The Northern Contaminants Program aims to reduce and where possible eliminate long-range contaminants from the Arctic Environment while providing Northerners with the information they need to make informed dietary choices, particularly concerning traditional/country food. To achieve these objectives the NCP conducts research and monitoring related to contaminants in the Arctic environment and people. Monitoring efforts focus on regular (annual) assessment of contaminant levels in a range of media, including air, biota and humans. Environmental research is conducted into the pathways, processes and effects of contaminants on Arctic ecosystems while human health research focuses on assessing contaminant exposure, toxicity research, epidemiological (cohort) studies, and risk-benefit assessment and communications. Main gaps: Contaminant measurements in Arctic seawater, toxicity data specific to Arctic species. Network type: - Thematical observations: Contaminants levels and relevant ancilliary parameters - Field stations: Atmospheric observing stations at Alert, Nunavut and Little Fox Lake, Yukon. - Community based observations: Numerous communities throughout the Canadian Arctic participate in sample collection - Coordination: National coordination of the program provided by the NCP secretariat, which also acts as liaison with AMAP.

In order to assess the spatial and temporal patterns of the a-, b- and g-isomers of hexachlorocyclohexane (HCH) in the arctic biotic and abiotic environment, it is proposed that: (1) concentrations and ratios of HCH isomers be compared over time in air, water, seals, beluga, polar bears and seabirds to determine any shifts in isomeric ratios and how those shifts interrelate among the various media, and (2) concentrations and ratios of HCH isomers be compared spatially in the abiotic and biotic media and reasons for any patterns explored.
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 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.
Observations of the Arctic Ocean have been made since the 1800s at varying levels of intensity. The objective is to gain a better understanding of the physical and chemical composition of Arctic waters, the circulation of the waters within the Arctic Ocean, and flows into and out of the Arctic Ocean. Physical observations are conducted on properties of the water column including ocean temperature, sea surface temperature, salinity, pH, carbon, changes in ice coverage and extent, hydrographic measurements, nutrients, etc. Surface drifters either embedded in the ice, or (lately) able to float and operate in ice infested waters, provide measurements of a limited number of surface ocean and meteorological variables. . Additional observations are obtained on ocean currents, waves and tides. Biological observations are captured within a separate inventory item titled “Arctic Marine Biodiversity Monitoring”. Recently, a focus has been on increasing understanding of the impacts of climate change on Arctic waters (e.g., increasing temperature, decreasing pH, decreasing salinity, changing ice conditions, etc.). Data is gathered by ship with in situ measurements, deployment of moorings and buoys, helicopters (e.g. for ice measurements), and satellites (e.g. sea surface temperature). Main gaps: Large geographic areas of the Arctic are not covered regularly. Network type: - Thematical observations: of all oceanographic parameters - Field stations: Research ships and ice breakers of the Canadian Coast Guard; other ships of opportunity as available; moorings and buoys - Community based observations: - Coordination: National coordination of the program provided within Fisheries and Oceans Canada, and the National Centre for Arctic Aquatic Research Excellence (NCAARE)
To acquire atmospheric data in support of both the prediction and detection of severe weather and of climate trend and variability research. This serves a broad range of users including researchers, policy makers, and service providers. Main gaps: Long-term, atmospheric monitoring in the North poses a significant challenge both operationally (e.g. in-situ automated snowfall measurements) and financially (charterd flights for maintenance and calibration).Most monitoring in the North is limited to populated areas. Attempts to develop an AMDAR capacity out of First Air and Canadian North fleets failed due to economical and technical difficulties. As demonstrated through impact studies, benefits of AMDAR in the North would be tremendous, however would require acquisition and deployment of specialized sensing packages such as TAMDAR (which includes measurements of relative humidity), development of datalink capacity through satellite communications (e.g. Iridium), and upgrading some aircraft systems when possible, especially the aircraft navigation systems. Network type: Atmospheric observing stations over land and sea composed of: - Surface Weather and Climate Network: o In-situ land stations comprising both Hourly stations and Daily Climate observations - Marine Networks: o Buoys (moored and drifting) o Ships: Automatic Volunteer Observing System - Upper Air Network: o In situ (radiosonde) o In situ Commercial Aircraft (AMDAR)
The project aims at establishing a long-term Arctic-Antarctic network of monitoring stations for atmospheric monitoring of anthropogenic pollution. Based upon the long and excellent experiences with different scientific groups performing air monitoring within the Arctic Monitoring and Assessment Programme (AMAP), an expanded network will be established including all AMAP stations and all major Antarctic “year-around” research stations. As an integrated project within the “International Polar Year 2007-08” initiative, the ATMOPOL co-operation intend to • Establish a long-term coordinated international Arctic-Antarctic contaminant programme. • Develop and implement a joint sampling and monitoring strategy as an official guideline for all participating stations. • Support bi-polar international atmospheric research with high-quality data on atmospheric long-range transport of contaminants (sources, pathways and fate). • Support future risk assessment of contaminants for Polar Regions based on effects of relevant contamination levels and polar organisms Based upon the well-established experiences of circum-Arctic atmospheric contaminant monitoring in the Arctic under the AMAP umbrella, a bi-polar atmospheric contaminant network will be established and