Notes: * = calculated from bottom-water temperatures of 1.67° to 1.78°C and the temperature gradients in Table T18. Methods: ISE = ion-specific electrode, ET = electrochemical titration, IC = ion chromatography, Calc. = calculated, CT = colorimetric titration, Color = colorimetric spectrophotometry, ICP-AES = inductively coupled plasma-atomic emission spectroscopy. WSTP = water sampling temperature probe. † = because HS- in the samples was titrated by AgNO3 along with chlorinity, all values used are chloride as measured by IC, except for the WSTP sample and for those 15 samples (mainly from Hole 1200D) for which the chlorinity by titration was smaller. ‡ = calculated from charge balance; these values average 2% higher than Na by IC, because chloride by IC is 1% too high and Na by IC is 1% too low. See "Chloride, Sulfide, Sodium, Alkalinity, and Sulfate: An Analytical Note" in "Interstital Waters" in "Geochemistry." ** = Section 195-1200D-5H-1 was disturbed and obviously contaminated with seawater, probably during recovery. Changes observed relative to seawater should be considered minima.
