The core partner data centres that are integrated in NorDataNet are listed in https://www.nordatanet.no/en/node/69. In addition to this NorDataNet harvests information on relevant datasets from a number of other data centres. The data centre responsible for the data presented is usually (but not always) listed in the discovery metadata. In essence NorDataNet is an aggregating service that combines information from a number of existing data centres.
Citation of data and service
If you use data retrieved through this portal, please acknowledge our funding source:
Research Council of Norway, project number 245967/F50, Norwegian Scientific Data Network.
Always remember to cite data when used!
Citation information for individual datasets is often provided in the metadata. However, not all datasets have this information embedded in the discovery metadata. On a general basis a citation of a dataset include the same components as any other citation:
author, title,
year of publication,
publisher (for data this is often the archive where it is housed),
edition or version,
access information (a URL or persistent identifier, e.g. DOI if provided)
All partner repositories of NorDataNet support Digital Object Identifiers (DOI), but not all datasets are minted. Whether or not minted depends often on source of the data (e.g. operational data are often yet not minted). However, all data centres support persistent identifiers according to local systems. The information required to properly cite a dataset is normally provided in the discovery metadata the datasets.
Brief user guide
The Data Access Portal has information in 3 columns. An outline of the content in these columns is provided above. When first entering the search interface, all potential datasets are listed. Datasets are indicated in the map and results tabulation elements which are located in the middle column. The order of results can be modified using the "Sort by" option in the left column. On top of this column is normally relevant guidance information to user presented as collapsible elements.
If the user want to refine the search, this can be done by constraining the bounding box search. This is done in the map - the listing of datasets is automatically updated. Date constraints can be added in the left column. For these to take effect, the user has to push the button marked search. In the left column it is also possible to specific text elements to search for in the datasets. Again pushing the button marked "Search" is necessary for these to take action. Complex search patterns can be constructed using logical operators identified in the drop down menu with and phrases embedded in quotation marks. Prefixing a phrase with '-' negates the phrase (i.e. should not occur in the results). Searches are case insensitive.
Other elements indicated in the left and right columns are facet searches, i.e. these are keywords that are found in the datasets and all datasets that contain these specific keywords in the appropriate metadata elements are listed together. Further refinement can be done using full text, date or bounding box constraints. Individuals, organisations and data centres involved in generating or curating the datasets are listed in the facets in the right column. The combination of search fields (including facets) is based on a logical "AND" combination of the fields, i.e. all conditions are fulfilled for the results provided.

The data set contains information on weather, sea state, sea ice and icebergs recovered from the logbooks, catch books, notebooks and meteorological journals from a number of vessels during their voyages to the Southern Ocean and Antarctica. This work builds on the earlier phase of the project “Historical sea ice data from the Southern Ocean” aimed at recovering climate and sea ice data from Norwegian whaling vessels (Divine et al., 2021). The extended database comprises a collection of 27 documents of various types covering the period of 1932-1940 was keyed and translated. The documents are associated with vessels that was operated by Norwegian whaling companies or British companies with Norwegian crews. Details on data sources, methods used and basic analysis conducted on the data are found in the attached project report file. Note that this is an updated version (V2) of the dataset from November 2023. For more details on the data structure and individual files please see the attached document “Divine_et_al_AntarcticLogs_v2_updateNov2023.pdf”. Data are stored as zip archive in “Divine_et_al_Antarctic_logbooks_documents_CSV_IMMA1_compatible_format_v2_Nov2023.zip” (single file per document) and “Divine_et_al_data_publication_Antarctic_logbooks_v2_Nov2023_final.xlsx” (all data in one xlsx file)
This dataset contains a depth profile of temperature in top 20 m of firn near the summit of Blåskimen Island, Western Dronning Maud Land. The measurements were made using a thermistor string installed into a borehole. The thermistor was left for ~25 hours in the borehole. The data are provided in MATLAB (.mat) file format named ‘IRD_borehole_temp_dat.mat’ with following arrays- • ‘depth’ array with depth data in meters • ‘time’ array with time data in minutes • ‘temp’ matrix with each column containing temperature measurements with depth at a given time in degree Celsius.

