MISO - Real-time aerosol chemistry measurements (ToF-ACSM) from the RV Investigator voyage IN2024_V01

This dataset presents the composition of non-refractory aerosols, including nitrate, ammonium, sulfate, organics, chloride, and sea salt, measured using a Time-of-Flight Aerosol Chemical Speciation Monitor (ToF-ACSM) during the IN2024_V01 voyage. The voyage, titled "Multidisciplinary Investigations of the Southern Ocean (MISO): Linking Physics, Biogeochemistry, Plankton, Aerosols, Clouds, and Climate," was conducted in the Southern Ocean and focused on understanding the interactions between physical, biological, and chemical processes in this critical region. The voyage took place from 2 January to 5 March 2024 (AEST), departing Hobart and returning to Fremantle. The data captured by the ToF-ACSM provide high-resolution, real-time measurements of aerosol species, contributing to the broader understanding of aerosol composition and its role in climate dynamics, ocean-atmosphere interactions, and biogeochemical cycles in the Southern Ocean. This dataset serves as a valuable resource for advancing research on atmospheric chemistry, aerosol-cloud interactions, and their implications for climate modelling and environmental policy.

Videos from Jervis Bay surveys

Several surveys to Jervis Bay, NSW were conducted between 2008 and 2009 to trial newly acquired Multibeam and video equipment, and to collect bathymetry and backscatter data, and characterise the benthic habitats and biota of Jervis Bay. During this time, two video surveys were conducted during the 17-20th June 2008 (GA survey #0312) and 25-26th August 2008 (GA survey #0309) in the south-eastern corner of Jervis Bay, NSW (off Darling Road) in water depths of 5-30 m.  Video transects were run alongshore (4 x 6 km transects) and offshore (6 x 3 km transects) to map the spatial distributions of benthic habitats and biota. Video footage was recorded to mini DV tapes, and copied to digital format.  For further information on this survey please refer to the post-survey report (GA Record 2009/10 - Geocat #68383).  In addition, a drop-camera survey was conducted during 23 - 26 November 2009 to collect still colour photographs on the seabed at 24 stations throughout Jervis Bay (bounding coordinates 35.0045Â°S, 150.6884Â°E to -35.1262Â°S, 150.7868Â°E.

Overview of GA/JAMSTEC collaboration for deep stratigraphic drilling on the Lord Howe Rise

Zealandia is an intriguing continental fragment submerged beneath the oceans between eastern Australia, New Zealand and New Caledonia. Deep, sediment-filled basins were formed as tectonic forces stretched Zealandia before it ultimately fractured and separated from Australia. 
Geoscience Australia and the Japan Agency of Marine Earth Science and Technology have been collaborating since 2014 with the goal to collect deep rock cores from a northern Zealandia basin. Analysis of these rock cores will unlock a 100-million-year history of geology, tectonics, past climate, and even ancient microbial life.
A proposal for scientific drilling to several kilometres below the seafloor - the first of its kind in Australia’s maritime jurisdiction - has been approved by the International Ocean Discovery Program, one of the world’s longest running and most successful scientific collaborations. If this innovative scientific drilling is funded, it will open up many new opportunities for Australian, Japanese and international researchers to study Earth processes, climate dynamics, and the limits of life on Earth.

Darwin Harbour Habitat Mapping Program: Predicted seabed gravel content

This resource contains a predicted seabed gravel content 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 seabed gravel content 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 a previous survey GA0333 collected by GA, AIMS and NTG-DENR. This dataset provides spatially continuous predictions of seabed %gravel (&gt;2000 µm) content for the Darwin and Bynoe harbour region, northern Australian marine margin. Data are presented in 10 m resolution raster grids format and ascii text file. Predictions are based on 395 samples and 14 environmental variables derived from high resolution multibeam sonar bathymetry and backscatter data. Accuracy of predictions is high, with a VEcv = 59% for gravel; and the predictive accuracy has been increased by 68.4% for gravel in comparison with the commonly used method (i.e., IDW).  Absences in predictions occur in this dataset as a result of non-availability associated with predictive variables. This dataset supersedes previous predictions of mud content for the Darwin and Bynoe harbour region with demonstrated improvements in predictive accuracy.

MODIS Derived Sea Surface Temperature dataset: Seasonal Means

The dataset measures the long-term seasonal means of the sea surface temperature (SST) of ocean surface waters. They are derived from MODIS (aqua) images using NASA's SeaDAS image processing software. The monthly SST images between July 2002 and December 2017 are used to calculate the means of the four austral seasons: winter (June, July, and August), spring (September, October and November), summer (December, January and February) and autumn (March, April and May). The extent of the dataset covers the entire Australian EEZ and surrounding waters (including the southern ocean). The unit of the dataset is Celsius degree.

