The study aims to optimise the used of landscape data as satellite images, aerial photos, maps, weather data when assessing conditions contributing to accidental risks. So far the study has focused on slope processes along the railway between Kiruna and Riksgränsen (Norwegian border).

The pressure on the ecosystems of the mountains of northern Sweden has increased over the last hundred years as a result of, for example, hydropower and infrastucture development, mining and tourism. This paper discusses the impacts of a highway project between Kiruna and Riksgränsen, in a sensitive mountain area in northernmost Sweden. The study has a holistic and dynamic approach including components from bio-, earth- and social sciences. The project was carried out in three stages; the first covering the construction period between 1978-1984, the second 1985-1989 and the third from 1990-1997 describing the long term impact after the opening of the road. The studies include the monitoring of the water environment, vegetation changes, air pollution, wear, outdoor recreation, economic development, land use changes etc. The main result show that environmental impact decreased rapidly after the period of road construction. On the other hand, human activities were not greatly affected during the construction phase, but after the road was opened the number of visitors to the area increased for a few years. We could also observe increased secondary effects, such as land use changes and new construction stimulated by the opening of the road.

The Submarine Operational And Research Environmental Database (SOARED)is comprised of a fixed relational environmental database using unclassified data collected during the Science Ice Exercises (SCICEX) during the past several years. It also includes publicly accessible gridded historical sound velocity, temperature and salinity data from 1900 from the US National Oceanographic Data Center. This project is a demonstration system to show ways to retrieve and analyze sound velocity, temperature and salinity profiles, bathymetry and ice thickness data using a mouse-driven GIS-based query.

Examine temporal and spatial variation in trace metal concentrations in the western Arctic through the analysis of Black Guillemot feathers. Temporal trends being examined using study skins collected as early as 1897. Spatial variation examined in conjunction with carbon isotope signatures in feathers and by sampling both winter and summer plumages. Regional climate change monitored through examination of annual variation in breeding chronology and success in relation to snow and ice melt.

A proposal has been submitted to the National Science Foundation titled: For Support of the Arctic Social Science Data Center at NSIDC, OPP-0119836.

Contaminants were examined for trends over time, spatial variation based on disparate breeding areas, and relationships with measures of productivity. Most organochlorines and metals declined over time. Mercury was the only contaminant with possibly increasing concentrations in eggs. Egg and feather samples collected in 2000 will provide more information on mercury trends and effects. This study embodies 20 years of data on environmental contaminants in peregrine falcons nesting in Alaska.

The aim of the project is to use Strontium isotopic ratios in bone and feather tissue to discriminate between the two races of redshank (Tringa totanus)that overwinter on Scottish estuaries. One race brittanica breeds in Scotland and the other, robusta breeds in Iceland. Preliminary results have shown there to be two distinct clusters of ratios for the two races enabling the racial identification of juvenile birds. It is planned to extend the study to develop other migratory tracing methods for shorebirds and wildfowl using European estuaries.

The overall project outlined in this proposal represents a series of interrelated studies designed to answer questions regarding the effects of disturbance on distribution and abundance of waterfowl and marine birds. The primary studies (i.e., aerial surveys) are directly related to the objectives identified in the Minerals Management Service (MMS) Statement-of-work regarding Monitoring Beaufort Sea Waterfowl and Marine Birds near the Prudhoe Bay Oil Field, Alaska. Additionally, we plan to include the ‘optional’ studies on eiders using off-shore barrier island habitats. Finally, we propose to conduct ground based studies designed to enhance and expand the interpretation of the aerial surveys. The specific objectives of this study are: 1. Monitor Long-tailed Duck and other species within and among industrial and control areas in a manner that will allow comparison with earlier aerial surveys using Johnson and Gazeys’ (1992) study design. a) Perform replicate aerial surveys of five previously established transects based on existing protocol (OCS-MMS 92-0060). b) Expand the area from original surveys to include near-shore areas along Beaufort Sea coastline between the original “industrial” (Jones-Return Islands) and “control” (Stockton-Maguire-Flaxman Islands) areas. c) Define the range of variation for area waterfowl and marine bird populations. Correlate this variation with environmental factors and oil and gas exploration, development, and production activities. 2. Expand aerial monitoring approximately 50 km offshore. Surveys will target Spectacled, Common and King eiders. The goal is to sample areas potentially impacted by oil spills from the Liberty, Northstar, and/or Sandpiper Units. 3. Develop a monitoring protocol for birds breeding on barrier islands, particularly Common Eiders. These data will be compared to historic data summarized by Schamel (1977) and Moitoret (1998). 4. Examine relationships between life-history parameters (e.g., fidelity, annual survival, productivity) and ranges of variation in Long-tailed Ducks and Common Eider distribution and abundance to enhance interpretation of cross-seasonal effects of disturbance. That is, the combination of aerial and ground based work has the potential to both document changes in abundance/distribution and describe those changes in terms of movements of marked individuals. Parameters will be examined in relation to disturbance using the two-tiered approach developed by Johnson and Gazey (1992). 5. Recommend cost-effective and feasible options for future monitoring programs to evaluate numbers and species of birds potentially impacted by oil spills involving ice-free and ice periods in both inshore and offshore waters.