Deler av kartdataene er av eldre dato og ikke egnet for navigasjon. Datakvaliteten er angitt på objektnivå i kartdatasettene (SOSI-egenskapene målemetode og nøyaktighet). Høydeangivelse på punkt- og nodenivå er kun angitt i SOSI-filene.
Parts of the map data are of older dates and not suited for navigation. Data quality is indicated on object level in the map datsets (the SOSI attributes “målemetode” (measuring method) and “nøyaktighet” (accuracy). Elevation on point and node level is present only in the SOSI files.
Dette geologiske kartet fra Norsk Polarinstitutt har blitt produsert med tanke på å brukes på smart-telefon, nettbrett eller PC uten nett-tilkobling, for eksempel til feltarbeid eller som et hendig oppslags-kart. Kartet består av 5 raster-filer i GIS-formatet JPEG2000 og er tilgjengelig som nedlasting fra datasenteret til Norsk Polarinstitutt
Informasjon om de geologiske enhetene er plassert som tekst-merkelapper direkte i kartbildet, i motsetning til en vanlig tegnforklaring. Ved å zoome inn på kartet finnes informasjon om geologiske enheter, vist med blå tekst (alder i parentes). I tillegg er hvert enhet (farge) merket med en tilsvarende 4-sifret kode i blå skrift.
I felten kan mobile dingser med GPS vise brukeren sin posisjon på kartet. Avhengig av skjermoppløsning er full detaljgrad i kartet synlig på ca. 1:30 000-skala, men kartet kan også vises på mye større skala for å se f.eks. regionale geologiske trekk.
Kartet kan vises på Android eller iOS-enheter med appen “Geoviewer” fra Extensis (tidligere Lizardtech). På datamaskin fungerer QGIS eller ArcMap bra for å vise kartet. Se forklaring på hvordan overføre kartet til din smart-telefon eller nettbrett lenger nede på sida.
Data
Kartet er laget ved å bruke data fra Norsk Polarinstitutt 1:250 000-skala geologiske kart for Svalbard, opprinnelig publisert i “Geoscience Atlas of Svalbard” av Dallmann (ed.) 2015. Dette kartet er generalisert fra 1:100 000-skala kart-data i hovedkartserien til Norsk Polarinstitutt, og er publisert i Geoscience Atlas of Svalbard (Dallmann 2015).
Til å produsere dette kartet er topografiske data fra S100 (topografi, vann) og S250 (kystlinje)-datasettene fra Norsk Polarinstitutt brukt. Fjellskygge er konstruert med S0 Terrengmodell med 20 meter pr. pixel oppløsning. Bre og snøflekk-områder er vist med datasettet for 2001-2010 av König mfl. (2013), som gir et mer oppdatert bilde av blotning-situasjonen nær breer og snøflekker. Områder der geologiske polygoner ikke er justert til nye blotninger er vist i brunt. Kystlinjen er i noen tilfeller endret for å tilpasses bre-fronter som ender i sjøen.
Forbehold om datakvalitet Dette er et nytt geologisk kartprodukt, og det kan forekomme feil. Spesielt tegnforklaring, som er skrevet direkte på geologiske enheter, kan være problematisk i noen områder. Vi er interessert i tilbakemelding på mulige forbedringer av kartet. Send gjerne tilbakemeldinger på e-post til Geokart@npolar.no.
Dette er et geologisk kart ment for å formidle vitenskapelige data, og er ikke egnet for navigasjon. Noen områder av Svalbard er ennå ikke kartlagt i detalj, og en del av dataene er av eldre dato, så datakvaliteten for dette kartet er varierende. Kartet kan inneholde feil i grunnlagsdata, kartpresentasjon, kartografi og tekst-beskrivelser. For en stor del er geologien kartlagt for en mindre detaljert skala enn den det er mulig å oppnå med dette kartproduktet, så geologiske trekk og enheter vil i ulik grad fremstå feilplassert ved bruk av god GPS-posisjon og detaljert zoom-nivå. Breer og spesielt bre-fronter er i konstant forandring, og selv om ganske oppdaterte data er brukt for å lage kartet, vil det være feil i en del bre-posisjoner. Vær oppmerksom på at det topografiske grunnlaget som er brukt her i mange tilfeller er av nyere dato enn det som opprinnelig var brukt under kartleggingen i felt. Dette kan også føre til feil i kartet.
Geologiske kart-data vil kontinuerlig være gjenstand for re-tolkning og endring. For en full beskrivelse av kartleggingsprogrammet ved Norsk Polarinstitutt, geologiske kart-data presentert her og referanser, se Dallmann (ed.) 2015, eller besøk npolar.no