This research is supported by the National Environmental Science Program (NESP) Marine Biodiversity Hub through Project D1.

Seabed environments and shallow geology of the Leveque Shelf, Browse Basin, Western Australia: seabed sediment laser measured grainsize data

In May 2013, Geoscience Australia, in collaboration with the Australian Institute of Marine Science, undertook a marine survey of the Leveque Shelf (survey number SOL5754/GA0340), a sub-basin of the Browse Basin. This survey provides seabed and shallow geological information to support an assessment of the CO2 storage potential of the Browse sedimentary basin. The basin, located on the Northwest Shelf, Western Australia, was previously identified by the Carbon Storage Taskforce (2009) as potentially suitable for CO2 storage. The survey was undertaken under the Australian Government's National CO2 Infrastructure Plan (NCIP) to help identify sites suitable for the long term storage of CO2 within reasonable distances of major sources of CO2 emissions. The principal aim of the Leveque Shelf marine survey was to look for evidence of any past or current gas or fluid seepage at the seabed, and to determine whether these features are related to structures (e.g. faults) in the Leveque Shelf area that may extend to the seabed. The survey also mapped seabed habitats and biota to provide information on communities and biophysical features that may be associated with seepage. This research, combined with deeper geological studies undertaken concurrently, addresses key questions on the potential for containment of CO2 in the basin's proposed CO2 storage unit, i.e. the basal sedimentary section (Late Jurassic and Early Cretaceous), and the regional integrity of the Heyward Formation (the seal unit overlying the main reservoir). The survey collected one hundred and eleven seabed sediment samples that were analysed for their grain size, textural composition and carbonate content. This dataset includes the results of grain size analysis measured by laser diffractometer.

Argo Float Data from RV Investigator voyages

Argo is a global partnership that gathers high-quality measurements of temperature and salinity from the upper 2000 meters of the ice-free oceans, along with data on mid-depth currents. This information is collected by more than 3,000 battery-powered autonomous floats that drift at depth across most of the world’s oceans. Approximately every 10 days, each float ascends to the surface over a period of about six hours, recording temperature and salinity as it rises. Upon reaching the surface, satellites determine the float’s position and receive the transmitted data. The float then adjusts its buoyancy to return to its original depth and continues drifting until the next cycle. Each float is designed to complete around 150 such cycles.

Argo Australia contributes to this effort by maintaining an array of profiling floats that provide real-time observations of the oceans surrounding Australia. Information and data from both Argo Australia and the International Argo program are available on the Argo Australia website (see data link below). CMAR maintains an internally accessible mirror of the US Argo server data, which is updated regularly (see data link below).

The hydrogeochemistry of groundwater in fractured bedrock aquifers beneath dryland salinity occurrences at Yass, NSW

Fresh to brackish groundwaters in the range of 250 to 2250 mglL occur in fractured bedrock aquifers beneath dryland salinity sites at Yass in the Southern Tablelands of New South Wales. The fractured bedrock in these catchments comprises marine, early Paleozoic slates, shales and sandstones in Dicks Creek and Williams Creek catchments, and porphyritic dacite and rhyodacite in Spring Creek catchment. The groundwaters are known to originate from recent meteoric waters. The waters represent various hydrochemical types, generated by chemical processes through water-rock interactions along their flow paths.  The present chemical composition of major cations and anions in groundwaters from these catchments is derived from the following processes: 1. water-rock interaction in recharge zones where dissolution of minerals and oxidation processes occur, 2. ion-exchange and reverse ion exchange reactions with clay where it is present in fractures and veins in the bedrock, and 3. microbially mediated reactions with organic matter which produce very low redox potentials.

BRUVS (TM) - Fish and Benthic survey of Southern Melville Bay 2007-10-29 to 2007-11-10

The dataset comprises 369 individuals from 39 species of fishes, sharks, rays and sea snakes observed at around Southern Melville Bay using 25 baited remote underwater video stations (BRUVS(TM)). 50 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.

Perth Basin hydrogeological inventory

This Perth Basin dataset contains descriptive attribute information for the areas bounded by the relevant spatial groundwater feature in the associated Hydrogeology Index map. Descriptive topics are grouped into the following themes: Location and administration; Demographics; Physical geography; Surface water; Geology; Hydrogeology; Groundwater; Groundwater management and use; Environment; Land use and industry types; and Scientific stimulus.

The Perth Basin is a complex geological region extending along Australia's southwest margin for about 1,300 km. It comprises sub-basins, troughs, terraces, and shelves, hosting sedimentary rocks with coal, oil, gas, and significant groundwater resources. Off the coast of Western Australia, it reaches depths of up to 4,500 m, while its onshore part extends up to 90 km inland. The basin is bounded by the Yilgarn Craton to the east, and the Carnarvon and Bremer basins to the north and south.

