Scubatlon Environmental Protection as a Sport Text and photos by Andrey Alexandrov 34 X-RAY MAG : 88 : 2018 EDITORIAL FEATURESTranslated TRAVEL by Andrey NEWS Bizyukin WRECKS EQUIPMENT BOOKS SCIENCE & ECOLOGY TECH EDUCATION PROFILES PHOTO & VIDEO PORTFOLIO feature Scubatlon Over the last half century, scuba diving—which was, in its ear- lier days, reserved for the elite, brave and courageous—has become a mainstream sport for the masses. On the one hand, this is very good. Millions of peo- ple get to see with their own eyes how diverse and excit- ing the underwater world is. On the other hand, diving causes serious damage to coral reefs, which are rich in biodiversity, but extremely vulnerable to human impact. In a response to the div- ing community’s demand for more protection of the reefs and the underwater realm, a group of divers came up with the idea of Scubatlon—a tournament in tra- ditional recreational diving with a conservation bent. How it all started but a quite down-to-earth person. The project that demand.

Scuba Diving: Self-Contained Underwater Breathing Apparatus
Scuba Diving: Self-Contained Underwater Breathing Apparatus SCUBA diving is likely to be the sport most frequently encountered in underwriting. Experience, type of diving, fitness level, medical impairments, lifestyle, and psychological/emotional maturity impact the overall risk. Certification level and participation in a nationally affiliated diving organization (YMCA, NAUI, NASDS, PADI, SSI) are considered as well. Borrowed or rented equipment may present an added risk to the diver because of unfamiliarity with use and/or the potential for failure. Depth of dives, sites frequented, and specialty certifications help define the nature and purpose of the diving done. Dives in open water represent less risk than technical diving (wreck, cave, and ice diving). Generally, the sport is safe if the diving is within the scope of the diver’s training. The greatest risk is presented by the inexperienced/unqualified diver who dives beyond his/her training and experience. Physical conditioning and a client’s health status are important to safe diving and impact the overall mortality risk. Some impairments are of particular concern to underwriting a diver. These include asthma, seizures, cerebral vascular accidents, diabetes mellitus, panic disorders, drug and/or alcohol abuse, coronary artery disease, and restrictive pulmonary disease. Caution is indicated when an individual is rated for a medical condition (especially those cited above) and he/she continues to dive. In general, a minimum of an Occupational Class 1 for diving is applied, regardless of the nature of the diving, in addition to any rating required for the medical history. A ratable driving record also poses an increased risk when combined with scuba diving.

I. Abstract Our Future Technology Vision Is to Go Scuba Diving Without the Tank. the Underwater Breather Will Last for As Long
I. Abstract Our future technology vision is to go scuba diving without the tank. The underwater breather will last for as long as you want to go because it filters the oxygen out of the water so you could go one day straight. It will also be able to detect and identify dangerous animals that can hurt you, and it will notify a lifeguard if you are in danger. II. Description 1. Present Technology Some equipment that exists today to breath underwater is scuba equipment which includes a scuba mask, oxygen tank and regulator, as shown below in the picture. There are lots of limitations to the standard scuba equipment such as the tank being heavy, having a limited amount of air, you could also run out of air under water, and you would have to fill the tank up multiple times so we are trying to find a way for the underwater breather to go deeper than any other scuba masks. The Exolong is a way to breathe underwater by taking air from the surface and using your legs to power the device however, the limitations to this device is that you have to be in shallow waters and you can't go deep diving with it. 2. History In 1942 during the German occupation of France, Jacques-Yves Cousteau and Emile Gagnen designed the first successful open-circuit scuba, a double hose system called the Aqua-Lung. Their system combined an improved demand regulator with high-pressure air tanks. This was patented in 1945. Before this you could either hold their breath or snorkel made out of a hollow reed.

Some activities lend themselves more readily to these objectives than others. Marine based tourism is one of them, and in particular recreational diving, one of the world‘s fastest growing sports. The Westfjords of Iceland, with its unique coastline, rich biota and long maritime heritage, appears to have all the potential to be an excellent diving destination.
