Hi Guys.. I'm an Ambergris Broker here in NZ, i also look for Ambergris in NZ & oversea's as well as being involved in some other more commercially sensitive aspects of Ambergris in the perfume world, and i also look for (sinking!) gold as more of a hobby.
Floating Gold is a good read, I know Chris Kemp (i actually sent him his first piece of 'gris before his book came out) pretty well, but if you're expecting a manual on how to look for it then forget it - this is a book on the history and uses, but still very interesting, although theres things about ambergris that i know that Chris would proberly never be privy to.
Ambergrising is a pretty secretive industry (a few of us were approached by Discovery Channel a couple of years ago resulting in a Pilot, but in the end it never flew) with most people that dont know anything about it wanting to talk all day about it, and those those know lots about it not wanting to talk at all!
However I can be pretty open about some aspects of it as i cant be on every beach in NZ and as a Broker i would rather someone find it that is a friend than a stranger out of my loop.
For example i told a host i met in an Air B&B in Bristol UK about it last year, showed him some and a few months later he was in Iceland and found an awesome piece!
Its certainly a very interesting substance, with a few thousand years of human use and understanding, and having many uses in food, alcohol (and yes, even smokable!) but its rarer than rocking horse shit - only made by Sperm Whales, and only by Males, and only by BIG males, there maybe a few hundred whales on the whole planet that make it.
But, much like gold, its a great excuse for getting out there into some beautiful remote places and blending work & madventures together til ya cant tell the difference.

(gold 'n gris that is)