The aim is to monitor the Lake Myvatn and the river Laxá ecosystem for (1) detecting trends, (2) detecting background variability in the system, (3) assess the efficiency of management measures, (4) observe perturbations in order to generate hypotheses about causal relationships.

The Collaborative Interdisciplinary Cryospheric Experiment (C-ICE) is a multi-year field experiment that incorporates many individual projects, each with autonomous goals and objectives. The science conducted has directly evolved from research relating to one of four general themes: i. sea ice energy balance; ii. numerical modeling of atmospheric processes; iii. remote sensing of snow covered sea ice; and iv. ecosystem studies.

Persistent organic pollution is a global problem. This fact is especially apparent in the Arctic where pesticides currently used in distant environments accumulate, in some cases to higher levels than those observed in the source region. This pollution threatens the well-being of the aboriginal inhabitants of these regions. Most of the traditionally harvested animals in the Arctic are long-lived and from the higher trophic levels of the food chain, thereby providing an opportunity for considerable bioaccumulation and biomagnification of persistent contaminants. This has prompted a growing concern by the Alaska Inupiat that pollutants in the environment might be contributing to their unique morbidity and mortality rates, especially of their children. Our studies are currently focused on two specific organic pollutants found in the Arctic environment; 1}hexachlorobenzene (HCB), a byproduct during manufacture of several different chlorinated compounds and consistently detected in the Arctic and, 2} dichlorodiphenyl dichloroethylene (p,p’-DDE), a chlorinated environmental breakdown product measured in the Arctic population at significantly higher concentrations than the parent pesticide, DDT. We hypothesize that mammalian embryonic cell exposure to these chemicals, individually or as mixtures at environmentally relevant concentrations and ratios, will alter the cell cycle and/or cause death by apoptosis, rather than by necrosis. We also predict synergistic cytotoxicity of the chemical mixture because of an accumulation of deleterious effects at different cellular target sites by each chemical. We further hypothesize that while some chemicals target non-genetic cellular components (such as a cell membrane or cytosolic component), other chemical effects will occur primarily at the genetic level, directly or indirectly. Our experiments have been designed as a set of sensitive cellular and molecular assays to compare levels and types of cytotoxic and genotoxic activity of the above chemicals (individual and mixture), at environmentally relevant concentrations, upon embryonic cells in culture. Our experimental evidence thus far is that these chemicals, separately or as a mixture at concentrations and molar ratios relevant to that measured in the Arctic environment, do have cytotoxic and/or genotoxic effects that could result in profound consequences to exposed tissues of a developing embryo or fetus. We have further experimental evidence that exposure to both chemicals at environmentally relevant concentrations is more toxic to the cell than the sum of effects by exposure to the individual chemicals. Experimental results indicate this is due to different cellular target sites for each chemical (Appendix A: Preliminary Results).

