Chemistry of Streamwater at the Hubbard Brook Experimental Forest, Watershed 3, 1963 - present

Streamwater chemistry has been measured at the Hubbard Brook Experimental Forest since 1963. These data include volume-weighted, average, monthly concentrations of cations, anions, and pH measured in 9 watersheds. Monthly averages are calculated from samples collected at weekly intervals from a point above the stream gauging station.自1963年起，科研人员便在哈伯布鲁克实验林（Hubbard Brook Experimental Forest）对溪流河水化学组分开展长期监测工作。该数据集涵盖9个流域的体积加权月平均浓度数据，监测指标包含阳离子、阴离子与pH值。月平均值由每周采集的水样计算得到，采样点设置于溪流测流站上游位置。
