AIMS eReefs Visualisation Portal

In this portal you will find a range of visualisations of the eReefs Hydrodynamic and BioGeoChemical models of the Great Barrier Reef. These models are like weather models, but for the marine environment, providing a picture of the current environmental conditions on the Great Barrier Reef and what has happened in the past. Here you can see past extreme weather events such as:

This site provides both direct visualisations of the outputs of the eReefs Hydrodynamic and BioGeoChemical models and aggregations of the hourly and daily data to longer time periods, such as monthly, annual and all-time (approx. 6 years).

eReefs Hydrodynamic model

The eReefs hydrodynamic model predicts the movement of water, as well as key environmental conditions such as water temperature and salinity, which is useful to seeing freshwater run off from rivers. This model allows us to better understand the path of cyclones and how they mix the water, the location of potentially damaging heat waves that can cause coral bleaching, the ocean currents that disperse larve of corals and Crown-of-Thorns starfish, and fresh water plumes from flooded rivers that can damage inshore reefs.

This model is run with a 4 km and 1 km grid size. The 4 km grid has a longer hindcast going back to Sept 2010, while the 1 km model starts in Dec 2014. The 1 km model also only extends out to the edge of the Great Barrier Reef, where as the 4 km model covers much of the Coral Sea.

eReefs BioGeoChemical model (4 km)

The GBR4 BioGeoChemical (GBR) model builds on the GBR4 hydrodynamic model by using modelling the water quality (nutrients and suspended sediment) and key ecological processes (coral, seagrass, plankton) that drive the water chemistry. This model allows us to better understand how water quality is affected by land runoff. These visualisations are based on the v924 version of the BioGeoChemical model that is updated in near-real time.
