121. AMAP 2009 and 2010 core HM and POP programme Faroe Islands

The project is a continuation of the monitoring activities of the AMAP POPs and Heavy metals programme in marine, terrestrial and freshwater environments of the Faroe Islands. The aims of the programme is to establish data for timetrend and spatial assessments as well as providing data of importance in human health risk assessment on mercury and POPs. The programme incorporates analyses on pilot whale, cod, black guillemots from the marine environment, sheep and hare from the terrestrial environment and arctic char from the freshwater environment. The compounds analysed are "legacy" POPs and mercury, cadmium and selenium. In addition, a retrospective analyses of PFOS in pilot whale tissues going back as far as possible (ie.1986) is part of the project.

122. Contaminants in Polar Regions – Dynamic Range of Contaminants in Polar Marine Ecosystems (COPOL)

The IPY-project ‘COPOL’ has a main objective of understanding the dynamic range of man-made contaminants in marine ecosystems of polar regions, in order to better predict how possible future climate change will be reflected in levels and effects at higher trophic levels. This aim will be addressed by 4 integrated work packages covering the scopes of 1) food web contaminant exposure and flux, 2) transfer to higher trophic levels and potential effects, 3) chemical analyses and screening, 4) synthesis and integration. To study the relations between climate and environmental contaminants within a project period of four years, a “location-substitutes-time”-approach will be employed. The sampling is focussed towards specific areas in the Arctic, representing different climatic conditions. Two areas that are influenced differently by different water masses are chosen; the Kongsfjord on the West-coast of Spitzbergen (79N, 12 E) and the Rijpfjord North-East of Svalbard (80N, 22 E). The main effort is concentrated in the Kongsfjord. This fjord has been identified as particularly suitable as a study site of contaminants processes, due to the remoteness of sources, and for influences of climatic changes, due to the documented relation between Atlantic water influx and the climatic index North Atlantic Oscillation (NAO). The water masses of the Rijpfjord have Arctic origin and serves as a strictly Arctic reference. Variable Atlantic water influx will not only influence abiotic contaminant exposure, but also food web structure, food quality and energy pathways, as different water masses carry different phyto- and zooplankton assemblages. This may affect the flux of contaminants through the food web to high trophic level predators such as seabirds and seals, due to altered food quality and energy pathways.

123. From Soil to Ocean: Transfer of terrigenous organic carbon from permafrost soils to the Arctic Ocean

In order to estimate the effect of rising global temperatures on organic carbon (OC) stocks in the temperature-sensitivity Arctic environment, our project aims at investigating the transfer of terrestrial OC from permafrost soils to the Arctic Ocean. Detailed compositional analyses of bulk soil and sediments along a transport trajectory combined with compound-specific isotopic (13C and 14C) analysis of selected lipid biomarkers will be used to study alteration processes of organic matter occurring in the soil and its during transport. Sub-goals include to a) identify suitable biomarkers for soil organic carbon in permafrost soils, b) determine residence times of selected biomarkers in permafrost soils, fluvial and marine sediments, and c) quantify carbon transfer from source (soil) to sink (marine sediment) and its timescale.

124. Haliclona natural products

In contrast to many other marine regions, chemical interactions between organisms in Arctic waters are little understood. This project investigates natural products and chemical interactions in the sponge genus Haliclona in temperate and polar waters. Several new secondary metabolites isolated from Haliclona show feeding deterrence and activity against bacteria and fungi, but the compound composition varies with habitat and year. That raises the question whether sponges of the genus Haliclona as a model are able to adapt to changing environmental factors such as water temperature and colonization by bacteria by varying their secondary metabolite composition.

125. Biology of Arctic macroalgae

The effects of stratospheric ozone depletion and of global warming on the marine biosphere are still underexplored, especially in the Arctic. Seaweeds are very important primary producers but are strongly susceptible to enhanced UV radiation and elevated temperatures, especially their spores. The UV susceptibility of spores has previously been invoked to determine the depth distribution of seaweeds. Therefore, we will investigate the effect of different radiation and temperature conditions on the ultra-structure, physiology and biochemistry of spores from various brown and green algae growing in different water depths. Moreover, we will study competition between zoospores of various species of brown macroalgae in order to get an insight about biotic factors structuring seaweed communities and also to explain more clearly the present seaweed zonation pattern.

126. Occurence of "new" contaminants in marine biota in Greenland and the Faroe Islands

In addition to the persistent organic pollutants (POPs) analysed in former monitoring projects, other compounds of concern have been identified by the international community (e.g. OSPAR, AMAP), and analytical methods have been developed. These compounds include brominated flame retardants (BFRs), phthalates, polychlorinated naphthalenes (PCNs), perfluorooctane sulfonate (PFOS) and synthetic musk compounds. The aim of this project is to screen the marine environment of East and West Greenland and the Faroe Islands for these compounds. The analyses will be based on existing samples of pilot whale and fulmars from the Faroe Islands as well as marine sediments, shorthorn sculpins, ringed seals, minke whales from West Greenland and shorthorn sculpins, ringed seals and polar bears from East Greenland. As several trophic levels of the marine Arctic food chain are taken into account, the project will also result in information on the bioaccumulation of these compounds.

127. AMAP Oil assessment

AMAP has decided to prepare an assessment of the environmental impacts of oil and gas developments in the Arctic and of pollution by petroleum hydrocarbons. The assessment is planned to be ready in 2006. NERI will co-ordinate the Danish/Greenlandic contribution.

