In part one of this series, which appeared in issue #103, I suggested a few commandments to consider in order to ensure, as far as possible, that your technical dives are safe and successful. These were: First commandment: Prepare paperwork; Second commandment: Nominate a supervisor; Third commandment: Deploy safety divers. In this sequel, I deliver a few more tablets of stone.
Today, technical diving is well into its fourth decade. We now have better tools, technology and systems than we did in the past and we know far more about which methods, decompression strategies and gear configurations work well and which do not.
In the book Into Thin Air, journalist Jon Krakauer tells the story of five people who died near the summit of Mount Everest in 1996. Two were expedition leaders, one was a professional guide and two were their clients.
“Wait, wait,” you may say when you read the title of this column, “What are you talking about? Aren’t those two things the same? Isn’t a dive instructor by definition a scuba professional? And what do you mean by ‘Road’?”
What we see is that sharks are being targeted by international factory fleets around the world who trail millions upon millions of baited hooks through their realm, trawl the sea floors for rays, skates and other bottom dwellers to 4,000 metres, and slaughter them by the millions. Sharks are the only profitable prey remaining, now that ninety percent of the original (fish) fisheries are fished out.
It was a beautiful day in Indonesia’s Banda Sea. Richard rolled back into the warm waters and swam over to join his wife, Florence. After exchanging signals, they descended together, heading for a patch of bright yellow sea fans on the reef wall at 30m, where their guide had promised to show them pygmy seahorses. The guide was already there below, searching for the elusive little creatures.
In his book Sapiens: A Brief History of Humankind, historian Yuval Noah Harari traces the path left by Homo sapiens as our species spread over the world, causing the extinction of other human species and sub-species, and half of the planet’s big beasts. He describes the extinctions as happening in three waves.
Researchers have raised some eye-opening thoughts on nitrogen narcosis, showing that it is something that most divers THINK they understand but few actually do.
Do manufacturers hype junk science to sell exposure protection? The short answer is yes!
In 2014, off the Coromandel Peninsula in New Zealand, a diver on a discover scuba experience died when she became separated from her group and ran out of air. She was discovered on the surface, floating face down. The inquest found that the dive operation involved was to blame because they had failed to supervise her properly.
