Seasonal variations and annual concentration ratios relative to Na in horizontal deposition and in seawater.

<p>The ratios are expressed as mmol mol^-1 Na (mean ± SE; n = 7), but excluding the site closest to the coast (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0126225#pone.0126225.s005" target="_blank">S1 Table</a>). Different letters indicate significant seasonal differences (<i>P</i> < 0.05, bold text) determined using ANCOVA (categorical variable = season; continuous variable = distance from ocean) followed by post-hoc Tukey tests. There were no distance x season interaction effects on any of the nutrients except DON.</p><p>Seasonal variations and annual concentration ratios relative to Na in horizontal deposition and in seawater.
