He covered the distance between the Super Stallion and the gas station quickly, and soon found himself hovering in front of the ghostlike submerged structure.

Another design concept for a mostly submerged structure is The Gyre, which would stretch 400 meters deep and over a kilometer across.

Its dense growth tends to block condenser pipes and encrusts other submerged structures.

Applying a low voltage electrical current (completely safe for swimmers and marine life) to a submerged conductive structure causes dissolved minerals in seawater to precipitate and adhere to that structure.

The flooded Monte Ne has become a site of interest for scuba divers who dive by the amphitheater to get a look at the submerged structure.

Sonar images suggested to be a complex of submerged structures or a Cuban underwater city were recorded off the coast of the Guanahacabibes peninsula near the Pinar del Río Province in 2001.

Throughout the last decade new, submerged structures continued to be discovered in the waters off neighboring islands, trailing as far south as Taiwan.

If a submerged structure is used, the cost of the submerged chamber could represent up to 40 percent of the plant cost due to the strength and volume required.
