In the 21st century, tropical corals are experiencing unprecedented stress through global warming, as 1°C above the annual thermal maximum causes the breakdown of symbiosis with their algal symbiotic partner. This phenomenon is also known as coral bleaching because of visual change to a stark white appearance. When a coral is bleached, it cannot receive any photosynthetically derived nutrients, therefore is in a low energetic state and vulnerable to death. 

Zhang and Wong created a piece to visualize giving the color back to the bleached corals, showcasing the lost but also presenting the hope for future corals. This interactive piece allows the viewer to understand that symbioses, environmental conditions, and proper actions taken by humans are key in maintaining coral reefs against climate change. 

ABOUT THE COLLABORATIVE VISUALIZATION GRANT

The Collaborative Visualization Grant is open to all former Vis-a-thon participants and is intended to help develop projects further, and promote interdisciplinary partnerships.
