Brief description The Reef Rescue Marine Monitoring Program (RRMMP) has identified that seagrass meadows along the Great Barrier Reef are in a state of decline. This project will undertake desktop analyses to quantify the exposure of seagrass meadows to flood plumes. Aquaria experiments will measure responses of seagrass to variation in light, nutrients and salinity. This project will also use use True Colour Remote sensing images, to derive flood plume exposure and relate to changes in seagrass abundance and composition. The results will be synthesised to define thresholds of concern of water quality impacts, with a particular focus on flood plumes, and input into the development of guidelines for the protection of seagrass meadows. Tasks include: 1. Quantifying the level of exposure of seagrass meadows to changes in water quality associated with flood plumes (using True Colour Remote sensing) in coastal regions of the GBR. 2. Measurement of changes in biological traits (e.g. growth, biomass) of seagrass in relation to water quality (Light, nutrients, salinity) determined by experimental studies. 3. Experimental testing of indicators of seagrass status adopted in the Great Barrier Reef Marine Monitoring Program (MMP) (e.g. nutrient ratios) in response to changes in water quality. 4. Experimental verification of water quality response models and thresholds, in particular in relation to the MMP.