The basin's history involves two main rifting phases in the Permian and Late Jurassic to Early Cretaceous, creating 15 sub-basins with varying sedimentary thickness due to compartmentalization and fault reactivation. The sedimentary succession mainly comprises fluviatile Permian to Early Cretaceous rocks over Archean and Proterozoic basement blocks. Differences exist between northern and southern sequences, with the south being continental and the north featuring marine deposits.

During the Permian, faulting and clastic sedimentation dominated, with marine transgressions in the north and continental rocks in the south. The Triassic saw a similar pattern, with the southern succession being continental and the northern succession showing marine deposits. The Kockatea Shale became a primary hydrocarbon source. The Jurassic period witnessed marine incursions in the central basin, while the Late Jurassic experienced sea level regression and deposition of the Yarragadee Formation. The Cretaceous saw the formation of the Early Cretaceous Parmelia Group due to heavy tectonic activity. The southern basin had a marine transgression leading to the Warnbro Group's deposition with valuable groundwater resources. Post-Cretaceous, Cenozoic deposits covered the basin with varying thicknesses.

Overall, the Perth Basin's geological history reveals a diverse sedimentary record with economic and resource significance.

Distribution and biomass of Antarctic krill (Euphausia superba) in the eastern sector of the CCAMLR Division 58.4.2 (55°E to 80°E), Antarctica, RV Investigator voyage IN2021_V01

This dataset was collected during the 2021 TEMPO voyage in the East Antarctic sector of the Southern Ocean as part of the Marine National Facility RV Investigator research voyage IN2021_V01. The voyage took place from Hobart (TAS) to Hobart between 29 January and 24 March 2021 (AEST) under the TEMPO (Trends in Euphausiids off Mawson, Predators, and Oceanography) program. Acoustic data collected along transects between 55°E and 80°E were analysed using CCAMLR standard protocols (SC-CAMLR, 2000) to identify Antarctic krill (Euphausia superba) echoes and estimate krill areal biomass density.

Observations were obtained using a calibrated EK80 scientific echosounder operating continuously at 120 kHz in cold-water conditions. Krill biomass estimates were complemented by biological sampling using a Rectangular Midwater Trawl (RMT 1+8), providing measurements of krill total length and wet mass.

The dataset describes the spatial distribution and biomass density of Antarctic krill across the eastern sector of CCAMLR Division 58.4.2. Supporting data are provided in CSV format and are organised by instrument type, enabling integration of acoustic and net sampling observations for further analysis.

Sedimentology and Geomorphology of the East Marine Region: A Spatial Analysis

This report presents the geomorphology and sedimentology of the East Marine Region. The
three main outputs of the report include: 1) a review of previous geological research undertaken in
the East Marine Region (EMR); 2) the results of a quantitative study of seabed sediment texture and
composition for these regions; and 3) a synthesis of this information characterizing regional trends in
sedimentology, geomorphology and bathymetry. The study is a collaboration between Geoscience
Australia and the Department of the Environment, Water, Heritage and the Arts (DEWHA) and is a
continuation of similar work conducted for the North West Marine Region (Potter et al., in press;
Baker et al., 2008) and the South West Marine Region (Richardson et al., 2005). By combining results
of previous qualitative work and quantitative information generated from existing and new data, this
report provides an improved understanding of sedimentology for the EMR. Information contained
within this report will contribute to the Department of the Environment, Water, Heritage and the Arts
national work program and will also assist in the marine bioregional planning for the East Marine
Region.

Previous sediment studies in the EMR have predominantly produced qualitative results at local scales.
Geomorphic, sedimentary and biological information has previously been utilised to develop a
National Bioregionalisation of Australia's Exclusive Economic Zone (EEZ) (Department of the
Environment and Heritage (National Oceans Office), 2005; now the Department of the Environment,
Water, Heritage and the Arts) and substantive geomorphic features of the eastern continental margins
have already been identified and mapped (Heap and Harris, in press). This report adds
significantly to these previous studies by incorporating the information in a sedimentological
synthesis that includes a discussion of the implications for marine conservation in the EMR.
The physical characteristics of the seabed in the EMR, as described by the sediment texture and
composition data, can assist in determining the diversity of benthic marine habitats in the EMR. These
data represent enduring features which are elements of the physical environment that do not change
considerably and they are known to influence the diversity of biological systems. This is important
for marine conservation by contributing to the better definition and characterisation of benthic
habitats. Seabed texture and composition are easily measurable parameters that when combined with
other physical features can be used to create "seascapes" that serve as broad surrogates for benthic
habitats and biota (Whiteway et al., 2007). Seascapes have the potential to be used in informing the
marine bioregional planning process.
