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.
Other catalogs through this service are AMAP, ENVINET and SEARCH, or refer to the full list of projects/activities.

At present, Sweden has 4 integrated monitoring (IM) sites that are part of a European network on integrated monitoring with an extensive measurement program. One of these sites, Gammtratten, situated in central Västerbotten, monitors several variables. This program is part of the International Cooperative Programme (ICP) on Integrated Monitoring (IM) of Air Pollution Effects on Ecosystems In Sweden there are three IM-sites, out of which Gammtratten in northern Sweden is one. The IM program at Gammtratten is performed by a consortium including IVL, SGU and SLU-EA. Basically there are three types of monitoring at the IM-sites, viz.

Iceland GeoSurvey ÍSOR is a self‐financing, state‐owned, non‐profit institution in the field of natural sciences, it’s main activity being related to the geothermal industry in Iceland and abroad. It was established 2003, when the GeoScience Division of Orkustofnun (the National Energy Authority of Iceland), was spun off as a separate entity according to the law of Iceland GeoSurvey no. 86, March 26th 2003 (http://www.althingi.is/lagas/135a/2003086.html). The main role of ÍSOR is to work on projects and research in the field of natural resources and energy, as the directive board of the institute decides. ÍSOR offers research consulting services worldwide on most aspects of geothermal exploration, development, and utilization, and provide training and education on related issues. It is based on six decades of continuous experience in the field of geothermal and hydropower research and development. The focus is on geothermal exploration, development, and utilization, but cover also many other geoscience‐related fields as well, including groundwater studies, marine geology, and environmental monitoring.

The sample plot-based national forest inventory (RIS-RT) has been a continuous activity at SLU (and the forest research organizations existing before SLU) since 1923. All Sweden is included except the subalpine birch forest along the mountain chain. The national forest inventory is part of Sweden’s official statistics and is maintained by the Department of Forest Resource Management (SLU-FRM). The sampling strategy combines random and fixed plots and covers the country every 5 years. Each year around 10 000 sample plots are field surveyed nationwide. Approximately 200 variables are recorded for each plot.
Italy’s leading national research institution, the CNR has been supporting research activity at Ny-Ålesund since 1997, when the scientific station “Dirigibile Italia” was acquired. This infrastructure supports Arctic research conducted by the national research community. In 2008, it was improved through the construction of the Amundsen-Nobile Climate Change Tower and the actikvity largely enlarged with the Climate Change Tower Integrated Project (CCT-IP - www.isac.cnr.it/~radiclim/CCTower). Scientific cooperation, particularly focused on atmospheric science including pollutants distribution and ozone studies, on oceanography and on marine biology and biodiversity was developed by CNR scientists in particular with NPI and AWI; CNR is coordinating actions (EU-GMOS project) to improve and implement the observational system related to mercury. CNR is also involved in the SIOS preparatory phase project, and in Italy it is engaged to coordinate interested Italian expertises in a common scientific plan and actively promote Italian participation to SIOS final multidisciplinary platform. In the years to come, CNR intends to promote the improvement of research activity and to reinforce international cooperation of the Italian research groups, and to provide a significant contribution to the observational system in the Arctic, following the lines recommended by SAON. Together with the improvement/development of a supersite at Ny-Ålesund and large contribution to SIOS, CNR will operate to contribute/sustain thematic networks (Polar-AOD for aerosol and GMOS for mercury leading from CNR).
The Minister of the Interior is responsible for centrally administrating maritime, harbour and lighthouse affairs, except where otherwise provided for in a different law. The IMA, with a staff of around 70, handles numerous activities in the field of maritime administration and supervision, such as operation of lighthouses and navigational systems, vessel registration and supervision of ship surveys, manning and certification. The IMA also conducts research into ship stability and ship and harbour security and harbour development, coastal changes and coastal protection.

