DOM Contents in Estuaries
DOC concentrations in estuaries are often lower than in lakes all over the world.
They reach 84–473 μM C in China (Chen and Gardner 2004; He et al. 2010);
283–558 μM C in Brazil (Dittmar and Lara 2001); 190–2046 μM C in the USA

Fig. 2 Box and whisker-plot of the distribution of DOC concentration (a) for all lakes, (b) for
lakes divided into different land-cover types, and (c) for lakes in Saskatchewan, Canada. In (b),
the land-cover types have been sorted according to the average mean annual temperature. The
boxes display the median and the quartiles, the whiskers represent the 10 and 90 % percentiles,
and the points represent the 5 and 95 % percentiles. Only land-cover types containing 10 or more
lakes are shown. The land-cover types “inland water” and “sea water” are omitted from the plot
because they are not indicative of climate or geography. Data source Sobek et al. (2007)
