This claim is surprisingly hard to confirm or refute. The trouble is, 
there are many, many different ways to measure how salty something is. 
Consequently, I'm struggling to find anything that quotes the two 
measurements in the same units, or even using the same dimensions.

Regardless, I'm still waiting to hear why the hell the sea has *any* 
salt in it to start with... I never did understand that part.
