Water chemistry from the Red River Delta, Vietnam, 2018 to 2020

The dataset contains physical, chemical and biological measurements from the waters of 21 river sites across the Red River Delta in northern Vietnam. The data were collected monthly between February 2018 and January 2020. The parameters include temperature, dissolved oxygen, salinity, pH, turbidity, conductivity, total dissolved solids, dissolved nitrate, dissolved nitrite, dissolved ammonium, total nitrogen, dissolved phosphate, dissolved silicate, alkalinity, dissolved major ions (sodium, magnesium, potassium, calcium, chloride, sulphate) and a range of chlorophyll and carotenoid pigments from riverine seston.

该数据集收录了越南北部红河三角洲21个河段的水体物理、化学和生物测量数据。数据采集自2018年2月至2020年1月，每月一次。参数包括温度、溶解氧、盐度、pH值、浊度、电导率、总溶解固体、溶解硝酸盐、溶解亚硝酸盐、溶解铵、总氮、溶解磷酸盐、溶解硅酸盐、碱度、溶解主要离子（钠、镁、钾、钙、氯、硫酸盐）以及河流浮游生物中的多种叶绿素和类胡萝卜素色素。
