Figure 4
Sea ice nutrient concentrations in relation to salinity. Concentrations of (a) NOx and (b) NH4+ versus bulk salinity in sea ice prior to the complete brine drainage event. The solid line indicates the expected dilution line predicted from salinity and nutrient concentrations in seawater (15 m depth, salinity of 33). Values below the dilution line indicate nutrient depletion; values above it indicates either production or net accumulation. Data points represents treatment mean ± SD (n = 3).
