Rare Earth, Trace Metal, Phosphorus, and Base Cation Concentrations During Three High-Flow Events in a Headwater Stream in Vermont, USA.

The USGS team measured base cations, aluminum (Al), iron (Fe), manganese (Mn), rare earth elements (REEs), dissolved organic carbon (DOC), major anions, and phosphorus (P) in eight streamwater grab (manual) samples during each of three high-flow events (E-1, E-2, E-3) at the forested headwater catchment W-9, Sleepers River, Vermont, USA. E-1 was a large fall rainstorm, E-2 was a multi-day snowmelt, and E-3 was a small late-summer storm. The eight samples from each event were speciated for total (unfiltered-acidified) and dissolved (0.45 µm filtered-acidified) fractions.
