Seabirds at sea, june-august 1989 (ship-based observations CvZ/DGW, NIOZ)

From the NIOZ offshore project, data were received from two trips which were actually carried out in May. One on board MV Tridens in the Danish North Sea area and one on the same ship south of the Dogger Bank. Three trips were made on board MV Holland (CvZ/DGW). The first from 20 to 22 June (Terschelling-Dogger Bank and back to waters off Zeeland), the second from 17 to 20 July (same area) and the third from 14 to 17 August (same area). Fulmar densities were highest SE of the Dogger Bank and NW off Esbjerg (Denmark). Gannets were noticed in small numbers (mainly 2nd year birds) in both the coastal zone and further offshore. Manx and Sooty Shearwaters and the Storm Petrel were all recorded once. Off the Wadden Sea islands some flocks of Common Scoters were observed as late as July. Small flocks of migrant waders far from the shore in July and August.
