Chronic oil-fouling of grey seal pups at the Froan breeding ground, Norway

Frequent oil contamination of grey seal Halichoerus grypus pups is shown to be a severe problem within the Froan breeding area off central Norway. Since 1985, annual surveys have revealed that 30–60% of all pups born become oil-fouled during their first month of life. The location of the Froan archi...

Description
Summary:Frequent oil contamination of grey seal Halichoerus grypus pups is shown to be a severe problem within the Froan breeding area off central Norway. Since 1985, annual surveys have revealed that 30–60% of all pups born become oil-fouled during their first month of life. The location of the Froan archipelago within the coastal current serve to accumulate petroleum residues, and the main source of contamination of the pups is beached oil spots that melt when pups lay upon them. The proportion of oil contamined pups therefore increases with time spent ashore.
