Arctic Portal

In April 2014, the new Global Terrestrial Network for Permafrost (GTN-P) website has been launched along with its web-based Data Management System (DMS) - & They are hosted at Arctic Portal, Akureyri, north Iceland, and designed in collaboration with the Arctic Portal team, the GTN-P, the International Permafrost Association (IPA) and within the framework of the Changing Permafrost in the Arctic and its Global Effect on 21st Century (Page21) European 7th Framework project and its partners. The GTN-P DMS offers a standardized repository for permafrost temperature and active layer thawing thickness metadata and times series. Researchers can create, upload, edit, visualize and download standardized datasets, metadata forms, charts and statistics. Tools are further developed to provide data processing, analysis capabilities and data quality control and assurance. The end of the distribution chain delivers, for the first time, highly structured global datasets for permafrost temperature and active layer thawing thickness in NetCDF files, format developed by UNIDATA and used by climate modellers. The horizon of the Page21 project is November 2015 but local funding are sought in order to secure the future of the GTN-P DMS and a full position for data manager of this global network in Iceland.

4 boreholes for Iceland are recorded into the GTN-P database and under the responsibility of Bernd Etzelmuller from the University of Oslo - Hagöngur, Gagnheidi, Saudafell near Snæfell, Vopnafjörður mountains. At present the boreholes have loggers only close to the surface and at the bottom. A plan for installing good loggers is waiting the opportunity of a new funding. However discussions are made in order to include the Icelandic permafrost temperature time series to the GTN-P DMS and to the global dataset in NetCDF. (

Þorsteinn Sæmundsson, Jon Kristinn Helgason and Halldór G. Pétursson are carrying researches about the decline of mountain permafrost and the occurrence of recent large debris slides mainly in the Tröllaskagi peninsula in central north Iceland. Recent studies of widespread palsas in the Þjórsárver region, south of Hofjökull and in the Orravatnsrústir region, north of Hofjökull in central Iceland give clear indications of decreasing of premafrost during the last decade. They presented their research at the EGU General Assembly 2014. (
