  • Dr Craig Challen SC OAM
    Dr Craig Challen SC OAM Australian of the Year 2019, Thai Cave Rescue Diver, Aviator and Keynote Speaker Dr Craig Challen was named Australian of the Year 2019 in recognition of his work to rescue 12 young soccer players and their coach from a flooded Thai cave in Chiang Rai, Thailand in July 2018. Craig is in high demand as a keynote speaker. He presents alone or in partnership with fellow cave rescue diver Dr Richard Harris. An internationally recognised diver, a former vet, CEO and keen aviator, Craig is able to tailor his presentations to suit the audience and is available for question and answer sessions. More about Dr Craig Challen: Craig was about to go on a caving holiday in the Nullarbor Plains, when he was called to help the rescue mission based on his technical expertise. Although he initially thought the rescue would be too difficult to accomplish, he played a leading role in the successful mission. Working 10 to 12 hours a day in extremely dangerous conditions, he repeatedly risked his life as the children were swum, one by one, through the dark and narrow flooded caves. Craig was awarded the Star of Courage for his unwavering and selfless bravery. In 2019 he was recognised as Australian of the Year for Western Australia. One of Australia’s leading technical divers, Craig is a member of the Wet Mules, a diving group that takes on some of the world’s deepest caves. After commencing cave diving in the 1990s he was an early adopter of closed-circuit mixed gas rebreathers.

    XXXXXX DR CRAIG CHALLEN, a retired Perth veterinary surgeon and Australian technical diver and cave explorer, is THAI regarded as one of the best in the world. It was that reputation that led British diver Rick Stanton to call on CAVE Craig’s expertise to rescue the Thai football team from the Tham Luang RESCUE Cave, with his dive buddy and friend, anaesthetist Dr Richard (Harry) Harris. With around 20 years’ diving HERO TO experience, and a depth record (221 metres) to his credit, Craig and Harry were about to embark on another SPEAK AT cave diving adventure on the Nullarbor when the call came to help in the extraordinary rescue mission. BRISBANE The world held its collective breath while the life and death operation went into coordination mode as the CONFERENCE international team examined the best chance of rescue. Then came the rescue mode, and for a few days, Australian diver Dr Craig Challen, people everywhere hoped for a miracle that the boys would be saved. one of the heroes at the heart Not in living memory has there of the recent Thai cave rescue, been such a positive news experience as that which revealed the success will speak at next year’s Rotary of the mission, and the extraordinary Conference in Brisbane, Qld. courage and determination, guided by skill, that the team demonstrated throughout. Only when all the boys had been rescued did Craig and Harry leave the cave. Craig was a reluctant hero, but his attempts to avoid the media throng were overcome when the mission was successfully concluded, and all Australians shared an immense sense of pride in one of our own.

The whole world was watching. The chances were disturbingly slim. Anyone who knew anything about cave rescue had to recognise that. Thirteen young people were huddled in the chilly darkness, one monsoonal downpour from the end of their lives. And where was I? I was 7022 kilometres away, at my usual post in the operating theatre of Flinders Private Hospital in Adelaide, making sure a thyroid- ectomy patient didn’t wake up from her anaesthesia. I love being in theatre. But man! I’d never felt so far from the action in my life. Early that morning before work, a message had popped up on my phone. It was from the legendary British cave diver Rick Stanton, who had raced to the scene to help save the stranded members of the Wild Boars soccer team. ‘Could you sedate someone and dive them out?’ he wanted to know. 9781760890957_AgainstAllOdds_text_FINAL.indd 1 29/8/19 10:04 am 2 craig challen & richard harris Rick must be desperate, I thought. Or the pressure of the rescue has sent him round the bend. Otherwise, he’d never ask a question so absurd. Dive a sedated child underwater through the jagged maze of a dark, constricted cave? You’d kill the kid for sure.

  • Deployment and Recovery of a Full-Ocean Depth Mooring at Challenger Deep, Mariana Trench
    Deployment and recovery of a full-ocean depth mooring at Challenger Deep, Mariana Trench R.P. Dziak NOAA/Pacific Marine Environmental Laboratory, Newport, OR 97365 USA J.H. Haxel, H. Matsumoto Cooperative Institute for Marine Resources Studies Oregon State University Hatfield Marine Science Center, Newport, OR USA C. Meinig, N. Delich, J. Osse NOAA/Pacific Marine Environmental Laboratory, Seattle, WA 98115 USA M. Wetzler NOAA Ship Okeanos Explorer 439 West York Street, Norfolk, VA 23510 USA Abstract- We present the details of a unique deep-ocean instrument package and mooring that was deployed at Challenger Deep (10,984 m) in the Marianas Trench. The mooring is 45 m in length and consists of a hydrophone, RBR pressure and temperature loggers, nine Vitrovex glass spheres and a mast with a satellite beacon for recovery. The mooring was deployed in January and recovered in March 2015 using the USCG Cutter Sequoia. The pressure logger recorded a maximum pressure of 10,956.8 decibars, for a depth of 10,646.1 m. To our knowledge, this is only the fourth in situ measurement of depth ever made at Challenger Deep. The hydrophone recorded for ~1 hour and stopped shortly after descending to a depth of 1,785 m (temperature of 2.4C). The record at this depth is dominated by the sound of the Sequoia’s engines and propellers. I. INTRODUCTION From January to March 2015, a specially designed deep-ocean hydrophone and pressure sensor mooring was deployed in the deepest area of the world’s oceans; Challenger Deep. The goal of the project was to make a direct pressure-based measurement of ocean depth at Challenger Deep, and to record the ambient sound levels within this unique, ultra-deep (> 10 km) ocean environment.

  • Deepsea Challenger Sub Damaged in Truck Fire 23 July 2015
    Deepsea Challenger sub damaged in truck fire 23 July 2015 The sub's owner, the Woods Hole Oceanographic Institution in Falmouth, Massachusetts, said in a statement that the fire caused some damage to the submarine. The extent of the damage and the fire's cause are under investigation. The sub was to be shipped to Baltimore and then Australia on a temporary loan. © 2015 The Associated Press. All rights reserved. An investigator who declined to be identified looks over the damage to the Deepsea Challenger deep-diving submersible resting on its transport trailer in North Stonington, Conn. Thursday, July 23, 2015. The vessel was damaged by fire while being transported along I95 from Woods Hole to Baltimore. Filmmaker and ocean explorer James Cameron piloted the submersible in 2012 to a depth of nearly 35,800 feet (10,900 metres) in the deepest spot on the planet—the Mariana Trench near Guam. (Sean D. Elliot/The Day via AP) The submarine that visited the deepest spot in the world's oceans has been scorched when a truck transporting the vessel caught fire on a Connecticut highway. State Police responded to the Thursday fire on a truck transporting the Deepsea Challenger on Interstate 95 in North Stonington.
