Deep sea diving is an underwater activity that allows individuals to explore the ocean's depths. Divers use specialized equipment, such as scuba gear, to breathe and navigate underwater. This activity can reveal diverse marine life, underwater landscapes, and shipwrecks, making it popular among adventurers and researchers alike. Safety is crucial in deep sea diving, as the pressure increases significantly with depth. Divers must be trained to manage risks like decompression sickness and equipment failure. Organizations like PADI (Professional Association of Diving Instructors) offer courses to teach proper techniques and safety measures for both recreational and professional divers.
