Diving in scuba gear. The Aqualung, developed by ocean explorer Jacques-Yves Cousteau and others in 1943, became popular after its release in 1947, and it quickly became popular as a sport and leisure activity after World War II. Although a license is not legally required, because of the high risk of serious danger, a certification card (C-card) is often required to prove that one has completed a diving training program based on safety standards. In Japan, they are issued by various private educational organizations. Source: Encyclopaedia Britannica Concise Encyclopedia About Encyclopaedia Britannica Concise Encyclopedia Information |
スキューバを身に着けて行なう潜水。 1943年,海洋探検家のジャック・イブ・クストーらによって開発されたアクアラングが 1947年に発売されてから大衆化し,第2次世界大戦後にスポーツまたはレジャーとして急速に広く親しまれるようになった。免許は法的には不要だが,重大な危険を伴う可能性が高いため,安全基準に基づいた潜水技術教育プログラムを終了したことを証明する認定書 (Cカード Certification Card) が必要になる場合が多い。日本では各民間教育団体が発行している。
