Notes: BDL = below detection limit (HPO42– = 0.4 µM, Mn2+ = 0.1 µM, Fe2+ = 0.2 µM, B = 1.4 µM, Sr2+ = 0.2 µM, Ba2+ = 0.7 µM, Li+ = 0.4 µM). H4SiO4 values measured by different techniques during Expeditions 320 and 321disagree significantly, especially for low values. Therefore, caution should be used concerning the H4SiO4 data and comparison between the different expeditions.
