Notes: * = Based on a bottom-water temperature of 1.51ºC and a linear extrapolation from a measured temperature of 7.08ºC at 44.6 mbsf in Hole 1201C. Methods: ISE = ion-specific electrode, ET = electrochemical titration, IC = ion chromatography, CT = colorimetric titration, Color = colorimetric spectrophotometry, ICP-AES = inductively coupled plasma-atomic emission spectroscopy. † = 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. ‡ = as measured by IC; these two samples were too small to analyze by other methods.
