Six divers yesterday emerged safe and well from a living chamber that had taken them more than 300 meters under the sea, marking the success of China’s first 300-meter saturation dive experiment.
After remaining in the chamber for 380 hours, Hu Jian, Guan Meng, Dong Meng, Tan Hui, Luo Xiaoming and Li Hongjian came out around 9am, all in good health.
“This puts a successful conclusion to China’s first 300-meter saturation dive,” said Shen Hao, head of the Shanghai Salvage Company under the Ministry of Transport, which was responsible for the project.
On January 9, the six divers went into the living chamber, which was pressurized to the level 300 meters undersea.
The chamber took them 300 meters deep on January 12 and then witnessed them diving to as deep as 313.5 meters, said Shen.
Saturation diving technology enables human beings to withstand high water pressure by saturating human tissue with inert gas. This will allow divers to stay underwater for a longer time and at a deeper sea level than with conventional techniques.
It is used in deep-sea exploration, in rescue operations at sea and in engineering construction at the bottom of the sea.
China is researching technology that would work at 500 meters down, Shen said.
The Big Shark Pledge: Shark Trust’s new campaign kicks off with a call for support
With the ink still drying on last week’s landmark listing of nearly 100 species of sharks on Appendix II of CITES, the Shark Trust insists that this is not the time for shark conservation to take a break. The UK-based NGO this week launches its biggest-ever concerted campaign to tackle the overfishing of oceanic sharks. They are calling on people across the world to join the call for stricter controls on high seas fisheries.
The Big Shark Pledge is at the heart of an ambitious set of campaign actions. Working to secure science-based catch limits on all sharks and rays affected by the international high seas fishing fleet. The pledge will build the largest campaigning community in shark and ray conservation history to support a raft of policy actions over the vital years ahead.
Many of our best known and much-loved sharks make their home on the high seas. In our shared ocean, these oceanic sharks and rays face a very real threat from a huge international fleet of industrial-scale fishing vessels. Research published in early 2021 confirmed that over three-quarters of oceanic sharks and rays are now at risk of extinction due to the destructive impact of overfishing. They have declined by 71% over the last 50 years.
The Shark Trust is celebrating its 25th Anniversary this year and has a long history of securing positive changes for sharks, skates and rays. The Big Shark Pledge will build on the success of their NoLimits? campaign which underpinned landmark catch limits on Blue Sharks and Shortfin Mako in the North Atlantic.
“While the listing of so many species on the CITES trade agreement is certainly a positive step, there remains a huge challenge in ensuring that sustainable practices are embedded in international fisheries.” says Shark Trust Director of conservation, Ali Hood. “Sharks on the high seas face extraordinary pressure from excessive fishing practices. This has to be addressed through international agreements such as those secured for Blues and makos.”
There is hope and a feeling of momentum in the shark conservation community. Just last week, in addition to the new CITES listings, the Shark Trust, working with partners in the Shark League, secured the first-ever international quota for South Atlantic Mako at ICCAT meeting in Portugal. The new campaign from the Shark Trust aims to push forwards from here, engaging a wave of support through the Big Shark Pledge to bolster policy action.
This will be a long-term international and collaborative effort. Forging a pathway to rebuild populations of high-seas sharks and rays. By putting science at the heart of shark conservation and fisheries management. And making the vital changes needed to set populations on the road to recovery.
Shark Trust CEO Paul Cox says of the Big Shark Pledge “It’s designed to give everyone who cares about the future of sharks the chance to add their voice to effective and proven conservation action. By adding their name to the Pledge, supporters will be given opportunities to apply pressure at key moments to influence change.”
Jeff chats to… Craig Waller, Underwater Lighting Technician on Black Panther: Wakanda Forever (Watch Video)
In this exclusive Zoom interview, Jeff Goodman, Scubaverse Editor-at-Large, chats to Craig Waller, Underwater Lighting Technician on Black Panther: Wakanda Forever. Craig is a Key Grip and Lighting Director with 10,000s of hours of Set Experience.
In Craig’s own words:
I started my career when I was in my first year of college. I always had that creative side of the brain that needed to be followed as a career. I thought that would be in designing engineering pieces but wasn’t happy about the idea of an office cubicle and drafting table.
I accidentally found my way onto a big commercial job for a week and decided “THIS IS WHAT I WANT TO DO”. I made it my career after that. This is a quick list of recent and big projects in my 35 yrs of TV / Film / Photography.
- “Black Panther 2” – UW Lighting Technician / 2nd Unit Underwater Team
- “Stranger Things” Season 4 – UW Lighting Technician / 2nd Unit Underwater Team
- “Suicide Squad 2” – UW Gaffer / 2nd Unit Underwater Team
- NASCAR / FOX Sports 1 – Network TV Lighting Director – 7 years / 700 races of Live BIG track TV shows
- 10,000s of commercials / music videos / tv shows
I started diving when I was 18 years old with my OW and then AOW with PADI. I was diving with lots of friends in the late 80s and early 90s and then moved onto Kayaking. I got my daughter into diving when she turned 14 and have picked up where I left off.
I have approx 5000 dives now and spend most of my free time diving.
Here are my certs:
- OW – AOW 1989
- Adv Nitrox / Deco 2020
- Cavern – Intro Cave 2021
- CCR Tech – Fathom – 2021
