Dave, I agree. That task would be left to oceanographers, physicists, or math professors who want to torture students with calculus.

Amos, is that more fluff or are you asking seriously? I should suggest your local physics professor.

I would also ask your local oceanographers if the moon is what causes the Gulf Stream to flow. I don't know much about it, but your assertion seems incorrect somehow. I suspect other factors are at play for the Gulf Stream to exist.
