Estuaries and coastline along the western Hudson Bay are summer habitat for the Western Hudson Bay (WHB) beluga population. The habitat features associated with beluga migration to and use of the Nelson, Seal and Churchill estuaries every summer are not fully understood, but theories include that shallow waters provide protection from predators, warm estuary water has metabolic benefits for growth and molting, and that estuary habitat is rich in prey. Spatial analysis and mapping programs have been used to determine key habitat areas for marine mammals and can be a useful tool for understanding WHB beluga habitat. \r\n\r\nBeluga locations will be entered in to ArcMap from georeferenced aerial photos collected during the summer 2018 BaySys cruise. Relationships between location, habitat characteristics (distance to coast, tide), and beluga features (age class, group size) will be examined by testing for patterns in distribution. These data will reveal beluga habitat associations in and out of estuary\u2019s that will provide information on critical habitat. Key habitat features along the coast of the western Hudson Bay will be analyzed by running generalized linear models based on a grid system. Results will be used to create a map of key summer habitat along the coast and in estuaries. This poster will describe methods and give initial findings on habitat associations. Decreasing ice cover in the Hudson Bay will result in increased shipping traffic and increased beluga predator range. Improving understanding on beluga estuary use and critical habitat areas will assist in management as warming temperatures result in habitat-based risks to the WHB beluga population.", "num_resources": 1, "num_tags": 3, "organization": {"id": "9e21f6b6-d13f-4ba2-a379-fd962f507071", "name": "ceos", "title": "Centre for Earth Observation Science", "type": "organization", "description": "The Centre for Earth Observation Science (CEOS) was established in 1994 with a mandate to research, preserve and communicate knowledge of Earth system processes using the technologies of Earth Observation Science. Research is multidisciplinary and collaborative seeking to understand the complex interrelationships between elements of Earth systems, and how these systems will likely respond to climate change. Although researchers have worked in many regions, the Arctic marine system has always been a unifying focus of activity.\r\n\r\nIn 2012, CEOS, along with the Greenland Climate Research Centre (GCRC, Nuuk, Greenland) and the Arctic Research Centre (ARC, Aarhus, Denmark) established the Arctic Science Partnership, thereby integrating academic and research initiatives.\r\n\r\nAreas of existing research activity are divided among key themes:\r\n\r\nArctic Anthropology/Paleoclimatology: LiDAR scanning and digital site preservation, archaeo-geophysics, permafrost degredation, lithic morphometrics, zooarchaeology, proxy studies, paleodistribution of sea ice, landscape learning, Paleo-Eskimo culture, Thule Inuit culture, ethnographic analogy, traditional knowledge, climate change and northern heritage resource management.\r\n\r\nAtmospheric Studies/Meteorology: Boundary layer, precipitation, clouds, storms and extreme weather, circulation, eddy correlations, polar vortex, climate, teleconnections, geophysical fluid dynamics, flux and energy budgets, ocean-sea ice-atmosphere interface, radiative transfer, ice albedo feedback, cloud radiative forcing, pCO2. \r\n\r\nBiogeochemistry: Organic carbon, greenhouse gases, bubbles, Ikaite, carbonate chemistry, CO2 fluxes, mercury and other trace metals, minerals, hydrocarbons, brine processes, otolith microchemistry, sediments, biomarkers. \r\n\r\nContaminants: Mercury, trace metals, PAHs, source, transport, transformation, pathways, bioaccumulations, marine ecosystems, marine chemistry. \r\nEarth Observation Science: Active and passive microwave, LiDAR, EM induction, spatial-temporal analysis, forward and inverse scattering models, complex permittivity, ocean colour, ocean surface roughness, NIR, TIR, satellite telemetry, GPS. Ice-Associated Biology: Biophysical processes, primary production; ice algae, ice microbiology, bio-optics, under-ice phytoplankton. \r\n\r\nInland Lakes and Waters: Hydrologic connectivity, watershed systems, sediment transport, nutrient transport, contaminants, landscape processes, remote sensing, freshwater-marine coupling. Marine Mammals: Seals, whales, habitat, conservation, satellite telemetry, distribution, population studies, prey behaviour, bioacoustics.