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.
Map compilation from aerial photographs of 1969, 1983 and from result of control point survey implemented by Japanese Antarctic Research Expeditions 1983-1985.The numbered grid lines are 1km intervals of the UTM-grid (Zone 37). Coordinates of the origin of projection (39E , 0S) correspond to 500kmE and 10,000kmN on this grid.
Orthophoto Image is an image that color aerial photograph is converted to orthophoto and mosaic effects are added to it. Geometrically corrected data is available
Geological map data of Antarctica held by the National Institute of Polar Research and the Geospatial Information Authority of Japan. There are two types of data available: (data1: geometrically corrected data) and (data2: raw image data).

Abstract:
Carbon cycling in a black spruce stands was estimated in Caribou-Poker Creek Watershed, Interior Alaska. Carbon dymanics monitoring sites were settled along the northeast-facing slope. In 2015 September, we surveyed tree census and permafrost table detection along the true north-facing slope. One site was located on upper position of the north-facing slope, the other at the lower position. Totally 160 individual trees were measured. The depth of permafrost table were estimated by penetrationg test at three points in each census plot. The permafrost depth at upper site were 47cm, 66cm, and 68cm. At the lower site, the depth were 39cm, 28cm, and 38cm.

Abstract:
Time-series data of an automatic weather station (AWS) operated at the SIGMA-B site on the Ice cap of Greenland since July 2012. The AWS measures the meteorological parameters every hour, which are air temperature, relative humidity, wind speed, wind direction, atmospheric pressure, shortwave radiation, longwave radiation, and snow height. This dataset (data level: 1.2) has been applied brief data masking procedures discriminating apparent erroneous data records. Detailed information of the data level definition is referred to "readme_SIGMA-B_Level_1.2.txt".
Black carbon (BC) aerosol deposited in and onto Arctic snow increases the snow's absorption of sunlight and accelerates snowmelt. Wet removal of BC from the atmosphere plays a key role in determining its abundance in the Arctic atmosphere and in Arctic snow. However, this process is poorly understood, mainly due to the scarcity of relevant measurements. To reveal characteristic features of the wet deposition of BC, we made measurements of mass concentration of BC in snow and rain (C_MBC) with relatively high (16%) accuracy and mass concentration of BC in air (M_BC) at the Barrow Atmospheric Baseline Observatory, Alaska, from July 2013 to August 2017 and analyzed them along with routinely measured meteorological parameters from Barrow. Monthly mean M_BC near the surface and C_MBC were poorly correlated from midwinter to early spring, when C_MBC was close to the annual median while M_BC was at its annual peak. Seasonal variations in the altitude distribution of M_BC may lead to these differences in seasonal variation of M_BC near the surface and C_MBC. About 50% of the annual wet deposition of BC occurred in the three months of summer, associated with high values of total precipitation and BC originating from biomass burning. Size distributions of BC in snow and rain were stable throughout the year, suggesting that the size distribution of BC in the lower troposphere was similarly stable. Calculations by two global models reproduced the observed seasonal variations of C_MBC and showed that BC from biomass burning dominated C_MBC in summer.
This dataset contains the ice thickness data recorded in the Dome Fuji region, East Antarctica. The data was recorded by the 59th Japanese Antarctic Research Expedition (JARE59) using a pulse-modulated POL radar sounder with a peak transmission power of 1kW, a center frequency of 179 MHz and a transmitter pulse width of 500, 100 or 60 ns.

Abstract:
Our research area is located near Chokurdakh (71N, 148E) in Northeastern Siberia, Russia, about 150 km inland from the Arctic sea coast along the Indigirka River. Carbon and energy fluxes were observed at Kodac station which is situated in a forest-tundra landscape. The observations using 3m flux tower (sensors are installed at 2.55m height) include carbon dioxide, latent heat and sensible heat flux monitorings.
