Gene, you are not home and you knew all of those titles and author's by heart? Thanks - that means a lot - it shows me that those are really the ones you have gone back to over and over again.
In all fairness, I just had to remember where I posted this before, add a book and update the links. Internet access sucked here yesterday for some reason so I elected not to fight it to put in this link to where I first posted.
...but I'm a little confused about the whole "tissue compartment" thing. Which tissues? It never says. Never! Which are the slow ones and which are the fast ones? Connective? Brain? Muscle? Epithelial? I understand that it doesn't really matter as long as I understand that the ones that reach the M-values first are the ones that control the dive, but I'd love to know that stuff. Anyone know what book that that's in? Maybe the Bennet and Elliot book?
I found the diagram here useful for building a "mental model" of what this means but the compartments are theoretical not actual so this is only a representation.
M-values were first calculated by Workman in 1957 and then a method described by Braithwaite in 1972. Powell's book above is a GREAT way to wrap you head around all this and while waiting for it, Baker's paper "Understanding M-Values" is an excellent read.
Good luck!
