Dive into a reef restoration adventure in Tianyar, a Balinese village home to one of Indonesia's largest artificial reefs. Spend your days swimming in the waters off a striking black sand beach, with the towering Mount Agung volcano as your backdrop. As you snorkel or scuba dive*, you'll monitor fish and coral, helping scientists assess the effectiveness of artificial reef structures in rebuilding marine ecosystems.

On this expedition, you won't just observe the challenges facing coral reefs worldwide—you'll actively contribute to conservation efforts. Bali sits within the Coral Triangle, the most biodiverse marine region on the planet. But despite its rich underwater life, many of the island'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. Reefs also perform critical ecosystem services like coastline protection and carbon cycling.

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 ÃÀ¼§ÉçÇø 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.

*Note: Certification is required for participation on scuba teams. See the online expedition briefing for details.

Note: A specialized visa, the C6B (Social-Cultural) Visa, is required for volunteering in Bali. ÃÀ¼§ÉçÇø has confirmed a facilitated process for volunteers to obtain this visa through an agent of our local partner organization. Details are provided upon registration in the Expedition Logistics Document. Volunteers are responsible for the cost of the visa, which is approximately $230 USD.
