Notes: — = no data. BDL = below detection limit (HPO42– = 0.6 µM, Mn2+ = 0.4 µM, Fe2+ = 0.4 µM, B = 4 µM, Sr2+ = 0.6 µM, Ba2+ = 0.1 µM, Li+ = 1.4 µM) calculated as three times the standard deviation of multiple measures of a blank. 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.
