Some snorkels have a sump at the lowest point to allow a small volume of water to remain in the snorkel without being inhaled when the snorkeler breathes. Some also have a non-return valve in the sump, to drain water in the tube when the diver exhales. The water is pushed out through the valve when the tube is blocked by water and the exhalation pressure exceeds the water pressure on the outside of the valve. This is almost exactly the mechanism of blast clearing which does not require the valve, but the pressure required is marginally less, and effective blast clearing requires a higher flow rate. The full face mask has a double airflow valve which allows breathing through the nose in addition to the mouth. A few models of snorkel have float-operated valves attached to the top end of the tube to keep water out when a wave passes, but these cause problems when diving as the snorkel must then be equalized during descent, using part of the diver's inhaled air supply. Some recent designs have a splash deflector on the top end that reduces entry of any water that splashes over the top end of the tube, thereby keeping it relatively free from water.
To date, all national and international standards on snorkels specify two ranges of tube dimensions to meet the health and safety needs of their end-users, whether young or old, short or tall, with low or high lung capacity (See Figure 1 and Figure 2). The snorkel dimensions at issue are the total length, the inner diameter and/or the inner volume of the tube. The specifications of the standardisation bodies are tabulated below.
Sports journalism expert Kimberly Bissell conducted a study on the camera angles used during the 2004 Summer Olympic Games beach volleyball games. Bissell found that 20% of the camera angles were focused on the women's chests, and 17% on their buttocks. Bissell theorized that the appearance of the players draws fans attention more than their actual athleticism. Sports commentator Jeanne Moos commented, "Beach volleyball has now joined go-go girl dancing as perhaps the only two professions where a bikini is the required uniform." British Olympian Denise Johns argues that the regulation uniform is intended to be "sexy" and to attract attention. Rubén Acosta, president of the FIVB, says that it makes the game more appealing to spectators.
“[L]andscapes are cultures before they are nature—constructs of the imagination projected onto wood and water and rock,” Simon Schama wrote in 1995. In 2019, the quote appeared in the introduction to John Berger’s Landscapes, which I’d finally found time to read in a zero-gravity lounge chair overlooking the sea. But it wasn’t just any sea. The water was really water but not the salty kind, instead of a sandy bottom there was stainless steel flooring and, from the horizon, a gigantic canvas screen-printed with a photo of a blue sky rose up. Outside the dome, the sun had broken through clouds; inside, it filtered through a UV screen. I applied more sunscreen to my face. I considered taking a dip.
Northern California beaches. They tend to be cold and windy, and Ocean Beach is no exception. There are those glorious warm days that happen a few times per year in the Fall. If you choose this location for a photo shoot make sure that you wear layers at this location. And arm yourself with hair ties and clips, because it can get windy. Take it from me, a family photographer (K. Sienk Photography)!
Raquel Welch's fur bikini in One Million Years B.C. (1966) gave the world the most iconic bikini shot of all time and the poster image became an iconic moment in cinema history. Her deer skin bikini in One Million Years B.C., advertised as "mankind's first bikini", (1966) was later described as a "definitive look of the 1960s". Her role wearing the leather bikini raised Welch to a fashion icon and the photo of her in the bikini became a best-selling pinup poster.