\r\n\r\nModelling: Simulation of sea ice and oceanic regional processes, Nucleus for European Modelling of the Ocean (NEMO), ice-ocean modelling and interactions, hind cast simulations and projections for sea ice state and ocean variables based on CMIP5 scenarios and MIROC5 forcing, validation.\r\n\r\nOceanography: Circulation, temperature, in-flow and out-flow shelves, water dynamics, microturbulence, Beaufort Gyre, eddy correlations.\r\n\r\nSea Ice Geophysics:Thermodynamic and dynamic processes, extreme ice features and hazards, snow, ridges, polynyas.\r\n\r\nTraditional and Local Knowledge: Indigenous cultures, Inuit, Inuvialuit, oral history, toponomy, mobility and settlement, hunting, food security, sea ice use, community-based research, community-based monitoring, two ways of knowing.", "image_url": "2021-11-13-003953.952874UMLogoHORZ.jpg", "created": "2017-07-21T13:15:49.935872", "is_organization": true, "approval_status": "approved", "state": "active"}, "owner_org": "9e21f6b6-d13f-4ba2-a379-fd962f507071", "private": false, "related_datasets": [], "related_programs": ["941c8243-8acf-4a9e-af07-ded5acdc35f6"], "rightsIdentifierScheme": "SPDX", "rightsSchemeURI": "https://spdx.org/licenses", "schemeURI": "", "state": "active", "subjectScheme": "", "theme": ["98238b1c-5be8-41ad-8c6e-74cdc4f5f369"], "title": "Beluga Use of Estuary Habitat in the Western Hudson Bay", "type": "publication", "url": null, "version": null, "Author": [{"affiliation": "Centre for Earth Observation Science - University of Manitoba", "creatorName": "Ausen, Emma L", "email": "emma.ausen@umanitoba.ca", "nameIdentifier": "https://orcid.org/0000-0002-9719-1354", "nameIdentifierScheme": "ORCID", "nameType": "Personal", "schemeURI": "http://orcid.org/"}, {"affiliation": "Freshwater Institute - Fisheries and Oceans Canada", "creatorName": "Marcoux, Marianne", "email": "", "nameIdentifier": "", "nameType": "Personal"}, {"affiliation": "Centre for Earth Observation Science - University of Manitoba", "creatorName": "Barber, David", "email": "", "nameIdentifier": "", "nameType": "Personal"}], "awards": [{"awardTitle": "", "awardURI": "", "funderIdentifier": "", "funderIdentifierType": "", "funderName": "", "funderSchemeURI": "", "grantNumber": ""}], "relatedResources": [{"RelatedIdentifier": "", "ResourceTypeGeneral": "", "name": "", "relatedIdentifierType": "", "relationType": "", "resourceType": "Online Resource", "seriesName": ""}], "resources": [{"cache_last_updated": null, "cache_url": null, "created": "2025-09-24T18:00:20.771965", "datastore_active": false, "datastore_contains_all_records_of_source_file": false, "description": "", "format": "PDF", "hash": "", "id": "a7255b00-d643-4513-a7df-5c9f1de78704", "last_modified": "2025-09-24T18:00:20.617412", "metadata_modified": "2025-09-24T18:00:21.162380", "mimetype": "application/pdf", "mimetype_inner": null, "name": "Ausen_Emma_#48.pdf", "package_id": "f1b267d1-ae79-4db5-ae4a-41816488eeff", "position": 0, "resCategory": "data", "resource_type": null, "size": 1334124, "state": "active", "url": "https://canwin-datahub.ad.umanitoba.ca/data/dataset/f1b267d1-ae79-4db5-ae4a-41816488eeff/resource/a7255b00-d643-4513-a7df-5c9f1de78704/download/ausen_emma_48.pdf", "url_type": "upload"}], "tags": [{"display_name": "AERIAL PHOTOGRAPHS", "id": "bafe04c6-e938-4966-a4ab-a8ce5f1b7d04", "name": "AERIAL PHOTOGRAPHS", "state": "active", "vocabulary_id": null}, {"display_name": "Hudson Bay", "id": "e8708f68-d619-4444-8951-96582b048848", "name": "Hudson Bay", "state": "active", "vocabulary_id": null}, {"display_name": "belugas", "id": "c30bbeac-f90d-43b3-9929-4bf6ffea18f2", "name": "belugas", "state": "active", "vocabulary_id": null}], "groups": [], "relationships_as_subject": [], "relationships_as_object": []}}
