A module for an artificial reef is substantially in the shape of a continuous arch and is formed as a skeletal framework comprising a plurality of spaced apart transverse beams that each define a portion of the arch, and a plurality of longitudinal beams attached to the transverse beams and extending the length of the arch. The longitudinal beams provide a barrier to waves when one or more modules are anchored to the sea floor. The module is additionally usable as an electrified reef to accelerate mineral deposits on the beams that encourages marine life and increases the effectiveness of the wave barrier.

Disclosed is an artificial reef molded from a mixture of environmentally friendly homogenized organic and inorganic materials, cement, and 5 aggregates of sand and gravel to form thereon an artificial reef such as reef buds, reef plates, reef honeycombs and other reef structures.

The present invention relates to a removable artificial reef and barrier system capable of mitigating detrimental wave and current energy and erosion problems, enhancing biological growth and marine aquaculture, increasing carbon sequestration, providing power generation, and enhancing favorable surf conditions for recreational use.

A breakwater comprising a base member having an outer surface, and a plurality of elongate members is disclosed. An end region of each of the plurality of elongate members is coupled to the outer surface of the base member. The base member and/or at least one of the elongate members has a textured surface for the attachment of marine life. The breakwater may be located on a seabed, a riverbed, an ocean floor or a floor of a waterway, to protect a coast or riverbank from coastal erosion.

The present invention relates to a removable artificial reef and barrier system capable of mitigating detrimental wave and current energy and erosion problems, enhancing biological growth and marine aquaculture, increasing carbon sequestration, providing power generation, and enhancing favorable surf conditions for recreational use.

A sunscreen is disclosed that promotes ocean health, especially for coral reefs. The sunscreen includes an active sunscreen component, a delivery component, and one or more alkalinity enhancing components. The sunscreen component filters or blocks some amount of harmful solar radiation from affecting the wearer's skin and is preferably reef-safe and free from ingredients that pose health risks to wearers. The alkalinity enhancing components counteracts ocean acidification, or raises the pH, of the local environment, e.g., in the vicinity of reefs. The delivery components facilitate application of the active sunscreen component to the wearer's skin such that the active sunscreen component is distributed across a protected area of the wearer's skin in an effective coverage amount. The sunscreen assists in coral reef recovery, as well as improving other ocean environments, and thereby promotes ocean health.

A concrete wave attenuating apparatus facilitating the formation of a vertical oyster reef includes: A) A concrete wave attenuating frame having i) a concrete frame top and a concrete frame bottom defining a periphery of the frame, each having corners and sides extending between the corners, ii) concrete corner posts extending generally vertically between generally aligned corners of the concrete frame top and the concrete fame bottom, iii) concrete sides between the concrete corner posts extending generally vertically between the generally aligned sides of the of the concrete frame top and the concrete fame bottom, a plurality of passages extending through the concrete sides; B) A space defined within the concrete wave attenuating frame, wherein the plurality of passages extend to the space; and C) optionally Cultch material within the space.

An apparatus and method for coral husbandry including a frame configured to attach to an aquaculture raceway, a carriage having a plurality of tools mounted thereon, the carriage being attached to the frame and configured to move relative to the frame, the plurality of tools comprising a rotary tool having a tool member attached thereto, a nozzle configured for at least one-way fluid communication, and an inspection instrument for monitoring and cataloguing coral reef specimens.

The present invention relates to a removable artificial reef and barrier system capable of mitigating detrimental wave and current energy and erosion problems, enhancing biological growth and marine aquaculture, increasing carbon sequestration, providing power generation, and enhancing favorable surf conditions for recreational use.

There is described a module for an underwater structure. The module comprises a plurality of walls defining a cavity configured such that at least two walls of said plurality of walls confront one another to provide respective stack support surfaces for supporting said module, said walls are substantially parallel to form complementary stack surfaces, such that one stack surface may rest on a surface and the other complementary stack surface provides a rest surface for another module. Two or more walls of said plurality of walls each comprise an aperture providing a conduit through each two or more walls to said cavity, respective apertures of said two or more walls and said cavity configured to provide a water flow path into, through and from said cavity. The water flow path may be considered unconstrained or at least substantially unconstrained in that water ma flow through the apertures and cavity without deviation or interruption other than by the module or cavity walls. In stacked formation an aperture may be occluded or partially occluded but still the module when on its own may provide water pathways which may be considered unconstrained or substantially unconstrained.
