(Table S1) Seasonal oxygen, nutrient, Mn, and Fe data for intertidal pore waters and adjacent seawater of Spiekeroog Island North Beach (Germany)

Nutrient values below limit (#99) of quantification, but above limit of detection are shown as second values. All Nutrients were filtered by 0.45 µm. The actual limit of quantification is assumed to be lower than the operationally defined limit of quantification (lowest calibration point).
