• To collect information on unusual occurrences of seals along the coast of northern Japan, the questionnaire survey was conducted through the museum, zoos, aquariums and fisheries experimental stations. It revealed that ribbon seal pups unusually occurred along the coast northern Japan in 1984. The white coated pups began to occur in northern area in mid April and after about half month they appeared in southern area. Analysis on both pack ice and oceanographic information suggested that the seal pup dispersion was brought by strong cold current which was particularly prominent in that year.
