1. LAPBIAT-Lapland Atmosphere-Biosphere facility

The main objective of the facility is to enhance the international scientific co-operation at the seven Finnish research stations and to offer a very attractive and unique place for multidisciplinary environmental and atmospheric research in the most arctic region of the European Union. Factors such as, arctic-subarctic and alpine-subalpine environment, northern populations, arctic winters with snow, changes in the Earth's electromagnetic environment due to external disturbances and exceptionally long series of observations of many ecological and atmospheric variables should interest new users.

3. Marine corrosion of stainless steel in Polar seawater

The effects of biofilm settlement on corrosion resistance of stainless steels in polar seawaters are not well known. In warmer conditions (Mediterranean sea) biofilm increases both the risk of localised corrosion onset and the propagation rate of corrosion attack. Corrosion tests carried out in Antarctica demonstrated that biofilm growth at about 0°C induced electrochemical effects less important than those occurring in warmer conditions. On the contrary, corrosion tests performed in similar environmental conditions at Ny-Aalesund (Svalbard) showed more severe corrosion attack than in Antarctica. This research aims: - to define the influence of biofilm on stainless steel corrosion resistance in polar seawater in the range of temperature between -1 and +5 °C, - to define if change in salinity can influence corrosion process, - to identify stainless steel grades which can be acceptable in such conditions (polar seawater seems to be somewhat less corrosive, which gives the possibility to use cheaper stainless steels).

5. Long-term effects of offshore discharges on cold water zooplankton: establishing a test system for chronic exposure to offshore discharges

During the last decade the concern regarding environmental effects of the offshore industry has shifted from effects of drilling discharges on benthic communities, towards a stronger focus on the water column and effects on the pelagic ecosystem. At the same time, oil and gas development is expanding in the Norwegian and Russian sectors of the Barents Sea. In this regard, a project has been initiated to look at responses of especially Calanus spp. and other copepod species to long-term, sublethal exposure to selected offshore discharges and discharge components, as well as accidental oil spills. Calanus spp. is ecologically the most important zooplankton species along the Norwegian shelf and in the Barents Sea. A laboratory based facility for culture through several generations is being developed through this project. In addition, the impact of oil compounds on the cold-water and arctic Calanus species-complex will be examined by carrying out a series of laboratory (some at Ny Ålesund) and ship based experiments. The response parameters will include both behavioral (feeding, mate finding, avoidance) and physiological (mortality, egg production, development rates, oxygen consumption and assimilation efficiency) parameters. The ultimate outcome of this research is expected to be a supporting instrument for ecological risk assessment of offshore discharges, which is highly relevant both to the North Sea, the mid-Norway shelf and the Barents Sea.

6. The Effect of solar UV on lipids in the planktonic food chain of polar freshwater ponds

Plankton of shallow polar freshwater water bodies is exposed to increasing levels of ultraviolet radiation (UVR) due to the limited water depth. Daphnia (Crustacea, waterflea) and algae are common representatives of the food chain in these water bodies. Daphnia almost exclusively use lipids for energy storage, which they obtain from their food (mainly algae). Therefore, Daphnia and algae are closely linked to each other. Preliminary experiments on the UV-induced damage in phyto- and zooplankton point to lipids as one of the key players. With this application we want to identify how algae specific lipids and fatty acids (FA) are modified by UVR. The factors modifying UV-doses to the animals and their food are depth of the waterbody and DOC (absorbs UV). A pondsurvey shall provide a wide spectrum on ponds which vary in DOC and depth. Lipid analysis of Daphnia and their food of these ponds as well as physical parameters of the pond waters shall identify correlations between UV-exposure and specific fatty acids. This shall enable us to estimate the effect of solar UVR on the freshwater plankton community in polar ponds.

7. Determination of cloud coverage and radiative forcing from surface measurements

Specific objectives of the proposal are: 1. the determination of the cloud coverage by means of a simple methodology based on radiometric measurements; 2. the determination of the radiative forcing produced by different type of cloud and coverage for applications into GCM’s as ‘cloud parameterisations’. The results will be obtained for two different radiative regimes by means of different experimental campaigns.

8. Bioaccumulation, physiological and biochemical effects of pollutants in mussels

In order to evaluate the capacity of mussels to accumulate pollutants and to enhance growth and physiological effects, an investigation was carried out in the Faroe Islands and in the Skagerrak. In March 2000, about 1500 mussels of proper dimensions (length ranging between 5 and 6 cm) were collected in the Kaldbak Fjord (Faroe Islands) on a 10m water column. Selected mussels were divided in 4 groups (320 each) and deployed in 4 different stations (one at the Faroe Islands and three in the Skagerrak). Semipermeable membrane devices (SPMDs) were also deployed in the same stations for the preconcentration of lipophilic pollutants. One month later (end of April-beginning of May) mussels and SPMDs were recollected and sent to different laboratories for the determination of various parameters.

15. Effects of UV-radiation on macroalgae of the Kongsfjorden

Photoinhibition of photosynthesis by UV radiation, the formation of UV-screening pigments, DNA damage by UV radiation as well as DNA repair mechanisms will be determined in marine macroalgae of the Kongsfjord. Moreover, algae from different water depths will be transplanted by divers into areas with opposite light climate or covered by UV-screening filters and their physiological reactions tested. Additionally, the susceptability of the unicellular algal spores to UV-radiation will be tested. The results will allow insights into the effect of UV and photosynthetically active radiation on the zonation of macrocalgae and on the structure of phytobenthic communities. The data will be used to model the effects of increased of UV-radiation due to stratospheric ozone depletion on the Kongsfjord phytobenthic communities.

16. Effects of UV radiation on growth and recruitment of macroalgae: implications for vertical zonation of macroalgae across a latitudinal gradient

This study will be designed to determine the response mechanisms of representative species of macrophytes along the tide flat to provide the physiological basis for answers for ecological questions, in particular how the community structure of various beds of macroalgae from the intertidal to the subtidal (eulittoral to sublittoral) region of the coastal ecosystem is affected by enhanced UV radiation. In situ measurement of photosynthetic efficiency, growth, community structure and succession will be conducted to investigate how do different species of macrophytes respond to changes in the light environment over a depth gradient and across seasons of the year. It is hypothesized that the differences in the ability to tolerate stress are the main factors controlling the distribution pattern of macrophytes. With the limited understanding in the control of tolerance, elucidating the mechanism of stress in the physiology and ecology of the organisms will allow us to quantify the impediments encountered by organisms inhabiting the tide flats. Objectives: 1. To measure the daily and seasonal variation in photosynthetically active and ultraviolet radiation. 2. To characterize the macrophyte community structure of the coastal habitat. 3. To perform UV exclusion and UV supplementation experiments in order to assess its effect on the growth of some macrophyte species in the field and in mesocosms. 4. To assess the prevention of UV damage in selected macroalgae by production of sunscreen pigments. 4. To determine the recruitment rate, recolonization pattern and succession under PAR and varying UVR condition.
