November’s Coral Restoration Full Certificate – A Month of Learning, Diving, and Restoring Hope Underwater
November 2025 became a month filled with stories for the five participants who gathered in Bali for the Coral Reef Restoration Full Certificate—a four-week learning journey that not only deepened their scientific understanding, but also strengthened their connection to the ocean and to one another as reef guardians, combining classroom theory with hands-on practice in the ocean. The three scholarship recipients—Disya Shafa Azizah, Lusiana (Blue Forest), and Daniel Jackson Jay (Trilogy Ocean Restoration, Karimun Jawa)—joined with strong motivation to expand their capabilities as restorers. They were accompanied by two self-funded participants from abroad, Mohammad Alkhonaini (Kuwait) and GP Villoresi (Italy), bringing valuable global perspectives to the experience. The first two weeks in Mero Foundation, Tulamben focused on coral morphology, genus-level identification, learning to observe coral characteristics and identify each genus through a combination of classroom discussions and daily underwater practice. As they moved into coral gardening, the learning became more hands-on: cleaning algae, removing Drupella, and planting new coral fragments

When Mooring Buoys Become a Threat to the Corals We Protect
Corals – The Hidden Foundation of Marine Life In Nusa Penida, tens of thousand of visitors visit Manta Point in Nusa Penida, Bali. But behind every manta ray, mola mola, or school of reef fish lies a hidden truth: without coral reefs, none of these creatures could survive. Coral reefs provide homes to the baby fish to hide from predators, or host the species that these iconic species feed on. Ocean Gardener has been working with the local fishermen community, Nuansa Pulau. Together, we have been planting over 200,000 corals at the Ped restoration site in Nusa Penida alone. Our work is not just about conservation and restoration, it’s also about strengthening the pivot to the eco-tourism economy through snorkeling, freediving and diving. By working with the local fishermen community to replant the reefs, we have fostered a huge sense of pride and ownership. Healthy coral reefs are the true foundation of Nusa Penida’s identity.

Impressive results after 2 weeks of running our Mineral Accretion Technology pilot
We revisited our first Mineral Accretion Technology (MAT) after 2 weeks to monitor its progress. You can read our previous blog post about the MAT system installation. It goes through the installation process and technical details of our pilot site in front of our partners, the MERO Foundation, in Tulamben, East Bali. It took many years to convince us to try Mineral Accretion Technology (MAT). Like many, we had been disappointed with the published results achieved by various organizations using this technique in their own projects. Nevertheless, being stubborn, we preferred to see for ourselves what this technique offered and if it could be a viable tool for coral restoration. Ring Layout Of Coral Tables and Reef stars The idea was to have a homogeneous inner ring of tables and an outer ring of Reef Stars around the Anode. Every structure of the same size is placed at the same distance from the Anode as the others, thereby receiving exactly
