Snorkels constitute respiratory dead space. When the user takes in a fresh breath, some of the previously exhaled air which remains in the snorkel is inhaled again, reducing the amount of fresh air in the inhaled volume, and increasing the risk of a buildup of carbon dioxide in the blood, which can result in hypercapnia. The greater the volume of the tube, and the smaller the tidal volume of breathing, the more this problem is exacerbated. A smaller diameter tube reduces the dead volume, but also increases resistance to airflow and so increases the work of breathing. Occasional exhalation through the nose while snorkeling will slightly reduce the buildup of carbon dioxide, and may help in keeping the mask clear of water. It may also increase fogging.
Diving while snorkeling requires that you learn to force your ears to “pop” to equalize pressure and swim below the surface more comfortable. You also need to practice expelling water from your snorkel by forcing a strong burst of air through the tube as you clear the water’s surface. Special “purge snorkels” are available on the market for those who want an extra line of protection against getting water in your mouth.
Continental islands are bodies of land that lie on the continental shelf of a continent.[10] Examples are Borneo, Java, Sumatra, Sakhalin, Taiwan and Hainan off Asia; New Guinea, Tasmania, and Kangaroo Island off Australia; Great Britain, Ireland, and Sicily off Europe; Greenland, Newfoundland, Long Island, and Sable Island off North America; and Barbados, the Falkland Islands, and Trinidad off South America.

After making sure your equipment works and fits, do a test run. Get used to breathing out of a snorkel. Swim around a pool if necessary. Get used to the feeling first. If you are in a beach, start by swimming around the shallow area before plunging into the deep. By practicing, you are getting yourself used to the feeling of swimming around and breathing through the snorkel. Remember to always keep the top of the snorkel afloat. If water comes in, you can easily blow the water out.

Just bought the Super Snorkel and brought it to Montauk last weekend. Boy was it a hit! Everyone wanted to try out the snorkel. We even had people who had been snorkeling for years there. They were blown away by the performance. It is amazing to be able to go underwater WITHOUT anything in your mouth. No more jaw tightness from calming on the snorkel mouthpiece. I can't wait to use it again on our next trip, or even at the pool.

1950: First use of "snorkel" to denote a breathing device for swimmers. In November 1950, the Honolulu Sporting Goods Co. introduces a "swim-pipe" resembling Kramarenko and Wilen’s side-mounted ball- and flutter-valve breathing tube design, urging children and adults to "try the human version of the submarine snorkel and be like a fish".[42] Every advertisement in the first issue of Skin Diver magazine in December 1951[43] uses the alternative spelling "snorkles" to denote swimmers’ breathing tubes. In 1955, Albert VanderKogel classes stand-alone breathing tubes and swim masks with integrated breathing tubes as "pipe snorkels" and "mask snorkels" respectively.[44] In 1957, the British Sub-Aqua Club journal features a lively debate about the standardisation of diving terms in general and the replacement of the existing British term "breathing tube" with the American term "snorkel" in particular.[45] The following year sees the première of the 1958 British thriller film The Snorkel, whose title references a diving mask topped with two built-in breathing tubes. To date, every national and international standard on snorkels uses the term "snorkel" exclusively.
