Introduction: ..., the 2012-2015 Business Plan of the Government of Nunavut is the formal statement of the Government's goals for the next three years. It includes the plans of ten departments, five territorial corporations, and the Office of the Legislative Assembly. The Business Plan is a strategic and operational plan tied to the Main Estimates, which provides details of expenditures projected to be incurred. The Business Plan is introduced by the Tamapta: Building our future together - [Government of Nunavut Priorities]. This is followed by an Environmental Scan, an Inuit Employment Plan, and Core Business sections, which detail program areas and tactical/operational priorities for the next three years. This year's Business Plan is contained in two Volumes. Volume I includes plans for the Office of the Legislative Assembly and the ten departments of the Government of Nunavut. Volume II includes the corporate plans for the five territorial corporations. The Environmental Scan provides the context, or setting, for the operations of each department and territorial corporation. Their clients, challenges (constraints and pressures) and opportunities are described. The Inuit Employment Plan provides information on government-wide Inuit employment goals and initiatives for the 2012-13 fiscal year. It also includes an aggregation of initiatives of individual departments. The Core Business section describes, for all departments and crown corporations, their business lines and the corresponding budgets contained in the Government of Nunavut's 2012-2013 Main Estimates. For each line of business, a status report is provided on priorities identified for the 2011-2012 fiscal year. New priorities for each program are outlined for 2012-2015. The Appendix for each department provides a financial summary of its operations. This information ties the Business Plan to the Main Estimates. Some departments and crown corporations have further appendices with information relevant to their operations. ... (Au)

Paleoeskimo populations on western Victoria Island reached maximum levels in Early Pre-Dorset time and declined abruptly shortly after 3800 14C years BP. The largest subsequent recovery occurred during Dorset time, particularly during Late Dorset, about 1500 to 600 BP. Early Pre-Dorset settlement patterns were similar to those documented for the same period and culture elsewhere in Arctic Canada, with dispersed nuclear families and small extended families occupying the region for most of the year, but with annual aggregations producing sites with 15 or more dwellings. After 3800 BP, large Pre-Dorset aggregation sites are absent. Dorset settlement patterns are dominated by multi-family longhouse - hearth row aggregation sites and by sites with two to four dwellings. Possibly the Dorset were living mainly in snow dwellings on the sea ice during cold seasons, with longhouses and hearth-row sets representing coming-ashore aggregations. Architectural aspects of longhouses and hearth rows indicate a common purpose behind their construction and use throughout the region and apparently throughout Arctic Canada, but their place and time of origin remain obscure. Radiocarbon dates place most longhouses and hearth rows on western Victoria Island in Late Dorset time, as elsewhere, but some dates indicate that these structures were being used in the western Canadian Arctic by Middle Dorset time. The latest Dorset radiocarbon dates from the region overlap with the earliest of the more reliable dates on Thule houses. (Au)

The decline and extermination of an arctic wolf population in East Greenland between 1899 and 1939 were investigated through analysis of 40 years of archival data, which contained records of 252 sightings of wolves or their tracks. Prior to the start of exploitation by Europeans, this small, isolated wolf population probably consisted of about 38 wolves during an average year. Of 112 wolves sighted in early winter, 31.3% were lone wolves, 23.2% were in pairs, and the rest were in larger groups. Mean pack size was 3.3 wolves, and packs of more than four wolves were rare. The population was concentrated in the central part of its range, making it vulnerable to exploitation by Danish and Norwegian commercial hunters, who exterminated the population. Poison was the primary agent of destruction. There was no evidence that other proposed causes of the decline were influential. This study provided the first evidence of an arctic wolf population that was eradicated and highlights the vulnerability of small, isolated wolf populations to excessive harvest. Wolves in the High Arctic may be particularly vulnerable because of their exceptionally low densities, smaller pack sizes, lower pup production, infrequent reproduction, and insular or disjunct distributions.

Our knowledge of the distribution of Arctic birds and how their ranges may be responding to environmental changes in the Canadian Arctic is limited. We gathered five years of species observation data from three sites in the Hell Gate - Cardigan Strait Polynya (Cape Vera, St. Helena Island, and Devil Island) to create an inventory of avian species observed in the polynya, and we compared it to previous observations made at our sites and other sites throughout the Arctic. We examined species diversity measurements over time to suggest possible effects of the polynya on the timing of spring arrival of breeding and migrant species. Of the 39 species observed during our study, 12 were local breeders. Our records provide the northernmost observations for eight species. Species diversity index values at St. Helena Island peaked quickly in mid-June and stabilized by late June, reflecting the arrival and dispersal of migrating species relatively early in the season. These data highlight the importance of the open-water feeding habitat of the polynya not only for breeding birds, but also for migrants. (Au)

We used Canadian Ice Service (CIS) digital charts from 1983 to 2009 to create a climatology of landfast sea ice in the Canadian Arctic. The climatology characterized the spatial distribution and variability of landfast ice through an average annual cycle and identified the mean onset date, breakup date, and duration of landfast ice. Trends in date and duration of onset and breakup were calculated over the 26-year period on the basis of CIS regions and sub-regions. In several sub-regions - particularly in the Canadian Arctic Archipelago - we calculated significant trends towards later landfast ice onset or earlier breakup, or both. These later onset and earlier breakup dates translated into significant decreases in landfast ice duration for many areas of the Canadian Arctic. For communities located in the most affected areas, including Tuktoyaktuk, Kugluktuk, Cambridge Bay, Gjoa Haven, Arctic Bay, and Pond Inlet, this shorter landfast ice season is of significant social, cultural, and economic importance. Landfast sea-ice duration in the interior of the Northwest Passage has not undergone any statistically significant decrease over the time series. (Au)

