Finished reading The Silent World by Jacques Cousteau.

It’s a bit strange in that it has no real order and is a collection of semi–related stories about the development and use of the aqualung. Very informative about some of the physiological effects of diving.

A particularly potent part is Cousteau’s story of the first time bottom trawling had ever been filmed, revealing it to be a hideously inefficient and ineffective method of trawling. No–one had ever realised before, because no one had ever actually seen a net working.
