The Bureau of Meteorology’s Groundwater information suite provides details about this largely hidden resource around Australia.
[Graphic showing the four products in the Groundwater Information Suite (Insight, Explorer, Information System, Ecosystems Atlas)]

First, let’s take a look at the Australian Groundwater Insight.

This is a web mapping application that provides broad scale groundwater information to non-technical users.
[Australian Groundwater Insight website: 'Overview' page; then cursor clicks on 'Bore information' page; then cursor clicks on 'Water levels' map to enlarge map]

Zoom in to see bore information, such as bores with water level data.
[Map zooms in to show water level readings in Victoria and South Australia]

Hydrogeology maps, like aquifer boundaries, show the aquifers at different depths below the ground.
[Cursor clicks on 'Hydrogeology' page; then cursor clicks 'Aquifer boundaries' map to enlarge map]

Maps of Groundwater entitlements show the locations of groundwater extraction licences.
[Cursor clicks on 'Groundwater entitlement'page; then cursor clicks on 'Licensed groundwater entitlement' map to enlarge map]

There is information about Groundwater management,
[Cursor clicks on 'Groundwater management' page; then cursor clicks on 'Groundwater management areas' map to enlarge map]

as well as the status of groundwater levels at bores, indicating whether they are below average, average or above average.
[Cursor clicks on 'Groundwater level status' page; then cursor clicks on 'Upper groundwater status 2016' map to enlarge map]

It also has Groundwater level trends, to show whether levels are rising, stable, or falling,
[Cursor clicks on 'Groundwater level trend' page; then cursor clicks on '5 year trend middle' map to enlarge map]

and information on the salinity of groundwater.
[Cursor clicks on 'Groundwater salinity' page; then cursor clicks on '20 year average salinity 1997-2016' map to enlarge map]

Now let’s get more technical. 

The Australian Groundwater Explorer is a web mapping application for groundwater experts.
[Australian Groundwater Explorer website: default view of map of Australia showing 'All bores' layer]

You can zoom into your area of interest, 
[Cursor uses 'zoom' tool to zoom in to an area near Adelaide]

add other map layers like rivers and lakes, and
[Cursor clicks 'Hydrology' from 'Layers' menu to turn on rivers and lakes layers]

view groundwater measurements for bores including water levels and salinity.
[Cursor clicks 'Groundwater measurements' from 'Layers' menu to display water level readings; then cursor selects 'Salinity' to display salinity readings]

You can also investigate the purpose of the bores, such as monitoring, irrigation, or stock and domestic.
[Cursor clicks 'Bore purpose' from 'Layers' menu and turns on 'Monitoring', 'Irrigation' and 'Stock and domestic' bore layers]

You can select a specific bore to view its data,
[cursor turns on 'Water level' layer; then clicks the 'Circle Select' tool; then selects specific bore; then selects 'View Data' from the 'Search Results Panel' which brings up 'Results' window]

And use water-level charts, to compare against average levels and rainfall trends.
[Cursor clicks 'Water level chart' tab in 'Results' window to display charts for Standing water level and Resuced standing water level]

You can view salinity charts
[cursor clicks 'Salinity chart' tab in 'Results' window to display charts for total dissolved solids and electrical conductivity]

and bore log charts to see lithology, construction and hydrostratigraphy.
[Cursor clicks 'Bore log chart' tab in 'Results' window to display lithology, construction and hydrostratigraphy logs]

There are also 3D aquifer models.
[Cursor closes 'Results' window, and clicks on '3D' button on tool bar. This brings up a 3D Viewer menu of available 3D regions]

Let’s look at the Murray Basin.
[Cursor cilcks on Murray Basin from 3D Viewed menu]

Viewed in interactive PDFs you can turn aquifer layers on and off and rotate the model.
[View of 3D PDF; cursor turns layers on and off using Model Tree menu, and rotates the model by clicking and dragging within PDF window]

Underpinning everything is the National Groundwater Information System.

In Australia, groundwater data is collected and managed by State water agencies. This data is collated and standardised in a national database. 
[Graphic of Australia split into individual states; arrows link each state to the 'National Groundwater Information System' database']

You can download the full database or access data through products like the Groundwater Explorer.
[Graphics show options of downloading full database or accessing via products]

The final part of the suite is the Groundwater Dependent Ecosystems Atlas.

This is a spatial inventory of groundwater-dependent ecosystems, or GDEs, in Australia. 
[Graphic showing a 3D block diagram of GDEs in the landscape, including streams, wetlands, vegetation]

It maps the location of GDEs and provides information about ecology and hydrogeology.

It has information about three GDE types:
[Shot of GDE Atlas web mapping portal interface, showing national Aquatic GDE map layer]

Aquatic, such as wetlands, rivers and springs;
[Cursor points to Aquatic GDE layer from 'Layers' menu panel]

Terrestrial, including trees, shrubs and forests; and
[Cursor clicks on Terrestrial GDE layer from 'Layers' menu panel; map displays national Terrestrial GDE map layer]

Subterranean GDEs, such as caves.
[cursor clicks on Subterranean GDE layer from 'Layers' menu panel; map displays national Subterranean GDE map layer]

You can zoom into your area,  
[cursor turns on Aquatic GDE layer; then selects 'zoom' tool from toolbar; then zooms in on area in Queensland]

and select specific GDEs to find out more about them.
[Cursor uses 'Circle Select' tool from toolbar to select specific GDEs; detailed information displays in the 'Search Results' panel]