Ice edges and polynyas have long been noted for their high biological productivity within the Arctic environment. In June 2008, an aggregation of belugas and bowheads was identified at the Franklin Bay ice edge in the eastern Beaufort Sea, adjacent to the Cape Bathurst polynya. We conducted five ice-edge surveys by helicopter to study the distribution and behaviour of the whales. Bowheads were sighted in significantly shallower water than belugas. In addition, we used the helicopter platform to observe behaviour. Belugas and bowheads were engaged in directed travel and diving near and under the ice. Five beluga dives were timed and found to have an average duration of 106 ± 61 s (± SD) and a range of 30 - 197 s. One bowhead under-ice dive was timed and had a duration of 417 s. The under-ice dives are consistent with feeding behaviour observed for belugas and bowheads in other ice-edge locations. We hypothesize that higher prey densities along the Franklin Bay ice edge than in the adjacent open water may attract belugas and bowheads to the ice edge in June. Further research is needed to identify the abundance and type of prey species consumed and to assess the relative energetic importance of spring ice-edge feeding to the eastern Beaufort Sea beluga and bowhead populations.

In its most recent assessment of global climate change, the U.S. National Academy of Sciences concluded, “A strong body of scientific evidence shows that climate change is occurring, is caused largely by human activities, and poses significant risks for a broad range of human and natural systems.” Impacts and rates of change are greatest in the Arctic, where temperatures have been increasing at about twice the global rate over the past four decades. The rapid decline in summer sea ice cover in the past decade has outpaced scientific projections and is drawing international attention to emerging commercial development and transport opportunities previously blocked by the frozen sea. The Arctic is therefore a bellwether for how climate change may reshape geopolitics in the post-Cold War era. The trend toward seasonally open waters is driving increased interest and investment in oil and gas exploration, shipping, and fishing in the Arctic. The recent economic recession has not affected these developments significantly, as they were always intended to be middle- to long-term developments following the progression of sea ice retreat. Indeed, high oil prices and advances in technology continue to support the drive toward offshore drilling in Arctic waters. The global economy, which has begun to show signs of recovery, is likely to rebound long before oil and gas exploration and shipping could be scaled up in the Arctic. China, India and the rest of the developing world’s growing middle classes will need oil and gas and other resources, and the world’s shipping routes are already so congested that the development of northern shipping routes is not a question of if, but when. In response to these changes, many of the Arctic states have begun to re-examine their military capabilities to operate in the Arctic region. Some have started to rebuild their military forces, while most of the other states are drawing up plans to begin the rebuilding process. Multilateral organizations and non-Arctic states are also looking for new roles in the Arctic. All of these actors are attempting to come to terms with the meaning of Arctic security, a concept that was relatively simple during the icy decades of the Cold War. Recent national policy developments arising from the effects of climate change on the Arctic commons demonstrate that climate change is indeed a national and international security interest in the traditional strategic sense. As the emerging Arctic security environment is in a very early stage of development, whether it will ultimately be predominantly cooperative or predominantly competitive remains an open question. Although the Arctic states invariably emphasize their desire to maintain a cooperative environment, several have stated that they will defend their national interests in the region if necessary. To gauge the geopolitical winds in the Arctic, this study catalogs and analyzes dozens of major policy statements and actions by the Arctic states, other states with Arctic interests, and multilateral organizations between 2008 and 2012. As a framework for interpreting the totality of these statements and actions, we compare geopolitical developments to date with three future security scenarios posited by the Arctic Council in its Arctic Marine Shipping Assessment 2009 Report. We adopt these scenarios as testable hypotheses for the purposes of this study: Hypothesis 1: There is no emerging security environment and the circumpolar states have no new interests that would increase competition or conflict in the region. If this hypothesis is correct, a close examination of the actions of the circumpolar world should reveal no significant new foreign and defense policies and defense procurement decisions in relation to the Arctic. Hypothesis 2: While showing renewed interest in the Arctic, the interested states are committed to developing and strengthening multilateral instruments of cooperation. New military capabilities are directed towards building local constabulary capacity and largely eschew escalation of war-fighting capability. Hypothesis 3: Increasing accessibility to Arctic resources because of climate change, along with a growing and increasingly modern military presence of strategic rivals in the region, becomes a recipe for competition and potential conflict. Under this hypothesis, the circumpolar states should be actively examining their core interests in the region, expressing concern over what other states are planning or doing in the region, and developing more assertive northern defense postures, including rebuilding their northern war-fighting capabilities. It is also expected that the various actors would be commencing the process of developing new defensive relationships and either strengthening old alliances or building new ones. We assess which of these hypotheses most closely resembles the behavior of the key actors as revealed in their statements and actions. On the basis of the prevailing scenario(s), we consider the potential for instability and conflict in the Arctic and offer recommendations on how the states should proceed to ensure the region develops in a cooperative and peaceful manner. ...

