Limnological data from Southampton Island lakes, Nunavut

This thesis aims at providing information on the paleogeography, paleoecology and paleoclimatology of the south-western Foxe Basin region, Southampton Island (Nunavut), through the combined analysis of biological and geochemical indicators preserved in lake sediments. Our specific objectives were to provide data on regional climate variability since the last deglaciation (between 7.7 ka BP and 6 ka BP) and to specify the nature of postglacial landscape evolution in the region. Long and short sediment cores were extracted from lakes in the northeastern part of the island. Paleolimnological analyses of diatoms were performed on the sampled sediments. Core chronologies are based on 210 Pb and 14C dates, and diatom-based quantitative reconstructions of pH, water temperature, air temperature and dissolved organic carbon were generated. This study will help assess impacts of future climatic and environmental changes in this remote part of the Canadian Arctic.
