"Notes: Alk = alkalinity, and Sal = salinity. IW = interstitial water, HP = high pressure, and LP = low pressure. * = values have been corrected for seawater contamination (see ""Inorganic Geochemistry"" section, ""Site 994"" chapter, this volume). "															
"The depth listed for Core 164-995A-52P, a water core, is the bottom of the pipe depth at this core."