Abstract This geological map from the Norwegian Polar Institute has been prepared to be used offline on a smartphone, tablet or computer, for example for field work or a handy reference. It consists of 5 raster-files in the JPEG2000 GIS-format, available to download from the Norwegian Polar Institute data centre data.npolar.no via https://data.npolar.no/dataset/eafafbb7-b3df-4c71-a2df-316e80a7992e/.
Information about the geological units has been placed as text labels (in blue typescript) directly on the map, as opposed to a regular legend. By zooming in, information about each geological unit on the map can be found, shown in blue text (age in parentheses). In addition, each unit is labelled with a corresponding 4-digit code also in blue typescript.
In the field, GPS-enabled devices can show the user’s location on the map. Depending on screen resolution, full detail of the map (including text labels) is best viewed at ca. 1:30 000 scale, but the map can also be viewed at much larger scales to see e.g. regional geological features.
For mobile use, the app “Geoviewer” from Extensis (formerly Lizardtech) can be used. On a computer, QGIS works well to view these maps. See an explanation below on how to transfer the map to your tablet or smartphone.
Data
The map is made using data from the Norwegian Polar Institute 1:250 000-scale geological map for Svalbard, originally published in Dallmann (ed.) 2015. This geological map has been generalised from the 1:100 000-scale main map series published by the Norwegian Polar Institute, and is published in Geoscience Atlas of Svalbard (Dallmann 2015).
For the purpose of this map product, topographic data from the Norwegian Polar Institute S100 Map (topography, water) and S250 (coastline) data sets have been used. Hill shade was created using the NPI S0 Terrengmodell at 20 meters/pixel resolution. Glacier and snow patch outlines are shown using the 2001-2010 dataset of glacier area outlines for Svalbard by König et al. (2013), which gives a more up to date picture of the outcrop situation near glaciers or snow patches. Areas where geology polygons have not been re-adjusted to the new outcrops are shown in brown. The coast line-data has been adjusted in some cases to adapt to glacier fronts ending in the sea.
Disclaimer This is a new geological map product, and errors may occur. In particular the legend, which have been printed directly on the geological units, can be problematic in places. We appreciate feedback on the map that can be used to improve the map in future versions. Please email feedback to Geokart@npolar.no.
This is a geological map meant to convey scientific data, and is not suited for navigation. This map product may contain errors in base data, map presentation, cartography and text descriptions. Much of the geology was originally mapped for a less detailed scale than what is possible to obtain with this map, so geological features will to varying degrees appear out-of place when a good GPS-position and detailed zoom level is used. Glaciers and in particular glaciers fronts are dynamic features, and although using fairly up-to-date data, this map does contain errors in glacier front positions. Note that the topographic base data used here in many cases is of a newer vintage than the data originally used for geological mapping in the field. This may cause some errors in the map. Some areas of Svalbard have not yet been mapped in detail and some of the data are of older origin, so the data quality presented on this map is variable.
Geological map data will be subject to continual re-interpretation and editing. For a full description of the bedrock mapping programme at the Norwegian Polar Institute, the geological map data presented here and references, see Dallmann (ed.) 2015.
How to transfer the map to mobile devices

This is a bedrock geological map of Jan Mayen distributed as vector files, a georeferenced raster and a related non-spatial lithostratigraphy table.
The map was compiled by W.K. Dallmann and published in Gabrielsen et al. (1997). A version was also published in Dallmann (2014), and the geology of this current edition is equivalent to that publication. The compilation was based on Imsland (1978), Roberts and Hawkins (1965) and Siggerud (1972, 1986)

The mass balance of a glacier is the difference between accumulation in winter and ablation in summer, and is thus a measure of whether the glacier as a whole is increasing or shrinking. It is interesting to monitor mass balance because melting of glaciers can contribute to sea-level rise. Glaciers also influence the local climate and the conditions for fauna and flora in Svalbard. The mass balance is primarily dependent upon the precipitation in winter and the temperature in summer. The height above the sea is also important.
The monitoring of the mass balance of four glaciers and glacier complexes is reported here: Austre Brøggerbreen (since 1967), Midtre Lovénbreen (since 1968), Kongsvegen (since 1987) and Kronebreen/Holtedalsfonna (since 2002). All these glaciers are located near Ny-Ålesund on Vest-Spitsbergen.
3 MHz Deep Radar Measurements along the route of the Norwegian – U.S. Scientific Traverse of East Antarctica 2008-2009. The primary goal of the deep radar was to measure ice thickness along the traverse route. In conjunction with surface elevation, the data also gives topography at the base of the ice sheet. Other useful aspects of the data are the clear internal layers and the ability to assess the presence or absence of water at the base of the ice sheet.

Instruments
The pulse was generated by a Kentech GPR pulser emitting +/- 2kV at a PRF of 500-1000 Hz. At the receive end the signal was fed through a minicircuits RF Transformer 9:1 (16:1 was also tried), followed by an amplifier and into a picoscope dual channel digital oscilloscope. The oscilloscope was connected to a CF19 Panasonic toughbook for real time data viewing and data storage. Gecko, a program written and compiled by Rickard Pettersson was used to digitize, display and store the data. A Garmin handheld GPS was connected to the pc and gave position information for each trace. 12V, 55Ah gel cell batteries provided power to both the receive and the transmit electronics.
