ASSESSING THE INFLUENCE OF A WARMING CLIMATE ON THE BIOTA OF ARCTIC FRESHWATER SYSTEMS
(2022-12-19)Understanding the effects of climate change is particularly important for northern regions, where temperatures have increased by considerably more than that of the global average since the start of the 20th century. As a ... -
Biofilm-Enhanced Treatment for Arctic Wastewater Stabilization Ponds Using Geotextile Substrate
(2013-08-20)In this thesis, a semi-permeable lining system was proposed to upgrade arctic wastewater stabilization ponds, acting as a biofilter. Although commonplace at lower latitudes, the effects of cold temperatures and short-duration ... -
CLOUD AND AEROSOL PROPERTIES MEASURED WITH A LIDAR IN THE HIGH ARCTIC AT EUREKA
(2010-12-13)The recently commissioned CANDAC Rayleigh?Mie?Raman Lidar (CRL) in Eureka, Nunavut, finished its first winter measurement campaign in 2010, during which over 900 hours of data was collected. A comparison of several inversion ... -
Decolonizing Marine Safety and Shipping in the Inuvialuit Settlement Region: Looking inwards and to Inuvialuit for insights for reconciliation
(2024-04-10)The governance of shipping in Inuit Nunangat has been evolving in response to a growing interest in polar navigation and a recognition that while such navigation is possible, it comes with unique risks and operating ... -
Dynamic Architecture in the Canadian Arctic
(2019-04-05)This thesis investigates changing conditions in the Canadian Arctic. Reduced yearly sea ice extent due to anthropogenic global climate change has spurred a significant increase in marine traffic within the Canadian Arctic ... -
Estimating Ship Transit Times in Ice-Covered Waters for Strategic Route Analysis and Search and Rescue Response Planning
(2024-07-30)Maritime traffic in the Arctic region is increasing as northern communities grow, tourism accelerates, and large resource development projects enter operation. Consequently, the number of vessels exposed to the navigational ... -
Human Health Risks Associated With Wastewater Treatment in Arctic Canada
(2020-08-27)This dissertation provides the first estimates of microbial health risks attributable to wastewater treatment systems in Arctic Canada. A participatory quantitative microbial risk assessment was designed to model a range ... -
AN INTERDISCIPLINARY ASSESSMENT OF COMMUNICATING SOCIAL AND NATURAL IMPACTS OF CLIMATE CHANGE IN THE CANADIAN ARCTIC
(2024-08-08)Accelerated climate warming has cascading effects on Arctic ecosystems and northern communities, resulting in an urgent need for adaptation and communication strategies across circumpolar regions. As such, Arctic amplification ... -
Interpretation of Arctic Black Carbon Measurements with a Chemical Transport Model
(2015-01-15)Black carbon is a pollutant of concern in the Arctic; however models struggle to accurately simulate its seasonal cycle observed from in-situ measurements. This work aims to examine the contribution of different types of ... -
INTERPRETING SATELLITE REMOTE SENSING, AIRCRAFT AND GROUND-BASED OBSERVATIONS OF AEROSOL USING A CHEMICAL TRANSPORT MODEL
(2020-01-16)Fine particulate matter (PM2.5) is the leading environmental risk factor for the global burden of disease. Black carbon (BC) and metal components are primarily responsible for the adverse health effects associated with ... -
Modelling Arctic Sea Ice and Ocean Processes in a Changing Climate
(2023-12-13)Warming four times faster than the rest of the globe, the Arctic region is experiencing rapid changes. At the heart of this amplification of anthropogenic climate change lies a strong coupling between the different components ... -
MODELLING THE RELATIONSHIP BETWEEN LIQUID WATER CONTENT AND CLOUD DROPLET NUMBER CONCENTRATION OBSERVED IN SOME LOW CLOUDS IN THE SUMMER ARCTIC AND ITS RADIATIVE EFFECTS
(2019-11-28)We investigated the microphysical properties of some low Arctic clouds and attempted to simulate the observed linear relationship between liquid water content and cloud droplet number concentration. The low clouds were ... -
Non-Parametric Statistical Tests for Differences in Fatty Acid Composition of Greenland Sharks
(2013-12-13)Variations in predator diets is important in ecology to help us understand their top-down effects on the ecosystem. In predator diets, their fatty acid signatures reflect the proportions of prey consumed. Since fatty acid ... -
NU Healing: Empowering the Margin(alized)
(2015)The correctional system in Nunavut ignores the systemic social dysfunction underlying criminality in the Territory that has been the result of several generations of social and cultural displacement. As a physical manifestation ... -
PATTERNS OF RUBISCO CONCENTRATIONS IN GLACIERIZED AND NON-GLACIERIZED ENVIRONMENTS ACROSS JONES SOUND, NU
(2022-11-21)Tidewater glaciers can enhance delivery of nutrients to the surface ocean. The Canadian Arctic Archipelago (CAA) has a high density of tidewater glaciers, but their influence on the marine environment, particularly ... -
Phosphorus Removal in Passive Cold Region Waste Stabilization Ponds
(2016-08-23)A majority of communities in the Canadian territory of Nunavut rely on passive waste stabilization ponds (WSP) for domestic wastewater treatment. Little research has been conducted on the treatment performance of these ... -
A Qualitative Case Study Of Relationships Between Public Health And Municipal Drinking Water and Wastewater In Coral Harbour, Nunavut
(2013-08-21)Wide health gaps exist between Canada’s Inuit population and their non-Indigenous counterparts in nearly all categories. Two basic public health protection principles in any community worldwide are access to safe drinking ... -
RECONSTRUCTION OF HIGH ARCTIC WINTER SURFACE ENERGY FLUXES
(2011-09-06)Throughout the late 20th and early 21st century, the global temperature has been on the rise, a process that has been accelerated in the Arctic. The Arctic surface temperatures have risen at a factor of 3 greater rate than ... -
A relationship between heat transfer to sea ice and temperature-salinity properties of Arctic Ocean waters
(1988)It is demonstrated that the characteristic temperature-salinity relationship shown by thermocline waters of the Arctic Ocean can be reproduced using a simple model based on transfer of heat directly from these waters to ... -
Shifting Ground: Addressing Environmental Instability through a Method of Two-Eyed Seeing in an Arctic Community
(2022-04-12)Given the necessity of addressing the impacts of climate today, research and practice must engage local ecological, cultural, and technical knowledge to drive meaningful and respectful research. Through field work and ...
