This map of the first vertical derivative of the magnetic field was derived from data acquired during an aeromagnetic survey carried out by Fugro Airborne Surveys during the period April 17, 2006 to August 26, 2007. The data were recorded using a split-beam cesium vapour magnetometer (sensitivity = 0.005 nT) mounted in the tail boom of a Cessna Caravan aircraft. The nominal traverse and control line spacings were, respectively, 800 m and 2 600 m, and the aircraft flew at a nominal terrain clearance of 250 m. Traverse lines were oriented N30degreesE with orthogonal control lines. The flight path was recovered following post-flight differential corrections to the raw Global Positioning System data and inspection of ground images recorded by a vertically-mounted video camera.

This dataset consists of a set of polygons that represent the drainage areas of active discharge stations within the Arctic Drainage Area. In partnership with the provinces, territories and other agencies, the Water Survey of Canada (WSC) operates a network of over 2600 active hydrometric gauges across the country. The NHS Basin Polygon dataset is compilation of datasets collected from a number of contributing agencies, including provinces, territories and other government departments. Environment and Climate Change Canada staff in a number of offices across the country is also responsible for the derivation of large parts of the dataset.

All available bathymetry and related information for Chestermere Lake were collected and hard copy maps digitized where necessary. The data were validated against more recent data (Shuttle Radar Topography Mission 'SRTM' imagery and Indian Remote Sensing 'IRS' imagery) and corrected where necessary. The published data set contains the lake bathymetry formatted as an Arc ascii grid. Bathymetric contours and the boundary polygon are available as shapefiles.

An archive of 2D regional seismic and long period magnetotelluric data collected during 20 years of work under the LITHOPROBE project. Data are primarily onshore and cover widespread regions of Canada. Available data types include raw digital data, processed sections, and images of final sections, as well as auxiliary information required for analysis of the data.

This table is part of a series of tables that present a portrait of Canada based on the various census topics. The tables range in complexity and levels of geography. Content varies from a simple overview of the country to complex cross-tabulations; the tables may also cover several censuses.

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. These indicators present the concentrations of 4 substances (mercury, lead, cadmium and bisphenol A) in Canadians for the periods 2007 to 2009, 2009 to 2011, 2012 to 2013, and 2014 to 2015. Chemical substances are everywhere, including in the air, soil, water, products and food, and can enter the body through ingestion, inhalation and skin contact. Through biomonitoring, the government can identify priorities, develop or revise risk management strategies, and track progress on policies put in place to reduce or control these substances.
