Current at 1.5m, 18m and 103m depth (GBR4)

Time step:

    Note: The near-real time GBR1 and GBR4 models (including hydro, river tracer and BGC) are currently paused at December 17th 2023 due to infrastructure damage from the recent flooding events around the Daintree River region (see here). These floods have damaged the real-time river temperature and flow sensors across surrounding catchments, and Queensland government is working to recover and restore these as quickly as possible. We will provide further updates when available.

    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 and and out of a region.
