Moon Pool Elevators

As a sort of evolution of caisson ship locks, moon pool elevators are special multi-tiered moon pools that behaves like a caisson ship lock, using hyperbaric pressure of neon-oxygen breathing gas to push the seawater down, and reducing that pressure to allow seawater to rise in an elevator shaft.

To make this economical, this shaft should be big enough that several shipping barges to fit in one elevator ride. Why shipping barges and navigable canals underground and underwater? it's surprisingly convenient and just plain cool. Shipping barges from the surface can enter and exit a long elevator shaft that terminates at the surface in an artificial island cove. The cove is shrouded in mist, produced by liquified air and chunks of dry ice from dry ice machines, and protected by very powerful superconducting magnets in frequencies designed to jam common communications channels, including aviation and nautical communications and navigation. This is a protective measure against potential invasion or military raid. These powerful magnets could also be used to flux pin islands in place for purposes of communications using free electron xray lasers and xray flat panel detectors, as well as additional defenses providing complex hazards for aircraft.

Using this technology, you could artificially cause the surrounding atmosphere to cool and precipitate out all water vapor and form a permanent shroud of clouds and rain, which wrecks havok with many types of communication, including military communications. A light spray of seawater, such as with artificial geysers, can provide the condensation nuclei necessary for water vapor to condense into rain. These artificial geysers could be powered by the molten salt, and fog machines powered by the liquid neon.

To access the cove, you have to navigate a series of obstacles, and then manually activate one of six elevators, which are hidden in a secret harbor within the cove. The harbors have counterweighted locks which seal the enclosure and pressurize the chamber until the seawater begins to receded. This receding seawater level is part of a system of moon pools, and draws the vessel deep underwater, which then can travel along a network of underwater canals.

During the descent, the neon-oxygen atmosphere is traded for the natural atmosphere, so that as pressure increases the nitrogen is removed, and as the pressure decreases, nitrogen is slowly added. This is both to protect the vessel's occupants as well as to conserve expensive neon gas.
