Functional outline of the data portal search interface.
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 by changing the operators used in the text field and prefixing words with '+' and '-' to indicate whether they have to be present or should not be present 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.

Abstract:
The CryoClim FSC product provides daily information on fractional snow cover(0-100 %) per grid cell for global land areas except permanent snow and iceareas with 5 km grid size. The product is based on multi-sensor/time-series fusion of AVHRR, SMMR, SSM/I and SSMIS data eliminating cloud cover and polar night, resulting in a temporally consistent snow map.

Automatic weather station (AWS) on Etonbreen glacier, an outlet from the Austfonna ice cap in North-East Svalbard. The AWS is located at approx 360 m a.s.l. near the long term equilibrium line altitude. The AWS records variables needed for an energy balance assessment. The AWS records Air Temperature, Relative Humidity, Wind Direction and Speed, Air Pressure, Snow Height, Longwave and Shortwave radiations. Data are transferred by Iridium. The extended AWS is the same type of station with heated and ventilated radiation in addition.

Abstract:
A set of inter calibrated salinity in-depth profiles in Hornsund Fjord.We used all of our CTD sensors (Valeport: 1 CTD; RBR: 3 CTD, 2TD, 6 T; SeaBird 1CT; SAIV A/S: 1 CTD), at the same time in a stable position at stable depths for 24 hours measurement. SAIV A/S conductivity data was different from the rest. Because for CTD in-depth profile Valeport and SAIV A/S were used we made comparable CTD in-depths profiles for these two CTD sensors. Based on comparison plots for temperature and conductivity from the same depths for all comparable in-depth profiles for these two sensors we add linear correction for temperature and conductivity data from SAIV A/S. After losing SAIV A/S sensor we made the same procedure for the new. Depth (UNESCO Technical Papers in Marine Science No. 44), salinity (UNESCO 1983), density (Millero and Poisson 1981, UNESCO 1981) were calculated based on a commonly used formula from pressure, temperature, and conductivity after data inter-calibration.

Abstract:
The product is based on a manual interpolation of available insitu observations. This dataset is the predecessor of the gridded ice charts based on satellite data and other sources. This dataset primarily identifies the sea ice edge.
Weekly Southern Ocean ice limits, have been digitized from U.S. Navy Fleet Weather Facility ice charts, at the Max-Planck Institut fur Meteorologie, Hamburg. Coverage is from 1 January 1973 to 31 June 1978. Data are gridded at 5 degree longitude intervals and are available via ftp.
<strong>Note:</strong> NOAA@NSIDC believes these data to be of value, however, they should be used with caution because we are unable to quality check the data or provide documentation due to lack of funding.
