Coral reefs are a fundamental part of the world’s ecosystem; however, they are hidden in the ocean’s depths, which makes it difficult to see how they are affected by climate change. When under certain pressures, such as warmer temperatures, coral undergoes a process called bleaching. This causes coral to expel their algae, resulting in the loss of their energy source and vibrant colors. As climate change continues to intensify, the frequency and severity of coral bleaching events threaten the recovery and adaptation of coral species. The Great Barrier Reef, the world’s largest coral reef system off the east coast of Australia, has undergone aerial surveys and underwater assessments to measure the corals’ levels of heat stress and bleaching thresholds. Ultimately, the data reveals that increased heat stress leads to greater coral mortality. Similar to most species, some corals are more adaptive, while others are more vulnerable. Therefore, it is critical to understand the composition of each coral species and how they differ around regions of the world to determine what proactive measures should be taken to preserve the ocean’s ecosystems.

  1. Hi Anja and Noah!
    Coral bleaching is an important subject to bring awareness to! The ocean is one of the most amazing places on earth. It has many different aspects that make it amazing. I knew that the temperatures rising globally were not good for the ocean but didn’t know why. I am really glad I was able to view your presentation video and learn more about coral bleaching. One thing that Anja mentioned that I found very surprising was that corals have different resiliency levels. I did not know that when corals are put through extreme heat some die immediately, and some will end up dying over several bleaching events. I assumed all corals would die at the exact same time. One thing that Noah mentioned that I didn’t know was if the corals died off it would lead to a domino effect on the rest of marine life biodiversity. I really enjoyed learning the different ways that could help reduce the amount of coral bleaching. I think gene editing for corals is really smart. It makes sense to try to make every coral the strongest one. Thank you for presenting!! I enjoyed listening to and learning about coral bleaching.
