Cetaceans and pinnipeds (Southern North Sea and beaches only)

The number of Porpoises seen from coastal sites in Noord Holland in spring has increased considerably in recent years. Following the remarkable group in 1988 (Lagerveld 1988, Sula 2(1):20-21), a series of observations in spring 1989 (see also Sula 3(1):38) is an encouraging sign. Is the Harbour Porpoise returning in our waters? Another interesting series of records is listed below. On 29 March 1989, 4 small herds of Harbour Porpoises were seen moving SSE, swimming slowly in waters between the Dogger Bank and the Bruine Bank.
