Hmmmm, well after exploring, I'm very disappointed. That docstoc site is a jumble of tertiary sources and opinion (wrong & right); and that biocab site is just too unique to be the final word.

I may be able to trace some of the Docstoc sources back; and biocab cites Stephen Schwartz's paper (that we've cited a few months ago, along with Levitus), so that's cool... good potential leads.

I'll see what I can find at the library about heat.
It may be a few days....
