GBR Resilience Model

Quantitative linkage between upper thermal bleaching limits (°C) and the degree of exposure to nutrient enriched terrestrial waters (after Wooldridge, 2009a). The bleaching limits are based on a 5-day exposure period. Coastal reef waters with high DIN-enriching impact are characterised by a higher annual exceedence probability (AEP) of [Chl α 0.9 µg.L-1. The quantitative linkage implies that local management efforts to lower end-of-river DIN loads could benefit reefs by acting to raise their thermal bleaching limits.
