Title: Wood Science
Post by: Forester Frank on February 01, 2001, 08:55:37 AM
Question for all members of the forum?

Does wood float?

Analytical thinkers welcome.

Only if the specific gravity is less than that of water.

Of course that is dependent on the amount of air space in the wood itself.

I remember hearing that in SE Asia, they have to cut the trees, and allow them to dry before then can raft them downriver.  Can't remember the species.  Teak?

Frank,
Have you read the book Underwater Logging?

Ron, I see on your website That ARC does underwater mapping and surveys. That sounds interesting, do these services sometimes have something to do with underwater logging? Why would you need underwater mapping other then obvious reasons such as depths for navigation and such?

I co-authored the book Underwater Logging with master diver Jack Cayford of Bangor Maine, published by Cornell-Maritime Press back in
1964. It has to with underwater log salvage which I did back in the 1960's and still consult some on.
The underwater surveys has to do with mapping bottoms, checking dams and bridge footings, fish habitat structures, municipal water systems, zebra mussels, archaeological surveys, shipwrecks, etc. I'm not as active as I use to be in this though as age creeps up on me.

I knew you guys would get this one. I was looking for an answer that had to do with woody cell structure and air space and specific gravity. Thanks.
