World renowned diving researcher Dick Vann dies

He had been battling multiple myeloma since 2010.

The family of Dr Richard Vann wishes to thank everyone for their tremendous outpouring of love for such a wonderful man.

Dick was a beloved husband, father, colleague and friend and we will all miss him dearly

Dick Vann's family have confirmed that in accordance with his wishes, his ashes will be scattered in Maine, where his parents and grandparents are interred.

Management of decompression stress

World-renowned diving medicine expert Dr Neal Pollock gave everyone a lot to think about with his talk on the thoughtful management of decompression stress.

Neal looked at the many factors that can alter decompression stress and the practical strategies all divers can use to optimise decompression safety.

“It is increasingly common for divers to rely on dive computers for their decompression safety. Dive computers do not yet measure or integrate a multitude of factors that can alter decompression stress.”- Dr Neal Pollock.

Dr. Richard D. Vann to be awarded prestigious NOGI

This coveted award is widely recognised as the oldest and most prestigious in the diving industry. The NOGI has been awarded on an annual basis since 1960 to a select group of divers and undersea visionaries who rank at the top of their fields in arts, science, sports / education, environment, and distinguished service. In 1993 the AUAS was created to administer the NOGI award.

The Clock — Extend dive time with physical fitness

Tick tock tick tock. Have you ever heard someone say, “There goes 15 minutes of my life I will never get back?” While there are many different philosophies and applications of time, most divers don’t want to waste it. Instead, divers carefully invest some of their precious time, energy and money planning and preparing for their ideal SCUBA experience.

Why is Scientific Diving Safer?

Scientific diving appears to be one of the safer forms of diving, a recent study of incidences of decompression illness over ten years has found. This safety seems to be facilitated by a combination of relatively high levels of training and oversight, the predominance of shallow, no-decompression diving and, possibly, low peer or institutional pressure to complete dives under less than optimal circumstances.

Using ultrasound to improve diver safety

If the bubbles are on the right side of the heart, they will enter the lungs which can handle them. If the bubbles are on the left side of the heart, they would then go into the body and get lodged somewhere, causing the bends.

Accord to Dr Pollock, the future of ultrasonic monitoring can be found in dual-frequency ultrasound. In this technique, two transducers are used. One excites the bubbles and the other allows the user to identify when a bubble starts to vibrate.
