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 SAON Data Portal.
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 through the drop down menu above the text field. Text strings that are not quoted are treated as separate words and will match any of the words (i.e. assuming the OR operator). Phrases may be prefixed with '-' to indicate no occurence of the phrase in the results.
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.

A Norwegian Ice Drift Experiment (ICEX) started in 1976 as part of a national contribution to the polar programmes under the Global Atmospheric Research Programme (GARP). The main aim of the experiment is to obtain information on an important climatic parameter: the export of ice from the Arctic Ocean through the Fram Strait. The project was reorganized in 1981, and became a joint programme between Norsk Polarinstitutt and Det norske meteorologiske institutt, also involving cooperation with the University of Washington’s Arctic Ocean Buoy Program.
An ICEX measuring capsule has been developed in cooperation with Chr. Michelsens Institutt, Bergen, (Vinje & Steinbakke 1976, Nergaard et al. 1985). The capsule operates effectively in the marginal sea ice areas where it may be subject to frequent ridging and sporadic drift in water. The buoys were deployed from a boat in a pilot project in 1975, from a Cessna 185 aircraft landing on the ice in 1976 and 1977, and they have been air-dropped by the Norwegian Air Force from 1978 onwards. Since 1981 data from the Norwegian buoys have been included in the Arctic Ocean Buoy Program data reports edited by the Polar Science Center, University of Washington.
The present data report contains drift tracks and daily values of positions, air pressure (P) mb, air temperatures (TA) about 80 cm above the ice surface, and temperatures (TB) at the bottom of the ICEX capsule. The latter information indicates if the measuring capsule is on the ice or in the water. When free floating, (TB) gives the temperature about 40 cm below the sea surface.
During the first five years of the experiment, the air pressure sensors were built at the Norwegian Meteorological Institute, based on an aneroid and a displacement transducer. Another Norwegian pressure transducer has been produced by Aanderaa Instruments. This is based on a silicon chip as sensing element. The Digiquarts pressure sensor from the US firm Paro Scientific has also been used since 1981. The sensor resolution is hetter than 0.1 mb, while the system resolution is 0.4 mb within the normal variation range of the meteorological variables. Series of comparisons in the field showed that the mean difference between the data obtained via Nimbus-6 and the readings on a test set was less than 0.1 mb (Vinje 1978). Later comparisons showed differences of about 1 mb (Vinje 1981). This was, however, well inside the FGGE requirements.
The temperature is measured with a radiation shielded termistor. Fenwal UUA 3213. The system resolution is 0.2°C. The ventilation of the sensor is dependent upon the wind speed, and the sensor signal is also dependent upon the heating of the capsule. A series of comparisons in the field showed that the temperatures were correct within ±0.1 °C during conditions with normal ventilation (Vinje 1981). A comparison on Fram Ill (Thorndike et al. 1982) during part of April 1981 indicated temperatures as much as 1 °C - 2°C too high during the warmest part of each day. Otherwise the daily cycle was well resolved and the temperature readings from the ICEX buoy agreed well with the met observer’s data.
