Salinization as a driver of eutrophication symptoms in an urban lake (Lake Wilcox, Ontario, Canada)

In this study, we identified the mechanism(s) responsible for the intensification of eutrophication-like symptoms in Lake Wilcox, using statistical analysis (Principal Component Analysis (PCA) and Multiple Linear Regression (MLR)) of water chemistry timeseries. The dataset contains changes in nutrient concentrations in Lake Wilcox; changes in ratios between phosphorus (P) species and P and nitrogen (N) species; changes in the Brunt-Väisälä frequency (which represents the amount of work required against gravity to break down thermal stratification in the water column); and the results of the PCA and MLR statistical analyses. The methods used to derive this dataset and the interpretation of the dataset are reported in the paper "Salinization as a driver of eutrophication symptoms in an urban lake (Lake Wilcox, Ontario, Canada)" from authors Jovana Radosavljevic, Stephanie Slowinski, Mahyar Shafii, Zahra Akbarzadeh, Fereidoun Rezanezhad, Chris Parsons, William Withers, and Philippe Van Cappellen.

本研究通过对威尔科克斯湖（Lake Wilcox）的水化学时间序列开展主成分分析(Principal Component Analysis, PCA)与多元线性回归(Multiple Linear Regression, MLR)等统计分析，明确了导致该湖类富营养化症状加剧的作用机制。本数据集涵盖威尔科克斯湖的营养盐浓度变化、磷（P）各形态间以及磷与氮（N）各形态间的比值变化、布伦特-维萨拉频率(Brunt-Väisälä frequency，其代表为打破水体热分层所需克服重力做的功)，以及主成分分析与多元线性回归统计分析的结果。本数据集的构建方法与解读方式已发表于论文《盐渍化作为城市湖泊富营养化症状的驱动因子——以加拿大安大略省威尔科克斯湖为例》("Salinization as a driver of eutrophication symptoms in an urban lake (Lake Wilcox, Ontario, Canada)")，作者为Jovana Radosavljevic、Stephanie Slowinski、Mahyar Shafii、Zahra Akbarzadeh、Fereidoun Rezanezhad、Chris Parsons、William Withers及Philippe Van Cappellen。
