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.
