In an effort to help address the decline of coral reefs around the world, Australian designer Alex Goad of Reef Design Lab has created MARS (Modular Artificial Reef Structure), a modular system for building artificial reefs. Inspired by the modular building blocks of LEGO, MARS consists of ceramic modules that can be fitted together to form structures of varying sizes and configurations. The open design of the modules allows marine life to take refuge within, while the textured ceramic exterior is an ideal anchoring surface for coral. The MARS system has already been the subject of small scale trials in the coastal waters of Australia as well as in aquariums. Goad hopes to run larger scale trial, with 20 or more MARS modules, in the near future.
