The coral species that build reefs are known as hermatypic, or "hard," corals because they extract calcium carbonate from seawater to create a hard, durable exoskeleton that protects their soft, sac-like bodies. Other species of corals that are not involved in reef building are known as “soft” corals.

Artificial reef module for coral reef remediation
InactiveUS6464429B2Aid in disseminationPromote reproductionBreakwatersQuaysEngineeringArtificial reef
The artificial reef module for coral reef remediation of the present invention includes a central body having an upper settling plate, a middle settling plate, and a lower settling plate. Extending from the central body is a plurality of primary tines which further include a plurality of secondary tines extending from them. The primary tines include the supporting tines, the stabilizing tines, and the space filling tines. The branching of the tines closely replicates the appearance of natural branching coral. Over time the individual artificial reef modules for coral reef remediation would slowly degrade and allow the tines to break off. This degradation closely approximates the fragmentation that occurs with natural branching coral.

Artificial reef anchor structure
A container for underwater placement on a sea, lake or river bottom. The container has openings in the sides, top and bottom and is filled with ballast of large boulders, cobble, crushed coral, cast concrete modules or other materials. The openings allow water and water currents, as well as marine organisms, to pass freely therethrough. Over time, a wide assortment of marine organisms infiltrate and colonize the nooks, crevices and cavities of the ballast, thus utilizing the habitat as they would an artificial reef. One or more hitch points are provided on the container for attaching mooring lines for ships, boats, floating wind turbines or other floating structures, thereby allowing the artificial reef to anchor such structures.
