Inuit have reported greater inter-annual variability in seasonal sea ice conditions. For Deception Bay (Nunavik), an area 15 prized for seal and caribou hunting, an increase in solid precipitation and a shorter snow cover period is expected in the near future. In this context, and considering ice-breaking transport in the fjord by mining companies, we monitored sea ice in the area for three seasons of ice between 2015 and 2018. This article presents a case study for the combined use of TerraSAR-X and time-lapse photography time-series in order to monitor snow-covered sea ice seasonal processes. The X-band median backscattering is shown to reproduce the seasonal evolution expected from C-band data. Two different freeze-up and breakup processes are characterized.

  • Review of 2014-2015 Activities Pierre-Michel Fontaine (1966-2015)
    REVIEW OF 2014-2015 ACTIVITIES PIERRE-MICHEL FONTAINE (1966-2015) It is with regret and sadness that the Kativik Environmental Quality Commission lost one of its members, Pierre-Michel Fontaine, on September 2, 2015. The Commission acknowledges the significant contribution of Pierre- Michel to its work. Since his nomination in June 2008, he brought a unique perspective to the discussions resulting from his professional and scientific expertise. Pierre-Michel was a very friendly individual, imbued with great kind- ness. He was above all a friend and leaves an important void behind him. 2 THE COMMISSION Created in 1979 following the signing of the James Bay and Northern Quebec Agreement (JBNQA), the Kativik Environmental Quality Commission is respon- sible for evaluating and examining the environmental and social impacts of projects of provincial nature in Nunavik, the Québec region located north of the 55th parallel. The Commission is composed of 8 members and the chairman. The Government of Quebec and the Ka- tivik Regional Government (KRG) appoint 4 members each. The Government of Quebec appoints the chair- man, with the approval of KRG. Avataani installations visit in Kujjuuaq - August 2014 3 REVIEW OF 2014-2015 ACTIVITIES The Commission is pleased to present this report on its activities for the period April 1, 2014 to March 31, 2015. Among the year’s achievements were some innovative projects for waste management in Nun- avik, including new northern landfills in Kangirsuk and Inukjuaq and a third project involving the collection and storage of residual hazardous materials in Kuu- jjuaq. In addition, Raglan mine now has an operating wind turbine, a pilot effort in a wind farm project that would involve a total of six turbines.

This responsible management of the public purse must also extend to infrastructure investments. Québec has important choices to make. Although investments are urgently needed to maintain the safety and quality of our aging buildings, schools and roads, we must not lose sight of the need for new infrastructures. These investments must be made responsibly, keeping in mind our citizens’ ability to pay. Québec’s recent history in infrastructure investments can be broken down into two phases. The first was a period of chronic under-investment that began in the 1990s and continued until the early 2000s. The second was the inevitable “catch-up” phase, which began in earnest in 2006-2007. It is now time to embark on a stable path that will allow us to respond to the undeniable priority of maintaining the quality and safety of our existing infrastructures while responsibly developing Québec’s public infrastructure network.

  • Chapter 6. Permafrost and Climate Change in Nunavik and Nunatsiavut: Importance for Municipal and Transportation Infrastructures
    Chapter 6. Permafrost and climate change in Nunavik and Nunatsiavut: Importance for municipal and transportation infrastructures Lead authors Michel Allard, Mickaël Lemay, Carl Barrette, Emmanuel L’Hérault, Denis Sarrazin Centre d’études nordiques (CEN), ArcticNet, Université Laval, Québec, QC Contributing authors T. Bell, and G. Doré Abstract Permafrost degradation is seriously affecting the natural environment. The landscape is changing through thermokarst that takes place mostly in the discontinuous permafrost zone and through thicker active layer depth and more frequent slope processes in the continuous zone. Northern residents are affected as vegeta- tion, water bodies and soil drainage are greatly modified, which has an impact on resources traditionally available for humans. The modern built environment is also affected. Transportation infrastructure is being studied and adaptive solutions are sought, applied and tested. To protect and optimize the major invest- ments required for extensive housing and construction, the urban planning of communities calls upon better permafrost maps and prediction of permafrost behavior. Final permafrost degradation around 0°C appears to be primarily under the influence of unfrozen water content and heat brought to the thawing interface by groundwater. This process is also effective in accelerating localized thawing under man-made infrastructures. Collection and organization of permafrost information in geographic information systems (GIS) allows for the integration of essential knowledge and provides a very useful tool for establishing situation diagnostics, sharing information with stakeholders and communities, and supporting multidisci- plinary decision making for land use planning. The principal adaptive measures lie in adapting foundation types to mapped permafrost conditions to ensure a prolonged service life of buildings.

ABSTRACT In Nunavik, permafrost degradation is now inevitable and it will eventually become problematic for the integrity of some transportation infrastructures owned by Ministère des Transports du Québec (MTQ). This study was initiated by the MTQ in order to adapt its transportation infrastructures to the new climatic reality. The purpose of this study is to identify the consequence of global warming on infrastructures, to review all mitigation techniques that can be used to counter permafrost degradation under transportation infrastructures and to carry out a performance assessment of the Nunavik runways and access roads since their construction in order to determine the appropriate adaptation techniques to reduce permafrost degradation. The assessment made it possible to identify six unstable runways and two unstable access roads.
