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. -
South Australia's National Parks Guide
SOUTH AUSTRALIA’S NATIONAL PARKS GUIDE Explore some of South Australia’s most inspirational places INTRODUCTION Generations of South Australians and visitors to our State cherish memories of our national parks. From camping with family and friends in the iconic Flinders Ranges, picnicking at popular Adelaide parks such as Belair National Park or fishing and swimming along our long and winding coast, there are countless opportunities to connect with nature and discover landscapes of both natural and cultural significance. South Australia’s parks make an important contribution to the economic development of the State through nature- based tourism, recreation and biodiversity. They also contribute to the healthy lifestyles we as a community enjoy and they are cornerstones of our efforts to conserve South Australia’s native plants and animals. In recognition of the importance of our parks, the Department of Environment, Water and Natural Resources is enhancing experiences for visitors, such as improving park infrastructure and providing opportunities for volunteers to contribute to conservation efforts. It is important that we all continue to celebrate South Australia’s parks and recognise the contribution that people make to conservation. Helping achieve that vision is the fun part – all you need to do is visit a park and take advantage of all it has to offer.

The Making of a Connection – The Potential of a Mammoth Cave System-Whigpistle Cave Connection 1 1 2 Patricia Kambesis , Joel Despain , Chris Groves 1 Cave Research Foundation 2 Hoff man Environmental Research Institute, Western Kentucky University Abstract The current length of the Flint Ridge-Mammoth Cave System (to be called Mammoth Cave System for the rest of this paper) has been attained by a series of connections instigated by cave explorers/mappers of the Cave Research Foundation (CRF) and Central Kentucky Karst Coalition (CKKC). Between 1961 and 2011, connections have expanded the surveyed extent of the cave system to its current “offi cial” length of 390 miles (650 km). -
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. -

The Environmental, Social and Human Health Importance of the Aquifers and Wetlands of the Lower South East of South Australia An
The environmental, social and human health importance of the aquifers and wetlands of the Lower South East of South Australia and SW Victoria and the increasing threats to their existence. My submission to the Senate Select Committee on Unconventional Gas Mining March 2016 I am Marcia Lorenz B.A. Grad. Dip. Ed. Admin., a retired school teacher. I only discovered the attractions of the South East when I came to Beachport 12 years ago. I am a volunteer at the Millicent High School where I support the Aboriginal children in their work with their culture and the environment. I am also a volunteer with other environmental groups in the region. My submission concerns the likely detrimental effect of unconventional gas extraction (“fracking”) on the aquifers and wetlands of the South East of South Australia and therefore on the myriad of species, both flora and fauna that constitute wetland habitats. 1 HISTORY Historically, post white settlement, wetlands were viewed as wastelands with no thought being given to the natural environment and the diversity of species they contained. Economics was the driving force. It would be wonderful if we could say that times have changed and politically there is the realisation that in order for humans to exist, the natural environment must be taken into consideration. After all we now have knowledge that wasn’t available to the ordinary person in the early days of settlement. Post European settlement change in land use has significantly altered the landscape of the South East resulting in the loss of many areas of wetland habitat with <6% of the original wetland extent now remaining.1 An estimated 2,515 km. -

Survey Guidelines for Australia's Threatened Fish
Survey guidelines for Australia’s threatened fish Guidelines for detecting fish listed as threatened under the Environment Protection and Biodiversity Conservation Act 1999 Authorship and acknowledgments This report updates and expands on a report prepared in May 2004 by Australian Museum ichthyologist John Pogonoski and approved by AMBS Senior Project Manager Jayne Tipping. The current (2011) report includes updates to the 2004 report and additional information regarding recently listed species, current knowledge of all the listed species and current survey techniques. This additional information was prepared by Australian Museum ichthyologists Dr Doug Hoese and Sally Reader. Technical assistance was provided by AMBS ecologists Mark Semeniuk and Lisa McCaffrey. AMBS Senior Project Manager Glenn Muir co- ordinated the project team and reviewed the final report. These guidelines could not have been produced without the assistance of a number of experts.
