NESP TWQ Round 2 - Project 2.1.6 - From exposure to risk: novel experimental approaches to analyze cumulative impacts and determine thresholds in the GBRWHA

Region map

Understanding cumulative impacts from multiple stressors will be critical for successful management of the GBR under the Reef2050 Plan. The project will produce experimental analyses of concentration-response relationships for selected species under broad, controlled envelopes of sediments, turbidity, nutrients, light, salinity and temperature. Based on new understanding of threshold exposure values, existing and new field data we will produce exposure maps for individual stressors and explore techniques to summarise those into cumulative exposure maps. Results will inform spatial and temporal assessments of ecological risks, and management opportunities for a range of activities in the coastal zones and inshore GBR waters.