128. Contaminants in polar bears

Polar bears are at the top of the arctic marine food chain. Owing to the high lipid content of their diet, polar bears appear particularly prone to bioaccumulate organochlorines. Polar bears from East Greenland and Svalbard have higher contaminant levels than polar bears elsewhere in the Arctic. Levels of PCBs in these areas might negatively affect reproduction and survival. So far more than 130 polar bear samples have been collected since 1999. These samples are being analysed for organochlorines and pathological effects.

131. A simple model of transfer of atmospheric mercury to carnivores

The present study will establish a link between the mercury levels in the abiotic environment (e.g. historical records of mercury data in peat bogs, the ice sheet or marine sediments) with levels in carnivore species (polar bear, birds of prey). These results can be used in a model for predicting past and future development of the mercury loads in high trophic biota. This in turn will enable us to evaluate if changes in mercury levels in the atmosphere are reflected in species at higher trophic levels of the Arctic ecosystem. The project will expand the longevity and certainty of the biotic time series of mercury to about 150 years by analyzing museum samples of bird feathers and polar bear hair and teeth. The project is part of the project “Fate of mercury in the Arctic (FOMA)”.

133. 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).

135. 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.

136. Effects of UV radiation on lipids, fatty acids and nutritional quality of Arctic marine algae and zooplankton

This project investigates how solar UV radiation affects planktonic food webs in the Arctic by changing the nutritional quality of the lower trophic levels. UV radiation has been documented to lead to oxidation of poly-unsaturated fatty acids (PUFAs) in phytoplankton. These PUFAs cannot be synthesized de novo by zooplankton, but are key molecules for the marine pelagic food web. A combined approach was chosen with both sampling of field data (physical as well as biological) and experiments which were carried out during two field seasons in Ny Ålesund in 2003 (april/may) and 2004 (may/june). In 2004, the main part of the field work consisted of an outdoor experiment where phytoplankton was exposed to different irradiation regimes, using the natural sunlight. Algae from all different treatments were used for feeding zooplankton in order to trace the transfer of irradiation-induced changes of the fatty acid composition in phytoplankton to the next trophic level. A number of additional parameters will be analysed as well, combined with the results of an extensive measurement series of both PAR- and UV light. The experiment was carried out on the old pier (Gamle Kaia), while the laboratory part took place in the Italian station ‘Dirigibile Italia’.

137. Environmental effects of offshore oil activities: experimental tests of petroleum-associated components on benthos at community, individual, and cellular levels

This project will examine benthic processes in arctic and mid-latitude regions in order to derive specific conclusions on the sensitivity of benthic organisms and communities to acute spills of petroleum-related chemicals and routine releases of drill cuttings. We will carry out a series of controlled experiments on whole sediment communities and individual benthic organisms with additions of drill cuttings and petroleum-associated contaminants, arriving at a set of hypotheses on the likely impacts on the benthos of petroleum production activities at higher latitudes. A series of testable hypotheses will be formulated based on an examination of real-world monitoring data sets collected under Norway’s Petroleum Regional Monitoring Programme and results of mesocosm experiments performed previously at the Norwegian Institute for Water Research (NIVA) Station at Solbergstrand. These data sets will be examined in order to identify the geographic scope of responses to petroleum industrial activities. Through this work, we intend to propose procedures to improve the interpretation of benthic monitoring data for diverse environmental regions in Norway. The project is linked to several on-going NFR projects within the Polarklima programme. By involving a Ph.D. student the project will advance the education and training of young scientists in the field of biological effects studies related to petroleum development and exploration activities.

138. Behavioral and evolutionary implications of strict monogamy. An experimental approach in panarctic seagull: the black-legged kittiwake Rissa tridactyla breeding in Alaska

This project's goal is to experimentally study strict monogamy in a panarctic seagull, the black-legged kittiwake, in Alaska. It studies mate choice (which is crucial because no mixed strategy is used) in relation to indivdual quality, fitness and sexual conflict in strictly monogamous species. It is rooted in a detailed knowledge of the species’ biology and the merging of three teams (French, Austiran and Alaskan) with long-term experience researching kittiwakes. It uses the unique experimental Alaskan setting for wild populations.

139. Interactions between meiofauna and mat-forming microbes at the sediment-water interface - implications for benthic-pelagic coupling in coastal systems

The project investigated small-scale biotic interactions between laminated microbial communities and meiofauna at light-exposed sediment-water boundaries of estuarine lagoons. The production and biological structure of these systems is mainly determined by complex processes at the sediment-water interface which depend on finely scaled patterns, requiring appreciation of how the biota interact within these scales. We tested whether changing light conditions and active emergence of the harpacticoid species Mesochra lilljeborgi and Tachidius discipes are mediated by the activity of benthic oxygenic and anoxygenic phototrophic microbes. Two hypotheses were tested which addresses to the question of causality between changing light conditions and active emergence of the harpacticoid copepods. (1)The harpacticoid copepods T. discipes and M. lilljeborgi will enter the bottom water during daylight when oxygenic photosynthesis of cyanobacteria and eukaryotic algae is blocked and conditions at the sediment-water interface have turned anoxic. (2)Both species will not emerge during dark exposures when transferred to sterilized sediments.
