Lake water chemistry was measured for lakes in the Eastern Canadian Arctic, primarily on Baffin Island. We used a multiparameter probe (HydroLab HL4, OTT HydroMet) to measure in situ temperature, pH, dissolved oxygen (DO), and electrical conductivity of the water column at 0.5-1 m resolution. These measurements were repeated during each field campaign, resulting in multiple years of summer water chemistry data for many lakes. For some lakes, profiles of the water column were additionally taken through the ice during May field campaigns. Additionally, 0.5-1L grab samples of surface (and occasionally middle and bottom) waters were analyzed for Total Phosphorus (mg/L), Chloride (mg/L), Nitrate (mg/L), Sulfate (mg/L), TOC/DOC (mg/L), and Total Nitrogen (mg/L).
