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 and phrases embedded in quotation marks. Logical operators include AND, OR and NOT. Remember to add space around operators. Text strings that are not quoted are trated as separate words and will match any of the words (i.e. assuming the OR operator). E.g. in order to find WMO synoptic weather station data from Verlegenhuken use the search phrase: [synop AND verlegenhuken]. 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.
Collections
Collections allows the user to search in subsets of the existing catalogue. The collections are primarily data management projects that have been incorporated in the ADC catalogue after the project has ended. In this context the ADC is the long term access solution for these data. The collections currently served through ADC include (datasets may belong to multiple data collections):
ADC is the full collection of this service CC is the CryoClim collection
In order to search a specific data collection select that collection. If no data collection is selected all collections are searched.
AeN are data related to the Nansen Legacy project and are better explored through the SIOS Data Access Point using the collection defined there which is available through this URL.
SIOS, InfraNOR, SIOSCD, SIOSAP, SESS_* are collections related to SIOS. These are better explored through the SIOS Data Access Portal
Some cleaning is pending between InfraNOR and SIOSIN, for some of the SESS collections.
Citation of data and service
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)
The information required to properly cite a dataset is normally provided in the discovery metadata the datasets.
If you use data retrieved through this portal, please acknowledge the Norwegian Meteorological Institute/Arctic Data Centre.
Measurements of: surface UV radiation, global solar radiation and ground albedo at Polish Polar Station Horsund, Svalbard. Using for masseur passive instruments.
Zooplankton were collected from Liefdefjorden (79°37 N, 12°57 E), and Kongsfjorden (78°96 N, 11°94 E), Svalbard, Norway, during cruises with R/V Teisten and R/V Lance (18-27 July 2008). In addition, a smaller set of samples was collected on the shelf break outside of Kongsfjorden (78°94 N, 8°54 E), for reference/comparative purposes.
Repeated DGPS measurements of (~20) mass balance stakes on the Austfonna ice cap and continuous GPS records on two fast flowing outlets (along the central flowlines of Basin-3 and Duvebreen; 5 units each). The continous measurements are made in cooperation with IMAU, Utrecht, The Netherlands and the present data set overlaps with the one provided by Dr. C.H. Tijm-Reijmer (entry-ID: Flow_Arctic_Glaciers_Tijm-Reijmer_IPY37_NL)
Mean sea ice charts have been calculated based on daily or weekly ice charts produced by NPI and met.no since 1967 to the present day. The original charts are based on satellite imagery, primarily SSM/I with a spatial resolution of 25km. Therefore the mean ice charts were also calculated at a grid resolution of 25km consistent with the original data. The mean ice charts have been calculated for monthly means, 10 year monthly means, and 30 year monthly means.
Background: Long time series of marine fauna and flora in the Arctic are rare. However, since the 1970’s, Norwegian scientists have both jointly with other international partners and independently been investigating the fjords and coastal areas of the arctic archipelago of Svalbard and surrounding seas. More recently, these research co-operation activities have been formalised through participation in the ARCTOS network. These research groups have access to the best available data to assess past changes in shallow Arctic pelagic and benthic ecosystems. In particular good baseline data from Kongsfjorden. In 1996, a transect of ten stations (NPI) was established from the inner part of the Kongsfjord to outside the shelf break at five discrete depth strata, and has been sampled several times a year. The data have been continuously processed until summer 2006. Additionally, a large data set has been gathered on fatty acid trophic markers and stable isotopes of zooplankton, fish and marine birds. Data on the taxonomic composition and structure of soft sediment environments have been gathered approximately every fifth year since 1997 by Akvaplan-niva and the Institute of Oceanology, PAS. The state of the Kongsfjorden ecosystem has been reviewed by several authors and the potential effect of climate swings by Falk-Petersen et al. (2007).Concurrent with the efforts made by ARCTOS, the Alfred Wegener Institute for Polar and Marine Research (AWI) established the 'HAUSGARTEN' in 1999 as the first and only long-term deep-sea observatory at high latitude (Soltwedel et al., 2005). It comprises 15 permanent sampling stations along a bathymetric transect from the Vestnesa Ridge to the Molloy Hole (1200-5500 m) and a latitudinal transect along the 2500 m isobath. These transects cross at the central HAUSGARTEN station, which serves as an experimental area for long-term experiments. Long-term investigations at HAUSGARTEN comprise various compartments of the ecosystem, including the water column and the deep seafloor. Repeated sampling and the deployment of moorings and long-term free-falling systems (bottom landers) has been conducted on an annual basis since 1999 and yielded an unrivalled time-series data set.Aim:•Connect the “Kongsfjord” and “HAUSGARTEN” bathymetric transects •Standardise the sampling strategy and protocol of both transects •Investigate the spatial distribution of zooplankton and benthos by use of existing data and new data collected by remote sensing techniques •Investigate seasonal and diel vertical migration by use of sediment traps and acoustic methods•Assess Arctic pelagic and benthic ecosystem changes in relation to climate factors such as sea ice, hydrography, NAO and AO indices•Adapt and apply existing models on marginal ice zone (MIZ) pelagic-benthic interactions in shallow waters to the HAUSGARTEN bathymetric transect data set•Set a baseline for future monitoring programmes with respect to megafaunal communities and food web structure at selected stations
