The Geoscience Data Repository (GDR), is a collection of Earth Sciences Sector geoscience databases that is managed and accessed by a series of Information Services (GDRIS). This site allows for you to discover, view and download, free of charge, the following information using these services:

• MIRAGE - Geoscience map images

  The GSC has published thousands of maps since the mid-1800's. More than 10,000 of these maps have been scanned and are available through the MIRAGE site.

• Digital geoscience maps

  The Geological Survey of Canada has published about 400 maps digitally. The geological polygons for approximately 250 of these maps are currently being made available to find, preview, and download as shape files through this map search tool.

• Aeromagnetic and Electromagnetic data

  Aeromagnetic Data: Compilation grids (200m and 1000m) of Canada: residual total magnetic field and first vertical derivative of the magnetic field. Point and grid data for 575+ individual surveys. Electromagnetic Data: Point and grid data for 150+ individual surveys.

• Borehole Geophysical Data

  Borehole logs of various geophysical properties including natural gamma, spectral gamma-gamma, acoustic velocity, P & S wave velocity, electrical methods, inductive conductivity, three-component magnetics, magnetic susceptibility and temperature. Also corresponding images of logs and geology.

• Gravity data

  Compilation grids (2000 m) of Canada: Bouguer, Free-air, horizontal gradient, first vertical derivative, isostatic, and observed gravity data. Point data from the Canadian Gravity Database.

• Radioactivity data

  Compilation grids (250 m) of Canada: Potassium (K), Uranium (eU), Thorium (eTh), Natural air absorbed dose rate, eU/K, eTh/K, and eU/eTh data from the NATGAM database. Point and grid data for 300+ individual surveys.

• Seismic and magnetotelluric data

  Seismic and magnetotelluric data from various projects including Lithoprobe, the Frontier Geoscience Program, and the Laurentian Basin Seismic Survey, as well as the East Coast and Arctic Refraction Catalogues.

• NGR geochemical data

  Geochemical point data (lake sediment, stream sediment, lake water, stream water) from the National Geochemical Reconnaissance database

• Geochemical survey metadata

  Searchable metadata for over 500 geochemical surveys conducted across Canada since the 1950s.

• Mineral deposits

  World Mineral Deposit Database and a Canadian Mineral Deposit Synthesis that describes important mineral deposit classes in Canada.

• BASIN

  BASIN contains a wealth of geological, geophysical and engineering information related to many years of petroleum exploration, primarily offshore northern and eastern Canada.

• Energy - Fossil Fuels data discovery tool

  Data related to fossil fuels (oil, gas, coal) in Canada; Canadian National Coal inventory; analysis of borehole cuttings, core and outcrop samples, gasoline fraction, saturates, aromatics, hydrocarbon, geothermal observations.

• Canadian geochronology knowledge base

  The compilation represents publicly available reports of geochronological information for Canada

• Physical Rock Properties

  The National Rock Properties Database is comprised of data collected from borehole geophysical logs, measurement of core samples and rock samples

• Expedition Database

  Expedition Database (ED) contains information (metadata) and data related to the scientific cruises conducted by or on behalf of GSC Atlantic and Pacific.

• Physical Archive Database

  Offshore and coastal Canadian samples and geophysical records holdings

• Canadian Marine Multibeam Bathymetric Images

  The Geological Survey of Canada has compiled various datasets of high resolution marine multibeam bathymetry, comprising survey data collected by Natural Resources Canada and other partners over the last 10 years.

• Canadian Marine Geoscience Map Vectors Web Mapping Service

  The Geological Survey of Canada (GSC) has produced maps depicting up-to-date geoscience knowledge and attributes of the Canadian terrestrial landmass and offshore territories.

• Coastal Monitoring Data, Arctic and Eastern Canada and Selected Lakes

  Sites in Canada where repetitive surveys, photographs, sediment samples and thaw depth measurements (in permafrost regions) document shoreline characteristics and rates of change.

• Lexicon of Canadian Geological Names (CGKN)

  Database of over 12,000 geological (lithological and chronological) names used in Canada.