Foreword: Those monitoring the effects of climate change agree that the pace of environmental transformation currently taking place in the Arctic is unprecedented. As this report shows, such changes provide opportunities for business in areas as diverse as energy extraction, shipping and tourism. But these opportunities will only be fully realised if the businesses involved are able to manage the substantial, and unique, risks which exist in the region. There will be winners and losers as the impacts of climate change continue to shape the Arctic future. One thing that stands out most clearly from this report is the significant level of uncertainty about the Arctic's future, both environmentally and economically. Some of the technologies that will help to shape that future, such as those involved in deep water drilling and ice management are already tried, while others are still in their infancy or yet to be developed. Risk management clearly has a critical role to play in helping businesses, governments and communities manage these uncertainties and minimise risks. However, to do so effectively requires the most up to date information to analyse and control risks; there is a clear need for sustained investment in Arctic research. The 'known-unknowns' of the High North present particular challenges for those involved in exploration and extraction. The Arctic is a frontier unlike any other, and the industries and companies it attracts will need to develop and implement robust risk management systems to meet these challenges and manage both their carbon and environmental footprint on this pristine setting. The environmental implications of further development of the region are significant, reaching far beyond the immediate Arctic region itself. How, for example, will developments in hydrocarbon exploration and extraction align with commitments to reduce global greenhouse gas emissions and the need to increase our use of renewable energy? As recent events have shown, deep water exploration can have devastating consequences on local environments. The ability to contain and manage the fall-out from disasters is affected by issues including access, support infrastructure and cross-border political and legal requirements. Given that several states have jurisdiction over different parts of the Arctic, it will become even more important to develop and agree to clear governance frameworks to allow effective and co-ordinated responses to disasters. This report explores how fluctuations in energy prices have driven, and will continue to drive, the pace of exploration in the Arctic and the importance of both political stability and public support in attracting future investment. The businesses which will succeed will be those which take their responsibilities to the region's communities and environment seriously, working with other stakeholders to manage the wide range of Arctic risks and ensuring that future development is sustainable. Executive Summary: Rapid and disruptive change in the Arctic environment presents uneven prospects for investment and economic development. All across the Arctic, changes in climate will create new vulnerabilities for infrastructure and present new design challenges. The Arctic is likely to attract substantial investment over the coming decade, potentially reaching $100bn or more. However, given the high risk/potentially high reward nature of Arctic investment, this figure could be significantly higher or lower. Uncertainties and knowledge gaps exist around the nature of environmental change, the geological potential of the Arctic and environmental baselines, as well as seabed mapping, and how to deal with the risks of significant Arctic industrial activity. Arctic conditions will remain challenging and often unpredictable. Many of the operational risks to Arctic economic development - particularly oil and gas developments, and shipping - amplify one another. At the same time, the resilience of the Arctic's ecosystems to withstand risk events is weak, and political and corporate sensitivity to a disaster is high. The environmental consequences of disasters in the Arctic are likely to be worse than in other regions. Given the Arctic's iconic status and sensitive environment, Arctic development is often politically contentious, with sometimes opposing interests and perspectives between local, national and international levels. Political support for development will continue to represent an uncertainty for businesses seeking to invest in Arctic projects. The challenges of Arctic development demand coordinated responses where viable, common standards where possible, transparency and best practice across the north. These frameworks need to be in place to enable sustainable development and uphold the public interest. Companies operating in the Arctic require robust risk management frameworks and processes that adopt best practice and contain worst case scenarios, crisis response plans and full-scale exercises.

Introduction ... The Main Estimates presented to the Legislative Assembly represent the Government of Nunavut’s proposed appropriations for the 2012-2013 fiscal year for planned operations and maintenance expenditures. The Main Estimates reflect the priorities of government and is also consistent with departmental Business Plans. The Main Estimates detail all expenditures projected to be incurred and all revenues projected to be earned, during the twelve-month period beginning April 1, 2012 and ending March 31, 2013. This document, along with the Budget Address, Capital Estimates, and departmental Business Plans, constitute the 2012-2013 Budget of the Government of Nunavut. The Government implemented the accrual based budgeting method on a non-consolidated basis in fiscal year 2007-2008. ... The following Summary Financial Reports have been included in the 2012-2013 Main Estimates: Summary of Operations: expenditures based on an accrual basis, which includes capital expenditures not transferred to tangible capital assets, interest portion of lease payments and amortization of capital assets. Summary of Cash Flows: provides information on how the activities of the Government have been financed and how its financial resources have been used during the fiscal year on a cash basis. Summary of Changes in Net Debt: reconciles surplus/deficit income used in the acquisition of capital tangible assets recorded in the financial statements. The three summaries listed above are the first step in implementing the accrual based budgeting method and include accounting for revolving funds not included in the Summaries of Operations and Maintenance and Capital Expenditures. ... The three summaries should be considered strictly for information purposes only. Amortization expenses have been included in the departmental summary as a non-voted item in the 2012-2013 Main Estimates. The Legislative Assembly approved the Appropriation (Capital) Act 2012-2013 in October 2011.... The Legislative Assembly is requested to appropriate funds at the departmental level for operations and maintenance expenditures for the fiscal year ending March 31, 2013. The estimated expenditures identify the total operating requirements for individual departments, and additional descriptive information on departmental expenditures is provided by branch. Basic descriptions of these departmental branches are included in the Main Estimates to enhance the understanding of public expenditures and ongoing responsibilities of program managers. This document provides the Legislative Assembly with information on operations and maintenance expenditures at the control object level for compensation and benefits and grants and contributions, and at the standard object level for other expenditures. Revenue is presented at a summary level by major revenue category. Detailed information relevant to the Main Estimates is provided in the following areas for each department, as applicable: Accounting Structure Chart (how the department's financial accounts are organized); Department Summary (including mission and graph on the allocation of proposed expenditures to major branches); Branch Summary (appropriation requirements by control object and standard object); Grants and Contributions; Information Items; Regional Distribution of Budget. ... The financial information in the Main Estimates is presented on a comparative basis, at the government, department and branch level for the 2011-2012 Main Estimates, 2011-2012 Revised Estimates and 2010-2011 Actual Expenditures. The 2011-2012 Revised Estimates includes the 2011-2012 Main Estimates and the approved 2011-2012 Supplementary Appropriation (O&M) Act No. 1 and No. 2. The 2011-2012 Revised Estimates for capital expenditures have been updated to include appropriations approved through the 2011-2012 Supplementary Appropriation (Capital) Act No. 1 and No. 2. The 2010-2011 Actual Expenditures are unaudited balances, and may not include audit ad justments which may be reflected in the Public Accounts 2010-2011. In order to maintain the relevancy of the comparative figures, the 2011-2012 Main Estimates, 2011-2012 Revised Estimates and 2010-2011 Actual Expenditures have been restated to conform with changes to the accounting structure of departments, transfers of functions between departments, and transfers of functions between branches within departments. Appendix V details the restatements required to the 2011-2012 Main Estimates and 2011-2012 Revised Estimates resulting from the transfer of functions between departments. ... The 2012-2013 Main Estimates, Business Plans and Budget Address are available on the Internet through the Government of Nunavut home page (www.gov.nu.ca). In addition to the Main Estimates, which are voted on by the Legislative Assembly, this document contains Estimates of Expenditures for both Territorial Corporations and Statutory Bodies. The budgets for these public agencies have been incorporated into the 2012-2013 Main Estimates for information purposes only. ... (Au)

