A simple concept model of the climatology of a subtropical ocean gyre is developed on the basis of assumed isopycnal transport and latent heat flux. The 27 year record of annually averaged salinities on isopycnals near Bermuda shows clear and systematic variations, and significant (> 95% confidence) correlations with oxygen (positive) and vertical density gradient (negative) support the hypothesis....
