NEON prototype reaeration data from Kings Creek STREON site (STKG), 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](https://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](https://data.neonscience.org/api/v0/documents/NEON.DOC.000693vH).本数据产品包含经过质量控制的原生采样分辨率数据集，源自国家生态观测网络（National Ecological Observatory Network, NEON）的可涉水溪流复氧采样规程。在NEON水生监测站点，研究人员会在持续注入惰性气体六氟化硫（SF₆）与保守性示踪剂（氯化钠NaCl或溴化钠NaBr）的溪流下游4个采样点位采集河流水质瞬时水样。示踪剂注入前需采集本底水样，用于分析盐类示踪剂的本底浓度。当示踪剂浓度达到稳定状态（通过电导率测定）后，采集平台期水样，每个采样点位采集5份平行样，分别用于盐类与气体示踪剂的浓度分析。数据使用者可参考《基于复氧与盐类的径流计算用户指南（NEON_ReaerSaltBasedQ_userGuide_vA）》（https://data.neonscience.org/api/v0/documents/NEON_ReaerSaltBasedQ_userGuide_vA），获取从已发布数据包中计算复氧速率的相关指导。如需了解NEON野外与实验室规程的更多细节，请查阅《大气与陆地观测系统规程与流程：溪流复氧（NEON.DOC.000693）》（https://data.neonscience.org/api/v0/documents/NEON.DOC.000693vH）。
