1. Restoration of the salmon stock in the Tuloma river system

The possibility of restoring the salmon stocks in the Tuloma system is assessed by collecting background information on the river system: present fish fauna, habitat quality, migratory routes etc. Planning the restoration including technical and management aspects is under way.

2. Monitoring of the Atlantic salmon stocks of the Teno (Tana) and Näätämö (Neidenelva) river systems, northernmost Fennoscandia.

Monitoring of the salmon stocksof the Teno and Näätämö river systems is based on long term data collection on juvenile salmon production, biological characteristics of the spawning stock, origin of salmon (wild/reared) and statistics on fishery and catches. Information on other fish species than salmon is also available.

4. Arctic Oceanographic Observations (AREX) (AREX)

Since 1988 the regular summer hydrographic observations in the Nordic Seas and Fram Strait have been collected by the Institute of Oceanology Polish Academy of Sciences (IOPAS). Observational activities were carried out under several national programs, in the frames of EU projects VEINS, ASOF-N and DAMOCLES and within Polish-Norwegian cooperation in the AWAKE project. The main objectives are:  to study the long-term variability of water mass distribution, their physical and chemical properties and different pathways in the Nordic Seas;  to investigate the Atlantic water (AW) circulation in the Nordic Seas and its inflow into the Arctic Ocean;  to recognize the possible feedbacks between the Atlantic water variability and local and global climate changes.

5. Hydrology and water currents in the inner part of Kongsfjord in front of Kongsbreen Glacier

The aim of this project is to study the physical oceanography of the sea in the area where Kongsbreen glacier get in touch with the sea in the inner part of Kongsfjord. In particular the project aims:  to characterise temperature and salinity of water masses in the inner part of Kongsfjord close to Kongsbreen Glacier  to characterise major fresh water outflow from Kongsbreen glaciers to the sea in the inner part of the fiord  to collect time series if seawater currents in-out from the inner part, temperature and salinity patterns for one year from summer 2001 to summer 2002.  to collect a one year time series of sea level changes by an automatic self recording depth gauges deployed close to the base.

6. Role of organic and inorganic particles in the mobility of radionuclides in the Kongsfjord-Krossfjord system (MORAK)

The aims of the project are: - to evaluate the fluxes of radionuclides in the water column and their accumulation in the sediment, on a short-time scale; - to determine the C/N and delta13C-delta15N ratios in suspended and sedimentary matter, and test their use as tracers of origin, composition and transformation pathways of organic particles. The selected study area is the Kongsfjord-Krossfjord system, Svalbard, considered as representative test-site for studying processes occurring in Arctic fjords. The focus of the project will be on the processes occurring at the glacier-sea interface, where enhanced lithogenic and biogenic particle fluxes are reported in summer. Specific methods will be used to trace the particle sources. The rate of accumulation-resuspension processes will also be investigated from the inner fjord to the outer continental shelf.

7. Relative importance of different sources of particulate matter in the Kongsfjorden environment

The general objective of this research concerns the quantitative and qualitative study of particulate matter retained in natural (sea-ice and sediment) and artificial (sediment traps) traps in order to determine the main origin (autochtonous and allochtonous) and the relative importance of different fractions of particulate matter and to follow their fate in the environment. To quantify the autochtonous origin of particulate matter, primary production, nutrient uptake, biomass distribution, phytoplankton community structure and fluxes in the first levels of the trophic chain will be investigated. Studies will be conducted in the sea-ice environment and in the water column and compared to the particle fluxes measured both in the water, using sediment traps and in the sediment, by radiometric chronology, in order to estimate the different contribution of these habitats to carbon export to the bottom. The zooplankton will be identified and counted and primary production, nutrient uptake and phytoplankton dynamics will be related to hydrological structure and nutrient availability in the environment. The Kongsfjord results particularly suitable for the main objective of this research as it is influenced by important inputs of both atmospheric (eolic and meteroric) and glacial origin and is characterised by a complex hydrological situation which may promote autochtonous productive processes, thus determining important particulate fluxes.

8. Submarine Operational And Research Environmental Database (SOARED)

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.

13. The high latitude oceans in the climate system, with special emphasis on their role in the global carbon cycle

The scientific objectives of this project is to add information that helps elucidate the role of the Arctic Mediterranean Seas (Arctic Ocean and Nordic Seas) in the climatic system of the Northern Europe. More specifically it has the following aims: - To assess the heat and carbon dioxide fluxes over the air-sea interface in the Barents Sea and elucidate the effect this has on the formation of Arctic Ocean intermediate waters and associated carbon fluxes. - To assess the temporal variability of the fresh water distribution in the Arctic Ocean, both river runoff and sea ice melt, and the affect this has on the outflow of fresh water to the regions of open ocean deep water formation (the Greenland, Iceland and Labrador Seas). - To assess the mixing of upper and intermediate waters along the East Greenland Current that gives the properties of the overflow into the North Atlantic Ocean and thus add to the driving of the thermohaline circulation. This also contributes to the sequestering of anthropogenic carbon dioxide.
