Still images have been analysed for seafloor habitats. 

The Ocean Imaging Systems DSC 10000 digital still camera (10.2 megapixel, 20 mm, Nikon D-80 Camera) was contained within a titanium housing. Camera settings were: F-8, Focus 1.9 m, ASA-400. An Ocean Imaging Systems 3831 Strobe (200 W-S) was positioned 1 m from the camera at an angle of 26o from vertical. A Model 494 Bottom Contact Switch triggered the camera and strobe at 2.5 m above the seafloor, imaging ~ 4.8 m2 of seafloor.

Imagery can be viewed and downloaded from the National Computing Infrastructure (NCI) data catalogue THREDDS: https://thredds.nci.org.au/thredds/catalog/fk1/NBP14_02_Sabrina_Shelf/catalog.html

Characterization of uranium redox state in organic-rich marine sediments of the Cretaceous Toolebuc Formation, Australia

Throughout geological history, marine organic-rich shales show variable but appreciable enrichment in uranium (U), &lt; 5 to &gt; 500 ppm. Here we report the results of high-energy resolution fluorescence detection (HERFD) x-ray absorption spectroscopy at U L3 and M4 edges to characterize U speciation in marine sediments.



We characterised U oxidation state in samples from the Cretaceous Toolebuc Formation of the Eromanga Basin, Australia. Nine samples were carbonaceous shales with high total organic carbon (TOC) content of 5.9 to 13.4 wt&nbsp;% and with low maturity organic matter. Two samples of coquinite were selected for comparison (TOC 0.3 and 2.4 wt %).



Our results suggest that a significant proportion of U in marine black shales (~20 to 30%) exists as U(VI) (Figures 1-2), despite the extremely reducing (anoxic to euxinic) conditions during sediment precipitation and diagenesis. Within individual samples, spot analyses indicate variation in the estimated oxidation state within a range of ~20% of U(VI). Uranium is unevenly distributed at mm to nanoscale. Nanoscale secondary ion mass spectrometry (NanoSIMS) reveals different associations that often coexist in single samples; nano-particulate uranium is associated with organic matter matrix or sulphide minerals, whereas phosphate minerals display diffuse uranium enrichment. The coquinite has a higher proportion of U(VI), consistent with the dysoxic depositional environment (Boreham and Powell, 1987).



The unexpectedly enhanced proportion of U(VI) relative to U(IV) within marine organic-rich shales implies that U might not be immediately fixed by reduction processes during sedimentation, but adsorbed by accumulating organic matter, at least in part as U(VI). This is consistent with the behaviour of uranium reported within the water column of the anoxic Black Sea (Anderson, 1989), experiments on U(VI) sorption by organic matter (e.g., Bhat et al., 2008), and previously documented redox state of U from continental organic-rich Eocene (56-34 Ma) sediments of paleochannel and lacustrine origin (Cumberland et al., 2018).



The results are significant for improving hydrocarbon exploration in known fields (covering the gap to a carbon-free economy without development of new greenfield oil provinces); economic geology (uranium, base-metal, and critical-metal deposits); and environmental management (evaluating potential mobilization of U by groundwaters).
