The ice charts are created through the manual analysis of in situ, satellite, and aerial reconnaissance data. The ice charts have information on ice concentration, stage of development, and ice form, following World Meteorological Organization terminology. This digital record of sea ice charts begins in 2006 and covers the following regions of the Canadian Arctic: Northern Canadian waters (Western Arctic, Eastern Arctic, and Hudson Bay) and Southern Canadian waters (Great Lakes and East Coast). Each regional shapefile (.shp) (encoded in SIGRID-3 format) and associated metadata file (.xml) are combined into a tar archive file (.tar) for distribution.<br/><br/>\nPlease note that the latest SIGRID-3 charts are available for operational or tactical users directly from CIS at https://ice-glaces.ec.gc.ca/prods/sigrids/.", "distribution": [{"@type": "dcat:Distribution", "conformsTo": "http://www.isotc211.org/2005/gmi", "description": "The metadata's original source.", "downloadURL": "https://cmr.earthdata.nasa.gov/search/concepts/C1386246266-NSIDCV0.iso19115", "format": "ISO", "mediaType": "text/xml", "title": "Original Metadata"}, {"@type": "dcat:Distribution", "downloadURL": "https://doi.org/10.7265/N51V5BW9", "format": "HTML", "mediaType": "text/html"}, {"@type": "dcat:Distribution", "downloadURL": "https://dx.doi.org/10.7265/N51V5BW9", "format": "HTML", "mediaType": "text/html"}, {"@type": "dcat:Distribution", "downloadURL": "https://noaadata.apps.nsidc.org/NOAA/G02171/", "format": "BIN", "mediaType": "application/octet-stream"}], "identifier": "10.7265/N51V5BW9", "keyword": ["earth-science-sea-ice-cryosphere-sea-ice-concentration"], "license": "https://www.usa.gov/government-works", "modified": "2026-08-11", "programCode": ["026:000"], "publisher": {"@type": "org:Organization", "name": "NSIDC"}, "spatial": "[\"CARTESIAN\", [{\"WestBoundingCoordinate\": -164.05002, \"NorthBoundingCoordinate\": 83.19372, \"EastBoundingCoordinate\": 21.96925, \"SouthBoundingCoordinate\": 39.52777}]]", "temporal": "2006-01-01/2026-08-03", "theme": ["Earth Science"], "title": "Canadian Ice Service Arctic Regional Sea Ice Charts in SIGRID-3 Format, Version 1"}
