    The dataset contains projects that are currently, or have been, subject to environmental assessment review. Attributes include the status of the review, descriptions of the project, the project type, project contact information, and documented related to the project. This layer consists of points themed two ways a. Project Status - This theme consists of four layers that reflect the potential status of a given EA review process - pre-application, application review, completed, and withdrawn. b. Project Sector - This theme consists of eight layers that reflect the potential sectors of projects under review - Transportation, Mining, Energy, Water, Waste, Tourism and Recreation, Industrial, and Other

    Yukon Geological Survey re-analyzed stream sediment sample pulps from GSC's archives in Ottawa. As a next step to improving the dataset, two of the areas covered by the recently-released Open Files were selected for further data processing to add value to the raw data. Catchment areas were delineated for each sample, and data were modeled to isolate the geochemical signatures that are characteristic of the known mineral deposit types in the area. This report and the accompanying series of maps present the results of this ?value-added? analysis of raw stream sediment geochemical data. The project was funded by the Canadian Northern Economic Development Agency (CanNor) through their Strategic Investments in Northern Economic Development program.

    GeoFIELD is a data management system that is designed to facilitate practical data entry and the production of geologic maps while in the field. GeoFIELD writes data to a Microsoft Access 2000 database and allows digitizing and plotting of station locations and structural data in an AutoCAD Map 2000 drawing using a Visual Basic for Applications interface. GeoFIELD provides a user-friendly interface within a familiar Windows environment. Its extensive picklists are easily customizable and ensure consistency and quality control during data entry. The widespread availability and easy customization features of Microsoft Access make GeoFIELD a flexible application that can be adapted to varying needs. In addition, Microsoft Access provides the ability to easily build complex database queries and generate reports. GeoFIELD can also be used successfully with a handheld device as well as with common GIS applications such as ArcGIS 8.x.

    This map of the residual total magnetic field was derived from data acquired during an aeromagnetic survey carried out by Goldak Airborne Surveys during the period May 16, 2009 to July 1, 2009. The data were recorded using a split-beam cesium vapour magnetometer mounted in the tail boom of a Piper Navajo aircraft. The nominal traverse and control line spacings were 400 m and 2400 m, respectively, and the aircraft flew at a nominal terrain clearance of 150 m.

    This map of the residual total magnetic field was derived from data acquired during a helicopter-borne aeromagnetic survey carried out by Fugro Airborne Surveys during the period between February 4 to March 15, 2010. The data were recorded using split-beam cesium vapour magnetometers (sensitivity = 0.005 nT) rigidly mounted on each of the two Astar 350B aircraft (C-FGSC and C-GAVO). The nominal traverse and control line spacings were, respectively, 400 m and 2 400 m, and the aircraft flew at a nominal terrain clearance of 100 m. Traverse lines were oriented N30?E 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. The survey was flown on a pre-determined flight surface to minimize differences in magnetic values at the intersections of control and traverse lines.

    This map of the first vertical derivative of the total magnetic field was derived from data acquired during a helicopter-borne aeromagnetic survey carried out by Fugro Airborne Surveys during the period between February 4 to March 15, 2010. The data were recorded using split-beam cesium vapour magnetometers (sensitivity = 0.005 nT) rigidly mounted on each of the two Astar 350B aircraft (C-FGSC and C-GAVO). The nominal traverse and control line spacings were, respectively, 400 m and 2 400 m, and the aircraft flew at a nominal terrain clearance of 100 m. Traverse lines were oriented N30?E with orthogonal control lines. The flight path was recovered following post-flight differential corrections to the raw Global Positioning System (GPS) data and inspection of ground images recorded by a vertically-mounted video camera. The survey was flown on a pre-determined flight surface to minimize differences in magnetic values at the intersections of control and traverse lines.
