A caisson gate is a barrier used to dam off the open end of a dry dock and is constructed of heavy gauge steel with several tons of ballast in the keel. This deployment is sponsored by The Sportfishing Fund, an organization dedicated to artificial reef building.

Once the structure is fully flooded, it will have no more reason to remain upright and will likely fall over flat.

Spider Crab

Spider Crabs Libinia emarginata are scavengers. Although they are fearsome-looking, they are actually slow-moving, and their usual claws-out threat display is mostly bluff. Spider Crabs have relatively small round bodies (to 4"), long legs, and rather weak claws. They are found subtidally to at least 160 ft, on any type of bottom, and are very common in rivers and inlets. They often cover themselves with detritus for camouflage, and can also burrow in soft sediments.
