AbstractThe Canadian Arctic is currently the focus of increased mapping activities, which aim to provide better knowledge to assist in making informed decisions for sustainable minerals and energy development and land-use management. One of the maps that is needed is a surficial materials map. This paper presents preliminary results of a surficial materials mapping research activity within the Tehery-Wager geoscience mapping activity for the Rae project area of Natural Resources Canada's Geo-mapping for Energy and Minerals program, a collaborative project co-led by the Geological Survey of Canada and the Canada-Nunavut Geoscience Office. The study area is located south of Wager Bay in Nunavut (NTS map areas 46D, E, 56A, H) and covers targeted areas that have not been mapped or mapped only at a reconnaissance scale. A preliminary surficial materials map with 15 classes was produced from a combination of images from RADARSAT-2 in the C-band (with horizontal-horizontal polarization and horizontal-vertical polarization) and from Landsat 8 Operational Land Imager with a digital elevation model and slope data. This paper also presents field observations that were made in the summer of 2015 and will be used as ground control points to validate the map.
Summary(Plain Language Summary, not published)
This report presents preliminary results of a surficial earth materials mapping research project completed along the northwestern shores of Hudson Bay, mainland Nunavut, as part of the surficial geology component of the GEM 2 Tehery-Wager Activity within the Rae Project area. The report outlines the method to produce a preliminary map with 15 surficial materials classes from a combination of remote satellite data and presents field observations that have been acquired in the summer of 2015 and that will be used to validate the map. The findings will support informed decision making for resource exploration and development, and for land use management.
