New Hampshire EPSCoR Intensive Aquatic Network continuous Discharge, Nitrate, fDOM, Temperature, and Specific Conductance Data

Continuous data is collected at 9 sites throughout New Hampshire. At each site data is collected every 15 minutes by the datalogger from a HOBO Stage logger (or site is paired with USGS site), Satlantic SUNA and YSI EXO2. Data is collected and transmitted to UNH by cell telemetry once a day where it is stored on the NH EPSCoR data server. The data that is collected from the SUNA are Nitrate in mg/L and is corrected by grab sample NO3 analyzed by IC. Data that is collected by the YSI are Stream Temperature, Specific Conductance, and fDOM in QSU. The fDOM is corrected by temperature, turbidity (not included), and absorbance.

This data set was used to analyze the high-frequency time series of stream solutes to characterize the timing and magnitude of nutrient and organic matter transport over event, seasonal, and annual timescales as well as to assess to whether nitrate (NO3-) and dissolved organic carbon (DOC) transport are coupled in watersheds. Our dataset includes in situ observations spanning 2 – 4 years in 10 streams and rivers across New Hampshire, including observations of nearly 700 individual hydrologic events. These events are identified in the files.

Methods and findings are described in the associated WRR manuscript.

本数据集于新罕布什尔州境内九个监测点连续采集数据。各监测点通过 HOBO Stage 记录仪（或与 USGS 监测站配对）以及 Satlantic SUNA 和 YSI EXO2 设备，每15分钟自动采集一次数据。数据每日通过蜂窝遥测技术传输至新罕布什尔大学，并存储于该州 EPSCoR 数据服务器。SUNA 采集的数据为每升水中硝酸盐的毫克数，并由 IC 法分析的现场采样 NO3 进行校正。YSI 采集的数据包括溪流温度、电导率和 QSU 中的荧光溶解有机物（fDOM）。fDOM 的校正考虑了温度、浑浊度（未包含）和吸光度。该数据集旨在分析溪流溶质的高频时间序列，以刻画营养物和有机物质在事件、季节和年度时间尺度上的传输时机和强度，并评估硝酸盐（NO3-）和溶解有机碳（DOC）的传输是否在流域中呈现耦合关系。本数据集涵盖了新罕布什尔州10条河流和溪流中的2至4年现场观测数据，包括近700个水文事件的观测记录。这些事件在文件中均有标识。相关的方法和发现已在WRR手册中详细描述。
