Can Concrete Molds Revive Coral Reefs Ruined by Bombs and Climate Change?

Restoring Coral Reefs in the Coral Triangle

In the Pacific Ocean’s Coral Triangle, a devastated area is witnessing efforts to rebuild its marine ecosystem. A conservation group has embarked on a project to create an artificial reef.

Robin Philippo, managing director of the Tropical Research and Conservation Center, leads the installation of these artificial structures near Pom Pom Island, Malaysia.

Challenges and Efforts

A small boat journeyed from a Western Pacific island to a nearby location, carrying concrete pieces each weighing 60 pounds. These textured structures mimic white lotus leaves.

As the crew unloaded the pieces, divers descended 20 feet to the seabed. Equipped with nuts, bolts, and steel rods, they assembled the concrete pieces. Hundreds of damsel fish and several green turtles observed as the work progressed.

In approximately an hour, the artificial reef was completed, standing 3 feet tall and 10 feet wide.

Technology and Techniques

The structures utilize 3-D printed molds designed from concrete.

Volunteers and conservationists work together, using lift bags to position the structures accurately on the seabed.
