Artifical Lagoon
The floating atoll is a circular breakwater of 16-20km (10-12 miles) diameter, surrounding a lagoon of calm water.
Like in many natural atolls, people live on small artificial islands, house boats, or floating tents, according to the taste and skills of the inhabitant.
The breakwater is built on a reserve of fresh water (approximately 3.5% lighter than seawater) in a floating container. The outer side (seaside) of the ring is covered by various types of emulated coastline structures to maximize the diversity of ecosystem. The lagoon side is covered by rich topsoil, various plants and cultivation.
The bottom of the lagoon is open to the deep sea, but protected from unwanted predators by a net. Many forms of mariculture are practiced in box and other systems hanging at different depths.
