Underwater habitats are underwater structures in which people can live for extended periods and carry out most of the basic human functions of a 24-hour day, such as working, resting, eating, attending to personal hygiene, and sleeping.
1 Δεκ 2023 · The technology will allow people to live at depths of up to 200m (656 ft) for up to 28 days at a time – revolutionising the way scientists observe, monitor and understand the oceans.
Organisms living in the deep ocean must be adapted to survive under extreme pressure, limited light, cold temperatures, and other factors.
A 60,000 km underwater mountain range stretches around our planet, formed as the plates that make up the Earth’s crust move against, or apart from, each other. In these areas, seawater seeps into cracks in the seafloor, heating up as it meets molten rock beneath the crust and then rising again to gush out of seafloor openings.
Climate change, ocean acidification, habitat destruction, pollution and overfishing are endangering the ocean and threatening its value and the security and livelihood of the three billion people who depend on it.
An underwater environment is a environment of, and immersed in, liquid water in a natural or artificial feature (called a body of water), such as an ocean, sea, lake, pond, reservoir, river, canal, or aquifer. Some characteristics of the underwater environment are universal, but many depend on the local situation.
What are the main obstacles to living underwater? Breathing is an obvious issue. Oxygen will have to be supplied from the surface, and underwater citizens will also need access to fresh water, food and power. One of the most ambitious habitats to be proposed so far is Japanese architectural firm Shimizu Corporation’s ‘Ocean Spiral’.
