1962 in September, in the Mediterranean, a diver lived in an underwater house several meters deep for 24 hours, setting a precedent for human beings to live under the sea?

In the United States, the former Soviet Union and other developed countries, there are already experimental stations that can live underwater, but they are relatively shallow. 1962 In September, Edwin Link, USA established an underwater laboratory in the Mediterranean Sea near Toulon, France. A diver lived in a 60-meter-deep underwater house for 24 hours.

1988, the National Oceanic and Atmospheric Administration of the United States established another underwater laboratory in the waters of the Virgin Islands, with a length of 13. 1 m and a width of 3.7 m.. It is 5 meters high and weighs 8 1 ton, but it can only work on the seabed with a water depth of 15 meters. Six scientists can live in the laboratory and work on the seabed for 7-30 days. The laboratory is connected to the unmanned support ship on the water through the umbilical cord system. When the power supply or gas supply system fails, the underwater laboratory can rely on its own emergency system to maintain its work for 72 hours. Making room

Scientists have time to decompress and swim out of the water.

1977, the former Soviet union also built a benthic laboratory named "Benthic Organism 300", which can be used by 12 private crew at a depth of 300 meters 15 days.

Water bomb. The laboratory usually consists of a water supply ship, a crew transport cabin and an underwater laboratory I to ensure the life of the experimenters and access to the sea. The establishment of saliva experiment only has the significance of multiple forces: for example, it can approach the research object, conduct fixed-point qualitative research and observation at work and on site, and can observe for several days or even days continuously, which is comparable to other underwater observation methods (such as divers' observation in the sea). In addition, the establishment of water experiment psychic can provide scientific basis for human migration to the ocean in the future. With the increase of the earth's population, less than 30% of the earth's land is becoming more and more crowded. Although it is possible to immigrate to Mars and the moon, it is far away after all. Therefore, some countries with long coastlines and high population density have an increasing desire to migrate to the ocean. But before going to the ocean, we must have a deeper and more comprehensive understanding of the ocean, which can only be solved by underwater laboratories.

At present, few people can engage in ocean observation in underwater laboratories. Most people can only look at the ocean and sigh. They didn't appreciate the wonders of the ocean. But most people have a sense of exploration and curiosity, and are always willing to see with their own eyes what the depths of the ocean are like.

In order to satisfy these people's wishes, the Canadian Seabed Development Corporation built an undersea Atlantis for underwater sightseeing in 1990, which can carry 46 tourists at a time. It can spin at the speed of 15 nautical miles per hour at the seabed with a water depth of about 20 meters. Visitors can browse the strange world under the sea through the porthole on the submarine.
