Notes: IW = squeezed whole-round sample. ND = not determined. BDL = below detection limit (average blank plus three times the standard deviation of multiple blank measurements; Li+ = 0.1 µM, B = 0.2 µM, Mn2+ = 0.09 µM, Fe2+ = 0.03 µM, Sr2+ = 1 µM, Ba2+ = 0.08 µM). H4SiO4 values measured by different techniques during Expeditions 320 and 321 disagree significantly, especially for low values. Therefore, caution should be used concerning the H4SiO4 data and comparison between the different expeditions. See "Geochemistry" in the "Methods" chapter for uncertainty estimates and assessment of accuracy.
