The vast majority of AP rebreather divers will have been informed of this update by email. However it has come to APD's attention that some of their registered Inspiration users have not received the mailing. This is either because the email address APD has on record is out-of-date or the mailing has been rejected by the individual's spam filter.
AP Diving has therefore made the following request.
When air-breathing mammals dive, their lungs compress. The ultra-deep-diving feats of some marine mammals go beyond our current understanding of respiratory physiology and lung mechanics. But historically, researchers assumed the chest structure of marine mammals meant their lungs compressed automatically at great depths, an adaptation that prevented them from taking up excess nitrogen and getting the bends.
On 10 May 2018 David Jones will be talking on "Marine Plastic Pollution: How did we get here and what can we do about it?"
Plastic pollution is undoubtedly one of the biggest environmental issues we face at the moment. Plastic has only been in our lives for around seventy years, so how did we get to where we are, what went wrong? More importantly, what can we do about it?" David Jones.
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.
