Salinity and major ion composition in United States lakes and their natural and human drivers

This dataset includes salinity and major ion data and their natural and human drivers for lakes across the conterminous US. The data were collected for and analyzed in the paper: Sun, X., Cheruvelil, K.S., Hanly, P.J., Webster, K.E., & Soranno, P.A. Natural and human drivers of salinity and major ion composition in United States lakes. Under Review. The conductivity data all factors untrans.csv dataset contains salinity (as in specific conductance) and untransformed natural and human factor data for 9,785 lakes. The ion cluster data all factors untrans.csv dataset contains major ion concentrations (in ion equivalent concentration, ueq/L), the cluster each lake was assigned to, and untransformed natural and human factor data for 1,218 lakes. Detailed explanations of each variable and data sources can be found in the metadata file and the supplementary Table S1 of the manuscript. The code.R file contains R codes applied to analyze the data.
