Practice What You Preach

Q1 2021

All diving has risks. To mitigate them, we must always pay attention to the details. The predive safety check is of utmost importance to help avoid a dive accident. The key elements are for each buddy to check the other’s BCD, weights, releases and air, and then give a final check and decisive OK. I could have avoided the entire incident had I adhered to my predive safety check and not gotten distracted, and I should have performed the safety check again before getting in the water.

Diving After a Stroke

Q1 2021

Carefully weigh your return to diving, and assess the risk versus reward. No studies are available that address if the areas of your brain damaged by your stroke will be more susceptible to decompression illness. If you decide to dive, seek a detailed ongoing assessment and approval from your physician. This process should include a neurological evaluation that includes the strength and weakness of major muscle groups and the degree of cerebral injury as well as an assessment and comparison of the left side and right side of your body.

Exercising in water can be a great way to mix up your routine. The water supports your body
and ensures low impact despite intense exercise. The effects of gravity are less profound in the water, so you can have an increased range of motion and move in different directions than on land without falling. Water also offers resistance that activates your core muscles for stability, which is beneficial when maneuvering during diving. An added benefit for divers is practicing comfort and control in the water.

Heart Trouble in Tahiti

Jack Estill

Q1 2021

While on a trip to Tahiti, a 71-year-old experienced diver and competitive rower coughed up foamy blood after making three recreational dives on nitrox. He called DAN for advice and later saw a cardiologist, who diagnosed him with exercise-induced mitral valve prolapse. This diver recommends that divers continue to educate themselves, maintain their DAN membership and insurance coverage, go slowly if they haven’t dived in a while, be prepared and practice for emergencies.

Current Dives

Diving in currents can be exhilarating, but it can also be hazardous if you do not have the proper training or are unprepared. To get the most enjoyment, perform proper predive research and dive planning. Make sure you prepare physically and mentally and have the proper gear, training and experience. Divers often say that current dives are some of their most memorable and exhilarating dives.

Photographer Cristina Mittermeier’s social media posts have insightful captions that reveal her deep commitment to ocean ecology issues. Telling stories that inspire, engage and ultimately motivate action, she wants to show what’s beautiful and special but also what may be in dire peril. Perhaps most significantly, she wants to show her audience an opportunity to act positively and to possibly attain a solution, using her photography to shine a light and make a difference.

Models and Marine Life

Stephen Frink

Q1 2021

Underwater photographers usually evolve a specialty, but the first fork in their road typically involves defining an interest in either photographing natural history — marine life in particular — or concentrating on editorial and commercial work that inevitably involves photographing people underwater. Photos of charismatic marine life help tell the story of a dive destination or might be used for photo décor or stock photography. Compositions that illustrate people interacting with marine life bridge both disciplines and combine each approach’s rewards and challenges.

Sentinels for the Seas

The U.S. currently has 14 national marine sanctuaries and two marine national monuments, and each has its own unique story. In preserving these irreplaceable resources, the sanctuaries protect who we are at our base — our soul as a nation. They reaffirm us and connect us to our incredible heritage.
