A national-scale vulnerability assessment of seawater intrusion: coastal aquifer typology

Fresh groundwater stored in Australian coastal aquifers constitutes an important resource for humans and the natural environment. However, many Australian coastal aquifers are vulnerable to seawater intrusion the landward encroachment of seawater into coastal aquifers. This report is one technical assessment of the National Seawater Intrusion Project, aimed at characterising current and future seawater intrusion vulnerability of Australian coastal aquifers. This report outlines the development of a typological framework to categorise coastal aquifers and assist in their assessment of vulnerability. The report includes a characterisation of the different hydrogeological and climatic settings of Australia's coastal aquifer. Using public and confidential information, simplified cross-sectional conceptual models of case study areas were developed and aquifer parameters were tabulated for 28 case study areas (CSAs). Key hydrogeological characteristics are analysed and tabulated for use in other aspects of the overall vulnerability assessment.

Outer Darwin Harbour Marine Survey 2015: p-rock (probability of rock) grid

This resource contains probability of rocky/hard seabed (multibeam angular backscatter response derived product) grid for Outer Darwin Harbour collected by Geoscience Australia (GA), the Australian Institute of Marine Science (AIMS) and the Northern Territory Government (Department of Land Resource Management) during the period from 28 May and 23 June 2015 on the RV Solander (survey SOL6187/GA0351). This project was made possible through offset funds provided by INPEX-led Ichthys LNG Project to Northern Territory Government Department of Land Resource Management, and co-investment from Geoscience Australia and Australian Institute of Marine Science. The intent of this four year (2014-2018) 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 that underpin marine resource management decisions. The specific objectives of the survey were to: 1. Obtain high resolution geophysical (bathymetry) data for outer Darwin Harbour, including Shoal Bay; 2. Characterise substrates (acoustic backscatter properties, grainsize, sediment chemistry) for outer Darwin Harbour, including Shoal Bay; and 3. Collect tidal data for the survey area. Data acquired during the survey included: multibeam sonar bathymetry and acoustic backscatter; physical samples of seabed sediments, underwater photography and video of grab sample locations and oceanographic information including tidal data and sound velocity profiles. This dataset comprises  probability of rocky/hard seabed (multibeam angular backscatter response derived product) grid.

DEA Coastal Ecosystems

Mapping coastal ecosystems is vital for understanding, managing, and protecting the diverse habitats that line our shorelines. These ecosystems—ranging from mangroves and saltmarshes to seagrass meadows and coral reefs—provide essential environmental services, including carbon storage, coastal protection, and habitat for marine biodiversity. From an economic standpoint, they sustain industries such as fisheries and tourism while reducing costs associated with coastal erosion and storm damage. Accurate and comprehensive mapping underpins management, restoration, and conservation efforts, allowing planners to identify priority areas, monitor ecological change, and assess the effectiveness of interventions.



Achieving this at a continental scale, however, poses significant challenges. Traditional methods such as field surveys, aerial photography, and local-scale sampling are costly, labour-intensive, and constrained in spatial and temporal scope—limitations that are particularly relevant in a country as vast and remote as Australia. Earth Observation (EO) provides an efficient and consistent alternative, allowing large-scale, high-resolution, and repeatable mapping through the use of publicly available satellite imagery.



The&nbsp;Digital Earth Australia (DEA) Coastal Ecosystems&nbsp;product suite (https://knowledge.dea.ga.gov.au/data/product/dea-coastal-ecosystems/) is the first national dataset to simultaneously map Australia’s mangrove, saltmarsh, intertidal, and intertidal seagrass ecosystems at 10 m resolution, using annual time-series of Sentinel-2 satellite imagery for consistent mapping at a continental scale.&nbsp;





Applications



- National Environmental Ecosystem Accounts

- National and Regional State of the Environment reporting

- A complementary mapping product to fill spatial and temporal gaps in higher resolution expert mapping (aerial and drone mapping, field surveys)

- Future integration with other terrestrial and ocean data sets (e.g. Land Cover and Marine Tenure)

- Coastal protection and Hazard modelling

L032 Haddon Downs experimental seismic survey, SA, 1957

An experimental seismic survey was conducted at Haddon Downs, South Australia, during Octobor and November.1957. The area lies within the Eromanga Sub-basin of the Great Artesian Basin, and at least 5,500 feet of Mesozoic section are known to exist there, part of which is of a marine facies. Preliminary reconnaissance work by geologists of Santos Ltd. which holds an Oil Prospecting Licence over the
area, revealed some large anticlines on the surface. The Company has already completed a limited amount
of gravity work which gives promise of supplying useful information on both regional and detailed subsurface structure.

Two important refractors were recorded which may be useful for semi-regional mapping. A refractor of velocity 10,250 ft/sec. was recorded from a depth of about 2,700 feet, and this may represent the top of the marine Cretaceous section. The second refractor of velocity 17,000 ft/sec. and aidoroximate depth 7,250 feet may be just below the base of the Mesozoic section.

