Public interest in the deep ocean went into a frenzy this week as the search for the doomed Titan submarine played out – and Oscar-winning film director has made no secret of the fact that he is obsessed with the subject. Since it emerged on 22 June that the Titan was destroyed in what US authorities called a “catastrophic implosion”, Cameron has been telling media outlets that he knew what the five-man crew’s fate was since Monday, four days earlier. After calling up his “contacts in the deep submersible community” Cameron said he had already ascertained that the vessel had been destroyed in an implosion. “I felt in my bones what had happened.” Sign up to our free Indy100 weekly newsletter But why does Cameron know so much about the ocean depths? Titanic, Avatar and The Abyss First of all, Cameron has made a lot of films about the bottom of the sea. His 1997 film, Titanic, won 11 Oscars and was the first movie to earn more than $1bn worldwide, and Cameron went deep on his research – literally. The filmmaker has visited the real-life wreck of the Titanic 33 times, making his first trip in 1995 to shoot footage for the film. One of those dives even involved getting trapped with the wreck for 16 hours, with currents of water holding the director’s submarine at the bottom of the ocean. He has even written a book about his experiences, Exploring The Deep, which includes details of his dive journey, photos and maps from his own explorations of the wreck. He told ABC News: “I actually calculated [that] I've spent more time on the ship than the captain did back in the day.” Long before Titanic, Cameron directed The Abyss in 1989. The premise of the film is that an American submarine sinks in the Caribbean – sound familiar? That prompts a search and recovery team to race against Soviet vessels to recover the boat. Meanwhile, the last movie in Cameron’s famous Avatar franchise, The Way of Water, is set on the aquatic ecosystems of a world 25 trillion miles from Earth. "Some people think of me as a Hollywood guy … (but) I make 'Avatar' to make money to do explorations," Cameron told The Telegraph. Going even deeper In 2012, Cameron went a step further, plunging nearly 11km down to the deepest place in the ocean, the Mariana Trench in the western Pacific. The filmmaker made the solo descent in a submarine called the Deepsea Challenger, and it took more than two hours to reach the bottom. The submarine he used was years in the making, designed by Cameron himself with a team of engineers. The trip was only the second manned expedition to the Mariana Trench. The first was in 1960, when US Navy Lieutenant Don Walsh and Swiss scientist Jacques Piccard descended to the ocean floor. “It was absolutely the most remote, isolated place on the planet,” Cameron said in a later interview. “I really feel like in one day I've been to another planet and come back.” He was even underwater when 9/11 happened His obsession with the ocean goes back to age 17, he told the New York Times, when he learned to scuba dive, when he said he felt like he had discovered the "keys to another world”. And between making Titanic in 1997 and Avatar in 2009 Cameron didn’t make a feature film. But he did make documentaries about sea exploration. One of those, 2003’s Ghosts of the Abyss, showed Cameron's travels to the Titanic, while the other, 2005’s Aliens of the Deep, saw Cameron team up with NASA scientists to explore the sea creatures of mid-ocean ridges. Cameron’s fascination even meant he was inside a submersible vessel exploring the Titanic on 11 September 2001, when terrorists flew two passenger jets into the World Trade Centre. It was only after the now-68-year-old director and his crew finished their expedition and returned to the main ship that Cameron learned what had happened. “What is this thing that’s going on?” Cameron asked the late actor Bill Paxton, who played treasure hunter Brock Lovett in the film. “The worst terrorist attack in history, Jim,” Paxton said. Cameron realised he “was presumably the last man in the Western Hemisphere to learn about what had happened,” he told Spiegel in 2012. Have your say in our news democracy.

Australia get away with it, Ireland will feel they should have got something. Both can take some encouragement from their opening game of the Women’s World Cup, while England can take encouragement from how beatable these possible last-16 opponents look. This absorbing first game for the co-hosts was so much more engaging than a single penalty from Steph Catley and a narrow 1-0 suggested. Some of that might have been down to Sam Kerr’s injury for the opening two matches. The truth is it makes Australia a completely different team. That’s also why it could have been a lot worse for the hosts. A proud if frustrated Ireland would have felt they should have had so much better, though. Many would certainly have expected worse going into this game. Australia have been seen as potential champions, a huge wave behind them, and significant momentum. That might return with Kerr, but it is for now a disruption, an uncertainty. It also can’t be discounted that nerves could have added to that. The context was key to all of this. This was the biggest match the hosts had ever played, the move to Stadium Australia symbolising that. It was also the biggest match Ireland had ever played, since it was their first ever World Cup game. They rose to that to add to Australia’s issues. Ireland have always been a defensively drilled team under manager Vera Pauw but, as befitting the occasion, there was an escalation. It wasn’t just the team giving more. There was more to the approach. It often felt as if a good defensive unit evolved into systemic hard challenges, reminiscent of a Diego Simeone side. Australia, already missing Kerr and the manner she naturally links the entire team together through her central attacking role, were further disrupted and broken up. There was little fluency to their play. There couldn’t be. Ireland were too disruptive. Louise Quinn was one of a few Irish players meeting everything at the back but it went right up the pitch. Arsenal’s Katie McCabe was typically willing to lead the way. She was so committed she suffered injury to her fingers, but was also fortunate not to be further sanctioned for a particularly abrasive challenge on Hayley Raso. Their encounters on the left developed into a proper battle, mostly in the right way - although not without some edge. The issue was maybe how the use of McCabe took away from some of her edge, but it was necessary against a superior side. It just always carries some risks of its own. There was almost a Chekov’s tackle just before half-time, when Marissa Sheva went in very heavily on Katrina Gorry. Ireland were always on the brink of giving something more on way, even as they attempted to give up no space. The only surprise was maybe how early it came, given that it looked like it was going to become one of those matches where the home side were forced to the limits of their patience. As it was, shortly after half-time, Australia lofted a ball forward. If Raso’s position in the box was anticipated, less likely was that it was Sheva marking here. The forward had her hands all over Raso’s back and the Australian finally had the recompense for a lot of punishment in the game. Her team had a badly needed penalty. Catley stepped up, the atmosphere suddenly ratcheting up. The delay only added to the nerves. Catley didn’t show any. She hammered the ball right into the top corner. Australia had their reprieve and, temporarily, enjoyed a release. There was an extended spell when they were enjoying much more space around the Irish box. That only served to show, however, how much they miss Kerr. Australia had about 10 minutes when Ireland looked affected by the goal but couldn’t maximise it. Pauw’s team in turn sensed this and really picked it up. They began to get at the hosts, to get around them. McCabe’s superb set-piece deliveries were constantly causing problems. For one, the ball fell back to Heather Payne in a free position near the penalty aree, only for the winger to swipe at it. It said enough that Australia goalkeeper Mackenzie Arnold was already time wasting by this point. It actually meant there was more time for anguished chances for Ireland. As late as the 96th minute, the ball fell back to McCabe, only for the team leader to not fully get behind the shot. She immediately got behind a brilliant cross, though, that Louise Quinn could only head wide. Australia were relieved. Ireland could take huge pride, and they will surely challenge Canada and Nigeria for second place in this group - and maybe a knock-out game against England. Australia, however, take the three points. It’s a start. It could have been worse for the hosts, but it needs to get a lot better.
