The common scientific interests shared by the Russian Federation and Norway in the Barents Sea have resulted in implementation of the following cooperative research projects:
1. "Geophysical data interpretation and mapping of the Eurasian Basin of the Arctic Ocean in relation to article 76 of the UN Convention of the Law of the Sea" (VNIIOkeangeologia - NPD - University of Oslo). A method for sediment thickness estimation from potential field and seismic data was jointly developed in 2000 - 2001 subsequently applied to a small test area in western Nansen Basin. In 2003-2005 the area of investigation was extended to cover the main part of the Nansen Basin north of the Yermak Plateau and the Franz Josef Land. Principal results of the work, including a new sediment thickness map of the study area, have been published in scientific literature.
2. During the same period VNIIOkeangeologia and NPD carried out a joint investigation to determine coordinated position of the outer limits of continental shelf within the Russian-Norwegian bordering area in the Nansen Basin. The study was based on independent processing and joint analysis of Russian and Norwegian seismic data. A uniform seismic velocity model of the earth’s crust was developed and enabled a more precise delimitation of continental shelf in the study area.
3. "Features of distribution of polycyclic aromatic hydrocarbons (PAH) in marine sediments of the Russian and Norwegian Arctic: percentage levels and identification of sources" (VNIIOkeangeologia - Akvaplan-niva - Norwegian Polar Institute, 2003-2007). This joint activity resulted in creation of a common data base that may be used as source information for subsequent geo-ecological monitoring activities, including estimation of natural organic-geochemical background levels in marine sediments, definition of genesis and main sources of PAH, and compiling maps of distribution of PAH of different origin (biogenic, naphtidogenic, pyrogenic). The project results have been published.
Ongoing research projects "Mesozoic magmatism" and "Mesozoic-Cenozoic uplift" focus mainly on the northern Barents Sea shelf and involve on the Russian side VNIIOkeangeologia and Geological Institute of RAS, with NPD and Statoil as the principal Norwegian partners. Integrated geological and geophysical field activities included both marine studies during 2006-2007 seasons and onshore observations in the Novaya Zemlya, Spitsbergen and Franz Josef Land Archipelagos, followed by joint analytical studies of geological material and cooperative processing of geophysical data.
Joint bio-geochemical investigations of bottom sediment in the Barents and Norwegian Seas are planned under cooperative project with the Institute of Marine Research (IMR, Bergen, Norway).
