Participate in and contribute information to AMAP expert work groups for trend monitoring for POPs and mercury. v. Integrate our mercury trend assessments with studies we are conducting in the western provinces as part of Canada’s Clear Air Regularly Agenda for its Mercury Science Assessment. vi. Work with communities in capacity building and training.

To provide for the collection, interpretation, and dissemination of surface water quantity data and information and services that are vital to meet a wide range of water management, engineering and environmental needs across Canada. Main gaps: The current hydrometric network is deficient in terms of understanding the regional hydrology and river regimes across Canada. The map below integrates Environment Canada’s two key frameworks: the National Drainage Area Framework with the National Terrestrial Ecological Framework to identify network deficiencies. In order to have sufficient information there needs to be at least one active hydrometric station measuring natural flow in each corresponding ecodistrict within a sub-sub drainage area. This strategy ensures that there will be sufficient information to understand the hydrological processes and the interrelationships with the landscape. This information is essential for research and enhancing our predictive capabilities and data transfer. As the map shows, areas of sufficiency are concentrated in the southern, more populated regions of the country. Network sufficiency declines to the north and northeast, with great extents of northern Canada having no coverage at all. Network type: in-situ.water level and streamflow monitoring stations

The main objective of the Arctic Avian Monitoring Network is to characterize the occurrence of birds in the Arctic to support regulatory responsibilities and conservation of birds and the biodiversity on which they depend. Temporal and spatial changes can be used to indicate changes in ecosystems that might otherwise be difficult to detect (e.g. marine areas) and can also be used to model predicted changes due to human activity. Main gaps: Large gaps both spatially and temporally. Many datasets cover short periods. Some species groups not well covered (e.g. landbirds and shorebirds) Network type: Network consists of programs divided into three species themes that combine common aspects of biology and human use: Waterfowl: e.g. ducks geese and swans • centered on aerial surveys of high density breeding areas and following non-breeding birds using satellite telemetry Seabirds: e.g. gulls, terns and auks • centered on surveys at breeding colonies and of birds at sea (either by direct observation or through the use of data loggers) Shorebirds: e.g. sandpipers, plovers and phalaropes • focused on broad-scale, stratified sampling of terrestrial areas and aerial surveys of non-marine habitats

ArcticNet brings together scientists and managers in the natural, human health and social sciences with their partners in Inuit organizations, northern communities, government and industry to help Canadians face the impacts and opportunities of climate change and globalization in the Arctic. Over 110 ArcticNet researchers and 400 graduate students, postdoctoral fellows, research associates and technicians from 28 Canadian universities and 8 federal departments collaborate on 28 research projects with over 150 partner organizations from 15 countries. The major objectives of the Network are: • Build synergy among existing Centres of Excellence in the natural, human health and social Arctic sciences. • Involve northerners, government and industry in the steering of the Network and scientific process through bilateral exchange of knowledge, training and technology. • Increase and update the observational basis needed to address the ecosystem-level questions raised by climate change and globalization in the Arctic. • Provide academic researchers and their national and international collaborators with stable access to the coastal Canadian Arctic. • Consolidate national and international collaborations in the study of the Canadian Arctic. • Contribute to the training of the next generation of experts, from north and south, needed to study, model and ensure the stewardship of the changing Canadian Arctic. • Translate our growing understanding of the changing Arctic into regional impact assessments, national policies and adaptation strategies. Main gaps: [Not specified] Network type: Thematical observations:Yes Field stations: Yes on Land (see CEN sheet) and Marine (CCGS Amundsen) Community based observations: Yes Coordination: Yes

The Centre for Northern Studies (www.cen.ulaval.ca; CEN: Centre d’études nordiques) is an interuniversity centre of excellence for research involving Université Laval, Université du Québec à Rimouski and the Centre Eau, Terre et Environnement de l'Institut national de la recherche scientifique (INRS). Members also come from the following affiliations: Université de Montréal, Université du Québec à Chicoutimi, à Montréal and à Trois-Rivières, Université de Sherbrooke, and the College François-Xavier Garneau. The CEN is multidisciplinary, bringing together over forty researchers including biologists, geographers, geologists, engineers, archaeologists, and landscape management specialists. The CEN community also counts two hundred graduate students, postdoctoral fellows, and employees. CEN’s mission is to contribute to the sustainable development of northern regions by way of an improved understanding of environmental change. CEN researchers analyze the evolution of northern environments in the context of climate warming and accelerated socio-economic change and train highly qualified personnel in the analysis and management of cold region ecosystems and geosystems. In partnership with government, industry and northern communities, CEN plays a pivotal role in environmental stewardship and development of the circumpolar North. CEN research activities are focused on three themes: 1 -Structure and function of northern continental environments. 2 -Evolution of northern environments in the context of global change. 3-Evaluation of the risks associated with environmental change and development of adaptation strategies. In 2009, CEN organised an international workshop with the European SAON network SCANNET and also partners throughout Canada. The workshop culminated in the formal incorporation of CEN stations within SCANNET (http://www.scannet.nu/). Main gaps: [Not specified] Network type: CEN operates the CEN Network, an extensive network of meteorological and field stations that were established in consultation with northern communities. The CEN Network comprises over 75 climate and soil monitoring stations and eight field stations distributed across a 4000 km North-South gradient from boreal forest to the High Arctic. The eight field stations are situated at the following sites: Radisson, Whapmagoostui- Kuujjuarapik, Umiujaq, Lac à l’Eau Claire (in the proposed new park Tursujuq), Boniface River, Salluit, and Bylot and Ward Hunt Islands, which are part of two National Parks in Nunavut. The main field station at the heart of the CEN Network is at Whapmagoostui-Kuujjuarapik.

