Underwater Umbrellas Show Promise in Protecting Coral Reefs from Heat Damage

A new study published in Frontiers in Marine Science suggests that umbrella-like shades can offer temporary protection to vulnerable Caribbean corals against heat-related bleaching. While shading cannot cool the water, it prevents UV and irradiance damage, which exacerbates heat damage. The research found a significant positive impact on two highly-susceptible coral species, indicating its potential usefulness for other coral types.
