Hydrological Processes
The hydrological processes that affect the Great Barrier Reef include water temperature, water clarity, water salinity and ocean currents. The water has to be between 20 and 30 degrees Celsius. If the temperature is above or below the required temperature, the coral will die causing coral bleaching. The water also has to be clear in order for the sunlight to reach the zooxanthellae, as the zooxanthellae need sunlight to photosynthesis. Ocean currents can bring cold water which can kill coral.
