I will have to look up the various ion concentrations in sea water 
(common ranges really), but memory suggests that they are mostly alkali 
metal cations and halogen anions. Neither of these groups or ions is 
going to have an appreciable buffering effect. The only common 
inorganic ion I can think of at the moment which will have buffering 
effect is phosphate, which will frequently be precipitated out by many 
alkline earth cations and transition metal ions.

Sorry - forgot the bicarbonate ion, which will buffer in the pH 7 
region. I don't know concentrations however.
