The incomplete recovery of large suspended particles from Niskin water sampling bottles, due to the positioning of the bottom spigots, results in underestimation of the major element concentrations in oceanic particulate material. Moreover, the effect varies for different elements; Si and Ca, elements present predominantly in large biogenic particles, are more concentrated in samples settling below the spigots.
