Summary
The Global Terrestrial Network for Permafrost (GTN-P) was established in 1999
by the International Permafrost Association to provide long-term field
observations of active layer and permafrost thermal state that are required to
determine the present permafrost conditions and to detect changes in permafrost
stability. The GTN-P ... contributes to the World Meteorological Organization's
Global Climate Observing System and Global Terrestrial Observing System. The
network to date consists of about 100 active layer monitoring sites that
contribute to the Circumpolar Active Layer Monitoring Program (CALM) and over
300 candidate boreholes for permafrost thermal monitoring. Details of CALM can
be found in the CALM entry on the CAPS CD. The majority of the boreholes for
the thermal monitoring component are between 10 and 125 m deep and are in the
northern hemisphere although a few sites are located in Antarctica and
Argentina. Metadata have been compiled for about 60% of the boreholes and is
included on the CAPS CD and the GTN-P web site (http://www.gtnp.org/), which
will be updated as metadata are compiled. Summary historical data are also
being compiled and will be available along with data submitted on an annual
basis on the GTN-P web site which is hosted by the Geological Survey of Canada.
