Restoring Coral Reefs in Bali

On this expedition, you won't just observe the challenges facing coral reefs worldwide-you'll actively contribute to conservation efforts.

Despite its rich underwater life, many of Bali's reefs have been severely damaged by destructive fishing practices, warming ocean temperatures, and pollution. The loss of healthy reefs threatens marine biodiversity and the livelihoods of coastal communities that depend on them for fishing and tourism.

Could artificial reefs offer a solution by mimicking natural coral communities? Scientists in Bali are exploring whether artificial reefs can preserve biodiversity and support resilience against climate change. Unlike natural reef ecosystems, which can take thousands of years to mature, artificial reefs can be made and deployed quickly.

Join Earthwatch scientists in the Balinese fishing community of Tianyar, where 45,000 artificial reef structures have already been installed. Surround yourself with corals, sponges, fish, turtles, and rays as you help scientists collect data. You'll snorkel or scuba dive* in a locally established Marine Protected Area over natural and artificial coral reefs.

With robust data on the benefits of these structures, the Indonesian government and governments globally will be better equipped to protect marine biodiversity and safeguard the livelihoods of coastal communities.

Join this expedition to contribute to cutting-edge reef restoration science while exploring one of the world's most breathtaking marine environments. Your work will help protect marine biodiversity and support the communities that depend on healthy reefs for generations to come.
