Small fish swim near white, bleached table coral in clear sea water

Dying Coral in Blue Seas.

This underwater video clip shows a large, bleached table coral with branches spreading widely, creating a fan-like shape against the blue background of the sea. Surrounding this white coral are small, colorful fish moving around, exploring the crevices and spaces within the coral's structure. The fish add life and color to the shot, while the clear water enhances the visibility, and shows coral textures and fish’s details as they swim. Other types of corals are visible nearby, though this particular table coral stands out due to its extensive bleaching.

Free Stock Footage of The Dying Reefs of Our Marine Worlds.

Filmed in ultra-high-definition 4K and available in HD (1080p), this footage was recorded with professional-quality equipment by experienced scuba divers. Available as free stock footage to support coral conservation awareness, it is offered in both landscape (16:9) and vertical (9:16) formats, suitable for social media platforms like Instagram Reels, Facebook, TikTok, and YouTube Shorts. This adaptability makes it ideal for environmental campaigns, NGO projects, documentaries, and educational materials on coral preservation and climate resilience.

Forecasting future bleaching events is essential as climate change drives increasingly frequent and severe marine heat waves. Programs like NOAA’s Coral Reef Watch use real-time satellite monitoring and heat stress models to predict where bleaching is likely to occur in the coming months. These models integrate data from satellite observations and climate projections to create detailed maps, allowing researchers to anticipate high-risk periods and identify areas that need immediate conservation action. For example, NOAA’s heat stress alerts can predict bleaching up to four months ahead, offering valuable time for implementing protective measures such as limiting human activities around vulnerable reefs to reduce additional stress.
