Scuba diving is one of the most popular “water sports” with its worldwide popularity constantly on the rise. And while you should gain the necessary basic knowledge during your PADI Curse Open Water Diver, here are 10 interesting facts the books most probably won’t mention.
• SCUBA stands for “Self contained underwater breathing apparatus”
• The modern wetsuit was invented by the American physicist, Hugh Brandner, in 1952. One of the first (and very successful) wetsuit manufacturers was O’Neill.
• If you spit in your dive mask prior to the dive, as gross as it may be, it will actually prevent the mask from fogging. This is because the spit will coat the lens and the layer will be too smooth for the condensed vapor to hold on to. If you don’t want to spit, the soap or detergent will do the same trick.
• Every year over 70 unprovoked shark attacks are reported worldwide.
• Sharks have unfairly gained a bad reputation thanks to the horror movie Jaws (1975). However far more people are killed by the lightning in the US, than by sharks.
• Oxygen becomes toxic under high pressure. That is why special gases with lower concentration of oxygen are provided for dives deeper than 42m.
• Water absorbs light rapidly, that’s why scuba diving rookies might feel disappointed that the underwater world actually looks a little bit less colorful than in the TV documentaries. The color that is absorbed the quickest is red. Hence the red filters for the underwater cameras like GoPro and others. The color red is followed by orange, yellow, green and blue.
• If you think you are passionate about scuba diving, try to beat the Guiness world record of a Turkish scuba diver who managed to scuba dive in the open water for almost SIX DAYS!
• While official statistics of scuba diving injuries would mention barotraumatic injuries as the number one injury related to scuba diving, in reality broken fingers or broken noses are the most common ones. So think twice next time you float to close the boat ladder while another diver is trying to climb up or when carrying tanks and weights.
• Finding Nemo was without the doubt one of the most successful and memorable Pixar movie. And the art team didn’t leave anything to chance. To understand the underwater world better, they took scuba diving courses in oceanography, marine biology and more.
