The escalating frequency and severity of marine heatwaves are driving factors behind mass coral bleaching, necessitating both rapid emission reductions and the development of scalable intervention tools. Shading coral to reduce irradiance stress is a promising approach, yet most studies focus on static structures, and few include recovery dynamics. Here, we tested the efficacy of a laboratory-scale seawater fogging system as a...

A photophysiological model of coral bleaching simulates declines and recovery during an emulated multi-doldrum marine heatwave eventNARA Subscribed
Mass coral bleaching events have become increasingly frequent since the 1980s as sea surface temperatures have risen. Extremes of light and temperature stress leading to coral bleaching can develop when doldrum meteorological conditions occur during a marine heatwave event. The coral bleaching model simulates bleaching by tracking the build-up of reactive oxygen species driven by temperature-mediated, light-driven oxidative st...
Light is critical to coral growth through endosymbiont photosynthesis but can also act with elevated temperatures to cause coral bleaching. When more light is absorbed than can be used for photosynthesis, elevated irradiance can damage symbiont photosynthetic machinery. Hence, solar-radiation management through shading has been suggested to alleviate coral bleaching during marine heatwaves. Acropora divaricata and Acropora ken...
The health of coral reefs is declining from the effects of human activity and climate change. Mass coral bleaching is often triggered by elevated water temperature and excessive solar irradiance. Shading can reduce coral bleaching risk. Shading-based management interventions, such as whole-of-reef marine fogging, have been proposed as a conservation tool for periods when coral undergoes excessive thermal stress. This study exa...
