(Table 2a) Determination of ligand characteristics in unfiltered samples taken during POLARSTERN expedition ARK-XXII/2 - determination of an upper limit using total dissolvable iron@en

The standard deviation for Fe concentrations is missing when there were not enough samples to determine the concentration in duplicate or triplicate. Modelled values missing when the model could not fit the data using the upper limit.当样本量不足以通过平行双样或平行三样测定浓度时，铁（Fe）浓度的标准差数据缺失；当模型无法利用上限值完成数据拟合时，模型拟合值缺失。
