Susquehanna Shale Hills Critical Zone Observatory - 2016 high-frequency water chemistry of the Shale Hills catchment

Abstract: Streamwater and groundwater samples were collected at relatively high frequencies using ISCO water samplers 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 samples were acidified using ultra-pure nitric acid (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，采用ISCO水质采样器（ISCO water samplers）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样进行过滤。所有样品均使用体积分数2%的超纯硝酸完成酸化处理。本研究由美国国家科学基金会（NSF）关键带观测计划资助，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。