maintained. In conjunction with the polar network of atmospheric monitoring stations for air pollution, surface-based and satellite instrumentation will be utilised to provide the characterization of the Arctic atmospheric-water-ice cycle. Together with numerical weather prediction and chemical transport model calculations, simultaneous measurements of pollutants at various locations in the Arctic and Antarctic will enhance our understanding of chemical transport and distribution as well as their long-term atmospheric trends. In addition to investigating the importance of atmospheric transport of pollutants an understanding of the transference and impact of these pollutants on both terrestrial and marine environments will be sought. A secretariat and a “scientific project board” will be established. During this initial phase of the project (2006), a guideline on priority target compounds, sampling strategies, equipment and instrumentation, analytical requirements, as well as quality assurance protocols (including laboratory intercalibration exercises) will be developed and implemented. The ATMOPOL initiative aims to address highly relevant environmental change processes and, thus, will strive to answering the following scientific questions: • How does climate change influence the atmospheric long-range transport of pollutants? • Are environmental scientists able to fill the gaps in international pollution inventories and identification of possible sources for atmospheric pollution in Polar Regions? • What are the differences in transport pathways and distribution patterns of various atmospheric pollutants between Arctic and Antarctic environments? Why are there such differences? What is the final fate of atmospherically transported pollutants and how does this impact on the environment and indigenous people?In order to understand the underlying atmospheric chemistry of pollution, e.g. atmospheric mercury deposition events, routine surface measurements of UV radiation as well as campaign related measurements of UV radiation profiles will also be included.The project will establish a cooperative network on atmospheric contaminant monitoring in Polar Regions far beyond the IPY 2007/08 period and is, thus, planned as an “open-end” programme. All produced data will be available for all participating institutions for scientific purposes as basis for joint publications and reports from the ATMOPOL database to be developed.
The project will provide a long-term, pseudo-global validation support to the ENVISAT-1 atmospheric measurements, based on mutually consistent high-quality solar and lunar observations from FTIR spectrometers operated at primary and a number of complementary NDSC stations. The validation is limited to a number of target species, most of which are primary NRT or OL level-2 products of the mission, with focus on NOy components: O3, NO2, NO, N2O, HNO3, HNO4, H2CO, CO and CH4. Synergistic use will be made of column and profile data from MIPAS, GOMOS and SCIAMACHY. The ground network will deliver mean vertical column abundances for all target species with NDSC-type quality, and height profile information for some target gases as secondary products to the PI's home institute, where the correlative analyses with the ENVISAT-1 products will be done. Asynoptic mapping tools will support the validation efforts.
The objectives of the project are: A) to determine temporal trends in atmospheric mercury concentrations and deposition processes of mercury in the Arctic, and to assist in the development of long-term strategies for this priority pollutant by: i) measuring ambient air Total Gaseous Mercury (TGM) concentrations in the Canadian Arctic (Alert) and investigating the linkage to elevated levels of mercury known to be present in the Arctic food chain; ii) investigating and establishing the causes of temporal variability (seasonal, annual) in mercury concentrations so that realistic representations (models) of atmospheric pathways and processes can be formulated, tested and validated; iii) studying the chemical and physical aspects of atmospheric mercury vapour transformation (oxidation) after polar sunrise and the resultant enhanced mercury deposition to the sea, snow and ice surfaces each year during springtime; and iv) obtaining a long-term time series of atmospheric mercury (TGM) concentrations at Alert for the purpose of establishing whether mercury in the troposphere of the northern hemisphere is (still) increasing and if so, at what rate; B) to establish a sound scientific basis for addressing existing gaps of knowledge of the behaviour of mercury in the Arctic environment that will enable international regulatory actions to reflect the appropriate environmental protection strategies and pollution controls for the Arctic by: i) studying the relative roles of anthropogenic and natural sources of mercury so as to clarify understanding of the atmospheric pathways leading to the availability of mercury to Arctic biota; ii) studying tropospheric TGM depletion mechanisms/processes leading to enhanced input of mercury to the Arctic biosphere in spring; iii) undertaking essential speciated measurements of particulate-phase and/or reactive gaseous-phase mercury as well as mercury in precipitation (snow/rain) to quantify wet and dry deposition fluxes into the Arctic environment; and vi) providing the scientific basis for the information and advice used in the preparation and development of Canadian international strategies and negotiating positions for appropriate international control objectives.
The objectives of this project are: A) to determine the pathway for the transfer of mercury in snowmelt to sea water during the melt period at Alert; B) to determine the extent of open water and wet ice in the summer Arctic as it affects the surface exchange of Hg using satellite radar imagery; and C) to determine the atmospheric dynamics associated with the photochemistry of mercury episodically during the polar sunrise period.
The objectives of this project are A) to determine coplanar polychlorinated biphenyls (PCBs), polychlorinated naphthalenes (PCNs), brominated diphenyl ethers (BDPEs), chlorophenolic compounds and chloroparaffins in air from arctic monitoring stations; and B) to search for other "new" chemicals in the arctic environment, not currently monitored by Canada's Northern Contaminants Program (NCP) but of potential concern based on known persistence, extent of usage and toxicology.