Mr. Speaker, I rise to present this government's budget for the coming fiscal year. In my first budget speech, I said that this government was moving forward prudently in building a sustainable territory. At the time, the global economy had just plunged into a serious recession. A cautious approach seemed best. Prudence was the central idea for the second and third budgets and it remains my policy today. With the passage of time, Mr. Speaker, we can see that this cautious approach of prudent financial management can build a solid foundation for our future. In this sensible approach, we live within our means, continuously improve our financial management, use debt appropriately, and plan for the future that we desire and deserve. Our sensible approach is paying dividends. Today, we project a small surplus for the year ahead. Here is our fiscal situation. For the current year, we project spending of $1.45 billion, and revenues at $1.37 billion. In my last budget, I anticipated a deficit of $50 million. Today, including adjustments for revolving funds, capital-plan carryovers, and our $25 million contingencies fund, I expect the deficit could fall to $34 million. Next year, the government plans to spend $1.34 billion, and to receive $1.47 billion. After adjustments for revolving funds, capital-plan carryovers and contingencies, we forecast a surplus of $37.7 million. Moreover, the contingency fund, set at $78 million, cushions our surplus. Our forecast surplus depends on our ability to collect our anticipated revenues, and to control our spending. I will address the spending issues in a few minutes. On the revenue side, we face two risks. The first - the federal government could change our financial arrangements. The second - the economy might not grow as we have forecast. Fully 92 per cent of our revenue comes to us from the federal government. The Territorial Formula Financing arrangement accounts for 86 per cent of our revenue. With a devolution agreement, we could reduce our dependence on the federal government. Until that time, this arrangement will remain our primary source of funds. I can assure the House that discussions on renewing our arrangement beyond 2014 are progressing well. We have received assurances from the federal government that the renewal will occur with no cutbacks. We look forward to concluding a new agreement that transparently reflects our real expenditure needs. While the first risk appears minimal, we cannot say the same about the second. The Nunavut economy has grown strongly over the long term, averaging 4.5 per cent per year. Our economy will have doubled in little more than a decade. But our growth year-over-year is volatile. With a short construction season, large projects can slip from one year into the next, which affects the timing of our revenues. There is also uncertainty about the mining sector. Although the Meadowbank gold mine is operating, Newmont has put its Hope Bay gold mine on hold. At the same time, exploration continues elsewhere. Overall, I am encouraged by our very real potential. Ultimately, mining investment will probably accelerate, producing jobs and revenue. Until then, however, we must remain vigilant about our fiscal situation. Looking beyond the current situation, let me discuss the approach that this government has chosen toward the remainder of our mandate. The term of this Legislative Assembly will expire in about 18 months. During this time, this government will continue to pursue the objectives defined in the Tamapta action plan. Generally, I group our work under four headings: An improved financial management, a better quality of life, a sustainable approach to development, and an improved ability to define, enable and manage our collective growth. Improved financial management tops my list. We are steadily improving our ability to manage taxpayers' dollars, and will improve further. This improved capacity is crucial to our long-term goals for development. And it is essential if we are to realize our full potential as a self-governing people. ... (Au)

Narwhals (Monodon monoceros) are gregarious, toothed whales restricted to the Arctic, where habitats are changing and shipping traffic is increasing. Challenges associated with the remoteness of narwhal populations and the general difficulty of studying deep diving mammals have resulted in a lack of knowledge of narwhal social behaviour, which can only be rectified with intensive, direct and systematic observations. I studied the grouping patterns and vocal behaviour of narwhals using non-invasive methods and developed new statistical tools to analyse the data. The field work was conducted at Bruce Head, a peninsula at the mouth of Koluktoo Bay, Nunavut, during the summers of 2006-2008. Shore-based observations were used to delineate narwhal groups by sex and age class. Narwhals travelled in clusters of 1-25 individuals of mixed sex and age class. Narwhals entered the bay in larger groups than they exited. The coloration of narwhal's backs on photographs was used to estimate their age and investigate their association with individuals of similar age. To analyse these data, I developed statistical methods that examine the distribution of observations in time and their associated characteristics. Using these methods, I found that narwhals form groups with individuals of similar age. The variability and the context of usage of narwhal calls were examined from underwater recordings. Some physical characteristics of narwhal whistles seemed behaviour-specific. Both whistles and pulsed calls might serve in individual- or group-recognition. Finally, given that there is a need for sustained, local monitoring of narwhals, I explored the potential of passive acoustic methods for narwhal monitoring. An automated detector was able to correctly identify narwhal calls in a 25-day continuous recording. There was a correlation between the number of calls manually detected in non-continuous recordings and the number of narwhals observed during the recordings. Non-invasive methods can provide valuable insight into the social organization, communication and movement patterns of large numbers of non-disturbed cetaceans. (Au)

