I just finished reading "The Silent World" written by Jacques Cousteau and originally published in 1953. I'm sure many of you have read it but for those that haven't be sure to add this to your book list.
I'm sure it was written with the non-diver in mind but I think it's even more interesting to read as a diver and the more experience you have I think the more you will appreciate it. Not because it's a difficult read. It's the opposite but the more you know the more of the finer details you will appreciate.
One review mentioned that it was a classic but that one would not learn the mechanics of diving from this book and that it was more poetic than hands on. This is true but I don't think anyone reads a book written in the 50's to pick up dive tips for today. The more you know about diving however the more you will appreciate what was and was not known in those days. Much was known.
One interesting aspect to the book was that Cousteau was told it was OK to use an oxygen rebreather to 45 fsw or something like that. He did and almost passed out.
However, when they dove on air to 300 fsw and almost passed out and one team member did pass out and died ...the lesson that they took from this was that at 300 fsw nitrogen narcosis was so bad that a man could relax and let go of his mouth piece.
They didn't seem to know about oxygen toxicity even though the science world probably did know about it (I haven't done any research for this book review so I don't know for sure)
I do remember reading before I got this book that the limiting factor for diving in the early days wasn't the regulator but rather the technology to make higher pressure tanks. This was apparent when reading the book since Cousteau mentioned that each of their three tanks held enough air for the air to weigh about 3 lbs. So since we know that an aluminum 80 holds 6 lbs...they were using 40 cu ft tanks.
They used 3 of them however so they, like us, were diving with 120 cu ft!
It's amazing that any of them survived their "experiments". They wanted to determine how close a diver could get to a charge (mine) that was being detonated...you can see where this is going...they practically killed themselves finding out.
They learned about caves, depth, and nitrogen narcosis the hard way as well.
There was a lot that they did know and I won't recount all that here. It is interesting that, at least as of 1953, with all of their many hundreds of dives that they never saw any larger animal in the process of eating while underwater including octopus, eels, and even most fish. Even I have seen those things.
They did say that the more they learned about sharks the less they really knew. For a long time they never encountered any that were aggressive until one day they did and almost weren't able to get out of the water to tell about it.
The hardcover version of this book is only about $16 so it's very affordable and I think anyone would enjoy reading it.
