Physicochemical data from six sites along the Sipsey River, AL, USA.

“Surface” measurements reflect readings from the water column and “pore” reflects porewater readings. Sites are ordered moving downstream and the distance from the first site is noted. Three measurements of each environmental parameter were recorded between June 9 and September 28, 2016. Data shown reflects the means of these three measurements and the standard error.

表层（Surface）测量值对应水柱的实测数据，"孔隙（pore）"则代表孔隙水的实测数据。采样点位按顺流方向排序，并标注了各点位与首个点位的距离。2016年6月9日至9月28日期间，针对每项环境参数开展了三次重复测量。本次展示的数据为该三次测量的均值及其标准误（standard error）。
