Johann convinced Nargeolet to write his book 'In the depths of the Titanic' because he said his kids were super-fans. The underwater explorer needed convincing to write a book, Johann said, because he wanted to spend all of his time diving. CAREER IN FRENCH NAVYDirector of underwater research for RMS Titanic, which owns the rights to the ship's remains, Nargeolet started researching and exploring the Titanic wreck when he joined the French ocean research institute Ifremer in 1986, after a 22-year career in the French navy. They met after Marsh contacted the explorer to ask for the contact of a Frenchman who had survived the Titanic. The president of RMS Titanic, Jessica Sanders, said in a statement on Wednesday that Nargeolet's experience was unparalleled and "no-one has a better chance of navigating equipment failures than he does".
