The Acid Sensitive Lakes Study in the Atlantic Canada was initiated in 1983 by Environment and Climate Change Canada, to evaluate the impact of acid atmospheric pollutant on aquatic ecosystem. Originally, the study focused on the aquatic and terrestrial effects of acid precipitation, but now it...

WCPS-coupled forecast is the component in the Water Cycle Prediction System (WCPS) that provides the coupled atmosphere-ocean-sea ice forecasts at a 1km resolution (0.008 x 0.008 degree) over the Great Lakes, St. Lawrence River and the Gulf of St. Lawrence. It launches 4 times a day at 00, 06,...

Historical water quality data measured on a continuous basis at over 23 locations across Canada is included in this dataset. Most locations include hourly temperature, dissolved oxygen, pH, specific conductance and turbidity. Data are collected by Environment and Climate Change Canada (ECCC) and...