• collect field based measurements of permafrost thermal state and active layer thickness (Essential Climate Variables identified by WMO/GCOS) • disseminate information on permafrost thermal state and active layer thickness (increase public availability • document current permafrost conditions and changes in these conditions and conduct analysis to explain these changes • provide essential information on permafrost conditions for decision making in Canada’s north to ensure sustainable development and to develop strategies to adapt to climate change Main gaps: Large regional gaps still exists especially in central region between Mackenzie Valley and Hudson Bay There is also a lack of long-term funding to maintain network operation and ensure ongoing data collection. Network type: Thematic observations (permafrost thermal state and active layer thickness), consisting of several field sites (>150) throughout northern Canada (see recent GCOS ECV report for map). Most sites in remote areas Limited community based monitoring

The State and Evolution of Canada's Glaciers initiative provides information and data products produced by the Federal Government's National Glacier-Climate Observing System (monitoring, assessment and data portal) and related freshwater vulnerability research in western and northern Canada. The Glacier-Climate Observing System is delivered through an integrated monitoring and research collaborative comprised of Natural Resources Canada-Geological Survey of Canada (lead agency), Geomatics Canada-Canada Centre for Remote Sensing, Environment Canada-National Water Research Institute and Water Survey of Canada, Parks Canada Agency, C-CORE Polar View, and academic partners that include the universities of British Columbia, Northern British Columbia, Alberta, Calgary, Lethbridge, Saskatchewan, Regina, Toronto, Brock, Trent and Ottawa, and related academic initiatives such as the Cold Water Collaborative and those supported by the Canadian Foundation for Climate and Atmospheric Science. SECG is a contribution to the NRCan Earth Sciences Sector - Climate Change Geoscience Program. With this data research is conducted on the relationship between climate, glacier fluctuations and their impacts on freshwater systems (e.g., river flow, cold stream ecology, groundwater recharge, flow to oceans). The development of improved remote sensing tools is also a major research thrust. With the support of the Canadian Space Agency, European Space Agency, the Canadian Consortium for Lidar Environmental Applications Research (C-CLEAR), and the NASA - Wallops Flight Facility, new tools and a systematic approach are increasingly brought to bear to understand more completely and with reduced uncertainty the magnitude, causality and impacts of Canada's changing glaciers. System outputs are used to a) inform national and international climate change programs and process; b) improve knowledge regarding the nature and locations of historical, current, and potential future impacts of climate change, c) assist Canadians in understanding and adapting to climate change impacts on natural resources at a regional and national scale. The System also provides leadership and co-ordination of Canada's contribution to World Meteorological Organization’s Global Terrestrial Observing System (GTOS) and its Global Terrestrial Network for Glaciers (GTN-G), the contribution of Essential Climate Variables for GEO/GEOSS, and providing such as Official Communications to the Parties of the Convention UNFCCC. Main gaps: Regional representativeness has been improving with the re-establishment of former sites or the establishment of new sites. Contributions to thematic needs such as water resources, flow to oceans and sea-level change will require improved co-ordination with hydrometric and other monitoring entities. Which Network type: - Thematical observations: yes - Field stations: yes, 20 reference observing sites - Community based observations: some in development (Grise Fjord) - Coordination: SECG guides and co-ordinates observations conducted by partners; SECG co-ordinates reporting for Canada (e.g., GCOS-GTN-G, WGMS)

The main objective is to monitor and assess the impacts of global change on the Human-Rangifer System across the Arctic through cooperation, both geographically and across disciplines. CARMA is a network of researchers, managers and community people that share information on the status of the world's wild Rangifer (reindeer and caribou) populations and how they are affected by global changes (e.g. climate change and industrial development). CARMA is primarily focussed on the status of most of the large migratory Rangifer herds and thus, as yet, do not deal with woodland caribou and Peary caribou in North America or forest and marine reindeer in Fennoscandia and Russia. As well, the do not deal with domestic reindeer or the herding economy. Network type: - Networking - Data, experience and knowledge exchange

The Collaborative Interdisciplinary Cryospheric Experiment (C-ICE) is a multi-year field experiment that incorporates many individual projects, each with autonomous goals and objectives. The science conducted has directly evolved from research relating to one of four general themes: i. sea ice energy balance; ii. numerical modeling of atmospheric processes; iii. remote sensing of snow covered sea ice; and iv. ecosystem studies.

Short Term i) to provide additional information for use in updating health advisories. Long Term i)to investigate the fate and effects of contaminant deposition and transport to the Yukon, allowing Northerners to better manage the issue of contaminants. ii)to determine levels of contaminants for use in long term trend monitoring.
