LPA Home Laboratoire de Paleoecologie Aquatique

The Laboratoire de Paléoécologie Aquatique (LPA - Aquatic Paleoecology Laboratory) is a group of 10 research scientists, post-doctoral fellows and graduate students in the fields of paleolimnology and paleoceanography, in both the departments of geography and biology dedicated to using paleolimnological techniques to provide historical perspectives to environmental changes.

The paleolimnologic research in this laboratory focuses on the use of fossil freshwater algae (diatoms and dinflagellate cysts), insects (chironomid larvae) and microcrustaceans (ostracods) preserved in freshwater and marine sediment archives to reconstruct changes in climate and the environment during the Quaternary period and post-glacial times.

The studies take place in Labrador, northern Québec, Nunavut (Foxe Basin, Canadian mid- to high Arctic), Spitsbergen and Patagonia. The laboratory administers the Circumpolar Diatom Database (CDD) since 1997, containing information from more than 550 lakes until now.

	Welcome to LPA's website		News Congratulations to Valerie Labrecque which has been awarded the prize for best average in 2008-2009 by the Société de géographie de Québec. Congratulations to Reinhard Pienitz who was awarded the DiscoveryAccelerator Supplements (DAS) program (2008-2009) grant
