Lake water chemistry was measured for lakes in Iceland. 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 a February field campaign. Additionally, 0.5-1L grab samples of surface 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).