The national program of intensive forest monitoring is managed by the Finnish Forest Research Institute (Metla). In 2011 five of the 18 Finnish intensive monitoring plots situated in Finnish Lapland (Fig. 5.1.: Sevettijärvi, Pallasjärvi and three plots in Kivalo). Finnish national intensive forest monitoring network is part of pan-European ICP Forests network of ca. 800 plots (http://icp-forests.net/page/level-ii). ICP Forests (the International Co-operative Programme on Assessment and Monitoring of Air Pollution Effects on Forests) operates under the UNECE Convention on Long-range Transboundary Air Pollution. These intensive monitoring plots were established in co-operation of ICP Forests and European Commission in mid 1990’s. European Commission co-financed forest monitoring under forest monitoring regulations until the end of 2006 when the Forest Focus regulation (EC No 2152 / 2003) expired. During 2009-2011 part of these intensive forest monitoring plots were included in Life+-project called “FutMon” (Further Development and Implementation of an EU-level Forest Monitoring System: http://www.futmon.org/). Monitoring is carried out following the manual of ICP Forests (http://icp-forests.net/page/icp-forests-manual) and the monitoring data is submitted once a year to the ICP Forests database in Hamburg. Every year Programme Coordinating Centre of ICP Forests publishes technical and executive reports on the condition of forests in Europe. ICP Forests monitoring activities provide information also for a number of criteria and indicators of sustainable forest management as defined by the Forest Europe Ministerial Conference on the Protection of Forests in Europe. Network type: National nation-wide monitoring
The Polar Station of the University of Nicolaus Copernicus is located in the western part of the Oscar II Land, in the northern part of the coastal Kaffiøyra Lowland which is closed by the Forlandsundet from the west. The undertaken research included almost all components of the geographical environment. Scientific programs put pressure on research in glaciology, glacial geomorphology, permafrost and periglacial processes, as well as climatologic and botanical studies. Since 1995 glaciological research and the studies of permafrost of various ground types and their seasonal thawing, as well as meteorological observations have been the major issues on the research agenda. Glaciers pose the dominating feature of the Kaffiøyra region. Since the 19th century their area has decreased by about 30%. Thus, one of the main scientific issues studied there is the course and the reasons for the change in the glaciers’ range. This can be achieved by studying mass balance of the glaciers. Presently, mass balance of four glaciers is studied: the Waldemarbreen, the Irenebreen, the Elisebreen and the Aavatsmarkbreen. 39 The research includes both the summer balance (ablation and outflow from the glaciers) and the winter snow accumulation. The detailed research plans also refer to two large glaciers which end up in the sea. Those are the Aavatsmarkbreen in the north and the Dahlbreen in the south of the Kaffiøyra. Currently, subaquatic glacial relief of the bays in the Forlandsundet region is under scrupulous investigation. The results of the research can be obtained from the station’s website (www.stacja.arktyka.com), from the publications by the World Glaciological Monitoring Service (WGMS- IAHS), as well as the website of the Circumpolar Active Layer Monitoring (CALM- IPA). The research carried out in the N.Copernicus University Polar Station has enabled numerous scientists of most specialties of the Earth sciences (glaciology, climatology, hydrology, geomorphology, pedology and botany) to collect material for numerous papers, including master and doctoral theses. Scientific attractiveness of the Kaffiøyra’s geoecosystem has been appreciated by scientists from various scientific centres in Poland and elsewhere, who take part in interdisciplinary expeditions organized every year. The most Polish polar research in the north-west Spitsbergen is based on the N.Copernicus University Polar Station Once the station has had an extension addend, it can host 10-15 people at any one time. The new section of the station is 32 sq. m downstairs and 24 sq. m upstairs. This includes a study, a workshop, a bedroom as well as two bedroom entresols. The extension is connected with the old section of the station, which includes a living room and a bedroom, but there is also a separate entrance to the new part of the station. Additionally, the station gained extra storage floor, a laboratory, a bathroom, as well as a garage to keep boats, snowmobiles and engines. All together the station now has about 100 sq. m. The station is used 3 to 4 months annually, but it is possible to stay there for as long as a whole year. It is equipped with necessary technical facilities, motor-generators, solar panels, motorboats and snowmobiles. More important measurement equipment includes: a weather station with the basic measuring instruments (the measurements conducted since 1975); automatic weather stations (with the measurements taken at any intervals); limnigraphs and loggers installed in the selected watercourses (measurements of water levels, flow rates and the selected physicochemical features of water since 1975); a system of ablation poles installed on the glaciers; ice drills; loggers for measuring ground temperatures and ice temperatures, and others. The extension of the station in 2007 enabled larger groups of scientists to work and conduct research. The fact that both the living and laboratory space has been enlarged is especially important, as the station is often visited by scientists from all over the world. As a result, the extension will make it possible to intensify current international contacts, as well as start new co-operation projects in the Kaffiøyra region.
