The University of Florida Diving Science and Safety Program AAUS STANDARDS for SCIENTIFIC DIVING
The University of Florida Diving Science and Safety Program AAUS STANDARDS FOR SCIENTIFIC DIVING 2019 1 FOREWORD Since 1951 the scientific diving community has endeavored to promote safe, effective diving through self-imposed diver training and education programs. Over the years, manuals for diving safety have been circulated between organizations, revised and modified for local implementation, and have resulted in an enviable safety record. This document represents the minimal safety standards for scientific diving at the present day. As diving science progresses so must this standard, and it is the responsibility of every member of the Academy to see that it always reflects state of the art, safe diving practice. American Academy of Underwater Sciences ACKNOWLEDGEMENTS The Academy thanks the numerous dedicated individual and organizational members for their contributions and editorial comments in the production of these standards.

No Limits Freediving
1 No Limits Freediving "The challenges to the respiratory function of the breath-hold diver' are formidable. One has to marvel at the ability of the human body to cope with stresses that far exceed what normal terrestrial life requires." Claes Lundgren, Director, Center for Research and Education in Special Environments A woman in a deeply relaxed state floats in the water next to a diving buoy. She is clad in a figure-hugging wetsuit, a dive computer strapped to her right wrist, and another to her calf. She wears strange form-hugging silicone goggles that distort her eyes, giving her a strange bug-eyed appearance. A couple of meters away, five support divers tread water near a diving platform, watching her perform an elaborate breathing ritual while she hangs onto a metal tube fitted with two crossbars. A few meters below the buoy, we see that the metal tube is in fact a weighted sled attached to a cable descending into the dark-blue water. Her eyes are still closed as she begins performing a series of final inhalations, breathing faster and faster. Photographers on the media boats snap pictures as she performs her final few deep and long hyperventilations, eliminating carbon dioxide from her body. Then, a thumbs-up to her surface crew, a pinch of the nose clip, one final lungful of air, and the woman closes her eyes, wraps her knees around the bottom bar of the sled, releases a brake device, and disappears gracefully beneath the waves. The harsh sounds of the wind and waves suddenly cease and are replaced by the effervescent bubbling of air being released from the regulators of scuba-divers. -
Monofins for Freediving
Monofins for Freediving We have been intermittently following the debate concerning the use of the monofin in freediving and would like to share some of our findings. Two years ago we put together the first experimental monofin/freedive clinic where we assembled some unique elements. We put together the leading trainers in monofin swimming, namely the Russian coaches from Tomsk university, who train both the Russian national team and their chief rivals, the Chinese, the leading specialist monofin manufacturer belonging to the same school and a group of freedivers which represented the best cross-section, from the very top of freediving competition to the very novice. This same group also represented advanced freedivers who already had experience with the monofin, advanced freedivers who had never used a monofin and a novice freediver with no experience of the monofin. Although the number of freedivers involved was small we feel that with a larger group the conclusions would have been much the same. The objectives were to find (i) What style and why? (ii) What rhythm and amplitude of movement? (iii) What kind of monofin and what stiffness of blade and if this was individual what the relevant criteria for monofin choice should be? (iv) What compromises and adaptations had to be made to suit the specific needs of the freediver? (v) What was the best training method for the monofin freediver. What style and why? We had heard a lot of talk concerning adaptations of the ‘classic ’style that freedivers should adopt. I know from personal acquaintance that some of the people recommending various adaptations were not capable of demonstrating a good classic style hence their recommendations were from lack of ability in the monofin and hence lack of choice through limited ability. -

DPD2 • RNAV2 • AP2 • OM2 • AC2 • POWER POD • CP2 CATALOG 22 POWER POD NEW! RNAV2 SIMULATOR Manned & Autonomous Vehicles with Navigation, Control & Communications for EOD and Maritime SOF stiddmil.com MADE IN U.S.A. Manned or Autonomous... The “All-In-One” Vehicle Moving easily between manned and autonomous roles, STIDD’s new generation of propulsion vehicles provide operators innovative options for an increasingly complex underwater environment. Over the past 20 years, STIDD built its Submersible line and flagship product, the Diver Propulsion Device (DPD), around the basic idea that divers would prefer riding a vehicle instead of swimming. Today, STIDD focuses on another simple, but transformative goal: design, develop, and integrate the most advanced Precision Navigation, Control, Communications, and Automation Technology available into the DPD to make that ride easier, more effective, and when desired . RIDERLESS! DPD2 - Manned Mode 1 DPD2 - OM2 Mode Precision Navigation, Control, Communications & Automation System for the DPD POWERED BY RNAV2 GREENSEA Building on the legacy of its Diver Propulsion Device (DPD), the most widely used combat vehicle of its kind, STIDD designed and developed a system of DPD Navigation, Control, Communications, and Automation features which enable a seamless transition between Manned and fully Autonomous modes. RNAV2 was developed by STIDD partnering with Greensea as the backbone of this capability. RNAV2 is powered by Greensea’s patent-pending OPENSEA™ operating platform, which not only enables RNAV2’s open architecture, but also seamlessly integrates STIDD’s OM2/AP2 Diver Assist /S2 Sonar/ AC2 Communications products into an intuitive, easy to use, autonomous system. When fully configured with the Precision Navigation, Control & Automation System including RNAV2/ OM2/AP2/S2/AC2, any DPD easily transitions between Manned, DPD with RNAV2 Installed Semi-Autonomous, and Full-Autonomous modes. -
