The Bajau are an indigenous people in parts of Indonesia renowned for their breath-holding ability when diving for food. They have been known to dive up to 70 metres using nothing more than a set of weights and a pair of wooden goggles.
Previously, scientists have speculated on whether dive capacity is related to spleen size, though no formal studies have been done on humans on a genetic level.
Our good colleague at Wetpixel, Adam Hanlon, recently reported that the extremely popular Eneloop rechargeable batteries are now not recommended for underwater strobe use. Panasonic, who owns Eneloop, specifically states on its website "Please do not use Eneloop Ni-MH batteries in underwater lights or other airtight appliances." Adam mentions it could be interesting if the strobe manufacturers have something to say, otherwise we’ll all keep using Eneloops as usual. It could indeed.
Is underwater photography difficult? Actually, no—at least, not to any significant degree when compared with any other discipline of photography. Each single stage of creating an underwater photograph, if seen in isolation from the rest, is not so tricky. It is the sum of all its parts, as well as mastering the whole, which can appear confusing at times.
For over a year, I had been looking forward to a very special expedition that was planned for May 2014. But as you know, life does not always go the way you plan. The expedition was postponed, and once again, I had to find an alternative, at relatively short notice.
Tritonia Scientific has taken over the operational management of the chamber after the Scottish Association for Marine Science (SAMS) indicated it could no longer support the facility.
This unit provides emergency treatment for divers who are suffering from decompression illness.
Mike Ange discuss methods of building a safer and more comfortable diver at the more advanced levels by preventing the diver from anticipating issues before they occur. While this may sound contradictory to the earlier articles in this series, in reality, it is taking those skills to the next level.
Although Visit Pensacola promotes the Oriskany dive site and Florida Panhandle Shipwreck Trail, it has not been made aware of the safety concerns rover the region's lack of hyperbaric chambers to treat decompression sickness Nicole Stacey, spokeswoman for Visit Pensacola, told Pensacola News Journal on Thursday.
She said Visit Pensacola was not involved in any effort to try to improve emergency treatment options for divers and would rely on the diving industry and those professionals in the area to remedy the situation.
The Diving Inspectorate has just issued this safety alert concerning cylinders manufactured from aluminium alloys HE30/AA6082 and AA6351 and used primarily for gases for underwater breathing apparatus.
This column is adapted from a chapter in my book, Scuba Physiological – Think you know all about Scuba Medicine? Think Again! The chapters in this book were originally written by scientists in the field of decompression research as part of a three-year project called PHYPODE (Physiology of Decompression). My (self-appointed) task was to rewrite their sometimes-complex research in a form accessible to all divers.
The waters off the coast of the US state of North Carolina are treacherous. Bad weather, rough seas, heavy current and inlets that are difficult to navigate are common. So why do underwater explorers consider this area to be a world-class dive destination? Because when you do get offshore, it is extraordinary.
The USS Lexington was scuttled about 800 kilometres (500 miles) miles off the eastern coast of Australia in May 1942 after sustaining serious damage from Japanese aircraft. A series of secondary explosions after the Japanese attack sealed the ship's fate and one of her own escorting destroyers was ordered to finish off the crippled carrier.
I first visited the Red Sea as part of a marine biological expedition with Dr Paul Cragg back in 1973. After having run safaris out of Israel and ending up living there for several years working on the legendary liveaboard dive boats Lady Jenny III and Lady Jenny V, my love for the Red Sea has never diminished. Now, some 45 years later, a return trip to the Red Sea was increasing my heartbeat in anticipation.
