Reef CCA - SMS Warehouse Barge

Reef CCA — SMS Warehouse Barge is an intermediate artificial reef site in Georgia's Atlantic offshore waters, where a decommissioned warehouse barge has been deliberately sunk to create marine habitat within the state's comprehensive Coastal Communities Artificial Reef program. The distinctive warehouse barge configuration — an enclosed hold designed for cargo storage rather than open deck transport — creates a reef structure with particularly interesting internal spaces that marine life has colonized to create an unusually productive enclosed-habitat diving experience. Warehouse barges, with their enclosed cargo holds, provide a different reef configuration from open-deck barges or conventional ship wrecks. The enclosed hold, once the barge settles on the seafloor and marine organisms begin their colonization, becomes a darkened interior space where shade-adapted species thrive and where the transition from open water to overhead environment creates the kind of light effects that photographers find particularly compelling. The roof of the hold provides the overhead structure that creates these dramatic lighting conditions, while the openings that provide diver access also allow natural light to filter in and create the shaft-of-light effects that make enclosed-reef photography so distinctive. Marine colonization within the SMS Warehouse Barge's hold has created an interior environment of considerable biological interest. The reduced light favors sponges and other non-photosynthetic encrusting organisms, and the shelter creates conditions where species that cannot compete in the more exposed outer surfaces of the reef can establish thriving populations. Lobster, moray eels, and other denizens of sheltered spaces make the hold their home, and schools of sweepers and other shade-loving fish create the living curtains of movement that interior wreck spaces are famous for. The outer surfaces of the barge provide the conventional artificial reef experience of encrusted hull surfaces, schooling fish populations, and the various reef species that use the exterior structure as territory. The combination of interior and exterior diving environments within a single structure provides the variety that makes this and similar reef CCA sites more interesting than simpler artificial reef deployments. Reef CCA's SMS Warehouse Barge demonstrates the ecological and recreational value of thoughtful artificial reef design in creating diverse underwater habitats along Georgia's sandy Atlantic coast.
