This page shows salinity at different depths on the Great Barrier Reef based on the 1km eReefs Hydrodynamic model.
Recent data
The results are updated in near-real-time, however sometimes they can be behind real time up to 2 weeks. This happens due to delays in the model runs being held up for technical reasons or delays in source data that drive the model. This visualisation portal can sometimes also delay the products by up to 1 day. To check the latest available model data look at the date on the NCI THREDDS server. If the model data is more up to date than this portal let us know.
Navigation
These pages can show a combination of videos and images dependent on the underlying data. Make a selection via the tabs in the "Time step" panel at the top of the visualisation. The content type (video or image) is identified by the icon in the corresponding tab.
The interactive map below the visualisation (left) allows for zooming in on a particular region, or all of Queensland. Where applicable, the interactive map is accompanied with a list of the regions for clarity.
The calendar below the visualisation (right) selects the data range of the visualisation. Individual months and/or entire years can be selected when supported by the underlying data.
Salinity at different depths
The salinity of normal ocean water is approximately 35 PSU. As freshwater is mixed with the ocean water the salinity drops, with pure water having a PSU of zero. This product highlights that, absent forced mixing from current upwelling (such as by cyclones), lower salinity water floats to the surface (represented on this page by the 2.35m depth).