The study includes comprehensive study of the geographical environment in the area of Polar Station of Maria Curie-Skłodowska University in Calypsobyen (NW part of Wedel Jarlsberg Land, Svalbard). Currently, studies have been carried out within research projects: - Dynamics of matter circulation in the polar catchment are a subject to deglaciation processes (Scottelva, Spitsbergen) (DYNACAT) - Morphogenetic and morphodynamics conditions of development of the coast of the NW part of Wedel Jarlsberg Land (Spitsbergen) in the late Vistulian and Holocene (MORCOAST) - Mechanisms of fluvial transport and sediment supply to Arctic river channels with various hydrological regimes (SW Spitsbergen) (ARCTFLUX)
The overall goal of AON is to obtain data that will support scientific investigations of Arctic environmental system change. The observing objectives are to: 1. Maintain science-driven observations of environmental system changes that are already underway; 2. Deploy new, science-driven observing systems and be prepared for detection of future environmental system change; 3. Develop observing data sets that will contribute to (a) the understanding of Arctic environmental system change (via analysis, synthesis and modelling) and its connections to the global system, and (b) improved prediction of future Arctic environmental system change and its connections to the global system. Main gaps: Understanding Change and Responding to Change panels, has formed an AON Design and Implementation (ADI) Task Force. Composed of Arctic and non-Arctic scientists with experience and expertise in scientific observing and observing system operation and design, the goal of the task force is to provide advice to the scientific community and NSF on observing system/network design options that are available for identifying gaps that hinder scientific understanding of Arctic environmental system change. The task force will hold two workshops and address two main objectives: (1) evaluate the current SEARCH science questions and observing priorities, and recommend new priorities in the light of the environmental system changes that have occurred since 2005; and (2) evaluate observing system/network design methods, including pilot projects and small-scale tests. A publicly available report will be released in summer 2010. It is anticipated that the report will be of interest to the broader Arctic science community, the governments of the Arctic countries and other countries, NGOs and numerous stakeholders.
At present, Sweden has 4 integrated monitoring (IM) sites that are part of a European network on integrated monitoring with an extensive measurement program. One of these sites, Gammtratten, situated in central Västerbotten, monitors several variables (Table 4, #3.2). SGU conducts groundwater sampling at 3 of the sites. In total, 18 stations are sampled 4 times per year. A program for comprehensive information on the state of forests in Europe was launched 1985 in response to acid deposition and fear of forest decline. The program was named the European ICP-Forest Program (International Co-operative Program on Assessment and Monitoring of Air Pollution Effects on Forests operating under the UNECE Convention on Long-range Transboundary Air Pollution, Table 6, #5). ICP-Forest monitors forest conditions in Europe and operates at two levels of intensity. Level I is a systematic 16 km by 16 km transnational grid having around 6 000 observation plots in Europe. Level II is comprised of around 800 sites in selected forests throughout Europe with more intense observations. The Level I measurements consist of three parts: crown condition assessment, soil condition assessment, and foliar survey. The crown condition assessment includes the degree of defoliation, discoloring, and damage visible on trees. The soil condition assessment addresses possible nutrient imbalances caused by, e.g. acid deposition. The foliar survey assesses foliar nutrient concentrations, because changes in environmental conditions may affect foliar nutrient concentrations. The Swedish contribution is made by the national forest inventory (SLU-FRM), which estimates the degree of crown defoliation and discoloring on 700 permanent plots around the country. The Swedish Forest Agency (SST) organizes the Level II observational plots. They manage a program with more than 200 permanent plots throughout Sweden, on which they estimate forest vitality (several measures), forest growth, soil chemistry, and field vegetation. Of these plots, 100 are connected to the international network, and 20 are north of 60°N. Foliage chemistry is determined on 100 plots, deposition and soil water chemistry on 50 plots, air quality on 25 plots, and climate on 14 plots. The sampling intensity varies from once in 5 years to once per hour depending
The total column amount of ozone and other trace gases are measured with mm-wave instruments, FT-IR and DOAS spectrometers, at IRF in Kiruna (Table 6, #8.1). With the sun or moon as infrared light sources, FT-IR spectrometers can quantify the total column amounts of many important trace gases in the troposphere and stratosphere. At present the following species are retrieved from the Kiruna data: O3 (ozone), ClONO2, HNO3, HCl, CFC-11, CFC-12, CFC- 22, NO2, N2O, NO, HF, C2H2, C2H4, C2H6, CH4, CO, COF2, H2O, HCN, HO2NO2, NH3, N2, and OCS. Together with Russian and Finnish institutes at the same latitude, IRF studies the stratospheric ozone and its dependence on polar atmospheric circulation and precipitation of charged particles. The ground-based instruments are also used to validate satellite measurements of vertical ozone distribution (Odin, SAGE III, and GOME). Aerosols and thin clouds are measured at IRF in Kiruna. For example, researchers use Lidars (Light Detection and Ranging) to measure polar stratospheric and noctilucent clouds. Winds and structures are measured with ESRAD MST radar at IRF in Kiruna. At IRF in Kiruna measurements are used to assess the physical and chemical state of the stratosphere and upper troposphere and the impact of changes on the global climate. Particle precipitation is measured by relative ionospheric opacity meters (riometers) at IRF in Kiruna. Riometers measure the absorption of cosmic noise at 30 and 38 MHz and provide information about particles with energies larger than 10 keV. The electron density of the ionosphere is measured by ionosonds and digisondes at IRF in Kiruna.
