Objective(s): The objective of this research is to develop a hydro-ecological model for small Arctic lakes that can be used to assess the sensitivities / vulnerabilities of Arctic lake ecosystems to various forms of disturbance, such as future climate change or water withdrawal. The researchers wish to develop 1) a geochemical hydrologic model for use in melting permafrost conditions, 2) models of aquatic productivity relationships for major nutrients, 3) paleolimnological models of historical changes in water budget / geochemical composition / aquatic productivity for small lakes in the study region. Pairs of lakes, disturbed and undisturbed, will be studied. Disturbance means affected by obvious permafrost slumping. The disturbed lakes will provide data on the potential effects of altered geochemical loading from permafrost degradation, and will act as historical analogues for the future effects of climate change. Current research sites will be on Crown land, pending approval of work on private lands.
