Ground ice map of Canada

Ground ice map of Canada The mapping depicts a first-order estimate of the combined volumetric percentage of excess ice in the top 5 m of permafrost from segregated, wedge, and relict ice. The estimates for the three ice types are based on modelling by O'Neill et al. (2019) (https://doi.org/10.5194/tc-13-753-2019), and informed by available published values of ground ice content and expert knowledge. The mapping offers an improved depiction of ground ice in Canada at a broad scale, incorporating current knowledge on the associations between geological and environmental conditions and ground ice type and abundance. It provides a foundation for hypothesis testing related to broad-scale controls on ground ice formation, preservation, and melt. 2021-05-19 Natural Resources Canada nrcan.gsc-geosciencedata-donneesgeoscience-cgc.rncan@canada.ca Form DescriptorsNature and EnvironmentScience and TechnologyGround icesegregated icewedge icerelict icePermafrost Ground ice map of CanadaHTML https://doi.org/10.4095/326885 Carte de la glace de sol du CanadaHTML https://doi.org/10.4095/326885 Ground ice map of Canada - ground ice map of Canada layer - EnglishWMS https://wms.geosciences.ca/pin?REQUEST=GetCapabilities&VERSION=1.3.0&SERVICE=WMS&layers=Ground_ice_abundance&legend_format=image/png&feature_info_type=text/html Ground ice map of Canada - ground ice map of Canada layer - FrenchWMS https://wms.geosciences.ca/pin_fr?REQUEST=GetCapabilities&VERSION=1.3.0&SERVICE=WMS&layers=Ground_ice_abundance&legend_format=image/png&feature_info_type=text/html Ground ice map of Canada - WMS service - FrenchWMS https://wms.geosciences.ca/pin_fr?REQUEST=GetCapabilities&VERSION=1.3.0&SERVICE=WMS Ground ice map of Canada - WMS service - EnglishWMS https://wms.geosciences.ca/pin?REQUEST=GetCapabilities&VERSION=1.3.0&SERVICE=WMS
