The purpose of the Sustaining Arctic Observing Networks (SAON) is to support and strengthen the development of multinational engagement for sustained and coordinated pan-Arctic observing and data sharing systems. SAON was initiated by the Arctic Council and the International Arctic Science Committee, and was established by the 2011 Ministerial Meeting in Nuuk.
The SAON inventory builds on a survey circulated in the community at the inception of the activity. This database is continously updated and maintained, and contains projects, activities, networks and programmes related to environmental observation in the circum-polar Arctic.

Fluvial transport, its dynamics and structure, constitute a good indicator of the condition of the natural environment in various climatic zones. Analysis of fluvial transport components allows for precise determination of the rate and directions of transformations of geosystems of any importance. In the polar zone, very sensitive to global changes, it seems expedient to identify the mechanisms and structure of fluvial transport, particularly in the conditions of the observed glacier retreat, the main alimentation source of proglacial rivers. Studies carried out in the zone revealed difficulties in determination of fluvial transport structure, particularly the actual bedload of gravel-bed rivers based on direct measurements, resulting from: short measurement series, lack of standardization of research methods and measurement equipment, and strategy of selection of study objects and sampling. The research project presented concerns determination of mechanisms of fluvial transport and sediment supply to Arctic gravel-bed river channels. The mechanisms reflect the processes of adaptation of proglacial rivers of the Arctic zone to changing environmental conditions, and indicate the dominant directions of transformations of paraglacial geosystems of various importance. For studies on Arctic geosystems, the region of the south Bellsund (SW Spitsbergen) was selected due to extensive knowledge on its hydro-meteorological and glacial-geomorphological conditions, and long-term measurement series carried out by the research station of the MCSU, among others within the framework of the international monitoring network: SEDIBUD (IAG) and Small-CATCHMENT program. For detailed studies, rivers with various hydrological regimes were selected, functioning at the forefield of the Scott and Renard Glaciers. The Scott River glacial catchment and glacier-free catchments of the Reindeer Stream and the Wydrzyca Stream (with a snow-permafrost hydrological regime) meet the selection criteria for representative test catchments analyzed for the following programs: SEDIFLUX, SEDIBUD, and POP.
The main objective of National Land Survey of Iceland is to provide and share geographical information on Iceland. The Survey gathers and sells digital data on Iceland as well as selling digital aerial photos. The institute is located at Stillholt 16‐18 in Akranes 50 km from Reyekjavik where it has been located since January 1, 1999. The institute currently has a staff of 29. Main gaps: Not specified Network type: Thematic observations
The subprogram main task is to check if international agreements as the UN Convention on Long Range Transboundary Air Pollution (CLTRAP) are followed. EMEP = European Monitoring and Evaluation Programme. The network comprises 10 stations, out of which three are in northern Sweden. Air chemistry is monitored by diffusion samplers. The following compounds are measured: SO2, SO4, tot-NH4, tot-NO3, soot, NO2, O3 Precipitation quality is monitored by samplers with lid, open only when it rains. The following compounds are measured: SO4-S, NO-N, Cl, NH4-N, Ca, Mg, Na, K, pH, EC. Ozone near ground is analyzed every hour and is part of an European warning system PM10 is particles Metals in air and precipitation is analysed at Bredkälen only. The following elements are analyzed: As, Cd, Co, Cr, Cu, Mn, Ni, Pb, Zn, V, Hg, metyl-Hg.
