Snap, Crackle, Pop: Healthy reef sounds can diagnose health and support restoration (***Remote Speaker***)

***Remote Speaker***

Aran Mooney is a marine biologist focusing on the sensory biology and bioacoustics of marine organisms. He received his B.S. from the University of New Hampshire (2000; Biology with Spanish minor) and a M.S. (2003) and Ph.D. (2008) from the University of Hawaii (Zoology – Marine Biology emphasis). At UH Mooney conducted research on acoustically reducing dolphin and porpoise bycatch and the effects of noise on marine mammals. After his degree, Dr. Mooney worked at the Marine Biological Laboratory and then the Woods Hole Oceanographic Institution (WHOI) as a Postdoctoral Scholar.  He is currently an Associate Scientist at WHOI.  Dr. Mooney’s research focuses on sensory biology and particularly how marine animals detect, use and are affected by sound.  This involves measuring sound sensitivity in a diversity of marine animals, monitoring biological activity and reef health via underwater soundscapes, defining hearing capabilities in organisms not previously known to use sound, such as squid and cuttlefish and developing new sensors to measure sound production, biodiversity and animal behaviors. To achieve these tasks, he works with engineers to develop new sensors and biologging tags.

The Woods Hole Oceanographic Institution (WHOI) is a leading non-profit research and higher education facility dedicated to ocean science, technology, education, and communication. Founded in 1930, it conducts research across various marine science disciplines and is a major center for oceanographic studies. WHOI's mission is to advance understanding of the ocean and its interaction with the Earth system, and to apply this knowledge to benefit society.  WHOI has been a pioneer of bioacoustics research for nearly 100 years.

        REMINDER, our meeting location has changed to the Pompano Beach Elks Lodge. The new room is large and much better acoustics than our previous location. The Lodge opens at 5:00 and they have assured us they will have food available, so please come and learn about our new location. The meeting will start at 7:00 since the Lodge closes at 9:00 and we need to be out of the building. We are required to prepare and clean up the space(part of the savings) so any help is appreciated. There is one aspect that we need to be aware of, because this is a private club only members(Elks) can purchase alcohol. Everybody else will need to pay the member(elks) for any drinks they order on that member(Elks)’s tab.

        As always, we would love members that are interested in helping or getting to know the club better to join the Board of Directors. We would enjoy some new blood and the perspective of new members.

        Our schedule is filling up with new Local Dives and Social Events, please come out and join your fellow members. We all joined the club for these activities and the friends we have made through the years.

        Happy diving,

        Chris Hardham
        President

        Hospitality Hut


           

        Greetings From The Hospitality Hut,

        As you know by now, we have a new meeting place.  On May 1st, the USA Dive Club will begin to hold its' monthly meetings at the Elks Lodge #1898 located in Pompano Beach.  Looking forward to seeing you there.

        At the April general meeting, I was happy to introduce the aunt of our speaker. Kathy Sanchez accompanied Aaron who  presented a very interesting program.  Kathy is not a diver.  She lives in White Plains, NY. Kathy was so impressed with our group, she has asked to be added to our email list where she can keep up with our activities.

        I encourage you to visit our home page www.usadiveclub.org.  Please click on the calendar and keep up to date on all the diving and non-diving scheduled activities. You may also take a look at the photo gallery and take a peek at past events.

        I wish you all Happy Diving.

        Chest compressions — The first-line response



        Cardiopulmonary resuscitation (CPR) is a lifesaving skill, helpful in many situations including:

        • Cardiac arrest

        • Drowning

        • Trauma

        • Electrical shock

        The American Heart Association recommends that everyone — untrained bystanders and medical personnel alike — begin CPR with chest compression. 1

        CPR uses chest compression to imitate how the heart transports blood to the whole body. These compressions help keep oxygenated blood flowing to the brain and other vital organs until proper medical treatment can be provided. 2

        During cardiac arrest, stoppage of oxygenated blood supply can damage the brain in only a few minutes. It can prove to be fatal within eight to ten minutes. 1

        Why is compression necessary?

        The opportunity for a successful resuscitation can be extended by keeping the blood flow active, even partially, until trained medical help arrives on site. 3

        CPR saves a life

        At present, about ninety percent of the people who suffer cardiac arrest outside the hospital expire. However, CPR improves the chances of saving a life if it is performed at the beginning of the cardiac arrest. The prospect of saving a person’s life can be double or triple with CPR. 2

        Recognition of cardiac arrest

        The person is healthy one moment, and you unexpectedly see or hear them fall down. You check for consciousness by “shaking and shouting” (Are you alright?) and rub the sternum with your knuckles. This helps to decide whether a person has had some other injury or they are suffering cardiac arrest. If the person doesn’t respond, you should assume that the person has experienced cardiac arrest.

