1. Measurements of climate-influencing substances on Svalbard

National Environmental Monitoring in Sweden in the "Air" programme. The objective of the project is to follow climate-changing gases and particles and which effects they could have on the climate of earth. To understand and assess the human effect on the climate, regionally and globally, the atmospheric aerosols and greenhouse gases are monitored. The project aims follow: (i) detecting long-term trends in the carbon dioxide level, as well as trends in the amount or composition of aerosols in the background atmosphere; (ii) provide a basis to study the processes that control the aerosol life cycle from their formation through aging and transformation, until being removed from the atmosphere; (iii) provide a basis to study the processes (sources, sinks, and transport pathways) that control the level of carbon dioxide in the atmosphere; (iv) contribute to the global network of stations that perform continous measurements of atmospheric particles and trace gases to determine their effect on the earths radiation balance and interaction with clouds and climate.

2. Radnett – a national network for monitoring radioactivity in the environment

The Norwegian Radiation Protection Authority is responsible for a nationwide network of 33 stations that continuously measure background radiation levels. The network was established in the years following the Chernobyl accident in 1986, and was upgraded to a new and modern network in the period 2006-2008. Additional stations were added in 2009. The purpose of the monitoring network is to provide an early warning if radioactive emissions reach Norway.

3. Ecogeochemical mapping of the eastern Barents Region (Barents Ecogeochemistry)

Geochemical mapping project based on multimaterial and -elemental method covering the NW Russia and adjacent areas of Finland and Norway. NW-Russia is of strategic importance not only for Europe but also for the sosio-economic development of the whole Russia for its richness in natural resources. Their use must be based on environmentally acceptable principles. In addition, within the area exist numerous industrial centres whose environmental impacts are unknown. The information produced by the project is significant for the future development of the area and remedial measures of the environment. The project lead by the applicant, will be carried out in 1999-2003 in cooperation with Russian and Norwegian partners.

4. Whole body measurements on reindeer herders in Finnmark, Norway

Elevated levels of 137Cs caused by previous atmospheric nuclear weapons tests fallout and the Chernobyl accident have been observed in Finnmark, Northern Norway. Due to the large consumption of potentially contaminated reindeer meat, whole body measurements of 137Cs levels in reindeer herders have been performed since 1965.

5. Monitoring POPs and heavy metals in the merlin (Falco columbarius)

To monitor levels of pollutants in merlin by analysis of POPs and heavy metals in eggs and feathers. /Feathers and addled eggs of merlin were collected in 1992, 1993, 1994, 1999 and 2000 for chemical analysis of POPs and heavy metals. Comparisons with eggs from museum collections show that there has been a significant shell thinning in eggs of Norwegian merlins. From 1947 up to 1990 the eggs were on average ca. 15% thinner than normal and after 1990 the thinning has been ca. 10%. There are still high concentrations of DDE to reduce reproductive output in some cases. The PCB levels are low compared to the DDE levels and the concentrations of other chlorinated hydrocarbons are also low. Results from mercury analyses indicate possible effects on breeding performance in some adults.

6. Effects of Persistent Organic Pollutants (POPs) on the Immune Response of Glaucous Gull (Larus hyperboreus)

The present project includes one pilot study of wild adult glaucous gull (Larus hyperboreus) and one experimental study of glaucous gull chicks raised in captivity. The pilot study of adult gulls gave us enough blood and tissue samples to develop the methods needed for immune system analysis in the laboratory experiment. In the experimental study a total of 39 glaucous gull chicks were hatched and raised in captivity in Svalbard, Norway. The chicks were divided into two groups. One experimental group (20 chicks) was given food that mimicked the “natural” food found in the marine environment. The control group (19 chicks) was given “clean” food. After 56 days the chicks were sacrificed in order to collect samples for analyses of organochlorines (OCs) and immunocompetence measurements. The experimental group had 2.8, 3.9, 5.0, and 6.1 time’s higher concentrations of HCB, Oxychlordane, ?DDT, and ?PCB, respectively, compared to the control group at day 56. All chicks used in the experiment were immunised with various vaccines and sera in order to test their ability to respond against foreign antigens. The experimental chicks produced low levels of virus neutralising antibodies when tested against the herpes virus and reovirus. They produced higher levels of neutralising antibodies when tested to tetanus toxoid. There was, however, no difference between the experimental groups with regard to the mean antibody titres. The chicks in both groups also responded to the influenza virus by increasing the production of specific antibodies. However, the mean antibody titre in the exposed group was significantly lower than in the control group. The mitogen-induced response of blood lymphocytes to PHA and LPS was significantly higher in the exposed group compared to the control group. The specific response of blood lymphocytes to Con A, PWM, KLH, TET, and PPD was higher in the exposed group compared to the control group. However, do to high variance in the exposed group there was no significant difference between groups with regard to the lymphocyte response to these mitogens. The results from the present study indicate a toxic effect of OCs on the glaucous gull chicks, which induced a systematic activation of the immune system. Further work on data will be performed.

