NM, not measured.

^aDOC, dissolved organic carbon measured as the difference between dissolved non-purgable organic carbon and total inorganic carbon.

^bTotal N, total dissolved nitrogen measured as all N compounds present in sample, including nitrogen compounds in DOM.

^cWater flow rate; BDL, below detection limit for the flow meter measurement.

^dNC, not calculated because velocity measurements were below detection.

^eFI, Fluorescence index, see text for description.

^fHIX, Humification index, see text for description.

^gBIX, Biological index, see text for description.
