Study of the Behaviour of Sea and Freshwater Ice in the Vicinity of Nunavik Maritime Infrastructure - Contribution of Local Knowledge and Remote Sensing

Workshops and consultations were held in local communities (Kuujjuaq, Umiujaq and Quaqtaq) to gather traditional knowledge and community observations about ice, climate change and use of the marine infrastructures. A joint validation meeting was also organized between representatives (elders, teachers and high school students) of the three communities. A specific report is available at Kativik Regional Administration (KRG). Hourly photos were acquired from surveillance type cameras at the marine infrastructures. Ancillary weather data were added. A selection of photos are available on the KRG website. All photos were analysed to detect the presence, type and movement of ice, as well as water levels, wind and waves. To determine the spatial and temporal characteristics of coastal and river ice, ice maps were produced every 3-4 days during freeze-up and break-up in the vicinity of the marine infrastructures, using high resolution RADARSAT-2 images and processing procedures developed or adapted at INRS. All of the information gathered was compiled to create a historical profile and description of the present conditions of ice and extreme events in order to feed models that will predict transformations and impacts of ice on Nunavik maritime infrastructure under climate change.
