    Temperature at different depths

    This product highlights how the temperature varies with depth. The eReefs Hydrodynamic model contains over 40 depth slices (6 are available in this visualisation) allowing us to see how the water cools with depth and how cool water is mixed by extreme events such as cyclones.  The Elevation drop down list allows switching between shallow water depths (1.5 m, 18 m, 49 m) and deep depths (103 m, 200 m and 315 m). Note that most of the Great Barrier Reef has a depth of less than 100 m, so as the depth is increased, less of the reef area is visible on the map.

    The shallow water depths are useful for investigating whether corals not at the surface (18 m) were also subjected to high temperature conditions during bleaching events. We can see in the March 2016 video that the high temperature conditions leading to bleaching were also persistent at depths of 18 m. 

    The deep water depths are useful for looking at the mixing effects of cyclones. Slow moving cyclones build up circular ocean currents that can mix the water down to 300 m. This can be seen with Cyclone Nathan in March 2016
