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.

Abstract:
Quality controlled timeseries from Norwegian weather station 0-578-0-99720. Data are climate consistent following a number of automated and manual quality control routines.
The archipelago of Svalbard presently contains approximately 33,200 km2 of glaciers, with a large number of small valley glaciers as well as large areas of contiguous ice fields and ice caps. While a first glacier inventory was compiled in 1993, there has not been a readily available digital version. Here we present a new digital glacier database, which will be available through the GLIMS project. Glacier outlines have been created for the years 1936, 1966-71, 1990, and 2001-2010. For most glaciers, outlines are available from more than one of these years. A complete coverage of Svalbard is available for the 2001-2010 dataset. Glacier outlines were created using cartographic data from the original Norwegian Polar Institute topographic map series of Svalbard as basis by delineating individual glaciers and ice streams, assigning unique identification codes relating to the hydrological watersheds, digitizing center-lines, and providing a number of attributes for each glacier mask. The 2001-2010 glacier outlines are derived from orthorectified satellite images acquired from the SPOT-5 and ASTER satellite sensors. In areas where coverage for all time periods is available, the overwhelming majority of glaciers are observed to be in sustained retreat over the period from 1936-2010.
This study was conducted in a collaboration between the Department of Geoscience, University of Oslo, and the Norwegian Polar Institute, it was supported by the European Space Agency (ESA) through the projects Glaciers_CCI (4000101778/10/I-AM) and Cryoclim, which is also supported by the Norwegian Space Centre.

Quality controlled timeseries from Norwegian weather station 0-578-0-99790. Data are climate consistent following a number of automated and manual quality control routines.
This publication presents a dataset based on keying/tabulation/quality control of weather, sea ice and whale catch data from several catch logbooks of the Norwegian whaling company Thor Dahl A/S for the period of 1932-1963. These catch logbooks were logged during the whaling season while vessel was on the hunting grounds in the Southern Ocean. The logbooks used in this dataset were originally archived in Hvalfangstmuseet (Whaling Museum) in Sandefjord, Norway, which keeps much of the archive material connected to the Norwegian historical whaling industry. Later the documents were moved to the Vestfold archive in Sandefjord. During this study 56 catch logbooks were keyed and analysed. These catch logbooks cover the whaling seasons of 1932/33 to 1962/63, during which a total catch of 12 747 Blue whales was recorded. All relevant information about the catch (species and number) with associated ship positions, dates, weather and sea ice/icebergs conditions were keyed/tabulated into Excel spreadsheet. For details on the structure of catch logbooks as well as final published data structure, please see the attached metadata file.
The data set presents keyed and translated daily meteorological observations conducted on the whaling station (land base) owned by Hektor Company at Deception Island, the South Shetland Islands archipelago, Antarctica. The original documents is a ship whale catch log (“Fangstdagbok”) that was used to record daily weather events together with the economical activity on the land base. The logbook covers the period of 01.11.1930 to 09.04.1931 and contains daily meteorological observations, such as air temperature and air pressure, wind strength and direction as well as description of specific atmospheric/precipitation events. The data set comprises two files: Deception_island_meteorological_logbook_1930_1931.docx (data set descriptor) and deception_isl_dagbok_1930_keyed_translated.xlsx (metadata and data table).
The data set presents keyed and translated from Norwegian daily observations of sea ice and icebergs conducted onboard research vessel “Norvegia” (D/S Norvegia) during its navigation around Antarctica in the austral summer of 1930-1931. The data covers the period of 20.10.1930 to 09.02.1931.

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.

Abstract:
Quality controlled timeseries from Norwegian weather station 0-578-0-99765. Data are climate consistent following a number of automated and manual quality control routines.
A 2800-yr-long August sea surface temperature (aSST) record based on fossil diatom assemblages is generated from a marine sediment core from the northern subpolar North Atlantic.
The record is compared with the aSST record from the Norwegian Sea to explore the variability of the aSST gradient between these areas during the late Holocene.
The aSST records demonstrate the opposite climate tendencies toward a persistent warming in the core site in the subpolar North Atlantic and cooling in the Norwegian Sea. At the multicentennial scale of aSST variability of 600-900 yr, the records are nearly in antiphase with warmer (colder) periods in the subpolar North Atlantic corresponding to the colder (warmer) periods in the Norwegian Sea. At the shorter time scale of 200-450 yr, the records display a phase-locked behavior with a tendency for the positive aSST anomalies in the Norwegian Sea to lead, by ~30 yr, the negative aSST anomalies in the subpolar North Atlantic. This apparent aSST seesaw might have an effect on two major anomalies of the European climate of the past Millennium: Medieval Warm Period (MWP) and the Little Ice Age (LIA). During the MWP warming of the sea surface in the Norwegian Sea occurred in parallel with cooling in the northern subpolar North Atlantic, whereas the opposite pattern emerged during the LIA.
The results suggest that the observed aSST seesaw between the subpolar North Atlantic and the Norwegian Sea could be a surface expression of the variability of the eastern and western branches of the Atlantic meridional overturning circulation (AMOC) with a possible amplification through atmospheric feedback.

Core Rapid 21-COM represents a composite of two individual sediment cores (Rapid 21-12B and Rapid 21-3K), which were recovered from the southern limb of the Gardar Drift, south of Iceland, during the RRS Charles Darwin cruise 159 in 2004. The age model for core Rapid 21-COM is based on 210Pb dating for the 54.3-cm-long sediment box-core Rapid 21-12B (Boessenkool et al. 2007) and on 14C dating for the 372.5-cm-long kasten core Rapid 21-3K (Boessenkool et al. 2007; Sicre et al. 2011). The previously published diatom-based aSST record from core Rapid 21–12B has 2-yr-average resolution for the last 230 years (Miettinen et al. 2011). Core Rapid 21-3K was sampled continuously at 1.0-cm intervals and analyzed at 1- to 5-cm intervals with a resolution of 8-10 yr for the interval AD 800-1770, representing the highest-resolution diatom SST reconstruction from the subpolar North Atlantic for this period, and 40 yr for interval 0-AD 800.
