Beneath The Sea was a couple of weeks ago and I heard it was a great show. Unfortunately my Honey Do List has grown and I am trying to get it all done before the weekend dives pick up so I was not able to go. But I was thinking about it. Well this past winter continues to linger a bit longer. Dutch Springs had to delay their opening from April 5 to April 12 due to ice on the lake and then the need to fix some damage caused over the winter. I have had my first dive postponed as well because the boat is not ready to go due to the cold weather and repairs needed. I will have to be patient; the first dive is not April 26 to The Heroine. I can t wait for the season to officially start. For our April meeting we have Captain Bill Palmer doing a presentation on the Sinking of the SS Blackpoint. Which is the last ship torpedoed in WWII. She was attacked and sunk by the German Sub U-853 at 17:40 hours May 5, The United States retaliated and sunk the German Sub with depth charges...and so ended the Last Battle of the Atlantic. So come down early as there is usually standing room only when Capt. Palmer is in town. The April meeting on 25th and the Easter Egg Hunt/ Beach Clean-Up on April 27 th. Happily Blowing Bubbles.your entrusted, reluctant volunteer!!!! Matt waiting at Dutch Springs for the ice to melt!

4 Page 4 5 Tips to remember if you re left behind 1.Do a 360. If you come up and the boat is gone, turn a full circle, scanning the horizon for land, other boats or anything you could cling to. If safety is close, drop your weights to swim on the surface, but keep your mask and regulator/ snorkel intact.

Every diver should have a surface- marker buoy, a signal mirror and an audible signal that connects to your low -pressure inflator. Use the mirror and au- dible alert if you see someone. A better solution is to carry a GPS beacon like the Nautilus Lifeline. 3. Conserve energy. If you have to swim for shore against the current, don t swim directly into it. Fighting a current is a fast way to burn energy. If you must swim against the flow, go diagonally or perpendicular. 4. Stay warm. Even with a wetsuit, extended time in the water can sap your body of heat. You can conserve body heat by hugging your knees to your chest. 5. Keep calm, but prepare to fight. Not only can thrashing lead to drowning, it also alerts sharks. Take deep breaths, and make intentional movements and decisions. If the sharks show up, be prepared to defend yourself by punching.

5 Page 5 Breathing Underwater: 8 Tips to Save Air When Diving by Jim Bartlett What It s like to Get Bent by Jill Heinerth 1. Stay Warm If you dive uninsulated, you re heating the ocean with your body, which increases your metabolism and oxygen-burn rates. Experiment with different amounts of protection. 2. Go Slowly Rapid, jerky movements burn more air due to increased resistance underwater. 3. Look, Ma, No Arms! Imagine you re a Tyrannosaurus rex, with huge legs and tiny little arms. Waving your arms and hands around burns incremental air, with little or no impact on your position. 4. Trim Up Poor weight distribution created increased drag and burns more air. (Ditto for gear that drags.) Try varying weight positions. 5. How Slow is Slow? Try using time as a guide. Inhale over a five- to seven-second period, and exhale over a six- to eight-second period. As a slower rate becomes more natural, you ll no longer need to count. 6. Reverse the Pause Pausing at the top of our inhalation cycle instead of at the bottom, as we do on land allows our bodies to extract a bit more oxygen from the air in our lungs. Practice in a swimming pool. 7. Restrict the Flow Try this: Hold your tongue against the roof of your mouth and breathe around the sides of your tongue. This artificially created restriction will force you to breathe in more slowly. 8. Practice As with any sport, performance improvements come with practice. Reprinted from Scuba Diving Good judgment comes from experience. Yet experience often arises as a result of bad judgment. More than a decade ago, I earned a lot of experience when Paul Heinerth and I eagerly hiked into the Yucatan to explore the Pit, a cave system we had uncovered three years earlier. Armed with newly developed rebreathers and precious helium mixes, we would be diving nearly 400 feet deep. Today, the Pit is easily accessible by jungle road, but in the earliest exploration of the Sistema Dos Ojos, getting gear to the site required exhausting hikes, makeshift donkey carts, robust Maya sherpas, and a lot of determination and sweat. Paul and I had anticipated the help of a local support team, but on arrival, we discovered that they had been dispatched to assist the thriving recreational tourism business. I was a little perturbed but resolved that we could do it on our own. We had plenty of equipment, supplies and a trusty Comex In- Water Recompression Table. Our logbooks were fat with many thousands of dives, and perhaps I was feeling a little invincible. Some combination of passion and spirit led me to dive to almost 400 feet two days in a row, something I had not done before and have not done since that punishing day. Feeling marching ants crawling under the skin of my thighs at 60 feet during decompression, it was clear to me that I was bent. It (Continued on page 7)

6 Page 6 Shark of the Month: Thresher Sharks by David Shiffman It s easy to identify thresher sharks by their extremely long tail, which can be as long as the rest of their body. Despite their relatively large size, thresher sharks eat mostly small fish, but have also been known to eat squid and other invertebrates. Divers rarely see the common thresher, but those who have encountered them report that they are harmless, shy and hard to approach. A few species of threshers are some of the few sharks that are endothermic, meaning that they can regulate their body temperature using modified muscles and blood vessels along their flanks and near their eyes. Threshers are also sometimes referred to as fox sharks." Interesting Facts:» Threshers have been measured whipping their tails at almost 80 miles per hour.» There are two other species of thresher shark, the bigeye thresher (Alopias superciliosus) and the pelagic thresher (Alopias pelagicus). The IUCN Red List considers all Vulnerable to Extinction. They are one of the few species of sharks targeted for their meat, and they are also commonly caught as bycatch. The U.S. thresher fishery is generally considered to be well managed, but many international fisheries for thresher sharks are not.» Despite their large size, thresher sharks have relatively small litters of two to seven pups. They are viviparous, which means they give live birth, and thresher pups can be more than 3 feet long when born.

7 Page 7 What It s like to Get Bent by Jill Heinerth (continued) (Continued from page 5) came on slowly at first, but soon I had the urge to scratch through all the layers of trilaminate and undergarments that were keeping me warm and dry. I had never felt a sensation like that. A growing ache in my shoulder made my situation even harder to ignore. I lengthened my decompression profile and gingerly climbed out of the water, but my profound exhaustion told me I still had a problem. Too tired to do anything other than breathe oxygen and drink water, I collapsed on my sleeping mat and hoped everything would go away. My resolve was eroded. I had lost the ability to help myself. I was scared. Improvised in-water recompression at the dive site, an arduous hike out of the jungle, and three follow-up chamber runs resulted in a full but painful recovery. Looking back, I learned many things: The frequently reported symptom of denial extends far beyond embarrassment I m convinced that a bent, sick person knows they need help but simply can t ask for it. (It makes sense that if your body chemistry is that screwed up, it might affect your ability to speak up.) It is critical that somebody else on the team takes charge and makes decisions for a DCS victim. Second, oxygen is a powerful ally. Having plenty of rich gas on site saved me from grave injuries. Last, the long-term psychological effects of a DCS incident should be more widely discussed. Our community has correctly discarded terminology that divides decompression illness into deserved and undeserved hits DCS, like a football player s concussion or a runner s pulled hamstring, is a sports injury. When we share our experiences, all divers are better informed. And DAN insurance should be mandatory: I have watched DAN help countless colleagues through the incident and aftermath of diving injuries. Am I ever going to get bent again? I can t say, but I do everything I can to minimize the risk. Reprinted from Scuba Diving 3/31/2014.
