Water year 2019 monitoring of the inorganic carbon system (pH and total alkalinity) in the Upper Clark Fork River (Montana, USA)

These data were collected by the University of Montana and Montana State University to support the Upper Clark Fork River restoration monitoring project supported by the US NSF Long Term Research in Environmental Biology (LTREB) program. The original analytical intent for these data was to assess the response of river inorganic carbon system to the floodplain restoration. Data are lab analyses of pH and total alkalinity in samples of well-mixed river thalweg water. Data are from the 2019 water year (1 Oct 2018 to 30 Sep 2019). Data were collected on the Upper Clark Fork River (USGS HUC 17010201) at 13 project sites distributed along the river from the vicinity of Anaconda to Missoula, Montana, USA. Lab analyses include high-precision colorimetric pH analysis and gran titration of alkalinity.

本数据集由蒙大拿大学与蒙大拿州立大学采集，用于支撑由美国国家科学基金会（US National Science Foundation, NSF）环境生物学长期研究（Long Term Research in Environmental Biology, LTREB）计划资助的上克拉克福克河修复监测项目。本数据集的初始分析目标为评估河流无机碳系统对河漫滩修复工程的响应。数据为充分混匀的河流深泓水样的pH值与总碱度实验室分析结果。数据采集时段为2019水文年（2018年10月1日至2019年9月30日）。数据采集点位位于美国蒙大拿州境内上克拉克福克河（美国地质调查局水文单元代码USGS HUC 17010201）沿线的13个项目站点，覆盖范围从阿纳康达附近至米苏拉。实验室分析包含高精度比色法pH检测与碱度Gran滴定分析。
