Spatial distributions of DOM quantity and quality parameters (a) DOC, (b) DON, (c) a ₂₅₄, (d) HIX, and (e) FI over the two-year study period (2008-2009) across watershed compartments. Red lines in the box-plot represent median values and red-filled circles represent mean values connected with broken red lines. Empty circles represent outlier data points. (a), (b), and (c) are log-scaled data for 𝑦-axis to capture distinctiveness in data.
