Interstitial water studies were done at 9 of the 11 sites visited in the Mississippi Fan and Orca and Pigmy Basins during DSDP Leg 96. High concentrations of sulfate were observed at Mississippi Fan Sites 616, 617, 620, and 623. The maximum sulfate value of 38.8 mM, recorded at Site 617, is the highest ever found in DSDP sediments. Hypersaline interstitial water was observed at Site 618 in Orca Basin. Concentration ratios of salinity to chlorinity and to sodium in interstitial waters are similar to those of Orca Basin bottom water, suggesting that the chemistry of interstitial water is affected by the dissolution of buried salt. ... : Supplement to: Ishizuka, Toshio; Kawahata, Hodaka; Aoki, Saburo (1986): Interstitial water geochemistry and clay mineralogy of the Mississippi Fan and Orca and Pigmy Basins, Deep Sea Drilling Project Leg 96.
