The Yukon is underlain by a great variety of rock types ranging in age from Early Proterozoic to Recent. The various rock types are characterized by different magnetic intensity and this map shows those variations at the regional scale, with highly magnetic rocks represented by warm colours and non-magnetic rocks shown in cool colours. The Residual Total Field magnetic map shows a measure of the total magnetic intensity in the Earth's crust. This magnetic compilation was extracted from the compilation of Oneschuk et al. (2019). The data was gridded at 50 m. Magnetic data for Yukon can be obtained from: http://gdrdap.agg.nrcan.gc.ca/ Distributed from GeoYukon by the Government of Yukon .

The Geological Survey of Canada (Atlantic and Pacific) has collected marine survey field records on marine expeditions for over 50 years. This release makes available the results of an ongoing effort to scan and convert our inventory of analog marine survey field records (seismic, sidescan and sounder) to digital format. These records were scanned at 300 dpi and converted into JPEG2000 format. Typically, each of these files was between 1 to 2 gbyte in size before compression and compressed by a factor of 10:1. Empirical tests with a number of data sets suggest that there is minimal visual distortion of the scanned data at this level of compression. In this KML file, scanned data are available in a reduced-scale thumbnail format and a compressed full-resolution JPEG2000 format.

The Yukon is underlain by a great variety of rock types ranging in age from Early Proterozoic to Recent. The various rock types are characterized by different densities and this map show those variations at the regional scale, with dense rocks represented by warm colours and lighter rocks shown in cool colours. This Bouguer gravity map was compiled by Nathan Hayward, Geological Survey of Canada. Data used in this Bouguer gravity compilation, gridded at 2 km, are from ground-based, regional (~10 km station spacing) gravity surveys acquired by the Geological Survey of Canada and high-resolution (~2 km station spacing) surveys acquired for the Yukon Geological Survey. All surveys are reduced to a Bouguer density of 2670 kg/m3 and statically levelled to the regional data. Corresponding regional gridded data can be downloaded, at no charge, from Natural Resources Canada's Geoscience Data Repository for Gravity Data at http://gdrdap.agg.nrcan.gc.ca/ . High-resolution gravity data can be downloaded from the Yukon Geological Survey at https://data.geology.gov.yk.ca/ Distributed from GeoYukon by the Government of Yukon .

The Yukon is underlain by a great variety of rock types ranging in age from Early Proterozoic to Recent. The various rock types are characterized by different magnetic intensity and this map show those variations at the regional scale, with highly magnetic rocks represented by warm colours and non-magnetic rocks shown in cool colours. The First Vertical Derivative magnetic map highlights the magnetic intensity of near-surface features in the Earth's crust.

The WMS MSSP-EEZ (INSPIRE) represents marine seismic survey profiles for the German EEZ. During the period from 1996 to 2007 five cruises operated by BGR acquired seismic lines from the German EEZ. The aim of these cruises was a detailed survey of the geological structure of the seabed from the North Sea and Baltic Sea. According to the Data Specification on Geology (D2.8.II.4_v3.0, subtopic Geophysics) the content of the information with respect to the seismic profiles is INSPIRE-compliant. The WMS MSSP-EEZ (INSPIRE) contains for each cruise one layer, e.g. GE.seismicLine.pq2. The expeditions are displayed correspondingly to the INSPIRE portrayal rules. Via the getFeatureInfo request the user obtains the content of the INSPIRE attributes platformType und profileType. Additionally, the WMS contains a campaign layer (GE.2DSeismicSurvey) with the INSPIRE attributes campaignType and surveyType.

This digital product is a compilation of surficial geological data of the Halifax Metropolitan area which was defined by Dan Utting using a LiDAR derived bare-earth hillshade model. The LiDAR data was collected by PHB Lasermap, and provided by Halifax Regional Municipality. The data was used to create Open File Maps OFM ME 2011-001 to 2011-012, compiled by D. J. Utting, 2011. The digital product was created by Geoscience and Mines Branch staff at the Department of Energy and Mines. The digital product contains layers for geological features such as: age dates, drumlins, eskers, geological contacts, surficial geologic units, ice movement, moraines, meltwater, neatline, station locations, and large aggregate quarries.
