Interstitial water samples from seven ODP sites (Leg 181, Sites 1119^1125) of the southwestern Pacific Ocean have been analyzed for the stable sulfur isotopic composition of dissolved sulfate along with major and minor ions. Sulfate from the interstitial fluids (N 34 S values between +20.7 and +60x
