Objectif(s): The central aim of the ArcticNet marine-based research program is to study on a long-term basis how climate induced changes are impacting the marine ecosystem, contaminant transport, biogeochemical fluxes, and exchange processes across the ocean-sea ice-atmosphere interface in the Canadian Arctic Ocean.

Description du projet: The central aim of the ArcticNet marine-based research program is to study on a long-term basis how climate induced changes are impacting the marine ecosystem, contaminant transport, biogeochemical fluxes, and exchange processes across the ocean-sea ice-atmosphere interface in the Canadian Arctic Ocean. Ultimately, the knowledge generated from this multi-year program will be integrated into regional impact assessments to help decision makers develop effective adaptation strategies for the changing coastal Canadian Arctic. The proposed ArcticNet 2009 marine-based research program will be conducted in partnership with Imperial Oil Resources Ventures Limited (IORVL), the France-led Malina project and the Geotraces project funded by the Canadian International Polar Year program. These partnership initiatives are aimed at increasing the diversity, temporal and spatial coverage of environmental data collected by the ArcticNet network. 1) Meteorology, ocean & sea ice component: the general objective of this research component is to collect data on the ocean-sea ice-atmosphere (OSA) interface over a range of time and space scales, focusing on spatial and temporal variability over diurnal, seasonal and inter-annual time scales. 2) Marine resources and environment component: in the Arctic Ocean, sea-ice dynamics and hydrography will ultimately determine primary production, microbial activity, zooplankton and larval fish dynamics and benthos productivity. The objectives of this research component are 1) to quantify and map the summer-fall distribution and contamination of the main components of the pelagic and benthic food webs in the study area and 2) to quantify the response of the pelagic and benthic communities to physical forcing processes over the summer-fall season. 3) Geology/bathymetry component: the major goal of this research component is to conduct a bathymetric and sediment characterization survey to investigate seafloor stability conditions at the outer shelf/upper slope area of the central Beaufort Sea and to provide the necessary geosciences knowledge to understand the distribution of ecologically and biologically sensitive benthic ecosystems. Three of the five general objectives of ArcticNet are to: 1) involve northern communities and Inuit organizations as partners through bilateral exchange of knowledge, training and technology; 2) contribute to the training of the next generation of young Arctic specialists (including northern residents) and, 3) contribute to the development and dissemination of the knowledge needed to formulate policies and strategies to adapt to change in the Arctic. Hence, it is ArcticNet’s mandate to involve the residents of the Inuvialuit Settlement Region (ISR) at various levels of research and training. Oceanographic fieldwork in the ISR started in 2004 which generated various involvement opportunities for the residents and more opportunities are expected to arise throughout the duration of ArcticNet. As part of ArcticNet’s education and training initiatives, the Schools on Board program was developed to bridge Arctic research with science education in high schools across Canada. Since 2005, the ArcticNet Schools on Board program has welcomed a number of Inuit students from the NWT and Nunavut onboard the CCGS Amundsen. This is an excellent opportunity for young, enthusiastic students to see part of their environment and experience firsthand Arctic research. A compendium of ArcticNet research results (2004-2008) will be submitted to the aforementioned organizations. ArcticNet’s annual report and quarterly newsletter are also sent out to Inuit partners and Northern organizations. All results ensuing from ArcticNet’s marine-based research program are made available as peer-reviewed primary publication in scientific journals. The fieldwork for this study will be conducted from July 11 to October 18, 2010, in the Beaufort Sea/Mackenzie Shelf/Amundsen Gulf region, from the icebreaker CCGS Amundsen.
