Development of High Pressure Research Instrument for Keeping of Deep-Sea Multicellular Organisms
In this article, recompression induced resuscitation and atmospheric pressure acclimation of deep-sea multicellular organisms were investigated. Despite captured deep-sea organisms at depths between 910 m and 1,300 m sustain serious damage on decompression and exposure to high temperature of surface seawater, the organisms recovered by immediate re-compression until 5 MPa within 30 minutes after submersible bring back to mother ship. The re-pressurized deep-sea organisms can acclimatize at atmospheric pressure condition for a few months after slow decompression at a rate of −0.025 MPa/h. Furthermore, negative potential application induced antirust effect of pressure-stat aquarium system, which composed of stainless steel, was also described.
