We developed and tested a high-pressure optical chamber system for cultivation and microscopic observation of deep-sea organisms. The system is composed of an optical chamber, a highpressure pump, a pressure sensor and a microscope. The chamber has an observation cavity, 2 cultivation cavities and 2 sapphire windows. The pump is employed for perfusion of culture medium and for increasing the pr...
