Defining a chemostratigraphic framework for the Adavale Basin - Inorganic and stable isotopic analysis of 10 petroleum wells from the Adavale Basin, Queensland

As part of the Data Driven Discoveries program, Geoscience Australia and the Geological Survey of Queensland collaborated to re-examine legacy well cuttings for a chemostratigraphic study. The aim was to identify opportunities for resource discovery in the Devonian-aged Adavale Basin in south-central Queensland by conducting a chemostratigraphic study to define regional stratigraphic correlations in a structurally complex basin with limited well penetrations. A total of 1,489 cutting samples were analysed for whole-rock geochemistry, as well as subsets of samples for whole-rock mineralogy and/or carbonate carbon and oxygen isotopes, from a whole-rock sample. The purpose was to establish new chemostratigraphic correlations across the basin independently, using data from 10 wells that sampled the Adavale Basin.

Pore Water Geochemistry of Eastern Mediterranean Mud Volcanoes: Implications of Fluid Transport and Fluid Origin

The pore water chemistry of mud volcanoes from the Olimpi Mud Volcano Field and the Anaximander Mountains in the eastern Mediterranean Sea have been studied for three major purposes: 
1) modes and velocities of fluid transport were derived to assess the role of (upward) advection, and bioirrigation for benthic fluxes. 
2) Differences in the fluid chemistry at sites of Milano mud volcano (Olimpi area) were compiled in a map to illustrate the spatial heterogeneity reflecting differences in fluid origin and transport in discrete conduits in near proximity. 
3) Formation water temperatures of seeping fluids were calculated from theoretical geothermometers to predict the depth of fluid origin and geochemical reactions in the deeper subsurface.
No indications for downward advection as required for convection cells have been found. Instead, measured pore water profiles have been simulated successfully by accounting for upward advection and bioirrigation. Advective flow velocities are found to be generally moderate (3-50 cm y- 1) compared to other cold seep areas. Depth-integrated rates of bioirrigation are 1-2 orders of magnitude higher than advective flow velocities documenting the importance of bioirrigation for flux considerations in surface sediments. Calculated formation water temperatures from the Anaximander Mountains are in the range of 80 to 145 Â°C suggesting a fluid origin from a depth zone associated with the seismic decollement. It is proposed that at that depth clay mineral dehydration leads to the formation and advection of fluids reduced in salinity relative to sea water. This explains the ubiquitous pore water freshening observed in surface sediments of the Anaximander Mountain area. Multiple fluid sources and formation water temperatures of 55 to 80 Â°C were derived for expelled fluids of the Olimpi area.

Building Survey in the Southbank Business District - Flyer

Knowledge of the nature of buildings within business precincts is fundamental to a broad range of decision making processes, including planning, emergency management and the mitigation of the impact of natural hazards. To support these activities, Geoscience Australia has developed a building information system called the National Exposure Information System (NEXIS) which provides information on buildings across Australia. Most of the building level information in NEXIS is statistically derived, but efforts are being made to include more detailed information on the nature of individual buildings, particularly in business districts. This is being achieved in Southbank through field survey work.

ARCHIVED - Australian National Exposure Information System (NEXIS) Data Collection

As of 17-June-2025, the National Exposure Information System (NEXIS) was no longer maintained by Geoscience Australia and was decommissioned with all products and data retired. For further information please contact Client Services via ClientServices@ga.gov.au.
The Australian National Exposure Information System (NEXIS) collates the best publicly-available information, statistics, spatial and survey data into comprehensive and nationally-consistent exposure information datasets. Where data is limited, models are used to apply statistics based on similar areas. Exposure Information products are created at the national, state or local level to understand the elements at risk during an event or as a key input for analysis in risk assessments. 
Value: NEXIS products are not intended for operational purposes at the building or individual feature level. Its strength is to provide consistent aggregated exposure information for individual event footprints or at standard community, local, state and national geographies such as the Australian Bureau of Statistics (ABS) Statistical Areas (SA) or Local Government Areas (LGA). 
Scope: National detailed exposure information of the number of people, dwellings, other buildings and structures, businesses, agricultural and environmental assets.

