NORPERM: The Norwegian TSP Permafrost DatabaseKirsti MidttømmeGeological Survey of Norway, NGUGeir StrandGeological Survey of Norway, NGUHåvard JuliussenDepartment of Geology, The University Centre in Svalbard, NorwayHanne H. ChristiansenDepartment of Geology, The University Centre in Svalbard, NorwayIntroductionAccording to the IPY data policy, all data from IPYprojects should be stored in international data repositories,ensuring long-term preservation and sustained access.Also, the increasing amount of ground temperature data inNorway and Svalbard collected as part of different projectsneeds to be managed and stored centrally in a standardformat database. The Geological Survey of Norway (NGU)is the managing institution for geological data in Norway,and is thus the obvious institution to host the Norwegianground temperature database. A Norwegian permafrostdatabase—NORPERM—is thus being developed at NGU aspart of the IPY project “Permafrost Observatory Project: AContribution to the Thermal State of Permafrost in Norwayand Svalbard (TSP NORWAY)” (Etzelmüller et al. 2008).This database will include temperature data from about40 existing boreholes, hundreds of miniloggers measuringshallow ground temperatures, Bottom Temperature of Snow(BTS) campaigns, and from similar research projects suchas the CRYOLINK project (Etzelmüller et al. submitted).NORPERM will be the important data legacy from the TSPNORWAY project.Data Sources – The TSP NORWAY ProjectThe observatories and data of the TSP NORWAY projectare used as templates for NORPERM. There are two mainpermafrost observatories in TSP NORWAY: Troms innorthern Norway and Nordensköldland in Svalbard (Fig.1). Within the observatories, individual measurement sites(boreholes, miniloggers, etc.) are grouped together at specificso-called permafrost locations (e.g., mountains, valleys,etc.). Temperature data to be included in NORPERM areground temperatures in 10–20 m deep boreholes, shallowground temperatures using miniloggers, and traditionalBTS data. There are 11 TSP boreholes in northern Norwayand around 15 in Svalbard. Data from in situ periglacialprocess monitoring, geodetic surveys and/or remote sensingof landform dynamics, and periglacial landform ages arealso collected in the TSP project and may be included in thedatabase.Extensive datasets on ground temperature exist, mainlyfrom southern Norway, from previous permafrost projectssuch as the PACE project and the Dovrefjell monitoringprogramme (Etzelmüller et al. submitted), and from severalPhD theses.NORPERM – Structure and AccessThe structure of NORPERM is shown in Figure 2.NORPERM is structured with “permafrost location” at thefirst level, corresponding to the locations where measurementsare clustered. Overview information on climate, large-scalegeomorphology, geology, etc., and photos are included at thislevel. At the next level are boreholes, (with either continuoustemperature logging or sporadic manual measurements),Figure 1. Left: the Norwegian part of the North Scandinavian Permafrost Observatory (69–70°N). Right: the Svalbard NordenskioldslandPermafrost Observatory (78°N). Locations of TSP (black dots) and existing (grey dots) boreholes are shown. Based on Google Earth.213

Mapping and modeling thedistribution of permafrost in the Nordic countries.Extended Abstracts of the <strong>Ninth</strong> <strong>International</strong><strong>Conference</strong> on Permafrost, Fairbanks, Alaska, 29June–3 July 2008.Figure 2. Overview of the structure of the NORPERM database.shallow ground temperatures recorded with miniloggers,and BTS datasets. Photographs and summary graphics areincluded for each borehole and minilogger. The boreholeswill also be registered in the national borehole database,which is under construction at NGU. Information andcore samples from more than 6000 boreholes from miningexploration will be available through this service, andpotential boreholes with negative ground temperatures willbe included in NORPERM.Relevant geographic, meteorological, geological, andgeophysical data for the permafrost locations, existing atother institutions and available through Norway Digital(a national public cooperation of digital data betweenNorwegian national institutions), are linked to the NORPERMdatabase. Metadata and data structure for boreholes followthe international standard format, and will be included inthe <strong>International</strong> Global Terrestrial Network of Permafrost(GTN-P), which is the official international database for theinternational TSP IPY project. Data will be quality checkedby TSP project scientists to ensure data quality.NORPERM will be accessible through the websites of TSPNORWAY (www.tspnorway.com) and NGU (www.ngu.no).The dissemination of information is based on technologiesfor Internet distribution established through Norway Digital.Web map service (WMS) data will show the permafrostlocalities on both topographical and geological maps.Downloaded data will be available in standard formats asgraphical plots, tables, pictures or “facts sheets.”Future DevelopmentCurrent map visualization in NORPERM is in 2D.We aim at presenting NORPERM data in 3D in the nearfuture, following guidelines given by a working group onvisualization techniques at NGU. We also plan to presentour results through Google Earth, as other types of IPY dataare.Three boreholes have been equipped with modem. Thus,real-time borehole temperature data will be available throughour webpage (www.tspnorway.com).214