9. Terrestrial monitoring programme. Studies in vegetation ecology of boreal birch forests in Børgefjell National Park, N Norway

In 1990, the Directorate for Nature Management (DN) established an area for integrated monitoring within Børgefjell National Park, Røyrvik, N Trøndelag. Studies of vegetation-environment relationships in the area was performed by NINA. The area includes both subalpine birch forest and low alpine heath. The new established vegetation investigation included all together 80 different species. This material was processed numerically by using multivariate methods. Indirect gradient analyses were performed using Detrended Correspondence Analysis (DCA) and Local Nonmetric Multidimentional Scaling (LNMDS). Direct gradient analyses were performed by using rescaled hybrid Canonical Correspondence Analysis (CCA). Non-parametric correlation analyses, Kendall’s , were performed between environmental parameters and DCA axis values. The results of the numerical and statistical processing were used partly to provide a description of the vegetational structure in the material and partly to quantify how much each ecological parameters contributed to determination of vegetational structure. This work shows the species distribution along various complex gradients; moisture, nutrient conditions, light etc. The investigation is primarily designed to study vegetation dynamics along these gradients and whether changes in the number of species can be related to changes in physical, biotic and, not least, chemical parameters. Variance analysis was performed to assess to what extent the sample plots tends move in a determined direction from 1990 to 1995. The variation between the years were not significant along the primary complex gradients, but there were a significant displacement of species along the following gradients. The most important species were: Vaccinium vitis-idaea, Melampyrum sylvaticum and Hylocomium splendens), which showed an increase and some cryptogams like Brachythecium reflexum, B. salebrosum and Cladonia ecmocyna which declined.

10. Monitoring terrestrial ecosystems: Ecological investigation of vegetation in the boreal birch forest of Dividalen National park, county Troms, Norway.

In 1993, the Directorate for Nature Management (DN) established a new area for the monitoring of terrestrial ecosystems in Dividalen National Park in Troms County. This report presents the reanalysis of vegetation and soil from this terrestrial monitoring area. The area in Dividalen is located in the northern boreal birch forest, in a relatively continental section where the dominant type of vegetation is bilberry-mountain crowberry birch forest (A4c). The structure of the vegetation is analysed by multivariate methods (ordination). In Dividalen all together 131 species were found; 75 vascular plants, 18 mosses, 14 liverworts and 24 lichens. This is a decrease from the number of species recorded in 1993 when 141 species were found in the same mesoplots: 74 vascular plants, 24 mosses, 18 liverworts and 25 lichens. The decrease was not significant for the total number of species or for the total number of vascular plants. However the total number of cryptogames showed a slight significant decrease in number between 1993 and 1998. This may be due to increased cover of several ericoid species. In Dividalen we found no significant changes in vegetation composition for the periode 1993 – 1998 along the first four ordination axes. However, there were changes in mesoplots with high DCA1 values. The changes were in the direction towards lower species richness. Species like Myosotis decumbens, Poa alpina, Solidago virgaurea, Cerastium fontanum and Rumex acetosa ssp. lapponicus showed the largest decrease in these mesoplots. Species that showed the largest increase were Vaccinium vitis-idaea, Mnium spinosum and Polytrichum juniperinum. We have found no relations between these changes and acidification due to deposition of pollutans. Lack of disturbance factors in the area in the last years, which favours an increase in ericoid vegetation, is the probable explanation for the changes.
