What’s really damaging the Reef?: Tracing the origin and fate of the ecologically detrimental sediment and associated bioavailable nutrients
Other Publication ResearchOnline@JCUAbstract
This report addresses six key systematic questions to help inform the debate on the influence of anthropogenic sediment and associated particulate nutrients delivered to the Great Barrier Reef (GBR) lagoon. They are: 1. What is the influence of the newly-delivered sediment (i.e. from flood plumes) on turbidity regimes at coral reef and seagrass locations of the inshore GBR? 2. What is the contribution of the anthropogenic component of this sediment on turbidity regimes? 3. What are the characteristics of the suspended particulate matter (and associated particulate nutrients) that influence light and turbidity regimes and how do these change over the estuarine mixing gradient of flood plumes? 4. How does the particulate organic component of the suspended particulate matter and associated microbial community composition change from the catchment to reef? 5. How bioavailable is the suspended particulate matter along the estuarine mixing gradient 6. Where does the sediment (and associated particulate nutrients) that influence light and turbidity regimes in the GBR come from in the Burdekin catchment so that management efforts can be prioritised? This final project report is divided into eight separate stand-alone research chapters which collectively address these six key questions.
