  • Our World-Underwater Scholarship Society ®
    our world-underwater scholarship society ® 47th Annual Awards Program – June 3 - 5, 2021 Welcome to the 47th anniversary celebration of the Our World-Underwater Scholarship Society®. It has always been a great pleasure for me as president of the Society to bring the “family” together each year in New York City, so of course it is with great disappointment that for the second year we are unable to do so. A year ago, as the pandemic was beginning to spread throughout the world, the board of directors made the difficult decision to put all scholarship and internship activities on hold. 2020 was the first time in the Society’s history that we did not put Scholars or Interns in the field. But there is good news – the Society has new energy and is working with our hosts and sponsors to safely get our incoming 2021 Scholars and Interns started on their journeys. We bring three new Rolex Scholars and five new interns into our family for a total of 103 Rolex Scholars and 107 interns since the inception of the Society, and all of this has been accomplished by our all-volunteer organization. Forty-seven years of volunteers have been selfless in their efforts serving as directors, officers, committee members, coordinators, and technical advisors all motivated to support the Society’s mission “to promote educational activities associated with the underwater world.” None of this would have been possible without the incredible support by the Society’s many organizational partners and corporate sponsors throughout the years. The one constant in the Society’s evolution has been Rolex which continues to support the Society as part of its Perpetual Planet Initiative.

  • IMPORTANT NOTICE Please Read This Document Before Using the Product As New Features Will Require You to Modify Your Operational Techniques
    [Type text] AP Restricted HP Hoses & Progressive-Opening Oxygen Cylinder Valves IMPORTANT NOTICE Please read this document before using the product as new features will require you to modify your operational techniques. Prevention of Oxygen Fires Closed Circuit Rebreathers, over the past 22 years, have brought about the widespread use of pure oxygen by divers. All Nitrox trained divers know that handling pure oxygen requires special care, regarding operation & use, cleanliness, lubrication and replacement regimes but over time it has become clear that protocols for handling oxygen have to be reviewed and improved. Oxygen fires are thankfully quite rare, but when they do occur, they can result in serious damage to people and possessions and every effort has to be made to avoid them. From our research into oxygen fires, six important facts Jump out: 1) Oxygen fires always occur when the valve is opened. 2) The diver’s perception of what is slow opening is WRONG. 3) Rented or borrowed cylinders represent a greater risk than the diver using his original cylinders. 4) 50% of oxygen fires start in the HP hose. 5) 50% of fires start in the 1st stage. 6) The oxygen HP hose always burns in an O2 fire and is falsely seen as the culprit. Type Testing: For type approval testing of oxygen compatibility of AP components and valves; testing is done by instantly pressurising products with hot oxygen to between 290 and 350 bar. (Instant pressurisation = <20mS; hot oxygen = 70oC ). Fast pressurisation is something that divers get away with, while there is no contamination present.

Award-winning underwater cin- ematographer and documen- tary producer Nathalie Lasselin reflects upon her dive expedi- tions in the Arctic and her epic project to raise awareness about the state of fresh water in the St Lawrence River, closer to home in Montreal. It was the end of April, and it was sup- posed to be the end of winter. But once again, I had to refrain from putting my thick winter coat on the very top shelf of my wardrobe. I was already looking for the first barbecue party with friends, but the north was calling me—the Great Canadian North—and how could I say no to going back to the floe edge? So, I packed my winter coat, my diving and filming gear, and headed to a small vil- lage in the remote north the endless white sheet of ice, punctuat- amazing animals like polar bears, walrus anchored to the bottom of the ocean called Pond Inlet.

  • Ambient Pressure Diving Ltd
    Ambient Pressure Diving Ltd Equipment Inspection following a diving incident. A step by step guide: 1) Photography: It is absolutely essential to photograph everything. Sometime later when you are working through scenarios, you will need to know what was connected to what, which side each cylinder was, how close to his body was it mounted, did he have dive reel etc – the possibilities of future questions are endless and the photos taken at this stage could prove invaluable. I would strongly advise that the photographer be a separate person to the equipment examiner and ensure the photographer is briefed on getting a shot of everything both prior and during dis-assembly. 2) Record Keeping: Again, it is absolutely essential to record everything you do and find. E.g. If you are inspecting the diluent side and find no fault then write “No fault found” – you are going to need this data later. The equipment inspection is a time for data collection – leave the analysis of the cause of the incident until afterwards, when you have all the data in and you have time to cross- reference with autopsy findings and statements. 3) Autopsy: All too often a verdict of “death by drowning” is recorded. A proper autopsy can reveal much: Contact Dr M. Calder – [email protected] Telephone: 01223 277220 – he’s a pathologist specialising in deaths in water. 3) Recovery: On the bottom: The divers need to be briefed on what to look for: Does the diver have his mouthpiece in? Mask On? Is he heavy on the bottom or semi-floating? Is there a beeping noise? If so –where is it coming from? Are there any bubbles – if so where from? Ensure they do not touch the cylinder valves.

  • The Jump Jacket MK4 Instruction Manual
    The Jump Jacket MK4 Instruction Manual Version June 2008 Produced by Gary Jones and A.P.Valves JUMP JACKET MK4 THE JUMP JACKET Mk4 INTRODUCTION The Jump Jacket Mk.4 has been designed to be used in the commercial diving industry, specifically for surface air and mixed gas diving, to allow the diver total control of his buoyancy. The emphasis has been heavily placed on safety and efficiency, allowing the diver greater flexibility under water without drawing on emergency energy levels. Expanding on the safety features of the MK.3 Jacket, the general concept is to give the diver more control of his buoyancy and expand his options in an emergency situation. GENERAL DESCRIPTION The Mk.4 Jacket has been designed to be used in conjunction with a KMB.17 b/c diving helmet. As well as the normal buoyancy control and performance expected of the previous jackets, the Mk.4 offers direct feed supply to the jacket from the divers main gas supply, also an emergency supply from the diver’s bailout. Another safety feature is the ability to buddy breathe two divers from one umbilical supply in an emergency situation. With the incorporation of a helmet safety harness, the Mk.4 Jump Jacket is the only stand alone commercial diver’s buoyancy control unit that incorporates a full recovery diver’s harness, helmet harness and bailout backpack. The Mk.4 Jacket has been designed to be used with an umbilical supply, but can be used independently if required. The pressure relief /dump valves allow the Jacket to be passed in and out of diving systems without rupture or damage to the inner bladder and gives the diver total control of his buoyancy.