Regional climate change impact modelling for Mandurah, Western Australia

This report describes a detailed assessment of coastal vulnerability and infrastructure exposure undertaken for Mandurah local government area (LGA) to complement the analyses in the National Coastal Risk Assessment.  The assessment modelled both storm surge and coastal recession. The hydrodynamic storm surge modelling conditions were based on those observed during TC Alby (1978) and included scenarios with the storm track shifted to create maximum impact of the wind field on Mandurah, and sea-level rise scenarios from 0.0 m (current climate) to 1.1 m.  Potential shifts in the shoreline position were modelled based on changes in the sediment transport regime under sea-level rise. The resulting inundation from the modelled surge and erosion event was projected onto the coastline to give impact 'footprints' for each event. These footprints were overlaid with built asset data from Geoscience Australia's National Exposure Information System (NEXIS), as well as road, railway and bridge infrastructure. The storm modelling exposure analysis found that if the 1978 Tropical Cyclone Alby storm were to directly impact Mandurah LGA today then approximately 560 buildings are exposed to storm-tide inundation.  This exposure increases to nearly 3,000 buildings when factoring in a rise in sea level of 1.1m by 2100. Within the area modelled to be potentially subject to erosion due to sea-level rise by 2030 there are between 140 and 800 buildings.  However, by 2100 the range increases to between 2,300 and 4,100 buildings.  This study has provided fundamental coastal process predictions that can better enable adaptation plans; and a benchmark of coastal vulnerability to inundation and erosion for the City of Mandurah against which the success of future adaptation initiatives can be measured. With refinements, the modelling methodology presented here is capable of being utilised across Australia to further quantify our coastal vulnerability.

IMOS - Ships of Opportunity - Underway pCO2 System Overview

The CSIRO Ships of Opportunity Underway pCO2 system is mounted on the Research Vessel Southern Surveyor (IMOS platform code: VLHJ) of the Australian Marine National Facility.
CO2 System Overview:
The fugacity of carbon dioxide (fCO2) in surface seawater is measured using a General Oceanics Inc. automated system (Model 8050; Pierrot et al 2009). Seawater is sprayed into an equilibration chamber and CO2 in the headspace gas equilibrates with the seawater. The headspace gas is pumped through a thermoelectric condenser followed by a nafion drying tube before flowing through a Licor 7000 non-dispersive infrared gas analyser that is used to measure the CO2 mole fraction (XCO2) of the dried air. The gas flow is stopped temporarily for the CO2 measurements, which are made at atmospheric pressure. A set of four CO2 in-air standards that cover the range of CO2 values expected in the ocean are analysed about every four hours to calibrate the gas analyser. The standard gas concentrations are on the WMO-X2007 mole fraction scale for CO2-in-air. Atmospheric XCO2 (dry) is measured immediately after the standards by pumping clean outside air from an intake on the forward mast of the ship. 
Seawater intake and ancillary data:
The ships seawater intake is located at about 5.5m depth in the bow of the ship. Sea surface salinity is measured using a thermosalinograph (Seabird Electronics SBE21) located next to the CO2 system. A remote temperature sensor (Seabird Electronics SBE 38) located at the intake is used to measure sea surface temperature (SST). The travel time between the intake and CO2 system is typically about 4 minutes with warming usually less than 0.6ºC. The thermosalinograph water is from the same intake, but the supply lines separate after the intake. A comparison of thermosalinograph and equilibrator temperature records shows the temperature difference in the two lines is generally less than 0.1ºC. The thermosalinograph water line travels outside the ship and is typically warmer than the equilibrator. The travel time in water line to the thermosalinograph is 2.5 minutes faster than the equilibrator. 
Meteorological data, salinity, SST, and ships position and time are taken from the ships logging system. These parameters and the data quality are maintained by the Australian Marine National Facility.