The neurotoxin methylmercury (MeHg) is found in some Arctic freshwater fish and marine mammals at concentrations that may be harmful to Northern Peoples consuming these animals. The key process resulting in mercury (Fig) contamination of organisms is the methylation of inorganic Hg(II) to MeHg, which is much more readily bioaccumulated and biomagnified than Hg(II). Thus, the objective of this research was to determine the sources of MeHg to Arctic freshwater and marine ecosystems by identifying the processes controlling the production and cycling of this toxin. Three aspects of the Hg biogeochemical cycle were examined using enriched Hg stable-isotope tracers: MeHg photodemethylation in lakes, MeHg cycling in wetlands, and Hg(II) methylation in marine waters. The role of light quality in MeHg photodemethylation was experimentally determined, demonstrating that ultraviolet radiation (UV) and not visible light, as has been previously suggested, is the principal driver of this process. We propose a simple model to quantify whole-lake MeHg photodemethylation fluxes, based on experimentally determined photodemethylation rate constants for the different radiation wavebands (UV-B, UV-A and visible), MeHg concentration, and attenuation of solar radiation in the water column. We used a mass-balance approach, quantifying atmospheric inputs, losses from photodemethylation and accumulation in the water column pool, to demonstrate that MeHg production in two different High Arctic wetlands ponds (1.8-40 ng/m²/d) is comparable or greater than what has been measured in freshwater ecosystems in temperate latitudes. MeHg production in pond sediments was controlled by Hg(II) availability and the potential rate of Hg(II) methylation. MeHg concentration in the water column of surveyed ponds was positively correlated to MeHg concentration in sediments and proxies of anaerobic microbial activity, but inversely correlated to UV-A exposure, indicating that the cycle of MeHg in these ponds is driven by Hg(II) methylation in sediments and MeHg photodemethylation in the water column. Production of MeHg and dimethylmercury in seawater was detected at all sites sampled in the Canadian Arctic Archipelago. Using measured rate constants of Hg(II) methylation and MeHg demethylation in a simple model, we conclude that water column methylation accounts for ~50% of MeHg occurring in Arctic marine waters.

This thesis was developed within the framework of a monitoring program for Saglek Bay, Labrador, Canada. Extensive polychlorinated biphenyl (PCB) contamination in soil and sediment associated with a former Polevault Line military station was identified at Saglek in the 1990s (ESG, 1997). PCB impacted soil remediation was carried out between 1997 and 1999 and thus, the terrestrial source of exposure has been removed. Ecological studies showed that PCBs remained in the coastal marine food web (Kuzyk et al., 2005a) and the terrestrial food chain (ESG, 2005; 2007). Recent evidence indicates that the concentrations in the marine environment are decreasing (Brown et al., 2009). Research for this thesis was conducted to evaluate the effects of PCBs on biomarker responses in wildlife at Saglek, and to evaluate the effectiveness of field verification of effects predicted at the screening risk assessment stage by comparing the results of a traditional food chain model approach to a biological effects based weight of evidence approach. Hazard quotients indicated that there was a potential for adverse risks to shorthorn sculpin at Saglek Beach (hazard quotient=1.6) in 1998/99 but adverse risks were unlikely (hazard quotient=0.9) in 2006/07. The biological effects based weight of evidence assessment supported the hazard quotient methodology indicating an intermediate risk to shorthorn sculpin in 1998/99 and a low risk in 2006/07. For black guillemots, the hazard quotients indicated that adverse risks were likely for both 1998/99 (hazard quotient=2.1) and 2006/07 (hazard quotient=1.2). The biological effects based weight of evidence assessment supported the hazard quotient indicating an intermediate to high risk to black guillemots for these time periods. The hazard quotients calculated for deer mice using the dietary approach (2.3) and the tissue residue approach (2.1) indicated that adverse effects to deer mice at Saglek Beach are likely. Results of bone mineral density analysis supported this conclusion but thyroid histomorphometry and histopathology did not. Despite the predicted health effects to black guillemots and deer mice at Saglek, the populations appear to be thriving. Measurement of population and/or community indices would be helpful in confirming the predicted adverse effects. A three tier iterative approach using hazard quotients, biomarkers, and population/and or community studies is recommended for large complex sites such as Saglek, where remediation strategies are expensive and potentially destructive to the environment. This thesis emphasizes field verification of adverse health effects predicted through the screening (i.e., hazard quotient) assessment stage and supports an iterative tiered approach to ecological risk assessment.

