Susquehanna Shale Hills Critical Zone Observatory - 2017 high-frequency water chemistry of the Shale Hills catchment

Abstract: Streamwater and groundwater samples were collected at relatively high frequencies using ISCO water samaplers in the Shale Hills catchment in the Shale Hills Critical Zone Observatory. The ISCO samplers were equipped with a gravitational filtration system, which filters water upon sampling by gravity. All the samaples were acidified using ultra-pure nitric aicd (2% v/v). This work was funded by NSF Critical Zone Observatory program grants to C. Duffy (EAR 07-25019) and S. L. Brantley (EAR 12-39285, EAR 13-31726).

摘要：在页岩山地关键带观测站（Shale Hills Critical Zone Observatory）的页岩山地流域内，研究人员采用ISCO水质采样器以较高频率采集了地表水与地下水样品。该ISCO采样器配备重力过滤系统，可在采样过程中通过重力作用对水体进行过滤。所有采集的样品均使用体积分数为2%的超纯硝酸进行酸化处理。本研究受到美国国家科学基金会（National Science Foundation, NSF）关键带观测计划项目资助，资助项目编号分别为授予C.达菲的EAR 07-25019，以及授予S.L.布兰特利的EAR 12-39285、EAR 13-31726。
