Dissolved iron concentrations of the initial water prior to the experiment

This table shows the dissolved iron concentrations of the initial water prior to the experiment (Initial) and after the incubation with salp and krill fecal pellets in filtered seawater (FSW) and seawater containing phytoplankton (SWP) as well as respective controls. Numbers marked in red have been recognized as outliers (due to contamination or analytic error) and have been excluded from statistical analysis.