Large multiple geophone arrays and pattern shots were needed to obtain good quality reflections over most of the area, except when shooting on the alluvial plains of the larger creeks. The sedimentary section was shown to be at least 8,000 feet and possibly 16,000 feet thick, The base of the Mesozoic section is interpreted as being 7,250 feet deep on the refraction traverse and 8,600 feet at the south-east end of the reflecta.on traverse. The rest of the section probably consists of Palaeozoic sediments. If so, the high velocity (17,000 ft/sec.) suggests that a dense elastic or crystalline limestone is probably present near the top of them. The structure of the Mesozoic section is subhorizontal, but there may be minor structures with dips less than 1 degree which correlate with the surface structures.

A non-marine Lower Cretaceous rift-related epiclastic volcanic unit in southern Australia: the Eumeralla Formation in the Otway Basin.  Part I: Lithostratigraphy and depositional environments

The Early Cretaceous non-marine volcaniclastic Eumeralla Formation accumulated in a rift basin on the southern margin of Australia during the break-up of eastern Gondwana.  Wireline-Iog analysis and a range of sedimentary data have helped to discriminate three major basin-wide informal lithostratigraphic units in the formation.  From the base of the formation they are: Eumeralla I: siltstone/mudstone/sandstone/coal; Eumeralla II: siltstone/mudstone/thin lithic sandstone; and Eumeralia III: volcaniclastic sandstone. A fourth unit - Eumeralla IV: siltstone/sandstone/coal - occurs throughout the western Otway Basin, but is absent, probably because of erosion, from the central and eastern pans of the basin.  The bases of all four lithostratigraphic units are probably diachronous.  The succession of lithostratigraphic units Eumeralla I- IV is interpreted as representing coal swamps and flood plains of low-energy streams; shallow and deep freshwater lakes; channel tracts and flood plains of high-energy streams; and channel tracts, flood plains and coal swamps of low- energy streams respectively.  Sedimentary facies analysis of outcropping Eumeralla II and Eumeralla III in the eastern Otway Basin confirms the interpretations for these units.  The basin-wide extent of the three lower lithostratigraphic units implies that a single integrated drainage system for the entire basin was established at the onset of Eumeralla Formation deposition, and persisted at least until the late Albian.  This inference is supported by the close correlation between variations in lithology and depositional environments and the Aptian- Albian sea-level changes.  However, intrabasinal volcanism significantly influenced sedimentation and was probably the primary control on basin drainage.

Continuity of Earth Observation Data for Australia - Operational Requirements to 2015 for Lands, Coasts and Oceans

Earth Observations from Space describes a range of approaches that observe and measure Earth surface properties from space-based platforms. Earth Observations from Space data is used widely and to great advantage in Australia by numerous federal and state government agencies, research institutions, and the private sector, and have particular value in a large, sparsely populated country that needs to monitor a long coastline and a wide range of natural disasters. Australias involvement in international agreements that require recording, monitoring and reporting on environmental change also necessitates the use of Earth Observations from Space data.

Timor Sea continental shelf sediments map

Since the publication in 1967 of the monograph on the marine geology of the Timor Sea,1 the Bureau of Mineral Resources has initiated a program of systematic reconnaissance geological surveys of the continental shelf. The results of this work are being published in the BMR Bulletin series accompanied by 1:1 000 000 lithofacies maps of the shelf sediments. Three sheets (Rowley Shoals, W.A.2; Scott Reef, W.A.2 ; and Arafura Sea, N.T.8 ) have been printed by early 1974, and work on two further sheets covering part of the east Australian continental shelf is well advanced. Users of the map should refer to Bulletin 83 (GeoCat # 163) to assist in interpretation. For instance, wide areas of the shelf are non-depositional, or even subject to erosion, and therefore the variations in lithology portrayed are not exclusively the result of variations in the modern depositional regime. Also the map does not distinguish sediments which are relics of earlier regimes from modern ones; however, some information of the distribution of these older sediments can be obtained from Bulletin 83 (GeoCat # 163) and inferred from a study of the gravel content in relation to the bathymetry.

Fast Repetition Rate Fluorometry (FRRF) data collected on the RV L'Astrolabe from 05/12/2003 to 11/12/2003 (Hobart - Dumont d'Urville)

These data were collected on the RV L'Astrolabe (platform code: FHZI) from 05/12/2003 to 11/12/2003on a trip from Hobart to Dumont d'Urville.

Maximum photochemical efficiency of photosystem II (PSII), also called maximum quantum yield of PSII (Fv/Fm), has become one of the most widely utilized fluorescence parameters in phytoplankton research. It represents the potential photochemical efficiency, which is the probability that the light energy captured by the photosynthetic apparatus is being utilized as photochemistry. Fv/Fm has been shown to have an instant response to variations in physical and chemical properties and is interpreted as a diagnostic of the overall health or competence of phytoplankton. Together with the absorption cross section area of PSII and chlorophyll concentration, it can be used to measure primary production (Cheah et al. 2011, Deep Sea Research).

Seawater from 3 m depth was supplied continuously from the ship’s clean seawater line. FRR fluorescence yields were measured continuously at 1 minute intervals in dark-adapted state (! 15 minutes dark-adaptation) using a flash sequence consisting of a series of 100 subsaturation flashlets (1.1 μs flash duration and 2.8 μs interflash period) and a series of 20 relaxation flashlets (1.1 μs flash duration and 51.6 μs interflash period).
