Physical and chemical characteristics of 1300 lakes and ponds across the Canadian Arctic
Lakes and ponds are a major feature of the Arctic landscape and are recognized as effective ‘sentinels of change’. Here we present water chemistry characteristics of lakes and ponds (n = 1300 with 26 variables) across the Canadian Arctic collated from published studies. We also extracted geological...

Lakes and ponds are a major feature of the Arctic landscape and are recognized as effective ‘sentinels of change’. Here we present water chemistry characteristics of lakes and ponds (n = 1300 with 26 variables) across the Canadian Arctic collated from published studies. We also extracted geological and ecoregion data in an attempt to determine the key drivers. In general, most lakes were shallow (85.4%, <10 m), nutrient (phosphorus) poor (oligotrophic = 45.6% and ultra-oligotrophic = 24.8%), located at low elevation (66.5%, <200 m.a.s.l), close to coastlines (72.5%, 0–50 km), and underlain by sedimentary geology (66.5%).
