Baltic Seabirds Transect Surveys

Original provider: Institute of Ecology of Vilnius University Dataset credits: Gediminas Vaitkus, Institute of Ecology of Vilnius University Abstract: Seabirds transect surveys were conducted in Baltic Sea from 1992 to 1999. Standard seabird offshore sampling techniques assume that line transect of 300 m width is basically used for counting birds sitting on the water surface, whereas the 'snap-shot' method is used for the counting of flying birds at strongly fixed intervals of time. Additional efforts were put into studies of the offshore seabird and waterfowl movements. We recorded flying birds along 1,000 m wide transect over the 'classic' 300 m transect used for calculations of seabird densities during 'snap-shots'.