Dimethyl sulfide (DMS) and its oxidation products, which have been proposed to provide a climate feedback mechanism by affecting aerosol and cloud radiative properties, were measured during onboard sampling campaigns in the Arctic in the Fall of 2007 and 2008. DMS concentrations were found to be localized with highly variable concentrations ranging from below detection limit (0.3 nmol/m³) to 14 nmol/m³. DMS flux was calculated based on surface water measurements conducted in open waters and yielded an average of 0.7 µmol/m²/d along Baffin Bay. DMS oxidation products, sulfur dioxide (SO2 ), methane sulfonic acid (MSA), and sulfate (SO4--) in aerosols were also measured. Concentrations of atmospheric sulfur compounds during the campaign were [SO2] = 2.7-135 nmol/m³ (2007) and 0.28-27 nmol/m³ (2008), [MSA] = 0.03-0.07 nmol/m³ (2007) and 0.02-0.14 (2008), and non-seasalt sulfate [nSS-SO4--] = 0.5-7.0 nmol/m³ (2007) and 0.01-2.0 nmol/m³ (2008). Median daily biogenic SO2 and SO4-- concentrations obtained from stable isotope apportionment techniques were found to be approximately 0-105 nmol/m³ and 0-1.7 nmol/m³ respectively for 2007 and approximately 0-15 nmol/m³ and 0-0.4 nmol/m³ respectively for 2008. Applying conditions for significant new aerosol formation given in Pirjola et al. (1999), the study shows that sufficient biogenic SO2 is released from DMS oxidation to form new aerosols in clean air conditions. Pre-existing aerosols act as an additional condensation sink that prevents new aerosol formation in air parcels polluted by ship stack emissions. These results suggest that the predicted increase in primary productivity and DMS marine emissions could significantly affect the climate regionally. However, an increase in ship traffic would decrease locally the cooling effect of DMS emissions. (Au)

This thesis focuses on the understanding of patterns and variability of sediment and fresh water delivery from land to sea, and sediment dispersal in the marine basins of two fjords in Northern Labrador. Multibeam and sub-bottom acoustic data and sediment cores were collected in Nachvak and Saglek fjords. Sediment cores were sub-sampled for X-radiography, grain size, and radiochemical analysis (based on the particle-bound radioisotopes 210Pb and 137Cs,), to study sedimentary structures and determine sediment accumulation rates. Results show that the sediments are generally mottled and fine grained. Sediment accumulation rates are on average 0.21 cm/y in Nachvak fjord and 0.26 cm/y in Saglek Fjord with temporal resolutions ranging from 15 - 68 years in Nachvak Fjord and 12 - 49 years in Saglek Fjord. Mass accumulation rate values suggest that the majority of the sediment is accumulating in the center of the basins. Further analyses suggest that: postglacial sedimentation was on average constant in Nachvak Fjord; in Saglek Fjord sediment accumulation was more rapid during the last ~l00 y as compared to post-glacial times; the main sediment source in Saglek fjord is from rivers with extensive catchments that lack glaciers, and in Nachvak fjord from smaller rivers with steep, small and presently glaciated catchments as well as from additional sources such as from the erosion of glaci-marine terraces.

The politics of international law should be seen as a constant condition of international affairs within which the practices of international law and world politics unfold. This work aims to uncover several ways to understand the politics of international law, and in particular, to understand how law and politics interact within extended foreign policy sequences. These long foreign policy episodes are generally centered on a particular component, or body of, international law. Yet they are also subject to numerous elements and functions of international law which give form and content to a state’s policy development. These include complex compliance decisions, repeated public justifications over the terms of legal validity, learning what the law requires to meet thresholds of compliance, and states' engaging in forms of legal rhetoric known as creative legal arguments: legal justifications that attempt to change international law when states face difficult policy choices. These various areas of international law highlight, in part, how international law 'works', or has effects within world politics. This project attempts to consolidate recent scholarship in this subject area by employing eclectic theorizing to explain the politics of international law as it unfolds in policy deliberation and choice. This task involves utilizing many insights from social constructivism and critical international legal theory, but also capturing the central ideas of legal realism, rationalism, and interactionalism in their ability to explain compliance decisions. From this point of departure, this work attempts to build theoretical bridges through a genuine interdisciplinary engagement with international relations and international law. Such an endeavor brings clarity to empirical events and historical legal phenomena. To demonstrate this claim, the analysis offered evaluates the foreign policy sequence in Canadian legal policy over the Arctic waters known as the Northwest Passage, a forty year legal dispute between Canada and the United States. The case study sheds light on how international law-making unfolds over time, by virtue of the numerous iterations between Canada and the United States in bi-lateral settings, international conferences, and the third codification conference on the Law of the Sea (UNCLOS).

Since 2003, all underway multibeam and sub-bottom data from the Canadian Coast Guard Ship Amundsen has been posted online within approximately six months of the end of each cruise. Two custom interfaces were developed to allow users to view the data. The first was stripmaps, showing 25 by 5 kilometre mapsheets, with two different sun-illuminations for bathymetry, backscatter, and properly referenced sub-bottom data. The second interface, providing access to 15' latitude by 30' longitude mapsheets, was implemented in 2006. This interface allowed users to download the bathymetric and backscatter data at 10 metre resolution. While this interface matched the underlying data management scheme implemented at the University of New Brunswick, the zoom and pan capability was at a fixed scale with limited contextual data. In the past few years, with the introduction of web-based geographic information systems (GIS) (e.g. Google Maps, Yahoo Maps, Bing Maps), there have been thousands of maps published online. These online GIS programs are a suitable platform to display the seven years of Amundsen coverage within the context of the GIS-served satellite imagery and allow the user to freely browse all data in a familiar interface. The challenge, however, for serving up third party data through these map engines is to efficiently cope with the multiple zoom levels and changing resolutions. Custom tiling software was developed to take all the raw data from the seven years of Amundsen (and others') multibeam coverage and convert it into multiple scale resolution images suitable for interpretation by Google Maps. The images were stored in a pyramid structure utilizing Google's map projection and uniquely named to reflect their georeferencing and resolution. This image pyramid is then accessed by Google Maps according to the user's current zoom level to optimize visualization. This multi-resolution data is served up on demand from the University of New Brunswick for dynamic overlay on Google's satellite data. Point overlays were developed to show each stripmap, adding to the functionality of the website by providing users the full picture of the seafloor (topography and underlying sediments). This web interface allows any interested parties to easily view multibeam and sub-bottom data from the Pacific Ocean through the Canadian Arctic Archipelago and into the Atlantic Ocean. The broad overview helps to understand regional trends and then focus on areas of interest at high resolutions to see particular features. The web interface also provides a link to the 15' by 30' mapsheet model with full source traceability and download capability. (Au)

