Description: 

"Estimated analytical uncertainty (1 standard deviation) on dFe-corr as estimated from the percent relative standard deviation (RSD) on the mean of repeat determinations of the SAFe seawater reference materials S and D2 (details are presented under the heading 'Dissolved iron analysis' under 'Acquisition Description'). A linear fit of %RSD versus reference seawater concentration is used to estimate RSD values for dFe-corr values of less than or equal to 0.96 nM [equation: %RSD = 15.5 - 6.66(dFe-corr)] whereas a constant RSD of 9.2% is applied to dFe-corr values > 0.96 nM.
