AIMS eReefs
Current at 2.35m, 18m and 103m depth (GBR1)
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.
This page shows the strength and direction of ocean currents at different depths on the Great Barrier Reef based on the 1km 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 and and out of a region.
Erratum
From 28 Dec 2014 - 29 Dec 2014 and from 1 Dec - 10 Dec 2021, the forcing data for the GBR1 eReefs model was incorrect due to a process failure while extracting the relevant ACCESS data. This resulted in static tides and winds during this period, leading to incorrect model outputs during Dec 2014 and 2021, with some carry over error into Jan 2022. This forcing error led to a decrease in water mixing resulting in the temperature building up several degrees hotter than it should and to the flood plumes from the Fitzroy and Burnett moving in the wrong direction.
CSIRO are correcting this problem by re-running the model from Dec 2021 for several months to replace this section of the data. This warning will be updated when this change has been made.