Deposition measurements are mainly made in forest injury observation plots laid out by the Swedish Forestry Agency (SST). The observations made are: Air Chemistry: SO2, NO2, NH3, O3 Soil Water Chemistry: pH, Alk, SO4-S, Cl, NO3-N, NH4-N, Ca, Mg, Na, K, Mn, Fe, ooAl, oAl, Al-tot, TOC Deposition open field precipitation: H+, SO4-S, Cl, NO3-N, NH4-N, Ca, Mg, Na, K, Mn Deposition in forest throughfall: H+, SO4-S, Cl, NO3-N, NH4-N, Ca, Mg, Na, K, Mn A notorious problem in deposition assessments is dry deposition on forest canopies. If throughfall is sampled below the canopy it will consist not only of dry and wet deposition, but also of canopy leakage, i.e. exudates and diffusion of substances from within the leaves. However, it has been argued that throughfall sampling, even if not free from problems, may add information to the normal wet deposition sampling. IVL operates a throughfall sampling network comprised of 10 forest sites for sampling, from which monthly samples are analyzed for pH, SO4, NO3, NH4, Kjeldahl-N, Cl, K, Ca, Na, Mg, TOC, conductivity, alkalinity, and amount of throughfall.
Calculating deposition in a grid over Sweden showed the lack of information on deposition at high altitude. SMHI applied the meso scale MATCH model to calculate the deposition field and the matched model is called MATCH-Sweden. The result is found at http://www.smhi.se/cmp/jsp/polopoly.jsp?d=5640&l=sv The observations made at these stations are: Particles in air: SO4-S, NO3-N, NH4-N, Cl, Na, Ca, Mg, K Gase:s NH3-N, HNO3-N, SO2-S Deposition open field precipitation: H+, SO4-S, Cl, NO3-N, NH4-N, Ca, Mg, Na, K Deposition in forest throughfall: H+, SO4-S, Cl, NO3-N, NH4-N, Ca, Mg, Na, K To integrate the relatively few deposition measurement sites, SMHI has adopted the Mesoscale Atmospheric Transport and Chemistry Model (MATCH) that uses emission data, meteorological data, routines for chemical processes, and a transport model to calculate long-range transport and deposition of air pollutants (Table 4, #1.5). Time series of gridded data over Sweden for deposition of different inorganic chemical compounds calculated with the MATCH-Sweden model are available at SMHI (Appendix, Table 11). When the MATCH-Sweden model was first tested, the deposition network lacked high elevation sites. Hence, a monitoring program for deposition at higher elevations (Table 4, #1.9) was started. It consists of 4 sites in high elevation forests along the Swedish mountain ridge, where NO3, NH4, NH3, HNO3, SO2, SO4, Na, K, Ca, Mg, Cl, pH, conductivity, and amount of precipitation are analyzed on monthly accumulated precipitation samples.
Investigations within many areas of biosciences and geosciences are carried out at the station. The emphasis of staff research is on plant ecology and meteorology. The main objectives of the ecological projects are to study the dynamics of plant populations and to identify the controlling factors at their latitudinal and altitudinal limits. The meteorological projects deal with recent climate changes in the region, and also with local variations of the microclimate in subalpine and alpine ecosystems.
The Faculty of Forestry at SLU has two research stations with experimental forests, two experimental forests with permanent staff, three without permanent staff and a large number of long-term field trials. These facilities are spread over the country.