Biological materials obtained in the central Arctic Ocean at the FSU “North Pole stations” in 1975-1981 have shown that the multi-year ice and ice/water interface is of rich and diverse biotop inhabited by the large number of diatoms and invertebrate animals. Two main matter fluxes in the sea ice ecosystem may be distinguished: (1) the inflow of biogenous elements from water into the ice interior where they are assimilated by the microflora during photosynthesis (summer stage), and (2) the outflow – from ice to water - of the organic matter accumulated in the summer due to photosynthesis (winter stage). Accumulation of organic matter within the sea ice interior during the process of photosynthesis may be considered as an energy depot for organisms of the whole trophic network of the arctic sea ice ecosystem. Recent data from the SHEBA Ice Camp drifted within the Beaufort Gyre 1997-1998 have shown that: (1) sea ice diatoms are very scarce by species and numbers; (2) fresh water green algae are dominated by numbers and distributed within the whole sea ice thickness; (3) invertebrate animals within the sea ice interior are not indicated; (4) invertebrate animals from the ice/water interface are scarce by species and numbers; (5) concentrations of chlorophyll and nutrients in the sea ice are significantly lower of the average concentrations measured before in this region for the same period of time. Remarkable accumulation of the organic mater within the sea ice interior were not indicated.

We compared animals from a caribou (Rangifer tarandus) mortality event in the area of Point Hope and Chariot (Cape Thompson), Alaska (USA) in 1995 to hunter-killed caribou from reference sites (Barrow, Red Dog Mine, and Teshekpuk Lake, Alaska). Gross and histologic endpoints, and element levels (As, Cd, Cu, Pb, Zn, Fe) were evaluated. Starvation/malnutrition were major factors leading to death or severe weakness as very little or no fat (very low body condition scores) and serous atrophy of fat (marrow cavity and histologically) were more prevalent in caribou associated with the mortality event as compared to reference sites animals. Accumulation of hepatic hemosiderin in Kuppfer cells was noted as an indicator of cachexia. Levels of lead in feces and liver, copper the rumen contents, and arsenic in muscle were higher in caribou harvested near Red Dog Mine and might be expected in the mineral rich area, but were not at a level of concern for toxicoses. Kidney levels of cadmium were significantly increased with increasing age, and presents a potential concern for human consumers, and is an expected finding. We concluded that heavy metals played no role in the mortality event and that caribou starved. Further investigation of regional minerals differences is required to understand the sources and transport mechanisms to explain these findings and to properly address mining activity impacts. Mortality events on the north slope of Alaska are not uncommon and likely involve starvation as described here, but in most cases are not investigated, even though recent industrial activities have heightened concern.

The aim of the study is to make a first integrated assessment of environmental and socio-economic aspects of the northern Russian coastal region, in this case the sub-Arctic White Sea and Arctic Pechora Sea, on the basis of 1) the present state of the coastal environment, as based on the results of INTAS project 94-391, and 2) the sociocultural and economic significance of those regions, and the present and potential conflict situations between, and developmental potentials of, environmental and local socio-economic aspects. Research activities: Inventory and literature search on socio-economic and environmental aspects in White Sea, southern Barents Sea and Pechora Sea.

The objectives of the project are to assess: 1) the present biodiversity of benthos in Arctic coastal ecosystems (White Sea, southern Barents Sea, Pechora Sea), and indicators for changes caused by disturbances; 2) the adaptations to the Arctic climate for some benthic key-species, the additional influence of disturbance and the sensitivity of the key-species to additional stress from disturbances; 3) the geochemical background of the regions Research activities: Annual missions by ship for sampling water, sediments and macrobenthos. Biodiversity analysis of macrobenthos in sediments in laboratories in Murmansk (MMBI) and Tromsø (Akvaplan-Niva), ecophysiological analyses in laboratories of St. Petersburg (ZISP), Yerseke (NIOO-CEMO) and Pisa (UN), analyses of pollutants in laboratories in Moscow (MSU), Nantes(UN) and Pisa (UP), geochemical analyses of water and sediment in laboratories of Moscow (MSU) and Barcelona (UB).

This study aims at reconstructing the Barents Sea marine ecosystem before the exploitation by man. This reconstruction will be made by using the existing archival resources on catch statistics from the 17th to 19th centuries in the Netherlands, Germany, Denmark and the United Kingdom, in combination with the present knowledge an animal behaviour and food web structure. Fieldwork is planned in two former hunting areas in Spitsbergen: the Smeerenburgfjord and the Storfjord to study both the structure of the recent marine ecosystem and the composition, size and dating of the recent bird rookeries. This information in combination with the historical data will be used to reconstruct the original ecosystem.
