- 1Scientists deploy underwater umbrellas to shield coral reefs●Scientists invent underwater umbrellas to protect coral reefs
Scientists have developed umbrella-like structures that can be placed underwater to protect coral reefs, and the approach appears to be working. The devices shield corals from stressors such as excessive light or heat, offering a novel low-tech tool in efforts to slow reef decline as ocean temperatures rise.
- 2Underwater umbrellas proposed to shield corals from heat●Could underwater umbrellas help corals survive hotter seas?
Scientists are exploring whether underwater umbrellas could shade coral reefs and help them survive increasingly hot seas. The idea is part of a broader push to develop ways to cool or shelter corals as rising ocean temperatures trigger mass bleaching events. The question of whether such shade structures can work at scale is now being debated.
