This dataset depicts a national map of available ASS mapping and ASS qualification inferred from surrogate datasets. ASS mapping is classified with a nationally consistent legend that includes risk assessment criteria and correlations between Australian and International Soil Classification Systems.

Existing digital datasets of ASS mapping have been sourced from each coastal state and territory and combined into a single national dataset. Original state classifications have been translated to a common national classification system by the respective creators of the original data and other experts. This component of the Atlas is referred to as the “Coastal” ASS mapping. The remainder of Australia beyond the extent of state ASS mapping has been “backfilled” with a provisional ASS classification inferred from national and state soils, hydrography and landscape coverages. This component is referred to as the “Inland” ASS mapping.

For the state Coastal ASS mapping, the mapping scale of source data ranges from 1:10K aerial photography in SA to 1:250K vegetation mapping in WA and NT, with most East coast mapping being at the 1:100K scale. For the backfilled inferred Inland ASS mapping the base scale is 1:2.5 million (except Tas.) overlaid with 1:250k hydography. As at 06/08, the Tasmanian inland mapping has been re-modelled using superior soil classification map derived from 1:100k landscape unit mapping.

NOTE: This is composite data layer sourced from best available data with polygons depicted at varying scales and classified with varying levels of confidence. Great care must be taken when interpreting this map and particular attention paid to the “map scale” and confidence rating of a given polygon. It is stressed that polygons rated with Confidence = 4 are provisional classifications inferred from surrogate data with no on ground verification. Also some fields contain a “-“, denoting that a qualification was not able to be made, usually because a necessary component of source mapping coverage did not extend to the given polygon. Lineage: Coastal ASS component:

Existing state CASS mapping was received and processed to varying degrees to conform to the NatCASS national ASS classification system. Spatially, all datasets were reprojected from their original projections to geographic GDA94. Classification of state mapping polygons to the NatCASS classification system was as follows. In the case of SA, NSW, Qld and WA it was a matter of directly translating the original state ASS classifications to the NatCASS classifications. These translations were undertaken by the creators of the state data and other experts within the respective states.

Due to the more broad classifications of the original Vic and Tas ASS mapping, polygons for these two states were initially translated to a NatCASS classification group (eg Tidal, Non-Tidal) by the data custodians then subsequently differentiated further through intersecting with other layers. These included the 3 second SRTM DEM and North Coast Mangrove mapping GIS datasets. The former being used to differentiate within the Non-Tidal zones (ie classes Ae-j and Be-j) and the latter used to differentiate the Tidal zones (ie Ab-d, Bb-d).

Mapping of the Tidal-Zone classes was augmented for all states except SA and NSW with 1:100K Coastal Waterways Geomorphic Habitat Mapping (Geoscience Australia). This dataset was used to infer additional areas of subaqueous material in subtidal wetland (class Aa & Ba) and Intertidal Flats (class Ab & Bb).

Inland ASS component:

Provisional Inland ASS classifications are derived from National and (in the case of Tasmania) state soil classification coverages combined with 1:250K series 3 Hydrography and Multiresolution Valley Bottom Floor Index (MrVBF).

Abstract

This data and its metadata statement were supplied to the Bioregional Assessment Programme by a third party and are presented here as originally supplied.

This project has mapped the occurrence of Acid Sulfate Soils (ASS) along the coast of NSW and provides information that will assist land management and rehabilitation. In their natural state, these soils are submerged but when exposed or drained, they become oxidised and sulphuric acid is produced. This reduces soil fertility, kills vegetation and reduces fish populations. The identification of the location and extent of potential acid sulphate soils (PASS) is the essential first step in managing this problem. 128 map sheets were mapped for risk of occurrence of ASS at a scale of 1:25,000. This project was co-funded by the Natural Resources Audit Council (NRAC), and was revised in 1997.

Dataset History

The maps predict the distribution of Acid Sulfate Soils (ASS) based on an assessment of the geomorphic environment. This assessment has involved mapping of the environments in which they are likely to be found, being the coastal lowlands up to approximately 10m AHD and carrying out fieldwork to establish field relationships between landform, elevation and occurrence of ASS. Landform elements were used as the basic mapping unit. These provide a basis for land use planning and allow the application of elevation classes so that the depth of occurrence of ASS within a landform element can be estimated. It allows the prediction of soil management problems in other areas with similar landform and soil characteristics. ASS maps are not intended to provide site specific ASS information. The information derived from the maps cannot be used in the assessment of the potential to effectively manage ASS in a particular development. When using ASS maps, it must always be remembered that that there can be expected to be extreme variations in the nature and distribution of of ASS and that the depth to the ASS layer can be highly variable. The depths given in the map key should be used as a guide only and not used for a specific assessment of development potential. It is recommended that all land use activities likely to disturb ASS require appropriate soil investigations and a management plan to avoid environmental degradation.Metadata imported.C:\Program Files\ArcGIS\Metadata\ANZMeta\Thesaurus\temp.xml2008090911100000Metadata imported.D:\SDC\metadata\NSW_ACIDRISK.xml2008090911125700

It is not based upon sampling and analysis.

This dataset describes the presence and depth of actual acid sulfate and potential acid sulfate in soils of the estuarine and floodplain environments of Darwin Harbour, Bynoe Harbour, Shoal Bay, Adelaide River, Fog Bay and Finniss River over approximately 3,350km of Northern Territory coastline. The survey was mapped at a scale of 1:50,000.

