It harnesses cutting-edge AI and digital tech to transform photos taken by snorkelers and divers into vital data about reef health, which is then shared to communicate where and how reefs are changing. “We can use this to estimate reef composition 700 times faster,” Emma says in this video, “meaning we can share information on reef health in days rather than months or years.” As a coral reef ecologist based at the Australian Institute of Marine Science, Emma’s mission is to combine her expertise in coral monitoring with her passion for storytelling and photography to unite people around action on climate change.
