A Limnological Investigation of a Large Arctic Lake, Nettilling Lake, Baffin Island

Abstract

Reports the physical and chemical data obtained from a 1956 survey of this lake in south-central Baffin. Its geographical location, morphometry, ice, temperature, and transparency are outlined, also its oxygen and mineral content. Fish, bottom fauna, and plankton crustaceans collected are listed, including some new to the Nearctic and some northernmost records. Thermal conditions in arctic lakes are discussed, as are differences between the two morphological regions of Nettilling, and restricted distributions of some of its organisms.