L'exposition aux contaminants de la chaîne alimentaire tels que le méthylmercure et les biphényles polychlorés (BPC) peut induire un stress oxydatif et des dommages à l'ADN, lesquels sont considérés comme des événements primaires dans la carcinogenèse. La population inuit est exposée à des doses élevées de ces contaminants de la chaîne alimentaire par leur alimentation traditionnelle qui comprend plusieurs espèces prédatrices appartenant à la chaîne alimentaire marine. Le but de notre étude était de mesurer à l'aide du test des comètes les cassures dans l'ADN de lymphocytes obtenus d'adultes de la population inuit du Nunavik ayant participé à l'Enquête sur la santé des Inuit en 2004. Nous voulions également examiner la relation entre les concentrations sanguines de mercure ou les concentrations plasmatiques de BPC et les bris à l'ADN lymphocytaire, en contrôlant pour les habitudes de vie, la nutrition et différents autres facteurs potentiellement confondants. Nous n'avons pas trouvé de relation entre le dommage à l'ADN des lymphocytes et les concentrations sanguines de mercure ou les concentrations plasmatiques de BPC. Nous avons par contre observé une corrélation statistiquement significative entre la consommation d'alcool chez les participants et le dommage à l'ADN. Les participants qui consommaient de l'alcool au moins une fois par semaine avaient un dommage à l'ADN lymphocytaire significativement plus élevé que ceux consommant de l'alcool moins d'une fois par semaine. De plus, l'âge des participants était négativement corrélé avec le dommage à l'ADN, ce qui pourrait refléter un effet protecteur d'un ensemble de facteurs chez les participants les plus âgés dont une plus grande consommation d'aliments traditionnels et des consommations plus faibles d'alcool et de tabac. Ces résultats suggèrent donc que la consommation d'alcool augmente le dommage basal à l'ADN chez cette population inuit, mais que ni le méthylmercure ni les BPC ne semblent avoir un effet significatif sur le dommage à l'ADN des lymphocytes dans cette population.

Microorganisms make up 90 % of organic matter in oceans. Among them, the crenarchaeon Candidatus Nitrosopumilus maritimus was recently isolated, revealing that members of its clade could be responsible for much of the nitrification, in the nitrogen cycle. This biochemical potential can be detected in Crenarchaeota using molecular tools, estimating the presence and the expression of the ammonium monooxygenase subunit A gene (amoA). The North Water area (Northern Baffin Bay, between Ellesmere island and Greenland) has a biological productivity among highest in the Arctic, which is thought to be linked to nitrate inputs, the final product of nitrification. Results show that the amoA gene was abundantly present and expressed, that its distribution and expression were influenced by some environmental variables and that amoA phylogenetic diversity differed between DNA (presence) and cDNA (expression) derived analyses.

Annuli formed within cementum, a mineralized tissue surrounding the root of mammalian teeth, are commonly used to age wildlife. Cementogensis is influenced by a number of physiological and environmental factors and therefore cementum is a tissue capable of recording life history. Mark-recapture data from the Western Hudson Bay population of polar bears ( Ursus maritimus ) allows comparison of observed life history events to patterns in cementum. Sources of variation in cementum growth were identified and protocols developed to reduce error and permit comparisons within and between individuals. Cementum growth in years when females are accompanied by cubs-of-the-year (COY) are significantly less than the year of pregnancy (paired t-test, x diff = 0.054, t = 8.16, df = 103, P < 0.001), and yearling accompaniment (x diff = 0.034, t = -3.88, df = 31, P < 0.001). The predictive model correctly classified COY for 0.73 of the females with COY, while pregnancy (0.71) and yearling (0.77) were correctly classified as non-COY. (Au)

This thesis characterizes the nutritional implications of climate change impacts on the traditional food system of Inuit in Nunavut, Canada. Both focus groups and food frequency questionnaires were used in collaboration with two communities to describe current climate change impacts on traditional food and define nutrient intake. Currently, both communities experience climate-related changes to important species which provide high levels of key nutrients. If climate changes continue to impact traditional food species, serious nutritional losses may occur unless healthy alternatives can be found. Policy should support Inuit communities to maintain optimal nutrition in the face of climate change. (Au)

