用于部署水质传感器的基础设施的设计可能会影响数据质量。尽管如此，传感器基础设施设计尚未在同行评审文献中得到充分讨论。在这里，我们展示了两种对比设计的并排测量结果；一个“独脚架”，由一个打入河床的支柱和一个悬挂在“架空电缆”上的下行支架组成。我们从国家生态观测站网络内的两个可涉水溪流监测点收集了大约 6 个月的测量数据。一般来说，我们观察到测量之间的差异很小，这表明从数据质量的角度来看，两种设计在正常操作条件下都是可行的选择。然而，独脚架设计更容易在低阶段从水中浮出并被沉积物掩埋。虽然安装成本更高且逻辑复杂，但架空电缆设计表现出更高的耐用性、可调节性和可维护性。我们讨论了额外的设计考虑因素和潜在的修改，我们希望这些修改对其他研究人员在他们自己的站点上进行仪器仪表化有用。
The design of infrastructure used for deploying water quality sensors can potentially impact data quality. Despite this, sensor infrastructure design has not been well discussed in the peer‐reviewed literature. Here, we present side‐by‐side measurements from two contrasting designs; a “monopod” consisting of a strut driven into the streambed and a downrigger suspended from an “overhead cable.” We collected measurements over an approximately 6‐month period from two wadeable stream monitoring sites within the National Ecological Observatory Network. In general, we observed minimal differences between measurements, suggesting both designs to be viable options from a data quality perspective under normal operating conditions. However, the monopod design was more susceptible to coming out of the water during low stage and burial by sedimentation. While more expensive and logistically complex to install, the overhead cable design exhibited greater survivability, adjustability, and serviceability. We discuss additional design considerations and potential modifications that we hope will prove useful to other researchers in instrumenting their own sites.
