Living in ambient pressure habitats is a form of saturation diving, and return to the surface will require appropriate decompression. Closed to the sea by hatches, with internal air pressure less than ambient pressure and at or closer to atmospheric pressure; entry or exit to the sea requires passing through hatches and an airlock ...
Marine life, sea life or ocean life is the collective ecological communities that encompass all aquatic animals, plants, algae, fungi, protists, single-celled microorganisms and associated viruses living in the saline water of marine habitats, either the sea water of marginal seas and oceans, or the brackish water of coastal wetlands, lagoons ...
The residents of Goliath, who have invented some technologies to help them survive, some not even known to the outside modern world, live in a superficially utopian society under the autocratic leadership of John McKenzie (Christopher Lee), a junior officer at the time of the sinking credited with saving a sizable number of passengers and crew.

Marine biology is the scientific study of the biology of marine life, organisms that inhabit the sea.Given that in biology many phyla, families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy.
Marine life depends in some way on the saltwater that is in the sea (the term marine comes from the Latin mare, meaning sea or ocean). A habitat is an ecological or environmental area inhabited by one or more living species . [ 1 ]
From shallow waters to the deep sea, the open ocean to rivers and lakes, numerous terrestrial and marine species depend on the surface ecosystem and the organisms found there. [28] The ocean's surface acts like a skin between the atmosphere above and the water below, and harbours an ecosystem unique to this environment.

The ocean's surface has unique chemical and physical properties that may concentrate species specifically adapted to these conditions. For example, bacterioneuston living in the sea surface microlayer are often brightly coloured, [30] possibly as protection against solar radiation.
