Artificial Reefs
What are Artificial Reefs? An artificial reef is a human-made underwater structure that substitutes as a natural reef to form a habitat for marine life. Artificial reefs are placed in areas where there is little bottom topography or near coral reefs to attract marine populations.
Why Artificial Reefs? Artificial reefs serve to protect coral reefs form human-induced damages. In addition, they are used for mitigating coastal erosion, creating surf breaks, and in the past have been built to block ships from entering coastal waters.
