To distinguish between atmospheric and marine transport of contaminants to northen latitudes by comparison inventories of lake and fjordic sediments.
To investigate arctic foxes physiological adaptations to life at high latitudes. Resting and running metabolic rates, body weight, food intake, body core temperature, heart rate, and blood parameters were examined during different seasons and during periods of food deprivation.
Biological nitrogen fixation by cyanobacteria is a key process for productivity in terrestrial Arctic ecosystems and the activity is dependent of size and diversity of cyanobacterial populations. Changes in biodiversity after pertubations of different types of habitats simulating climatic changes or other antropogenic effects will be studied by molecular methods and correlated to variations of nitrogen fixation activity.
Monitoring of the active layer near Ny Ålesund as part of the international monitoring scheme CALM (Circumpolar Active Layer Monitoring)
The structure and role of the cyanobacterial communities that colonise bare soils and fix nitrogen in the arctic ecosystem will be studied. The planned activities will focus on the isolation, identification and characterisation of cyanobacteria from arctic habitats and on the changes of the cyanobacterial community along a transect from a retreating glacier front to a more stable habitat characterised by the presence of mature vegetation. For these purposes, a polyphasic approach encompassing microbiological, morphological and molecular techniques will be applied to environmental samples and isolated cultures. The obtained results will give new insights on the diversity and role of nitrogen fixing cyanobacteria in the arctic and, in more general terms, on ecosystem development under changing climatic conditions.
Estimation of gravity around Ny-Ålesund
To evaluate temporal variation in arctic fox numbers and their food resourses in the Kongsfjorden area. The number of foxes captured per 100 trap-days are used as an index of fox density termed "Fox Capture Index". The observations of denning activity i.e. observation of number of arctic fox litters and litter size at den are termed "Fox Den Index" as a second index of fox abundance. A third index is termed "Fox Observation Index". This index is based on both observations of adult foxes seen away from breeding dens pr 100 h field work and reports on request from scientists and local people on observations of adult foxes during summer. In addition, reports on observation of fox tracks in the study area were collected in 1990-2001 as a fourth index, which were called "Fox Track Index". The field census are conducted for 10 days starting at the end of June. All dead foxes in the area should be collected.
The main focus of our project is to study the onset of summer melt conditions in terms of the surface energy budget over fast ice and ints impact on the formation of superimposed ice.
The determination of radionuclide levels, their temporal and spatial variations and investigations concerning Arctic-specfic processes providing insight into radionuclide behaviour in the extreme environments and long-range transport of contaminants to Svalbard.
Surveillance of sea birds, west Spitsbergen
Effects of POPs on the immune system in the glaucous gulls
The aim of this programme will be to study the mechanisms of the regulation of the body fuel utilizon and energy expenditure during fasting
The objective is to monitor the Svalbard reindeer population at Brøggerhalvøya.
Estimate the vertical distribution of glacierice along the west coast of Svalbard during the last iceage.
Parental effort, the extra energy expenditure above maintenance levels devoted to the care of affspring, has been postulated to incur a fitness cost.
Part of the international project Arctic Costal Dynamics (ACD) were Department of Physical Geography, University of Oslo participates. The working group consists of Trond Eiken (UoO), Bjørn Wangensteen (UoO) and Rune Ødegård (Gjøvik University College). The aim of this part of the ACD-project is to quantify coastal cliff erosion by the use of terrestrial photogrammetry.

Monitoring solar wind-magnetosphere-ionosphere coupling processes from the aurora.
The general objective of the proposed project is to increase the understanding of the Mercury Depetion Events occoring in the Arctic sunrise and quntify the input of mercury to polar ecosystems during this events.
