Water Quality Research

Water quality in the Great Barrier Reef (GBR) has been recognized as being in a state of decline. The rapid expansion of agriculture and urbanization in the GBR catchment is the primary cause of this decline. River discharge carrying land-based pollutants result in both acute and chronic stress on coral reefs and seagrass beds. Chronic stresses associated with increased levels of nutrients and turbidity can affect species susceptible to long-term changes in ambient environmental conditions such as the corals, seagrass and fish species found in the GBR.
