Despite its unusual dirty appearance, its role in the formation of deep water and the risk it presents along a proposed year-round shipping route, this ice pack remains relatively unstudied. Here, we use modern spaceborne observations and results from a high-resolution ice-ocean model to characterize the ice pack and examine the processes that lead to its extreme thickness and unique discoloration. We first identify a persistent polynya in southeastern Foxe Basin that is a key site for ice production. Using a newly developed approach to process ICESat-2 altimetry data we provide improved observations of total (snow+ice) freeboards, which reach up to 60 cm in central and eastern Foxe Basin. Using coastal observations of snow depth, we estimate an ice freeboard of 35 cm, which corresponds to an ice thickness of around 3m. This is quite thick for a seasonal ice cover at this latitude, highlighting the role of tidal dynamics in thickening the ice in Foxe Basin. Tides also lead to dirty appearance of the ice as they resuspend sediment from the shallow seafloor and lead to new ice growth within the heavily fractured ice pack. Overall, we provide the first in-depth view of the formation, growth and melt of a thick, dirty ice pack in Foxe Basin and comment on its role in both deep water formation and risk posed to potential shipping operations in the area.", "num_resources": 1, "num_tags": 5, "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": [], "rightsIdentifier": "CC-BY-4.0", "rightsIdentifierScheme": "SPDX", "rightsSchemeURI": "https://spdx.org/licenses", "rightsURI": "https://spdx.org/licenses/CC-BY-4.0.html", "schemeURI": "", "state": "active", "subjectScheme": "Polar Data Catalogue", "theme": ["3707ff10-6424-4858-9ec9-7d67b38831b3"], "title": "The Sea Ice Cover in Foxe Basin: A Thick, Deformed, Dirty, Seasonal Ice Cover Along a Proposed Arctic Shipping Route", "type": "publication", "url": null, "version": null, "Author": [{"affiliation": "Centre for Earth Observation Science - University of Manitoba", "creatorName": "Babb, David", "email": "david.babb@umanitoba.ca", "nameIdentifier": "0000-0002-7427-8094", "nameIdentifierScheme": "ORCID", "nameType": "Personal", "schemeURI": "http://orcid.org/"}, {"affiliation": "Centre for Earth Observation Science - University of Manitoba", "creatorName": "Kirillov, Sergei", "email": "sergei.kirillov@umanitoba.ca", "nameIdentifier": "0000-0002-9636-7952", "nameIdentifierScheme": "ORCID", "nameType": "Personal", "schemeURI": "http://orcid.org/"}, {"affiliation": "Centre for Earth Observation Science - University of Manitoba", "creatorName": "Ehn, Jens", "email": "jens.ehn@umanitoba.ca", "nameIdentifier": "0000-0002-8885-7441", "nameIdentifierScheme": "ORCID", "nameType": "Personal", "schemeURI": "http://orcid.org/"}], "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": "2024-12-19T15:48:27.795588", "datastore_active": false, "datastore_contains_all_records_of_source_file": false, "description": "The Sea Ice Cover in Foxe Basin: A Thick, Deformed, Dirty, Seasonal Ice Cover Along a Proposed Arctic Shipping Route", "format": "PDF", "hash": "", "id": "6b6c5d53-e1b7-4dec-b479-b137520d651f", "last_modified": "2024-12-19T15:48:27.718833", "metadata_modified": "2024-12-19T15:48:28.115854", "mimetype": "application/pdf", "mimetype_inner": null, "name": "ArcticNet 2024 Poster", "package_id": "b339a401-4abc-4d88-920e-fd38c2907ba3", "position": 0, "resCategory": "documents", "resource_type": null, "size": 4103265, "state": "active", "url": "https://canwin-datahub.ad.umanitoba.ca/data/dataset/b339a401-4abc-4d88-920e-fd38c2907ba3/resource/6b6c5d53-e1b7-4dec-b479-b137520d651f/download/ac2024_foxebasin_v4_david_b.pdf", "url_type": "upload"}], "tags": [{"display_name": "Arctic Shipping", "id": "f7448173-8307-4599-b46e-c9f4fb192630", "name": "Arctic Shipping", "state": "active", "vocabulary_id": null}, {"display_name": "Remote Sensing", "id": "817ba4e3-855c-48e4-b503-58e3d5cf6302", "name": "Remote Sensing", "state": "active", "vocabulary_id": null}, {"display_name": "Sea Ice", "id": "5ff38099-75ca-4472-bb8f-4d03a3a76239", "name": "Sea Ice", "state": "active", "vocabulary_id": null}, {"display_name": "Sea ice dynamics", "id": "eb5116fd-9249-4d2e-b76b-920fa54d1696", "name": "Sea ice dynamics", "state": "active", "vocabulary_id": null}, {"display_name": "sea ice thickness", "id": "dad48ed7-cba3-4ae3-9fff-7a7d3fa5c5da", "name": "sea ice thickness", "state": "active", "vocabulary_id": null}], "groups": [], "relationships_as_subject": [], "relationships_as_object": []}}
