Note: The GBR1 and GBR4 models (including hydro, river tracer and BGC) are no longer updated in near-real-time. New model outputs may be added in the future.
This page shows the strength and direction of ocean currents at different depths on the Great Barrier Reef based on the 4km eReefs Hydrodynamic model.
Current at different depths
This map is useful for investigating the depth of various ocean currents. The strength of the current is represented by colour. The arrows represent the direction. In the hourly data a lot of the daily fluctuations are due to tidal currents. These tend to make the current direction swing back and forth as the tides flow in and out of a region.
Source data
The videos/images on this page are based on the 4km eReefs Hydrodynamic model (v2.0) of the Great Barrier Reef. The raw data is available from the NCI THREDDS server (hourly) and the aggregate data from the AIMS eReefs THREDDS server (daily, monthly, yearly and overall). These map layers are also available for inspection in the eReefs Data Explorer.
Data coverage
The data on this page may not reflect the most current conditions, as the GBR1 and GBR4 model runs are no longer updated on a regular basis.
To browse the latest available model data, refer to the NCI THREDDS server.
