Salinity categories are not defined further than 6,000 mg/L which has been used to represent the saltwater interface. This dataset is a derived location based on an assessment of data for the period November 2020 to November 2021. The 2016 Interpretation of TEMPEST Airbourne Electromagnetic Data from Esperance (Mira Geoscience) was also used in creating this dataset. This location can change pending known factors that impact the location of the seawater interface including the time of year, tidal movements, abstraction, recharge and throughflow. The full assessment of the SWI in this area is documented in report HR437 Esperance Seawater Interface Priority Area Assessment. This dataset is sourced from the Statewide Seawater Interface Project, funded by the Government of Western Australia under the State Groundwater Investigation Program. In the Esperance area, the project runs from April 2020 to March 2023 and the data are collected from: - Seawater interface monitoring (SWIM) bores installed or owned by the department - Downhole natural gamma and induction logging - Installation of data loggers and continuous static groundwater level (SWL) measurements from data loggers - Electrical conductivity (EC) depth profiling - Groundwater chemistry sampling. - Airborne electromagnetic (AEM) survey. The above data that is owned by the department can be downloaded from the Water Information Reporting (WIR) Portal or by contacting the Department. AEM survey data can be downloaded via the interactive geological map tool GeoVIEW.WA from the Department of Mines, Industry Regulation and Safety. Information on the SWI project can be found on the Western Australia State Government website (www.wa.gov.au). {"type": "Polygon", "coordinates": [[[121.73752503600008, -33.902074374999984], [121.94009897900003, -33.902074374999984], [121.94009897900003, -33.816174108999974], [121.73752503600008, -33.816174108999974], [121.73752503600008, -33.902074374999984]]]} 121.73752503600008 121.94009897900003 -33.902074374999984 -33.816174108999974 Coastal Seawater interface Superficial aquifer brackish groundwater coastal aquifer fresh groundwater groundwater abstraction groundwater investigations groundwater priority areas hypersaline groundwater mixing zone saline groundwater salinisation saltwater interface saltwater intrusion seawater interface monitoring seawater intrusion state groundwater investigation program water table aquifer Seawater interface salinity distribution 10 m below water table – Esperance documentDigital DEPARTMENT OF WATER AND ENVIRONMENTAL REGULATION (DWER) Metadata and Data Dictionary Statement TXT Licence Agreement documentDigital DWER Active Acceptance Licence Agreement PDF Shapefile documentDigital This resource provides the latest snapshot of the dataset as a shapefile.

GeoJSON Web Feature Service documentDigital Web Feature Service (WFS) provides an interface that allows requests for geographical features across the web using platform independent calls. WFS allows a user to download and spatially analyse the features within a datset. This service is aimed at advanced geographical information users, and will require access to geographical information system (GIS) software such as QGIS and ArcGIS. WFS ArcGIS Server Map Service documentDigital An ArcGIS Server Map Service offers access to a geographic dataset - such as a map or imagery - by providing a set of tiled images for use in web-based maps. Depending on the capabilities enabled, this web service may also allow a client to dynamically draw, search, and query its features. This service is aimed at advanced geographical information users, and will require access to geographical information system (GIS) software such as ArcGIS and QGIS. API ArcGIS Server Map Service Web Mapping Service documentDigital Web Map Service (WMS) is a standard protocol for serving georeferenced map images over the internet that are generated by a map server using data from a GIS database. WMS allows a user to spatially visualise the dataset, and query individual features, but does not allow downloading the raw data.
