a Boxplot combined with a dot plot. The box is formed by the first and third quartiles while the whiskers extend to 1.5 times the inter-quartile range. The data points in the Baltic surface seawater left of the whisker indicates outliers. The environments are ordered according to increasing depth although they do not represent a physical continuum due to the multiple sampling sites as shown in Fig. 2a. Scatterplots depicting the relation of alpha diversity with depth (b) and with dissolved organic carbon (c). Shading in b, c represents a 95% confidence interval.
