Table 2 Solute concentrations and DOM molecular composition of the reference (Chilnualna) streamwater in Yosemite National Park, California, USA. Streamwater was sampled from the reference site >100 years after the last fire. Values shown are means ± (standard error)

From: Fire severity, time since fire, and site-level characteristics influence streamwater chemistry at baseflow conditions in catchments of the Sierra Nevada, California, USA