La toxoplasmose, causée par Toxoplasma gondii et habituellement asymptomatique est l'une des infections parasitaires ubiquitaires les plus fréquentes chez l'homme. Jusqu'à 80% des enfants risquent de développer d'importantes séquelles lorsque l'infection survient chez la femme enceinte. La prévalence et l'incidence des infections récentes pendant la grossesse ont été déterminées chez les 1299 participantes au programme de dépistage et de prévention de la toxoplasmose entre 1994 et 2003 chez la femme enceinte au Nunavik (nord du Québec, Canada). Un total de 1860 grossesses issues de ces femmes âgées de 13 à 45 ans a été enregistré. La séroprévalence globale a été estimée à 50% durant la période de l'étude. Elle était de 42% chez les mères de moins de 20 ans et de 70% chez celles âgées de 40 ans et plus. Les prévalences ajustées sur l'âge étaient relativement stables en fonction du temps, mais étaient plus élevées dans l'Hudson (ouest du Nunavik) que dans l'Ungava (est du Nunavik). L'incidence cumulative, déterminée à partir des infections confirmées suite à la revue des dossiers des cas potentiels était de 1,7% parmi les femmes séronégatives. Ces chiffres démontrent que la toxoplasmose demeure un problème de santé publique dans cette région arctique du Québec. (Au)

Landfast ice is sea ice which forms and remains fixed along a coast, where it is attached either to the shore, or held between shoals or grounded icebergs. Landfast ice fundamentally modifies the momentum exchange between atmosphere and ocean, as compared to pack ice. It thus affects the heat and freshwater exchange between air and ocean and impacts on the location of ocean upwelling and downwelling zones. Further, the landfast ice edge is essential for numerous Arctic mammals and Inupiat who depend on them for their subsistence. The current generation of sea ice models is not capable of reproducing certain aspects of landfast ice formation, maintenance, and disintegration even when the spatial resolution would be sufficient to resolve such features. In my work I develop a new ice model that permits the existence of landfast sea ice even in the presence of offshore winds, as is observed in nature. Based on viscous-plastic as well as elastic-viscous-plastic ice dynamics I add tensile strength to the ice rheology and re-derive the equations as well as numerical methods to solve them. Through numerical experiments on simplified domains, the effects of those changes are demonstrated. It is found that the modifications enable landfast ice modeling, as desired. The elastic-viscous-plastic rheology leads to initial velocity fluctuations within the landfast ice that weaken the ice sheet and break it up much faster than theoretically predicted. Solving the viscous-plastic rheology using an implicit numerical method avoids those waves and comes much closer to theoretical predictions. Improvements in landfast ice modeling can only be verified in comparison to observed data. I have extracted landfast sea ice data of several decades from several sources to create a landfast sea ice climatology that can be used for that purpose. Statistical analysis of the data shows several factors that significantly influence landfast ice distribution: distance from the coastline, ocean depth, as well as the strength of offshore winds during nine out of the twelve months each year. Additionally, I identify regions where landfast ice appearance has been increasing or decreasing over the observed time span. (Au)

Cette étude présente de nouvelles données sur la déglaciation et l'évolution côtière holocène du sud-est de l'île de Southampton (nord de la baie d'Hudson). La déglaciation du secteur s'est produite entre 8,3 et 8,2 ka BP ce qui indique une déglaciation rapide et synchrone du nord-ouest et du sud-est la baie d'Hudson. La présence de chenaux marginaux sur du till indique un changement dans le régime thermique du glacier pendant la déglaciation, lequel a engendré le passage d'une glace à base tempérée à base froide. L'émersion est continue pendant l'Holocène et se poursuit encore aujourd'hui. Les plages soulevées de l'île sont particulièrement bien développées et sont situées dans les secteurs de roches calcaires. Un important épisode de crue d'eaux de fonte glaciaire a érodé de grandes séries de plages soulevées. Cette crue provenant d'une calotte glaciaire résiduelle située sur le plateau Melville correspond au dernier stade de la présence de glace sur l'île à 6,7-6,6 ka BP. Cette étude démontre aussi que le secteur de Coral Harbour n'est pas sensible à l'érosion pouvant être causées par des changements climatiques, car le village est construit sur du gneiss et sur une mince couche de sédiments sableux non gélifs.

Sources, seasonal patterns, and spatial variations of snowpack sulphate of the Prince of Wales Icefield, Ellesmere Island were assessed using delta 34S values. Snowpack sulphate concentration and delta 34S values diminished with elevation and inland distance suggesting the North Water Polynya was the major sulphate source with additional sources affecting specific regions. Dominant sulphate deposition was by below-cloud scavenging and/or gravity fallout resulting in dilution by snowfall. Snowpack delta 34S values in depth profile reflected seasonal cycles of marine biogenic, anthropogenic, and sea-salt aerosols with appreciable contributions of marine biogenic sulphate to virtually every depth horizon. A proximal April/May marine biogenic source is indicated, with DMS oxidation occurring near the marine boundary layer, and the possibility of additional oxidation at higher atmospheric levels. Different spatial patterns of MSA and DMS sulphate suggest the timing of oxidation and the transport of the two DMS oxidation products differ. (Au)

In western Hudson Bay, polar bears (Ursus maritimus) den primarily in riparian areas along banks of lakes, rivers and creeks adjacent to open lichen tundra sites. Habitat characteristics important for the establishment of dens included vegetation cover, slope, bank height and aspect. Forest fires were found to have significant impacts on denning habitat through removal of vegetation and degradation of permafrost that led to a decrease in the stability of denning habitat and increased rate of collapse of dens. Long-term population monitoring, den surveys and satellite movement data all indicate that bears do not use burned areas. Although the availability of maternity denning habitat is likely not limiting in this population at present, the potential threat of increased lightning and forest fire activity as a result of climatic warming could result in significant loss of critical maternity denning habitat and resource managers need to be aware of this potential threat.
