| Résumé | (Sommaire disponible en anglais seulement)
The rapid Arctic sea-ice decline impacts coastal ecosystems and the services they support (e.g., land-fast sea ice platform for hunting, fishing and
travelling, provisioning services), with direct consequences for local communities. The potential implications of climate warming for sea-ice ecosystems, including their biological wealth, are not straightforward and strongly depend on local
geographic settings, as well as pressures posed by human activities. Therefore, to generate more locally-relevant projections of their future evolution in relation to global climate changes, a detailed understanding of their present and historical
(long-term) sensitivity and response to environmental drivers is required.
In September 2021, a sampling campaign onboard the research vessel William-Kennedy took place in the Nain area as part of the Marine Work Package of the Nunatsiavut Coastal
Interactions Project (NCIP) and the Marine Geoscience for Marine Spatial program of NRCan. During the 7-day cruise in the area, a total of 205 successful operations were conducted by the 12 scientists on board: 17 ocean drifters were released,
water-column profiling was conducted at 43 locations, multibeam mapping data was collected, and a suite of environmental samples (14 water samples, 29 phytoplankton nets, 14 zooplankton nets, and 72 surface sediment and core samples) was collected.
This material will be used to investigate present-day and past changes in oceanographic conditions and primary production (i.e., the basis of the marine food web), the presence of nanopollutants (inorganic nanoparticles and nanoplastics), develop
nautical charts and monitor geological hazards in the Nain region. This project will provide insights for facing the challenges and opportunities related to contemporary and future climate changes and their impacts on the resilience and management of
the coastal ecosystem, and access to traditional subsistence resources.
Co-led by the University of New Brunswick (UNB) and Natural Resources Canada (NRCan), this cruise was a collaboration between the Government of Nunatsiavut, Fisheries and
Oceans Canada - Maritime region (Canadian Hydrographic Service), Dalhousie University, Université Laval, Université du Québec à Montréal, and Memorial University, and was funded by the Natural Sciences and Engineering Research Council of Canada
(NSERC) and NRCan. |