        Call for help immediately.

        It is most important to call 911. Chest compression circulates some oxygen until help arrives. Tell someone or call yourself for emergency responders. Start chest compressions. Do not delay chest compressions if the pulse cannot be felt within 10 seconds. Immediate chest compression increases the chances of survival. 4

        Chest compressions

        A person present on the site, whether trained or not, should start chest compressions to the victim suffering cardiac arrest. Chest compressions are now the first-line response rather than opening the airway and delivering rescue breathing. High-quality chest compressions are necessary. Follow the mantra: “push fast and push hard on the center of the chest (i.e., sternum).”

        • Chest compressions must be at least 2 inches deep with each down-stroke.

        • The rate of compressions must be 100 to 120 per minute.

        • While performing chest compressions, the duration and frequency of interruptions must be minimized.

        Chest compressions with ventilation can be provided by those trained in the technique and professional medical staff.

        Complications

        The object of chest compression is to supply blood to the brain, heart, and other vital organs of the body until accurate medical treatment can be provided. If chest compression is not started as quickly as possible, the person experiencing cardiac arrest is likely to die. Complications may include fractures of the ribs, broken teeth, infections, and punctures of the lung. 5 The risk of injury should not stop anyone from performing CPR. If CPR is performed on someone who doesn’t need it, though it can be uncomfortable for that person, only about 2% suffer any type of injury as a result.

        Conclusion

        It is very uncommon for only chest compressions to recover the heart. However, by continuing constant chest compressions you can dramatically improve the odds of survival by maintaining the victim’s heart in a condition that increases the likelihood that shocks from a defibrillator, administered through bystanders using an automated external defibrillator (AED) or administered by paramedics will result in survival. 4

        Chest compressions are the first line response in CPR. If you are hesitant to do mouth-to-mouth, chest compressions alone may still be life-saving.5 It’s far better to do something than to do nothing if you are afraid and doubtful of your knowledge and abilities. Remember, the difference between you doing something and doing nothing could be someone’s life. 1 For more information in this regard check out our ACLS BLS recertification online and take CPR online classes.

        Membership



        We’re thrilled to welcome back Rob Myers to the USA Dive Club.  Rob, a former member, has been a passionate diver since the early 1970s and holds certifications as an Advanced Open Water/NITROX Diver.  Rob is married to USA Hall of Fame member Patrice Marker.  He is often seen at our social events and lending his voice as a guest speaker during our general meetings.

        Rob is not just an experienced diver; he’s also certified by DAN in CPR, Oxygen First Aid for Scuba Diving Injuries, and First Aid for Hazardous Marine Life Injuries.  Rob is a marine scientist specializing in coral reef fishes.  He started photographing marine life in 1970 and has written several identification guides, including Micronesian Reef Fishes, Coral Reef Fishes – Indo-Pacific and Caribbean, Coral Reef Guide - Red Sea, and Dangerous Marine Animals.

        Rob had a hand in naming two gastropod mollusks after his wife, Patrice - a deepwater cone snail from Brazil (Lamniconus patriceae) and a local subspecies of moon snail (Neverita delessertiana patriceae) known only from Lake Worth lagoon.  More recently, he’s been trying to prioritize the next edition of Micronesian Reef Fishes.

        One of his fondest memories is from 1980 when he discovered a new species of butterflyfish…a true highlight of his diving adventures.  His dream dive spot?  Anywhere teeming with beautiful fish.  When he’s not under the waves, Rob loves educating others about natural history, biogeography, and the beautiful small creatures that inhabit our planet. 

        Craig and Judith Pugatch found out about the USA Dive Club from President Chris Hardham. They’re a friendly family living in Lighthouse Point, and they have a lovely 14-year-old daughter named Alana.  Alana is already on her way to becoming a diver with her Junior Open Water certification, and she can’t wait to join the Club officially when she turns 18.  Until then, she’s all set to be with Mom and Dad on USA’s fun dives and events as their special guest. 

        Craig is an enthusiastic PADI Open Water Instructor with over 500 dives under his belt, while Judith shines with her certifications from PADI, NAUI, and IDA—she’s a Master Diver with 250 dives. 

        One of their most unforgettable diving experiences together was with the mesmerizing Kona mantas, and they look forward to more adventures with us.

        Let's all give Rob, Craig, Judith, and their special guest Alana a warm "Welcome to the USA Dive Club."  We're so happy to have you with us.

        Join us at our in-person meetings to connect and socialize with fellow dive enthusiasts and be entertained and educated by our guest speakers.  Feel free to bring along a friend or two.  It's a great way to make new memories together.

        As always, we invite you to browse through our extensive Photo Gallery to take a look at our social and diving activities.

        Happy diving, everyone.  Let’s keep the good vibes going!
