The Yukon Geological Survey (YGS) has compiled available geotechnical and ground temperature data and related literature from government, industry and other contributors into the Yukon Permafrost Database. This paper reviews the database development process and structure, provides a snapshot of the primary datasets that have been loaded to date and discusses some of its limitations. The database is publicly accessible from an online portal (https://yukon.ca/en/yukonpermafrost) where data may be explored interactively in web maps, tables, and time series and ground temperature envelope graphics. Database contents are also available for download in a variety of formats. The Yukon Permafrost Database provides easily accessible data on permafrost distribution and thermal regime to support the assessment of thaw-related hazard and risk, and works towards the integration of disparate permafrost data at a territorial scale. The database will be maintained and updated regularly and YGS welcomes data contributions from government, industry and academic researchers to facilitate ongoing improvements to our collective knowledge of permafrost in Yukon.

The Yukon Geological Survey has compiled a collection of papers, theses, reports and maps that describe permafrost in the Yukon. These reports have been footprinted and indexed to make them easier to find spatially. Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .

Up to six years of data have been collected at seven stations within Yukon Geological Survey’s permafrost monitoring network between 2008 and 2013. Warm permafrost conditions (>-0.5°C) governed by latent heat effects exist at the Whitehorse, Watson Lake, Ross River School and Dawson School monitoring stations, while average permafrost temperatures in Faro are only marginally cooler at -0.6°C. Mean annual ground temperatures at the Beaver Creek and the Dawson dump forest monitoring stations are much colder at -2.9 and -2.0°C respectively. Most sites show either insignificant or very slight short term permafrost warming trends, although slight cooling is apparent at Ross River School, and rapid warming has occurred at Beaver Creek over the monitoring period. Opportunities to expand the network and collaborate with external parties operating similar monitoring stations should be further explored to facilitate more complete and representative reporting on the thermal state of permafrost in Yukon.

This dataset includes observations of the permafrost temperatures in the Inner Tien Shan were started in 1986 by Kazakhstan Alpine Permafrost Laboratory. Observations are carried out on more than 40 boreholes, at altitudes between 3300-4200 m. The depths of the boreholes vary from 30 to 600 m. The boreholes are located in both loose (moraines) sediments and bedrock. Several boreholes are situated in the territory of the 'Kumtor' goldmine. The geocryological conditions of goldmine 'Kumtor' and nearby territory have been discussed in scientific reports 1988, 1989 and articles (see references). Two boreholes were drilled in body of glacier 'Davydov' and located in the central and lateral parts of the glacier (depth - 30 m). A third borehole passed through the glacier, moraine and bedrock to a depth of 600 m. In the Kumtor and Taragai valleys, permafrost temperature in 14 boreholes from 25 to 50 m depth, between 3300-3750 m ASL were observed. The distance between outermost boreholes is about 40 km. Temperature measurements in 9 geological prospecting adits [tunnels] (lengthwise 1500-1900 m) located in the four neighboring valleys (altitudes from 3920 to 4010 m) were carried out. At the same sites, but in natural conditions, the thermal conductivity of the bedrock was determined by the cylindrical sounding method. Grain size, soil moisture content, cryogenic structure and depth of seasonal thaw were also obtained from 15 pits located in differing altitudinal levels and exposures. At two further sites, ground temperatures measurements at depths of 0, 2, 5, 10, 15, 20 and 40 cm were taken every hour during daylight hours every 5 days over a two year period. Air temperature, wind velocity and duration of daylight were measured at the same time as the ground temperature measurements. These data are presented on the CAPS Version 1.0 CD-ROM, June 1998.

These data consist of fully processed permafrost temperature data from borehole logs acquired by the U.S. Geological Survey (USGS) from the 24-element US Department of the Interior (DOI) Global Terrestrial Network for Permafrost (GTN-P) Deep Borehole Array in arctic Alaska beginning in 1973 and ending in 2014. The data represent the true temperatures in the wellbores and surrounding rocks at the time of the measurements.
