[Radical new theory suggests Earth's magnetism may be linked to movement of ocean currents] - Daily Mail - June 15, 2009
An interesting read, especially as it relates to what we might see on Mars, if we could somehow melt the oceans. Would the seas be deep or extensive enough to provide a magnetosphere?
Radical? New? http://www.geomag.us/info/Smaus/Doc/ocean_encycl.pdf

Yeah, that's what I thought, but it's still an interesting idea when applied to a frozen Mars.
Perhaps I should have also said, haven't I read this somewhere before?
