The deep waters of the oceans still conceal a lot of the unknown. Studies of the life of the inhabitants of the sea depths have been impossible for a long time because of the pressure drop during the ascent. When immersed in ocean depths, the water pressure increases by about 1 atmosphere for every 10 m. Thus, at the deepest point of the World Ocean it is close to 1100 atmospheres. For this reason, studies of the life of the inhabitants of the sea depths were very difficult and even impossible, since when they ascended to the surface they did not withstand a pressure drop.
This problem was solved with the help of special cameras, which help to adapt the deep-sea “inhabitants” to atmospheric pressure. Specialists from the Department of Ichthyology of the Academy of Sciences of San Francisco (USA) made dozens of dives to deep coral reefs located at a depth of 100-150 m off the coast of the Philippines, the islands of Vanuatu, Palau and Pohnpei. They managed to find 170 individuals of previously unknown species, more than 90% of fish survived the ascent with the use of special devices that regulate the water pressure inside deep-water vehicles.
In the near future, fish will be moved to a special aquarium in California, where they will be studied by ichthyologists.
