The main purpose of our work was to investigate spatial structure and dynamics of the offshore seabird populations and to assess their status in specific conditions of the Baltic Sea marine ecosystem. The main tasks of our work were the following:

• Study species composition, abundance and spatial distribution of seabird populations in different seasons of the year, distinguish dominating species and the most important seabird concentration areas in the eastern Baltic;
• Study community structure of inter-specific assemblages and ecological adaptations of wintering seabird populations;
• Study the processes of spatial dynamics and trends of spatial structure in regional seabird populations within the gradient of winter climatic conditions;
• Study offshore migratory routes and temporary concentration areas of seabirds in the Baltic Proper.
