Abstract

Most of the world’s lakes are in the Arctic, yet very little is known about these aquatic environments. We present here the size and depth data for five large lakes in the Greiner lake watershed near Cambridge Bay, southern Victoria Island, Nunavut. Using satellite imagery, a watershed digital surface model (WDSM) was generated to estimate surface area of Greiner lake, First lake, Second lake, Inuhuktok and Nakyulik. Bathymetry for each lake was generated using depth measures that were taken as point measures and a Biosonics or Humminbird echo sounder.
