Measuring and modeling the lock 23
Mesurer une structure longue d'un kilomètre, enfouie à 40 pieds (12 m) sous la surface du fleuve Saint-Laurent...
Pourquoi s'attaquer à un projet aussi fou?
Comment s'y prendre?
Quels mesures prendres?
Quels sont les défis pour le plongeur?
Comment effectuer des mesures dans un site marqué par le courant?
Comment réaliser entièrement son plan de mesurage tout en faisant une plongée sécuritaire?
To challenge oneself
While it would have been interesting to discover the ghost vehicle, Christian is not disappointed as he paddles towards the exit point.
He has found something much better…
Jean-Louis Courteau wrote an excellent article Se mesurer à soi-même (in french) in the magazine En Profondeur which tells the story of the genesis of the project and the personal challenges I had to face as a diver.
