Reaeration field and lab collection (DP1.20190.001)

This data product contains the quality-controlled, native sampling resolution data from NEON's wadeable stream reaeration sampling protocol. During most reaeration experiments, 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 see `NEON_ReaerSaltBasedQ_userGuide` for suggestions on how to calculate reaeration rates from the published data packages. For additional details, see the user guide, protocols, and science design listed in the Documentation section in this data product's details webpage. During some reaeration experiments, denoted by injectionType “model - slug” or “model - CRI”, only the conservative tracer is injected, either via slug or constant rate, (i.e., inert gas is not injected). See NEON Data Product User Guide to Reaeration (DP1.20190.001) and Salt-based Discharge Sampling (DP1.20193.001) for more detail about when and where model type injections are used.

Latency:
The expected time from data and/or sample collection in the field to data publication is as follows, for each of the data tables (in days) in the downloaded data package. See the Data Product User Guide for more information.
