Historical data Institute Oceanology Polish Academy of Sciences is doing oceanographic research in the Norwegian, Greenland and Barents Seas since 1987. During summer cruises hydrographic data were collected, some at the same permanent stations and transects. They will be reanalysed to support ASOF research. 2. Observations 2003 AREX2003 cruise of the R.V Oceania was performed in period of June 08 2003 – July 19 2003. CTD (conductivity, temperature, depth) profiles along 14 sections were done (Fig 1, Tab.1). Sections are perpendicular to the general direction of the Atlantic Water flow. The AW domain in the Greenland Sea is situated between Barents Sea slope and underwater ridges system – Mohns Ridge and Knipovich Ridge. Due to convergence of the isobaths in the northern part, AW domain forms wedge, wide in southern part and narrow in the northern end. Specific bottom topography meaningfully influences the currents pattern and structure. Coverage in the southern part of investigated area is spare in comparison to the northern one. This causes less accurate horizontal distribution of properties in the region south of the Bear Island. Our main afford was concentrated in the northern part of Atlantic Domain, where proce
