Past projects

ArcticNet Labrador Fjord Project

During the ArcticNet (Arctic Network) mission in November 2006, sediment cores were collected from 3 fjords of the Labrador coast (Canada). Inuit people in this region depend primarily on the sea and sea ice for their activities, such as hunting and fishing, but also for their traveling. They are concerned by the changes induced in …

Greater Snow Geese Project

Due to protection measures and changes in the overwintering habitat, the population of breeding snow geese (Chen caerulescens atlantica) on Bylot island has increased dramatically over recent years. As a result, the nutrient load originating from faecal goose droppings has increased, which may profoundly change the relative concentrations of C, N and P in the …

Paleolimnological reconstruction of the trophic history of Lake Carheil, Fermont (Quebec, Canada)

Since several of years, major cyanobacterial blooms have been reported at the surface Lake Carheil (Fermont, Quebec) during summer, indicating serious eutrophication issues. The Duplessis watershed organization (OBV Duplessis) has already drawn a global picture of the current situation but only few data are available concerning the past conditions of the lake. However, in order …

Paleolimnological reconstruction of trophic status of lakes Nairne (Charlevoix-Est) and Memphremagog (Estrie) Project

Quebec society is increasingly concerned about the consequences of the eutrophication of the lakes and cyanobacteria blooms. It is now crucial to achieve a deeper understanding of this problem, its origins, and its consequences, but also to increase our knowledge for taking concrete and appropriate action.

A paleolimnological approach will be used for this project. …

PASADO Project

A Special Research Opportunity project, headed by professor Pierre Francus from Centre Eau Terre Environnement (INRS – Québec city), received an important grant from NSERC for a total amount of $ 791 356. This grant supports the research of 10 research teams from 8 Canadian universities in the frame of the PASADO project (Potrok Aike …

Pingualuit Crater Lake Project

Context Earth’s climate is changing rapidly, with the global temperature now rising at a rate unprecedented in modern history. These climate changes are being experienced particularly intensively in the Arctic. Arctic average temperature has risen at almost twice the rate as in the rest of the world in the past few decades (ACIA 2004). Arctic …

Project about the limnological conditions of a thermokarst lake near Umiujaq (Nunavik)

New lakes are usually formed in thermokarst trough caused by permafrost thawing. Weathering phenomena associated with permafrost thawing results in a very turbid environment. Since appearance of those lakes is spreading to the north and their physico-chemical parameters and their consequences on the territory remains poorly known, my essay, among other studies, studies one of …

Project of reconstruction of trophic status of lake Nairne, Charlevoix, Quebec

Residents and municipalities surrounding many southern Quebec lakes have expressed concerns since the early 2000s following massive cyanobacterial blooms that were followed by rapid deterioration of the lake’s water quality. As a consequence, severalresearch programs have been initiated in order to provide those municipalities with an array of tools for a better management of these …
