NEON prototype reaeration data from Walker Branch STREON site (STWA), 2015

This data product contains the quality-controlled, native sampling resolution data from NEON's wadeable stream reaeration sampling protocol. Grab samples of stream water at NEON aquatic sites are collected in streams at 4 sampling locations downstream of a continuous injection of an inert gas (SF6) and conservative tracer (NaCl or NaBr). Background samples are collected prior to tracer injection and are analyzed for background salt tracer concentrations. Plateau samples are collected once the tracer concentration reaches a constant concentration (as measured by conductivity) and 5 replicate samples from each station are analyzed for both salt and gas tracer concentrations. Data users should refer to the user guide for reaeration and salt-based discharge ([NEON_ReaerSaltBasedQ_userGuide_vA](http://data.neonscience.org/api/v0/documents/NEON_ReaerSaltBasedQ_userGuide_vA)) for suggestions on how to calculate reaeration rates from the published data packages. For additional details on NEON field and laboratory protocols, see the AOS Protocol and Procedure: Reaeration in Streams [NEON.DOC.000693](http://data.neonscience.org/api/v0/documents/NEON.DOC.000693vH).
