Beyond Climate Warming: How Salinization Accelerates Deoxygenation in Lakes

This dataset provides a harmonized collection of lake- and watershed-scale attributes, time series, and analysis code used to evaluate salinization-driven deoxygenation in lakes across Canada and the contiguous United States. It includes a lake attributes table for 144 study lakes (coordinates, morphometry, residence time, stratification metrics such as BVF(t,S), and deep-water chemistry including hypolimnetic Cl/SC and DO), together with linked watershed descriptors derived from HydroLAKES, GLOBathy, BasinATLAS and global land-use/land-cover products (population density, fraction urban, road density, watershed-to-lake area ratio, climate statistics, and snow cover). Annual mean hypolimnetic DO and salinity proxies are provided for each lake for 1988–2022, along with a companion time-series_plots folder (zip file) containing 144 lake-specific JPG figures that visualize these trends. A separate table lists HydroLAKES waterbodies in Canada and the United States predicted to be at risk of salinization-driven deoxygenation based on the logistic-regression framework described in the associated manuscript. The repository also includes the core Python scripts used for data pre-processing, geospatial extraction, clustering, statistical analyses, and figure generation, enabling users to reproduce and extend the workflows.
