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.

Abstract:
The files contain data from NCAR GPS dropsondes AVAPS (Airborne Vertical
Atmospheric Profiling System), taken during the Norwegian IPY-THORPEX field
campaign from 25 February to 17 March 2008. A description of AVAPS is given
in: http://www.eol.ucar.edu/isf/facilities/dropsonde/ The data has been
post-processed and quality controlled with the Atmospheric Sounding Processing
Environment (ASPEN). For more information, see:
http://www.eol.ucar.edu/isf/facilities/software/aspen/aspen.html
During the
campaign period the DLR Falcon 20 was stationed at Andenes airport in Norway and
used for flight missions for the study of adverse weather in the Arctic region.
The field campaign had a particular focus on polar lows. Two such events was
measured during the campaign period, 3-4 March and 17 March. The 3-4 March case
was measured by 3 flight missions, documenting the full life cycle of a polar
low. The IPY-THORPEX project is described in: http://www.ipy-thorpex.no. A
description of each flight, including the flight plansas given in: http://www.pa.op.dlr.de/ipy_thorpex/

We conducted CH4 flux measurements by the closed chamber technique at 18 locations near the terminus of the Gulkana Glacier, the Alaska Range, in mid-July 2019. We also measured suppoted data of air temperature, EC of the water, CO2 flux.
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.
Research cruise in the Arctic Ocean by T/S Oshoro Maru in 2017 is partly supported by the governmental project on the Arctic environment, Arctic Challenge for Sustainability (ArCS), and carry out various surveys on oceanography and ecosystem with a theme 'Response and biodiversity status of the Arctic ecosystems under environmental change'.

We made a detailed investigation of the appearance and coverage of lichen species near Ny-Alesund, Svalbard, High Arctic Norway, in 1994. We identified 82 lichen species, and our data clearly show their forms, location, and microtopography. This information will be useful for understanding future vegetation changes.
Marine CO2 system data (total alkalinity, total dissolved inorganic carbon and pH on the total scale) were collected from 8 to 12 discrete depths in January, May, August 2014 on repeat stations in the eastern Fram Strait along 79N, and north of Svalbard. The seawater samples were collected from a CTD-Rosette (12-Niskin bottle) following standard procedures and analyzed at Institute of Marine Research, Tromsø, Norway. The DIC and AT were analyzed after the cruises at the Institute of Marine Research (IMR Tromsø, Norway) following the method described in Dickson et al. (2007). DIC was determined using gas extraction of acidified samples followed
by coulometric titration and photometric detection using a Versatile Instrument for the Determination of Titration carbonate (VINDTA 3D, Marianda, Germany). determined by potentiometric titration with 0.1 N hydrochloric acid using a Versatile Instrument for the Determination of Titration Alkalinity (VINDTA 3S, Marianda, Germany). Routine
analyses of Certified Reference Materials (CRM, provided by A. G. Dickson, Scripps Institution of Oceanography, United States) ensured the accuracy of the measurements, which was better than ±1 and ±2 mmol kg-1 for DIC and AT, respectively. pH was determined onboard in January 2014 using a diode-array spectrophotometer and the unpurified indicator dye m-cresol purple (mCP) following the method of Clayton and Byrne (1993). The perturbation of the sample pH due to the addition of the indicator dye was corrected for according to Chierici et al. (1999). The precision was generally around ± 0.001. Description of the analytical methods can be found as a summary in the data file.
Water samples for analysis of nutrients [NO2, NO-, Si(OH)4, PO4] were frozen until post-cruise analysis by standard methods (Grasshoff et al., 2009) using a Flow Solution IV analyzer from O.I. Analytical, United States. The analyzer was calibrated using reference seawater from Ocean Scientific International Ltd., United Kingdom. Three replicates were analyzed for each sample. Note that we refer to the NO3- concentration throughout the study, but it is actually the sum of NO2 and NO3, since NO2 levels are considered to be low in this area (Codispoti et al., 2005).
This study is a contribution to the Carbon Bridge (RCN-226415) project funded by the Norwegian Research Council and the Flagship Research Program “Ocean
acidification and effects in Northern waters” within the FRAM-High North Research Centre for Climate and Environment.
