Well I searched and searched and other than Joly’s research (1901) I couldn’t find anything else on historical salinity levels. Although, if ocean salinity is slowly declining, or even remaining constant, then it does raise an interesting question as to how the ocean achieved its current salinity levels. Having said that, and given the paucity of research on the subject, there are probably too many factors that play into regulating salinity to speculate further about the subject. I therefore retract my previous statement pending further evidence—GGG

My sincere congratulations!
