NESP TWQ Round 2 - Project 2.1.6 - From exposure to risk: novel experimental approaches to analyse cumulative impacts and determine thresholds in the GBRWHA
Understanding cumulative impacts from multiple stressors is critical for successful management of the GBR under the Reef2050 Plan. The project produced 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 the project has enabled exposure maps for individual stressors to be produced and exploratory techniques to summarise those into cumulative exposure maps. Results have informed spatial and temporal assessments of ecological risks, and management opportunities for a range of activities in the coastal zones and inshore GBR waters.

Datasets
This dataset contains data from experiments testing the survival of fertilised Acropora millepora gametes before and after settlement in different climate and sediment treatment conditions.
This dataset consists of one data file presenting data from 4 experiments conducted under aquarium controlled conditions manipulating levels of suspended sediments, temperature and nutrient enrichment.
This dataset shows the measured response of early life history stages to different levels of nutrient enrichment and temperatures in experiments conducted in 2014-2015.
The aim of this study was to investigate the effects of the herbicide diuron and climate change on the Photosystem II activity of the seagrass Halophila ovalis.
This dataset consists of two data files (spreadsheets) from a 15 days experiment simulating the combined effects of climate change (manipulated temperature and pCO2 from present days and predicted for 2050 and 2100) and diuron contamination.