Data of the risk of Potential Acid Sulfate Soil (PASS) materials being disturbed by land development activities based on the likelihood of PASS materials occurring within 3m of the ground surface for the Pilbara Coastline. This data is for use by planners to assess whether development applications for specific sites require additional conditions on the basis of whether normal land development activities carry a risk of disturbing PASS materials. The depth of 3m is considered since this was regarded as the depth that most soil disturbance activities would extend during in most land development processes. Disturbance activities in this context include drainage, excavations and dewatering. For further information phone the Contaminated Sites hotline 1300 762 982. This dataset was formerly known as Acid Sulfate Soil Risk Map, Pilbara Coastline (DER-011). This dataset is no longer actively maintained by DWER.

This dataset depicts polygons of acid sulfate soils (ASS) identified as part of the Norfolk Island Water Resource Assessment 2019 - 2020 (NIWRA) and additional targeted work in 2020 - 2023. Areas were mapped due to the importance to water quality of fresh and marine water, groundwater recharge, surface water storage, managed aquifer recharge and impact on infrastructure specifically in the World Heritage listed Kingston and Arthur’s Vale Historic Area (KAVHA). The full extent of ASS has not been identified on NI primarily concentrating to date on areas that support the NIWRA and water quality management in the Kingston area. Acid sulfate soils is the name given to naturally occurring soils, unconsolidated sediments or organic accumulations (peat) in which sulfuric acid will be produced, is being produced, or has been produced in amounts that have a lasting adverse impact to soil, water, infrastructure and the environment. Further acid sulfate soil information can be found in the (a) NIWRA technical report (Petheram et al., 2020) and described in Appendix D of the NIWRA technical report, (b) Norfolk Island Water Resource Assessment: Acid sulfate soils (Fitzpatrick et al., 2023), (c) Acid sulfate soil management in the Kingston and Arthur's Vale historic area (KAVHA) on Norfolk Island (Fitzpatrick et al., 2023) and (d) Management of excavated peaty acid sulfate soil with hypersulfidic material from a potential new Headstone dam on Norfolk Island (Fitzpatrick et al., 2020). This data is an update to the previously released acid sulfate soils of Norfolk Island. Lineage: The acid sulfate soil dataset has been generated from a range of inputs and processing steps. The following is an overview of the methods detailed in Petheram et al. 2020 and Fitzpatrick et al. 2023. 1. Collated existing data (relating to: soils, climate, topography, natural resources, remotely sensed, of various formats: reports, spatial vector, spatial raster). 2. Selection of soil and land attribute site data locations. 3. Fieldwork was carried out to collect new attribute data, soil samples for analysis and build an understanding of geomorphology and landscape processes. 4. Esri ArcMap was used to delineate polygons. Associated datasets used included LiDar, DEM derivatives (TWI, slope), satellite imagery and historical aerial photography. 5. QA Quality assessment of the data was conducted by on-ground expert (qualitative) examination of the mapping.

This project has mapped the occurrence of Acid Sulfate Soils (ASS) along the coast of NSW and provides information that will assist land management and rehabilitation. In their natural state, these soils are submerged but when exposed or drained, they become oxidised and sulphuric acid is produced. This reduces soil fertility, kills vegetation and reduces fish populations. The identification of the location and extent of potential acid sulfate soils (PASS) is the essential first step in managing this problem. 128 map sheets were mapped for risk of occurrence of ASS at a scale of 1:25,000. This project was co-funded by the Natural Resources Audit Council (NRAC), and was revised in 1997.

In this version, (v2.5.1), ASS risk maps have not been remapped, however minor attribution changes to the GIS linework have occurred to fix errors and some additional original information has been incorporated into the attribute tables. This data provides maps of elevation, landform process groups and landform elements for the mapped area. The symbology for the ASS probability risk map classes can also now be simplified to reflect only probability, potential depth from the surface and presence of areas with Pleistocene sediments or ASS scalding.

Related Datasets: The dataset area is also covered by the mapping of the Soil and Land Resources of Central and Eastern NSW and Soil Landscapes of Central and Eastern NSW and Hydrogeological landscapes of NSW.

Online Maps: This and related datasets can be viewed using eSPADE (NSW’s soil spatial viewer), which contains a suite of soil and landscape information including soil profile data. Many of these datasets have hot-linked soil reports. An alternative viewer is the SEED Map; an ideal way to see what other natural resources datasets (e.g. vegetation) are available for this map area.

This spatial dataset identifies areas of land showing the extent of acid sulfate soils. Acid sulfate soils have been classified into 5 different classes based on the likelihood of the acid sulfate soils being present in particular areas and at certain depths.

• Class 1: Acid sulfate soils in a class 1 area are likely to be found on and below the natural ground surface.
• Class 2 : Acid sulfate soils in a class 2 area are likely to be found below the natural ground surface.
• Class 3: Acid sulfate soils in a class 3 area are likely to be found beyond 1 metre below the natural ground surface.
• Class 4: Acid sulfate soils in a class 4 area are likely to be found beyond 2 metres below the natural ground surface.
• Class 5: Acid sulfate soils are not typically found in Class 5 areas. Areas classified as Class 5 are located within 500 metres on adjacent class 1,2,3 or 4 land.

Data of the risk of Potential Acid Sulfate Soil (PASS) materials being disturbed by land development activities based on the likelihood of PASS materials occurring within 3m of the ground surface for the Lower South West Region. This data is designed for use by planners to assess whether development applications for specific sites require additional conditions on the basis of whether normal land development activities carry a risk of disturbing PASS materials. Disturbance risk is rated on the basis of the likelihood of PASS materials being encountered within 3m of the ground surface should this depth of soil be disturbed in any way. The depth of 3m is considered since this was regarded as the depth that most soil disturbance activities would extend during in most land development processes. Disturbance activities in this context include drainage, excavations and dewatering. For further information phone the Contaminated Sites hotline 1300 762 982.
