Have you got a source for that information? I don't have the figures
in
front of me, but I believe your "volcano output" figure is not factoring
in
major eruptions that alone can (and often do) put out an incredible
amount
of emissions.

'I'm feeling lucky' on Google brings the following reference.

From the University of North Dakota:
http://volcano.und.edu/vwdocs/Gases/man.html

"Most of the gases emitted by the ocean return to the oceans."

No support given for this assertion. It's also possibly bogus.

I notice they also used averages from just a couple volcano's including a
couple that a relatively "clean".
