ECS02 - Conservation Challenges Facing Arctic Marine Wildlife
The Arctic marine environment is rapidly shifting due to climate change and increased human pressure. Marine wildlife are faced with multiple concurrent environmental pressures, such as habitat loss, shifting prey species, and novel competitors and predators, as well as new human-induced pressures such as pollution, invasive species, and disturbance. Moreover, marine wildlife are an important source of subsistence food for Inuit throughout Inuit Nunangat, so decreased health or abundance of marine wildlife can directly affect the people who rely on these animals. This session will include presentations on the variety of new conservation challenges facing Arctic marine wildlife, including fish, seabirds, and marine mammals. Presentations will focus on identifying these conservation challenges, but also on working towards finding solutions that benefit marine wildlife and Inuit who rely on them.

ECS11 - Wildlife Health Ecology in a Changing Arctic
Wildlife health is essential for ecosystem health, biodiversity conservation, food sovereignty and security, and sociocultural health. Arctic wildlife are currently facing multiple threats, including climate change, shifting animal and plant phenology, disturbance, and the invasion and establishment of novel species. The results are dramatic shifts in wildlife health and emergence of infectious diseases. Interdisciplinary, holistic research with a One Health approach is required to better understand these threats and drive actionable recommendations. This session invites a diversity of views, from community, ecology, wildlife management, human health and policy sectors. We aim to explore different facets of wildlife health ecology during a period of environmental change and shifting societal priorities. Themes will focus on the links between wildlife health and their ecology, including disease ecology, nutritional ecology, and drivers of population health.

ECS60 - Arctic ecotoxicology: Sources and impacts of contaminants in polar ecosystems
The polar regions face major environmental challenges from contamination by a multitude of potentially toxic substances. Although remote from major industrial areas, these regions are subject to significant pollution resulting from atmospheric and oceanic transport of contaminants, as well as from emerging local activities such as natural resource extraction and tourism. The presence of contaminants in the Arctic endangers the region's sensitive ecosystems, with biological and ecological effects that are still poorly understood. This session aims to offer a comprehensive perspective on Arctic ecotoxicology, addressing pollution sources, their modes of dispersal, and their impacts on wildlife and human communities. Contaminants in the Arctic can be highly variable and their potential impacts can be exacerbated by climate change. Among the most concerning are persistent organic pollutants (POPs), heavy metals, microplastics, polycyclic aromatic hydrocarbons (PAHs), and per and polyfluoralkyl substances (PFAS). These have been found in both marine and terrestrial organisms and find their way into ecosystems and organisms via the aforementioned sources. The accumulation of contaminants in Arctic food webs can have severe biological consequences. The effects are varied and can include endocrine disruption, oxidative stress, effects on reproduction or the immune system, among others. This session will explore the pathways and toxicological effects of contaminants on various organisms such as marine mammals, fishes and seabirds, as well as plankton communities, which form the basis of food chains. Local populations, particularly Indigenous communities, are directly affected by the presence of these contaminants. We also invite researchers working on the health effects of contaminants on Arctic Indigenous populations, on risk management policies put in place to limit exposure to contaminants, and those working to integrate traditional knowledge systems into strategies for monitoring and adapting to environmental contamination, to submit an abstract for this session.

ECS64 - Changing coastlines and community resilience in Nunavut
This special session highlights the early outcomes and innovations from a collaborative coastal adaptation project in Nunavut, involving Inuit organizations, northern communities, academic researchers, the private sector, and territorial and federal partners. The initiative integrates community-based monitoring, coastal hazard modelling, and knowledge transfer to inform and support local and regional decision-making. Presentations will explore the intersection of Inuit Qaujimajatuqangit and scientific methods in assessing risk to coastal hazards, and in co-developing adaptation tools and pathways to strengthen community resilience. We welcome contributions from all components of the project or other similar projects in Nunavut, including (but not limited to): Inuit knowledge and observations, field-based environmental monitoring (permafrost, sea ice, hydrodynamics, etc.), hazard mapping, wave and water level modelling, early warning systems, and adaptation strategies developed in partnership with communities. This session aims to foster cross-sector dialogue, highlight the value of co-produced knowledge, and showcase applied solutions to climate adaptation in Arctic coastal regions.

OTH15 - Atmosphere-sea ice-ocean interactions in a changing Arctic
The Arctic is warming at up to four times the global rate, which is driving a dramatic reduction in Arctic sea ice. As the manifestation of both thermodynamic and dynamic processes across the atmosphere-sea ice-ocean system, sea ice is susceptible to changes in both the atmosphere and ocean that in turn modulate its extent, mobility and thickness. Changes to the ice pack have cascading effects on the entire marine system, such as altering biogeochemical processes, affecting the livelihoods of Inuit, and impacting the maritime industry that operates in Arctic waters. Hence it is critical to understand the processes that act across the ocean-sea ice-atmosphere system and how they modulate ice pack characteristics at all spatial and temporal scales. This broad session covers the oceanographic and atmospheric processes that influence the sea ice cover, and the physical properties of the snow-covered sea ice itself. Studies based on local knowledge, in situ observations, remote sensing and/or modelling are invited. Co-Chairs: David Babb, University of Manitoba Alex Cabaj, Environment and Climate Change Canada
OTH43 - Resilience and Innovation: Addressing Food Security in the Arctic through Community-Led Solutions
Food security in the Arctic is shaped by the complex interplay of climate change, high transportation costs, infrastructure gaps, and the erosion of traditional food systems. This session centers the leadership and voices of northern Indigenous communities to explore environmental, cultural, and technological factors affecting access to nutritious, affordable, and culturally appropriate food. Case studies-such as Gjoa Haven's Naurvik greenhouse and Cambridge Bay's fish processing facility-highlight the power of partnerships between Indigenous knowledge holders and researchers to co-develop sustainable, locally driven solutions. We invite submissions on: land-based harvesting, Controlled Environment Agriculture, renewable energy integration, community-led monitoring, Arctic char fisheries, climate impacts, affordability and tariffs impacts, commercialization risks, youth engagement, and Indigenous food governance. Co-Chairs: Christine Cox, Arctic Research Foundation Tom Henheffer, Arctic Research Foundation
OTH45 - Canadian Antarctic Research
Canada's reputation for Arctic science is well-established and positions our country to lead internationally on relevant issues.

WBE49 - Indigenous-Led Hunter and Guardian Programs Are Worth Investing in For Communities and Governments
Four Indigenous-led hunter and guardian programs-Dechinta Centre for Research and Learning, Ittaq Heritage and Research Centre, Imaryuk Monitors, and the Ni Hat 'Ni Dene Guardians-have collaborated to develop an approach for estimating their programs' economic return on investment (ROI) from the Payer's perspective. They created tools to track outcomes related to food security, health, mental health, ecological conservation, economic development, and overall wellbeing, with near real-time results shared via dashboards. This session will present their evaluation tools, ROI methodologies, and findings, and offer a roadmap for similar programs. Their approach shows a positive ROI for federal, territorial, and provincial governments, and Canadian society. The format includes: 1) frameworks and methods; 2) program findings; 3) roadmap for similar programs; and 4) an interactive discussion and mini-training session for Indigenous-led programs aiming to improve wellbeing in Northern Indigenous contexts.
